LED Emergency Driver Buyer Guide<\/h2>\n
A CB-certified emergency driver from a Chinese manufacturer is a modular inverter-battery unit tested under the IECEE CB Scheme to IEC 61347 and relevant national differences, allowing customs and electrical inspectors in CB member countries to accept the certificate without redundant local testing. For buyers shortlisting suppliers, the critical filter is not the CB mark alone but whether the supplier’s CB report covers the specific configuration your host fixture and local code demand.<\/p>\n
The rest of this page maps four decision layers: matching the driver output window to your fixture’s LED module, selecting the emergency duration and lumen percentage your market requires, verifying the CB scope includes those exact ratings, and qualifying the manufacturer’s test data and change-control record.<\/p>\n
Matching Output to Host Fixture<\/h3>\n
Emergency drivers are not universal. The inverter must deliver a DC voltage and current window that overlaps your fixture’s driver-on-board or LED module operating point. Common Hymark configurations include:<\/p>\n
30-50% of normal lumens, 200-400 lm<\/td>\n<\/tr>\n
\n
LED tube 1200 mm<\/td>\n
DC 18-36V, 100-250mA<\/td>\n
2-6W<\/td>\n
30-50% of normal lumens, 150-300 lm<\/td>\n<\/tr>\n
\n
LED linear 1200-1500 mm<\/td>\n
DC 30-55V, 200-500mA<\/td>\n
5-15W<\/td>\n
30-50% of normal lumens, 300-600 lm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
Check whether your fixture needs constant-current emergency output or can accept the simpler resistor-limited design. Constant-current inverters cost 15-25% more but maintain stable lumen percentage across battery voltage sag.<\/p>\n
Emergency Duration and Lumen Percentage by Market<\/h3>\n
Local codes fix the minimum emergency duration and the percentage of normal output the fixture must deliver:<\/p>\n
\n
UK and Ireland<\/strong>: BS 5266-1 and EN 1838 require 90 minutes at minimum 10% of normal output for escape routes, 50% for open areas; many specifiers demand 3 hours for complex buildings<\/li>\n
Mainland Europe<\/strong>: EN 60598-2-22 and EN 62034; 90 minutes standard, 1 hour or 3 hours in specific national annexes; self-test or DALI test facility increasingly mandatory in France, Germany, Benelux<\/li>\n
Middle East<\/strong>: Often 90 minutes or 2 hours; Saudi Arabia and UAE accept CB with local LOA; some projects specify 3 hours for hospitals and malls<\/li>\n
Southeast Asia<\/strong>: Thailand TISI and Vietnam STAMEQ reference IEC; 90 minutes typical; Indonesia requires SNI mark, not CB alone<\/li>\n
Africa<\/strong>: Kenya and Nigeria accept CB; South Africa requires SABS; 90 minutes or 2 hours depending on building type<\/li>\n
Latin America<\/strong>: Brazil INMETRO and Argentina IRAM have their own marks; CB rarely sufficient alone; 90 minutes or 2 hours<\/li>\n<\/ul>\n
A driver rated 3 hours at 4W emergency output with LiFePO4 3.2V 3000mAh pack will deliver roughly 500-800 charge cycles. The same duration with NiCd 3.6V 1800mAh requires a larger cell count or accepts lower wattage. Li-ion 18650 3.7V 2600mAh sits between them on cycle life and energy density but carries stricter transport rules.<\/p>\n

LiFePO4 tolerates higher ambient temperatures in luminaires with poor thermal management. NiCd is cheaper and ships without lithium transport documentation but suffers memory effect and shorter cycle life. For a warehouse high-bay running 45\u00b0C ambient, LiFePO4 is the defensible choice despite 20-30% higher unit cost.<\/p>\n
Wiring Topology: Maintained Versus Non-Maintained<\/h3>\n
Non-maintained wiring energises the emergency driver only on mains failure; the fixture is dark during normal operation. Maintained wiring powers the LED module continuously via the emergency driver or a changeover relay, required in some jurisdictions for exit signs and certain stairwell luminaires. Verify your CB report covers the wiring mode you intend to use; some certificates are restricted to non-maintained only.<\/p>\n
What to Request From the Supplier<\/h3>\n
CB certification is only as good as its scope. Ask for:<\/p>\n
\n
The CB Test Certificate number and the National Certification Bodies (NCB) that issued it<\/li>\n
The CB Test Report covering IEC 61347-2-7 or IEC 61347-2-13 as applicable, with annexes for your target countries<\/li>\n
Declaration of whether the report includes self-test or DALI test facility per EN 62034<\/li>\n
Battery UN 38.3 test summary for lithium chemistries, with IATA and IMDG shipping classification<\/li>\n
IP rating verification; IP20 suffices for inside luminaires, IP65 if driver mounts in the ceiling void<\/li>\n<\/ul>\n
Export Practicalities<\/h3>\n
Hymark ships FOB Shenzhen or CIF to named port. MOQ typically 500-2000 pieces depending on configuration complexity; sample orders of 1-5 units ship within 5-7 working days against confirmed payment. Lead time for volume orders runs 25-35 days after artwork and CB scope confirmation. Lithium battery packs require UN 38.3 certification and must travel as Class 9 dangerous goods by air or sea; carton packing is 20-40 units per carton, palletised for orders above 500 pieces.<\/p>\n

Reduced-Power Emergency Driver<\/h3>\n
This is the volume configuration for OEMs converting standard LED panels, LED tubes and linear fixtures to emergency operation. A 36W 1200mm LED batten typically receives a 3\u20135W emergency driver delivering roughly 500\u2013800 lumens, or 30\u201350% of normal output, for 90 minutes. The battery is usually a LiFePO4 3.2V 3000mAh pack or a NiCd 3.6V 1200mAh pack, with charge times of 16\u201324 hours and cycle lives of 500\u2013800 cycles for lithium chemistry versus 300\u2013500 for NiCd. The constant current inverter output runs at DC 9\u201350V and 150\u2013350mA. Electrical contractors and lighting wholesalers order this by the container for retrofit projects because it avoids rewiring the entire fitting. What it cannot do is meet applications requiring full normal-mode illumination during egress; EN 1838 spacing must be recalculated at the reduced lumen level, and the installer must verify that the host fixture’s LED module will strike reliably at the lower driver voltage.<\/p>\n
Full-Power Emergency Driver<\/h3>\n
Full-power drivers deliver 100% of the host fixture’s rated output\u201415W, 30W, even 60W for LED high bays\u2014requiring proportionally larger battery capacity. A 30W full-power unit for 90 minutes typically carries a LiFePO4 battery pack at 12.8V 4500mAh or multiple Li-ion 18650 cells in 3S2P configuration. The output window is wider, DC 24\u2013240V at 200\u2013700mA, to accommodate the broader LED load range. M&E consultants and lighting designers specify this for retail environments and industrial aisles where EN 1838 minimum illuminance cannot be achieved with reduced-power units at standard spacing. Facility managers with life-safety compliance responsibility favour it because it simplifies lux-level verification. The trade-off is size, weight and cost: the battery pack may be 3\u20134\u00d7 larger than a reduced-power equivalent, and the driver enclosure often requires separate mounting rather than fitting inside a slim linear housing. It cannot economically serve fixtures below 15W normal load.<\/p>\n
Self-Test and DALI-2 Emergency Driver<\/h3>\n
These units embed EN 62034-compliant automatic test circuitry, cycling brief functional tests every 4 weeks and full duration tests annually, with fault reporting via DALI-2 command 35 or local LED status indication. The electrical hardware is identical to reduced or full-power drivers; the premium is in the microcontroller and the relay or semiconductor changeover circuit. Building managers and procurement officers for multi-site portfolios buy these to eliminate manual test-key labour and generate automated compliance logs for fire authority inspection. DALI-2 versions require a DALI bus power supply and addressing during commissioning. What they cannot do is replace the manual test key entirely: BS 5266-1 and most local codes still mandate a physical test facility as backup. They also introduce a failure mode\u2014software or communication fault\u2014that a basic driver does not have.<\/p>\n
Maintained and Non-Maintained Switchable Driver<\/h3>\n
A maintained emergency driver powers the LED from the battery continuously during normal operation, with the battery on float charge; a non-maintained driver keeps the LED off until mains failure, then activates via changeover relay. The same physical driver often supports both modes via terminal block configuration. Maintained mode is required for exit signs and for luminaires that serve as normal room lighting and emergency egress lighting simultaneously, common in UK corridors per BS 5266-1. Non-maintained is preferred where normal and emergency functions are separate circuits. Luminaire OEMs adding emergency versions to their own fixtures order this switchable type to cover both markets with one SKU. The limitation is that maintained mode draws continuous standby power\u2014typically 2\u20135W for the charging circuit plus LED load\u2014which affects building energy calculations. Non-maintained cannot provide instant illumination if the normal circuit fails during occupancy; there is a 0.3\u20131 second relay transfer delay.<\/p>\n
External-Battery Emergency Driver Kit<\/h3>\n
When the luminaire housing has no internal space for a battery pack, or when ambient temperature exceeds 50\u00b0C inside the fixture, the driver module mounts inside and the battery pack mounts remotely on the ceiling or wall. Typical cable runs are 1\u20132m of 0.75\u20131.5mm\u00b2 flexible cord; longer runs require voltage-drop calculation because the battery supplies DC at 3.2\u201312.8V before inversion. The battery chemistry is usually LiFePO4 3.2V 3000\u20136000mAh or, for high-temperature sites, NiCd 3.6V 2500mAh. Charge time remains 16\u201324 hours. This configuration is standard for very slim LED panels under 25mm depth and for bespoke architectural fixtures. Lighting designers and specifiers request it when aesthetics or thermal constraints override integration preference. What it cannot do is tolerate sloppy installation: the external battery pack must carry its own IP rating\u2014typically IP20 for indoor ceiling voids, IP65 if surface-mounted in damp locations\u2014and the interconnecting cable is a vulnerable point for physical damage and accidental disconnection.<\/p>\n
High-Temperature Emergency Driver<\/h3>\n
Industrial LED high bays in foundries, steel mills, Middle East outdoor canopies and commercial kitchens expose emergency drivers to ambient temperatures of 50\u201370\u00b0C. Standard lithium-ion capacity degrades rapidly above 45\u00b0C; high-temperature variants use LiFePO4 cells with improved thermal stability, or remain with NiCd which tolerates 70\u00b0C but at lower energy density and with cadmium content restrictions under EU Battery Regulation 2023\/1542. A 10W high-temperature driver for 90 minutes might use a LiFePO4 6.4V 3000mAh pack with a metal enclosure and thermal pad interface. IEC 61347-2-7 sets abnormal operation and thermal test requirements. Procurement officers for industrial projects in Southeast Asia, Africa and the Middle East specify these explicitly. The limitation is cycle life: even LiFePO4 derates above 45\u00b0C ambient, and a supplier claiming 1000 cycles must substantiate that at the actual operating temperature, not 25\u00b0C laboratory conditions. These units also carry a 20\u201340% price premium over standard-temperature equivalents and cannot be substituted without engineering review.<\/p>\n
LED Emergency Driver assembled and function tested before shipment<\/figcaption><\/figure>\n
Input Voltage Range and Frequency<\/strong> \nThe line “AC 85-265V 50\/60Hz” means the driver accepts any mains voltage between 85 and 265 volts AC, covering North American 120V, Japanese 100V, European 230V and Australian 240V systems. The 50\/60Hz tolerance matters for markets with 60Hz supply such as Saudi Arabia, parts of the Philippines and the Americas. A driver marked “AC 220-240V 50Hz only” is cheaper to build but will fail on 120V sites. Check the label before connecting to a 277V North American commercial circuit; not all wide-range drivers truly tolerate 277V continuously.<\/p>\n
Driven Load in Watts<\/strong> \nThis figure is the normal-mode LED load the driver can switch and supply. The entry-level 10-25W range suits 600\u00d7600mm LED panels at 18-22W. The mid-range 15-40W covers 1200\u00d7300mm linear panels and 1500mm LED tubes in twin arrays. The high-specification 20-60W drives LED high bays and long linear runs. The emergency driver does not boost power; it can only deliver what the battery and inverter section can sustain. A 40W normal fixture driven at 10W emergency output gives roughly 25% of normal luminous flux, which may or may not meet the code minimum for the space.<\/p>\n
DC Output Voltage Window and Current<\/strong> \n“9-42V 350mA” means the driver outputs constant current at 350 milliamps, and the LED forward voltage must fall between 9 and 42 volts DC. The inverter automatically adjusts its output voltage to maintain 350mA. If your LED module wants 48V at 350mA, this driver cannot run it. The mid-range “18-60V 500mA” suits higher-voltage COB arrays and longer LED strings. High-specification “30-80V 700mA” matches high-voltage linear modules. Always verify the LED module’s Vf curve at reduced current; some modules drop below the driver’s minimum voltage window when dimmed to emergency levels.<\/p>\n
Emergency Output in Lumens and Percentage of Normal<\/strong> \nEN 1838 requires minimum illuminance on escape routes, not a fixed percentage, so the datasheet states “50% of normal output” as a design target. A 4000lm panel at 50% emergency output yields roughly 2000lm. For open areas, BS 5266-1 and EN 1838 specify 0.5 lux minimum; a high-bay warehouse may need 10W emergency output to hit this from mounting heights above 4 metres. Ask the supplier for an emergency photometric file or at least a table: “3W output from this driver with 120lm\/W LEDs = 360lm, sufficient for 2.5m corridor width at 2.5m mounting height.”<\/p>\n
Emergency Duration<\/strong> \n90 minutes is the legal minimum across the EU, UK, Middle East and most of Southeast Asia under EN 1838 and BS 5266-1. Two hours appears in some German state regulations and in healthcare specifications. Three hours is common for infrastructure tunnels, stadium concourses and regions with unreliable grid supply such as parts of Africa and South Asia. Longer duration requires larger battery capacity, which increases weight, charge time and transport cost under lithium battery rules.<\/p>\n
Battery Chemistry Voltage and Capacity<\/strong> \nNiCd 3.6V 1500mAh delivers 5.4Wh. At 80% inverter efficiency this gives roughly 4.3Wh usable, supporting 3W for 86 minutes. NiCd tolerates -20\u00b0C but contains cadmium, which triggers RoHS restrictions and waste-battery handling rules in the EU. Li-ion 18650 3.7V 2600mAh stores 9.6Wh, roughly 7.7Wh usable, supporting 5W for 92 minutes. Li-ion has higher energy density but demands UN 38.3 testing for air freight and stricter storage temperature limits. LiFePO4 3.2V 3000mAh stores 9.6Wh with better thermal stability and 1500-2000 cycles versus 500-800 for standard Li-ion. The trade-off is higher cost and lower nominal voltage, which may require 2S1P or 2S2P pack configurations.<\/p>\n
Charge Time<\/strong> \n24 hours for NiCd reflects the slow-trickle chemistry; fast-charging NiCd causes memory effect and reduced capacity. Sixteen hours for Li-ion indicates a CC-CV charge profile at 0.5C rate. Twelve hours for LiFePO4 shows the chemistry’s tolerance for faster charging, though the driver still limits rate to preserve cycle life. A fully discharged battery after a three-hour emergency test needs this full charge period before it can deliver rated duration again.<\/p>\n
Cycle Life<\/strong> \nOne cycle equals one full discharge and recharge. At one monthly functional test per EN 62034, 500 cycles lasts roughly 40 years in theory; in practice, calendar aging limits Li-ion to 8-10 years and NiCd to 5-7 years. The 1500-2000 cycle claim for LiFePO4 is realistic for cell-level testing at 25\u00b0C; at 45\u00b0C ambient, expect 60-70% of rated cycles. Ask the supplier for cycle-life test conditions: “Tested at 1C discharge, 0.5C charge, 25\u00b0C ambient, 80% end-of-life capacity.”<\/p>\n
Test Facility<\/strong> \nManual test key: a physical switch or fuse removal that simulates mains failure. Required by older installations and simple projects. Self-test per EN 62034: automatic monthly functional test and annual duration test with visual status LED. DALI-2: digital addressable lighting interface with emergency commands per Part 252, enabling central reporting, scheduled testing and fault logging. DALI drivers cost 15-25% more and require a DALI bus power supply and controller. Self-test is the practical minimum for commercial buildings; DALI is justified for campuses, hospitals and multi-site portfolios.<\/p>\n
Maintained or Non-Maintained Wiring<\/strong> \nNon-maintained: the emergency driver sits idle until mains fails; the luminaire is dark or lit only by normal mains driver. Maintained: the emergency driver powers the LEDs continuously via a changeover relay, switching to battery only on mains failure. Maintained wiring requires a switched live input so the luminaire can be turned on and off normally while the driver remains energised. Some drivers offer “sustained” mode: a separate emergency lamp inside the same fitting, always on via battery circuit. Check your local code: UK escape routes often require maintained lighting in cinemas and theatres; warehouses typically use non-maintained.<\/p>\n
IP and IK Rating<\/strong> \nIP20: finger-safe, no dust or water protection; install inside luminaire housings or ceiling voids. IP40: protected against 1mm tools and wires; still indoor-only. IP65: jet-proof, suitable for outdoor canopies, car parks and food-processing areas with wash-down. IK04: 0.5 joule impact, roughly equivalent to a 200g ball dropped 250mm. IK06: 1 joule. IK08: 5 joules, sufficient for public areas, sports facilities and industrial corridors. The driver must match or exceed the host fixture’s ratings if mounted externally.<\/p>\n
Ambient Temperature Range<\/strong> \n0\u00b0C to +45\u00b0C is standard office and retail. -10\u00b0C to +50\u00b0C covers unheated warehouses and Middle Eastern facades. -20\u00b0C to +55\u00b0C suits cold storage, Nordic installations and desert environments. Battery capacity drops sharply below 0\u00b0C; a Li-ion pack rated 2600mAh at 25\u00b0C may deliver only 1800mAh at -10\u00b0C. If your application sees -20\u00b0C, specify LiFePO4 or oversized NiCd, and confirm duration by cold-chamber test.<\/p>\n
Dimensions and Mounting<\/strong> \nEntry-level 120\u00d735\u00d722mm fits inside slim 600\u00d7600mm panel back boxes. Mid-range 160\u00d742\u00d728mm requires 40mm minimum void depth. High-specification 200\u00d755\u00d732mm with external battery box may need separate mounting on the luminaire body or ceiling slab. Check the host fixture’s terminal compartment dimensions before ordering. Mounting methods: screw tabs, DIN rail clips, magnetic pads for steel housings, or adhesive-backed aluminium plates.<\/p>\n
Trade Terms and Export Practicalities<\/h3>\n
FOB, CIF, CFR, EXW<\/strong> \nFOB (Free On Board): supplier delivers goods to the port of departure, cleared for export, loaded on vessel. Buyer pays ocean freight and insurance. Common for first-time orders where the buyer has a freight forwarder. CIF (Cost Insurance Freight): supplier arranges shipping to buyer’s port; buyer handles import clearance and inland delivery. Adds 8-15% to unit cost but simplifies logistics for buyers without forwarder relationships. CFR (Cost and Freight): supplier pays freight to destination port; buyer arranges insurance. Rare in lighting; most buyers prefer CIF or FOB. EXW (Ex Works): buyer collects from factory, handles all export clearance and transport. Lowest quoted price but highest buyer burden; suitable only for buyers with China-based agents.<\/p>\n
L\/C and T\/T<\/strong> \nT\/T (Telegraphic Transfer): typically 30% deposit, 70% against copy of bill of lading. Standard for established relationships under USD 50,000. L\/C (Letter of Credit): bank guarantees payment against compliant documents. Adds 1-3% bank charges and requires strict document matching. Justified for first orders above USD 100,000, government tenders, and markets with currency controls such as Nigeria, Egypt and Bangladesh. Some suppliers refuse L\/C for small orders due to document preparation cost.<\/p>\n
HS Code<\/strong> \nLED emergency drivers fall under 8504.40 (static converters) or 8539.31 (parts of electrical lighting equipment). The exact classification affects import duty: 0-4.7% in the EU under 8504.40, potentially higher in protective markets. The supplier’s commercial invoice must state the HS code; discrepancy with the packing list causes customs delays.<\/p>\n
CE and UKCA Marking<\/strong> \nCE marking indicates conformity with EU directives, principally the Low Voltage Directive (2014\/35\/EU) and EMC Directive (2014\/30\/EU). For emergency drivers, the relevant harmonised standards are EN 60598-2-22, EN 61347-2-7 and EN 62034. UKCA marking replaced CE for Great Britain (England, Scotland, Wales) from January 2021; Northern Ireland accepts CE under the Windsor Framework. A buyer should request the supplier’s EU-type examination certificate or test report summary, not accept a CE stamp in isolation. Ask specifically: “Can you provide test reports to EN 60598-2-22:2014+A1:2018 and EN 62034:2012 for the exact model number on the invoice?”<\/p>\n
UN 38.3 Battery Test Report<\/strong> \nAll lithium battery packs (Li-ion and LiFePO4) require UN 38.3 testing before air or sea transport. The test report covers altitude simulation, thermal cycling, vibration, shock, external short circuit, impact\/crush, overcharge and forced discharge. Each battery configuration (cell type, capacity, series\/parallel arrangement, PCM) needs separate testing. Request the UN 38.3 test summary with UN number, proper shipping name, classification and emergency contact. Without this, freight forwarders will reject the shipment or reroute to slower, more expensive cargo-only aircraft.<\/p>\n
Packing List and Certificate of Origin<\/strong> \nThe packing list must show carton dimensions, gross\/net weight, quantity per carton, and total carton count per pallet. Standard export carton for emergency drivers: inner white box with anti-static bag, 50-100 units per master carton, 10-12 cartons per 1200\u00d71000mm ISPM-15 treated pallet. Gross weight per pallet typically 280-340kg including LiFePO4 batteries. Certificate of Origin (CO) is issued by China Council for the Promotion of International Trade (CCPIT) or local customs; required for GCC countries (Saudi Arabia, UAE, Qatar) and for preferential tariff claims under ASEAN-China FTA, RCEP and bilateral agreements. Some Middle Eastern buyers require CO with embassy legalisation, adding 3-5 working days and USD 80-150 per document.<\/p>\n
Matching the Driver to Your Fixture and Market<\/h3>\n
Panel Lights (600\u00d7600mm and 1200\u00d7300mm)<\/strong> \nMost 600\u00d7600mm LED panels draw 36-40W normal and use a 40W normal \/ 5W emergency driver. The driver mounts in the central recess behind the LED module; depth is the constraint, not footprint. For 1200\u00d7300mm panels at 24-30W, a 3W emergency output at 30% may not achieve 0.5 lux in open plan offices; specify 5W minimum or use multiple fittings. UK projects often specify maintained mode for panel installations above desks, requiring switched live wiring to the driver.<\/p>\n
LED Tubes (1200mm and 1500mm T8\/T5 replacements)<\/strong> \nSingle 1500mm LED tubes at 18-22W need 3-5W emergency output. Twin-fitting batten luminaires at 36-44W may use one emergency driver serving both tubes, or one driver per tube for redundancy. The driver’s DC output window must match the tube’s internal driver input: typically 9-18V for integrated-driver tubes, or direct LED string voltage for driverless tubes. Non-maintained is standard for warehouse and car park battens; maintained for circulation areas in healthcare and education.<\/p>\n
Linear Lights (continuous runs, trunking systems, suspended profiles)<\/strong> \nLinear runs of 5-10 metres with 10W\/m LED strip load present a special case. The emergency driver cannot power the full run at normal brightness; it switches to a designated emergency section, or reduces the entire run to 10-20% output. DALI-controlled linear systems can pre-program emergency zones. Check voltage drop: a 48V system at 700mA over 10 metres of 0.75mm\u00b2 cable loses 3-4V, which may push the LEDs below the driver’s minimum voltage window. Specify 1.5mm\u00b2 cable or distribute multiple drivers.<\/p>\n

What Makes Up the Ex-Factory Cost<\/h3>\n
Battery pack<\/strong> \u2014 typically 35% to 50% of the BOM. A 3.2V LiFePO4 3000mAh cell delivers roughly 9.6Wh usable energy. At 4W emergency output with inverter losses, that yields the 90-minute minimum required by EN 1838 and BS 5266-1. A 3.7V Li-ion 18650 2600mAh pack gives 9.6Wh nominal but degrades faster at 45\u00b0C ambient. NiCd 3.6V 1500mAh survives wider temperature swings (-20\u00b0C to +50\u00b0C) but carries heavier metal content and lower energy density. The cell choice determines whether the driver passes the 500-cycle or 1000-cycle endurance tests in EN 62034.<\/p>\n
Driver and inverter electronics<\/strong> \u2014 15% to 25% of BOM. The constant-current inverter stage must hold output within \u00b110% across the battery discharge curve. Changeover relay or solid-state switching must transfer within 0.5 seconds to meet EN 60598-2-22. Input stage handles AC 85-265V or 100-277V depending on target market. Output window is typically DC 9-42V at 150-350mA for panel and linear applications, or DC 180-260V for tube-compatible designs.<\/p>\n
LED package (where integrated)<\/strong> \u2014 5% to 15%. Some emergency drivers include a small LED indicator or test lamp; others drive the host fixture’s existing LED module. The cost varies accordingly.<\/p>\n
Enclosure and hardware<\/strong> \u2014 8% to 12%. IP20 for internal mounting in luminaire cavities; IP65 with gasketed housing for external battery packs in damp or dusty locations. IK08 mechanical impact rating adds polycarbonate lens or metal guard cost.<\/p>\n
Test and certification cost amortised over batch<\/strong> \u2014 5% to 15% depending on volume. ENEC, CB scheme, or UL 924 testing for a new platform typically runs $8,000\u2013$25,000 for the initial report. Spread across a 5,000-unit production run, this adds $1.60\u2013$5.00 per piece. A supplier quoting without this amortisation is either running uncertified product or has not updated test reports for design changes.<\/p>\n
Assembly labour<\/strong> \u2014 3% to 6% for automated SMT plus manual battery pack integration and ageing.<\/p>\n
Export packing<\/strong> \u2014 1% to 2%. Inner carton with foam insert, outer carton 10 pieces, palletised 400\u2013600 pieces for sea freight.<\/p>\n
The Freight and Import Stack<\/h3>\n
Lithium cells trigger transport restrictions under UN 38.3, IATA, and IMDG. Air freight requires UN-certified packaging, hazard labels, and often a 30% freight surcharge. Sea freight accepts lithium under specific stowage and documentation but adds 7\u201314 days transit. Many buyers switch to FOB terms and arrange their own freight forwarder with lithium experience rather than accept CIF from a generalist exporter.<\/p>\n
Inland freight to port (Shenzhen or Jiangmen to Yantian) runs $200\u2013$400 per pallet. Sea freight to UK\/EU ports adds $800\u2013$1,500 per TEU depending on season. Insurance at 110% CIF value is standard. Destination duty for emergency lighting drivers typically falls under HS 8539.50 with rates of 2.7% to 6.5% into the EU, 0% to 6.5% into the UK. VAT at 20% (UK), 19\u201321% (EU), or 5% (UAE) applies to CIF-plus-duty value. Customs clearance and broker fees add $150\u2013$400 per consignment.<\/p>\n
Why the Cheapest Quote Differs<\/h3>\n
The lowest FOB price in any RFQ response normally reflects one or more of these trade-offs:<\/p>\n
\n
Smaller cell<\/strong>: 2000mAh instead of 3000mAh, achieving 90 minutes at 3W instead of 4W, so the host fixture runs at 25\u201330% normal output rather than 50%.<\/li>\n
Reduced emergency output level<\/strong>: Fixed at 30% lumen ratio rather than 50% or 100%, still technically compliant with EN 1838 minimums for escape routes but producing uneven lighting in open plan areas.<\/li>\n
Untested or unlisted design<\/strong>: No valid CB test report, no ENEC mark, no DALI compatibility verification. The driver may function on bench test but fail EMC or safety audit on site.<\/li>\n<\/ul>\n
A buyer should request the supplier’s CB certificate scope (which standards and product codes), the battery cell UN 38.3 test summary, and the DALI test report if self-test functionality is claimed. Without these documents, the “saving” is a compliance liability.<\/p>\n
The entry-level unit costs less than half at purchase but exceeds the mid-range unit’s lifetime cost by Year 2 due to manual testing burden and earlier battery degradation. Facilities with 200+ emergency points see the labour multiplier dominate. This is why M&E consultants specifying to BS 5266-1 increasingly mandate self-test or DALI-addressable drivers despite the higher unit price.<\/p>\n
Matching Configuration to Application<\/h3>\n
For LED panel lights (typical 36W\u201340W normal, 4000 lm), specify a driver with 10W\u201315W emergency output at 100% lumen maintenance if the space is classified as an anti-panic area under EN 1838. For escape routes only, 5W at 50% output (2000 lm) satisfies the 1 lux minimum at floor level in most ceiling heights up to 3m.<\/p>\n
For LED tubes and linear lights, check the output voltage window against the LED module’s forward voltage. A 1200mm tube with 96 LEDs in series may need DC 180-240V; a 600mm linear with 48 LEDs needs DC 90-120V. Ordering the wrong output window means the inverter cannot strike the load or runs at poor efficiency.<\/p>\n
For high-bay and industrial fixtures, external battery packs with IP65 rating and -10\u00b0C to +50\u00b0C ambient range are necessary because the luminaire cavity exceeds Li-ion safe temperatures during normal operation.<\/p>\n
Qualifying the Supplier on Certificates<\/h3>\n
A CB-certified manufacturer should provide:<\/p>\n
\n
CB test certificate and report covering IEC 61347-2-7 (emergency lighting inverters) and IEC 61347-1, with the specific product code listed in the scope.<\/li>\n
Factory ISO 9001 audit status, preferably with IECQ QC 080000 for hazardous substance control if shipping to EU or UK markets.<\/li>\n
UN 38.3 test summary for the exact battery cell model and pack configuration, including T1-T8 test results and the manufacturer’s UN packaging code.<\/li>\n
DALI-2 test evidence if self-test or addressability is claimed, since DALI Part 103 covers emergency testing functions.<\/li>\n<\/ul>\n
Request these before sample order. A supplier who deflects or offers “certificates for similar products” is signalling that the design has not been through full type testing. The buyer then assumes the cost and risk of field failure or customs rejection.<\/p>\n

Commercial Offices and Fit-Outs<\/h3>\n
Open-plan offices with 600x600mm LED panels typically specify 500 to 800 lumens emergency output, roughly 10% of normal 4000-6000 lumen panel output, for 90 minutes under EN 1838. The driver must fit within the 50-70mm ceiling void alongside thermal insulation. A non-maintained wiring configuration is standard: the changeover relay isolates the AC supply and connects the DC inverter only on mains failure. Buyers should verify the self-test module complies with EN 62034 for automatic monthly functional tests and annual duration tests, reducing the need for access equipment in tenanted floors. Ask the supplier to confirm the LiFePO4 pack reaches 80% capacity after 500 cycles at 25\u00b0C ambient.<\/p>\n
Hospitals and Clinics<\/h3>\n
Corridor lighting in healthcare must achieve 1 lux minimum on the floor centreline for 3 hours per BS 5266-1, with maintained wiring so fittings remain live during normal operation and switch to inverter output without a dark period. The driver output window of DC 120-200V suits 15W-30W LED panels; at 30W emergency load a 7.4V 2600mAh Li-ion 18650 pack in 2S2P configuration delivers roughly 3 hours. DALI test interfaces allow integration with building management systems for scheduled test logging. The critical specification is maintained wiring with seamless changeover: verify the relay transfer time is under 0.25 seconds to avoid patient disorientation.<\/p>\n
Warehouses and Logistics Centres<\/h3>\n
High-bay LED fixtures at 10-12 metres require emergency output proportionally higher than office panels to maintain usable illuminance at floor level. A 60W emergency driver at DC 200-260V\/180mA driving a 200W normal LED high bay gives roughly 30% output, yielding 3000-4000 lumens depending on optic efficiency. LiFePO4 12.8V 4500mAh packs tolerate the 35-45\u00b0C ambient common under roof steel in summer. The wide AC 85-265V input accommodates rural or generator-backed supplies. Specify IP65 minimum for dust-laden atmospheres; verify the -10\u00b0C lower limit if cold storage adjacency is possible.<\/p>\n
Car Parks and Stairwells<\/h3>\n
Concrete soffits and exposed steelwork demand IK08 impact resistance and IP65 moisture protection. Surface-mounted battens with 5W-10W emergency output at DC 100-150V\/300mA achieve 100-150 lumens per fitting, sufficient for EN 1838 escape route marking in low-ceiling structures. NiCd 3.6V 1500mAh remains common in budget specifications but carries 18-24 hour charge time and 300-400 cycle life; LiFePO4 3.2V 2000mAh alternatives charge in 12-16 hours and reach 800 cycles. Temperature cycling between winter concrete cold and exhaust heat favours lithium chemistry. Confirm the supplier’s battery pack carries UN 38.3 test documentation for site transport and installation.<\/p>\n
Hotels and Residential Common Areas<\/h3>\n
Corridor downlights in hospitality often operate 18 hours daily, making maintained wiring preferable to avoid lamp cycling stress. A 10W emergency driver at DC 150-200V\/220mA suits 20W-30W normal LED downlights, giving 50% maintained output. The LiFePO4 6.4V 2500mAh pack in 2S1P configuration delivers 90 minutes at 10W with margin. Shallow ceiling voids of 60-80mm depth require driver enclosures under 40mm height. Manual test keys remain common in smaller hotels without BMS integration; verify the test switch wiring is accessible without luminaire removal.<\/p>\n
Retail and Shopping Malls<\/h3>\n
Track lighting and ceiling rafts in retail demand colour consistency between normal and emergency operation. A driver output of DC 180-240V\/200mA at 15W-20W typically yields 1200-1800 lumens from high-efficacy LED arrays, sufficient for 10% of normal output in 3000-4000 lumen track spots. Li-ion 18650 7.4V 2200mAh packs with 500-800 cycle life align with 3-5 year mall maintenance contracts. Self-test functionality per EN 62034 is essential for compliance logging across multi-level centres. Verify the inverter output is constant current, not constant voltage, to prevent LED colour shift as battery voltage declines during discharge.<\/p>\n
Ordering and Importing Step by Step<\/h2>\n
The three mistakes that most often leave a delivered batch unusable are straightforward to prevent with data recorded before you issue a purchase order. Mistake one:<\/strong> ordering an emergency driver with a DC output window\u2014say 50\u2013100V at 300mA\u2014that sits above or below the forward-voltage range of the host fixture’s LED array, so the inverter either cannot strike or runs the LEDs over-current. The fix is to record the host fixture’s nominal LED voltage and current from its normal driver label and match the emergency driver’s constant-current window exactly. Mistake two:<\/strong> specifying 90 minutes duration for a project where the local code or client brief demands 180 minutes, or accepting 10% emergency output when the space needs 50% of normal lumens to meet minimum escape-route illuminance. The fix is to confirm the required duration and the percentage of normal output in writing from the M&E consultant or the authority having jurisdiction before selecting the model. Mistake three:<\/strong> lithium battery packs arriving without UN 38.3 test summaries or the CB test report missing from the customs packet, leading to seizure or demurrage. The fix is to request copies of the battery transport documents and the conformity dossier for the specific destination country before the supplier books cargo.<\/p>\n\n
Matching the Emergency Driver to the Host Fixture<\/h3>\n
The emergency driver is not a standalone product; it is a subsystem that must start the host fixture’s LEDs and keep them lit for the required time from a battery pack. Record these host fixture parameters before you contact any supplier:<\/p>\n
\n
Normal LED driver output:<\/strong> DC voltage range (for example 36\u201372V), rated current (for example 350mA or 700mA), and total wattage (for example 24W or 40W).<\/li>\n
LED array architecture:<\/strong> single string, series-parallel, or linear module; this determines whether the emergency driver’s constant-current output can strike the array at reduced voltage.<\/li>\n
Fixture type and thermal environment:<\/strong> LED panel light, LED tube, or linear trunking; the emergency driver and battery may mount inside the fixture body, in a separate adjacent box, or remotely.<\/li>\n<\/ul>\n
Hymark LED emergency drivers for panels, tubes, and linear lights typically cover host loads from 8W to 60W in emergency mode, with output windows such as DC 25\u201350V at 200mA, DC 50\u2013100V at 300mA, or DC 100\u2013200V at 150mA. The inverter section is constant-current; verify that the host LED forward voltage at the emergency current falls inside the window. If the host fixture uses a high-voltage LED array above 250V, a standard low-voltage emergency driver will not start it.<\/p>\n
Emergency output is expressed as a percentage of normal luminous flux. Common levels are 10%, 20%, 30%, and 50%. EN 1838 requires minimum 1 lux on the centre line of escape routes for open areas and 0.5 lux on anti-panic areas, but the actual percentage you need depends on the host fixture’s normal output and the room geometry. A 4000-lumen panel in a 2.4-metre-wide corridor may need 50% emergency output (2000 lumens) to hit 1 lux at floor level; a 6000-lumen high-bay in a warehouse may achieve the same with 10% (600 lumens) because of wider spacing. Ask the lighting designer or run a point calculation.<\/p>\n
\n
Confirming Duration Output Level and Wiring Mode<\/h3>\n
Duration and output level are locked at order because they determine battery capacity and inverter rating. Standard offerings are 90 minutes, 120 minutes, and 180 minutes (3 hours). BS 5266-1 and many Middle Eastern specifications require 180 minutes for high-occupancy or high-risk premises. EN 60598-2-22 accepts 90 minutes as the default for most locations but does not override stricter national amendments.<\/p>\n

A 40W LED linear light at 50% emergency output (20W) for 180 minutes needs roughly 60Wh usable energy; with inverter and conversion losses, a LiFePO4 12.8V 6000mAh pack (76.8Wh nominal) is typical. A 15W panel at 10% output (1.5W) for 90 minutes runs from a 3.2V 3000mAh single cell (9.6Wh). The supplier should state the driven load in watts and the actual emergency lumens, not just the percentage.<\/p>\n
Choose maintained<\/strong> or non-maintained<\/strong> wiring before ordering. Non-maintained: the emergency driver sits idle until mains failure, then the changeover relay switches the LED array to the inverter. Maintained: the emergency driver also supplies the LEDs during normal operation, or a separate switched live keeps the indicator live; the wiring diagram differs and the driver must support dual feed. The changeover relay rating\u2014typically 2A or 5A at 250VAC\u2014must handle the host fixture’s inrush if maintained.<\/p>\n\n
Selecting Test Facility and Control Protocol<\/h3>\n
The test facility is a functional requirement, not an accessory. Options are:<\/p>\n
\n
Manual test key:<\/strong> a switch or key switch on the driver housing; the installer or building manager initiates a 30-second or full-duration test. Lowest cost, highest labour burden.<\/li>\n
Auto self-test:<\/strong> the driver runs a brief functional test every 30 days and a duration test annually, with LED status indication (green\/red). Complies with EN 62034 for automatic testing of emergency luminaires.<\/li>\n
DALI self-test:<\/strong> the same automatic schedule, plus reporting of fault and readiness status over the DALI bus to the central emergency lighting monitoring system. Requires DALI-compatible host fixture wiring and a DALI controller.<\/li>\n<\/ul>\n
If the project specification cites BS 5266-1 or the client operates a large estate, DALI self-test is often mandatory. Confirm the protocol version (DALI-1 or DALI-2) because emergency commands differ. A driver with self-test but no DALI cannot be retrofitted to DALI later without replacement.<\/p>\n

However, if the host fixture is a 100\u2013277V normal driver for North American projects, confirm the emergency driver also accepts the local nominal (for example 120V) and does not drop out at the low end of tolerance.<\/p>\n
For the CB certificate search implied by your query: CB scheme test reports under IEC 61347 (for controlgear) and IEC 60598-2-22 (for luminaires) are accepted by many national certification bodies as partial evidence, but the CB report alone does not replace the local mark. Ask the supplier for the CB test report number, the IEC standard edition, and whether the report covers the exact battery chemistry and capacity you intend to order. A CB report for a NiCd variant does not cover a LiFePO4 variant.<\/p>\n

IP Rating Ambient Temperature and Mounting Position<\/h3>\n
The emergency driver and battery pack must survive where they are mounted:<\/p>\n
\n
IP rating:<\/strong> IP20 for indoor driver compartments; IP65 if mounted in a damp location, exterior soffit, or industrial canopy where water ingress is possible.<\/li>\n
Ambient temperature range:<\/strong> standard drivers are rated \u221210\u00b0C to +45\u00b0C or \u221220\u00b0C to +50\u00b0C. Battery capacity derates below 0\u00b0C; LiFePO4 tolerates \u221220\u00b0C better than Li-ion 18650, but charge acceptance still suffers. If the mounting position is a hot roof void above 50\u00b0C, specify high-temperature cells or remote mounting of the battery to a cooler zone with extended cable.<\/li>\n
IK rating:<\/strong> IK07 or IK08 if the driver is surface-mounted in a public or industrial space vulnerable to impact.<\/li>\n<\/ul>\n\n
Ordering and Import Checklist<\/h3>\n
Use this numbered checklist to structure your RFQ and pre-shipment verification.<\/p>\n
\n
Record host fixture data.<\/strong> Write down the normal driver output voltage range, current, wattage, LED array configuration, and fixture type (panel, tube, linear). Match the emergency driver’s DC output window and constant-current set point exactly.<\/li>\n
Confirm required emergency duration.<\/strong> Specify 90 minutes, 120 minutes, or 180 minutes in writing. Confirm the percentage of normal output (10%, 20%, 30%, 50%) needed to achieve the design illuminance on the escape route.<\/li>\n
Choose maintained or non-maintained wiring.<\/strong> Obtain the wiring diagram from the supplier and verify the changeover relay rating against the host fixture inrush current.<\/li>\n
Select test facility.<\/strong> Decide manual test key, auto self-test, or DALI self-test per EN 62034. If DALI, confirm DALI-1 or DALI-2 compatibility with the project’s lighting management system.<\/li>\n
Confirm mains voltage and frequency.<\/strong> Verify the emergency driver input range covers the site nominal plus tolerance; for example AC 85\u2013265V, 50\/60Hz for universal coverage, or AC 220\u2013240V for single-voltage markets.<\/li>\n
Request conformity documentation.<\/strong> Ask for the CB test report (IEC 61347 and\/or IEC 60598-2-22), the specific edition, and the covered variants. Ask what local marks (CE, UKCA, G-Mark, SIRIM, etc.) the supplier can support and whether they hold the certificate or rely on a sub-supplier’s licence.<\/li>\n
Check IP and ambient limits.<\/strong> Specify IP20, IP65, or other; state the ambient temperature range at the mounting position; confirm battery chemistry (LiFePO4, Li-ion 18650, NiCd) and whether it tolerates the site conditions.<\/li>\n
Agree MOQ and sample approval.<\/strong> Typical MOQ for LED emergency drivers is 500 to 1000 units for standard models, with lower MOQ for customised output windows or battery packs. Order two to five samples: one for electrical verification, one for thermal and duration test, one for destructive battery analysis if lithium. Approve the sample batch report before mass production.<\/li>\n
Require batch duration test records.<\/strong> Every production batch should have 100% functional test and sampled duration test records. Ask for the sampling plan (for example IEC 60410 General Inspection Level II, AQL 1.0 for critical defects).<\/li>\n
Arrange lithium battery shipping documents.<\/strong> If the battery is Li-ion 18650 or LiFePO4, require UN 38.3 test summaries for the exact cell model and configuration. For air freight, the pack must be at 30% state of charge or less, and the cargo-only aircraft limit is typically 35kg net lithium content per package; for sea freight (IMDG), require the shipper’s dangerous goods declaration. NiCd packs have lighter transport rules but still require proper labelling.<\/li>\n
Specify carton and pallet packing.<\/strong> Individual boxes typically hold 20 to 50 drivers; outer cartons should list model, quantity, gross weight, and battery chemistry. Pallets should be fumigation-free ISPM-15 compliant for EU and UK; maximum pallet height 1.6m or 2.0m per carrier rules. Label with handling symbols and, for lithium, Class 9 dangerous goods labels.<\/li>\n
Plan commissioning and first annual test.<\/strong> On site, record the installed location, circuit number, and test date. Run a manual or DALI-initiated functional test to verify strike and transfer. Schedule the first annual duration test per BS 5266-1 or local rule; for self-test systems, verify the 30-day and annual test schedule is active in the DALI controller or driver memory.<\/li>\n<\/ol>\n\n
Supplier Qualification Beyond the Data Sheet<\/h3>\n
A CB-certified manufacturer in China should demonstrate in-facility capability, not just a certificate held by a trading company. Ask for: the scope of the CB factory inspection report (CIG 023 programme); whether the factory owns the SMT lines, inverter assembly, and battery pack welding stations; and whether they can produce a witnessed duration test on your sample during a video factory audit. Battery pack consistency is the most common failure mode in emergency drivers; a supplier who assembles cells in-house with a battery management system (BMS) test rig is preferable to one who sources finished packs from an uncertified third party.<\/p>\n
Lead times from confirmed sample approval are typically 30 to 45 days for standard models, 45 to 60 days for customised output windows or special battery configurations. Sample lead time is 7 to 14 days ex-works. Payment terms for first orders are commonly 30% deposit, 70% against copy of bill of lading; negotiate after established trading history.<\/p>\n
