Commercial Building Safety Lighting Manufacturerin Buyer Guide<\/h2>\n
UN 38.3; IATA DGR compliance for lithium<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
Procurement officers and M&E consultants evaluating Chinese suppliers should verify four elements before shortlisting. First, request the supplier’s UN 38.3 test summary for each lithium battery SKU\u2014customs in Heathrow, Dubai, and Lagos now routinely hold shipments without this document. Second, confirm the factory’s actual output window tolerances, not just nominal values; a driver rated “25\u201350V DC” that sags to 22V at end-of-discharge will extinguish the LED module before the rated duration. Third, ask for third-party thermal test reports to EN 60598-2-22 clause 16, not just EMC or LVD certificates, because thermal runaway in enclosed high bays is the dominant failure mode in the field. Fourth, understand the MOQ and lead time reality: emergency drivers with custom output windows typically require 500\u20131,000 units MOQ with 4\u20136 weeks lead time; twin spotlights as standard SKUs may start at 300 units with 3\u20134 weeks. Sample policy varies\u2014some factories charge 150\u2013200% of FOB unit price for single samples plus air freight; others credit the sample cost against the first production order above 1,000 units. FOB Shenzhen or CIF destination are standard terms; buyers should budget 5\u20138% for freight insurance and destination port charges on CIF shipments.<\/p>\n

Reading the Input Voltage and Frequency Line<\/h3>\n
The first line on any emergency driver datasheet tells you where the product can be installed. AC 220-240V 50Hz covers the UK, Europe, Middle East and most of Africa. AC 100-277V 50\/60Hz adds North America, Japan and parts of Southeast Asia. AC 85-265V is the widest universal range. Check that the frequency matches: 50Hz in Europe, 60Hz in the Americas, dual-frequency units suit mixed export stock. A driver rated only 220-240V will fail or shut down on 120V mains. Ask the supplier for the specific range printed on the unit label, not marketing claims.<\/p>\n
Understanding Driven Load and DC Output<\/h3>\n
“Driven load in watts” is the LED power the driver replaces in emergency mode. The DC output voltage window and current define compatibility. A constant current inverter might output 25-40V DC at 1500mA. Your host fixture’s LED module must sit inside that voltage window. If the LED forward voltage is 54V, this driver cannot run it. The current figure determines brightness: 350mA is typical for reduced-output emergency, 1500mA for full-power maintained output. The changeover relay switches between mains and battery supply; check whether it is internal or requires external wiring.<\/p>\n
Emergency Output in Lumens and Percentage of Normal<\/h3>\n
EN 1838 and BS 5266-1 specify minimum illuminance on escape routes, not driver watts. The datasheet should state emergency output in lumens and as a percentage of normal output. Entry-level twin spotlights often run 100% of normal (200 lm from a 3W head) because the normal output is already low. Mid-range drivers for high bays typically deliver 10% of normal (500 lm from a 50W fixture) to meet the 1 lux minimum on the floor. Full-power emergency drivers deliver 100% of normal (3000 lm from a 150W panel) for open-area anti-panic lighting or high-risk task areas. Verify which applies: 10% is standard for escape routes, 100% is required for operating theatres, plant rooms and some industrial processes.<\/p>\n
Emergency Duration and Battery Chemistry<\/h3>\n
Emergency duration is 90 minutes, 2 hours or 3 hours depending on local code. UK and Europe default to 3 hours for most premises under BS 5266-1. The US under NFPA 101 and UL 924 typically requires 90 minutes. Australia under AS\/NZS 2293 specifies 90 minutes for Class W, 2 hours for Class C. Battery chemistry determines whether you can meet these durations reliably.<\/p>\n
NiCd 3.6V 1500mAh packs are the legacy choice: robust temperature tolerance, roughly 300-500 cycles, but 24-hour charge time and cadmium content restricts EU sales under RoHS exemptions. Li-ion 18650 7.4V 2600mAh packs halve charge time to 6 hours and extend cycle life to 500-800 cycles, but thermal runaway risk requires UN 38.3 test reports for air freight. LiFePO4 12.8V 3000mAh packs deliver 1500-2000 cycles, 4-hour charge, and safer thermal profile, at higher unit cost and weight. Match chemistry to duty: frequent testing favours LiFePO4, cost-sensitive projects with stable mains may accept NiCd where legally permitted.<\/p>\n
Test Facility Options<\/h3>\n
Manual test key is the minimum: a physical switch or fuse removal simulating mains failure. Self-test per EN 62034 automates this monthly and annually, reporting via LED status indicator. DALI test facility integrates with building management systems, logging test results with time stamps and fault codes. DALI drivers cost 15-25% more and require DALI bus wiring. Specify self-test for standalone installations, DALI for managed estates with maintenance contracts.<\/p>\n
Maintained Versus Non-Maintained Wiring<\/h3>\n
Non-maintained wiring powers the emergency LEDs only during mains failure. The live feed charges the battery; no neutral connection to the lamp in normal operation. Maintained wiring runs the lamp from mains in normal mode and switches to battery on failure, requiring a switched live plus permanent live. Some drivers accept either configuration via terminal selection; others are dedicated non-maintained. Luminaire OEMs must design the host fixture PCB accordingly. Confirm with the supplier’s wiring diagram before ordering.<\/p>\n
IP Rating IK Rating and Ambient Temperature<\/h3>\n
IP20 suits dry interior voids and electrical enclosures. IP65 is standard for dust-tight and jet-proof installation in warehouses, car parks and tunnels. IK04 withstands 0.5 joule impact; IK08 withstands 5 joule, required for vandal-prone or industrial locations. Ambient temperature range of 0\u00b0C to +45\u00b0C is typical for NiCd; LiFePO4 extends to -20\u00b0C to +60\u00b0C. Battery capacity derates below 0\u00b0C: a 3000mAh pack may deliver only 70% at -10\u00b0C, reducing emergency duration proportionally. Specify winter minimums if the installation includes unheated plant rooms or external bulkheads.<\/p>\n
Dimensions Mounting and Strip-Specific Parameters<\/h3>\n
For emergency drivers, dimensions determine fit inside the host fixture body. A 240 \u00d7 80 \u00d7 45 mm driver requires a minimum 250 \u00d7 90 \u00d7 50 mm void plus cable clearance. Mounting is typically via M4 screws or magnetic bracket for steel high bays. For SMD LED strips used in cove or linear emergency luminaires, additional parameters apply:<\/p>\n

Higher LED density (240\/m versus 60\/m) improves uniformity in shallow diffusers but increases power density and heat. Copper weight affects voltage drop over long runs: 2 oz copper maintains brightness at 10 metres where 1 oz copper would dim by 15%. CRI Ra 90 is standard for retail and healthcare; Ra 80 suffices for industrial escape routes. Colour temperature must match the normal lighting: 4000K emergency against 3000K normal creates visual discontinuity that disorientates occupants.<\/p>\n
Trade Terms and Export Practicalities<\/h3>\n
FOB (Free On Board) means the supplier delivers to the port of departure, loaded on vessel. CFR (Cost and Freight) adds ocean freight to your port; CIF (Cost Insurance Freight) adds marine insurance. EXW (Ex Works) places all transport risk and arrangement on you from the factory door. For first orders, CIF to your nearest port minimises logistics coordination. T\/T (telegraphic transfer) is standard payment: 30% deposit, 70% against copy of bill of lading. L\/C (letter of credit) adds bank fees of 1-3% but protects both parties; suitable for orders above USD 50,000 where trust is unestablished.<\/p>\n
Conformity Marks and Documentation<\/h3>\n
CE marking is required for EU customs clearance; UKCA for Great Britain post-Brexit. The supplier must provide a declaration of conformity and technical file, but verify the specific standards referenced: EN 60598-2-22 for emergency luminaires, EN 62034 for self-test systems, IEC 61347 for control gear. Do not assume CE on the label covers all applicable standards; ask for the test report summary.<\/p>\n
UN 38.3 battery test report is mandatory for lithium battery air freight and often requested for sea freight by forwarders. The report covers altitude simulation, thermal cycling, vibration, shock, external short circuit, crush and forced discharge. Without it, IATA and IMDG regulations block shipment. Ask for the UN 38.3 test summary with battery cell manufacturer, model and watt-hour rating.<\/p>\n
HS code 9405.10 covers emergency lighting; 9405.40 covers LED strips. The packing list should state gross and net weight, carton dimensions and battery watt-hours per carton. Certificate of origin (Form A or EUR.1) may reduce duty under trade agreements. MOQ for emergency drivers typically ranges 100-500 units; LED strips 500-2000 metres. Lead time is 25-35 days for standard builds, 45-60 days for customised output voltages or DALI firmware. Sample policy: paid samples refunded against first order, or kept at cost for evaluation.<\/p>\n

What Drives the Factory Price<\/h3>\n
The ex-works price of a commercial emergency luminaire or driver is not arbitrary. It tracks six material categories plus certification amortisation and logistics. Understanding the split helps a buyer evaluate why one factory quotes USD 22 and another quotes USD 45 for what looks like the same datasheet.<\/p>\n
Battery cells.<\/strong> The pack is normally the single most expensive component. A 3.2V LiFePO4 3000mAh cell delivers roughly 9.6Wh and supports 500\u2013800 full cycles. A 3.7V Li-ion 18650 2600mAh cell delivers 9.6Wh but 300\u2013500 cycles. NiCd 3.6V 1500mAh delivers less energy density, 500\u2013700 cycles, and carries environmental disposal obligations. For a 10W emergency output over 90 minutes, the inverter draws approximately 15Wh including conversion losses, so the pack needs 12\u201318Wh nominal capacity. A twin spotlight with two 3W heads running 3 hours needs 18\u201324Wh. The cell chemistry choice alone can swing the battery line item from 20% to 35% of BOM cost.<\/p>\n
Driver and inverter electronics.<\/strong> The emergency driver contains a constant-current inverter stage, changeover relay or solid-state switch, charging circuit, and protection logic. Output windows vary: 9\u201360V DC at 150\u2013350mA for linear LED arrays; 200\u2013700mA for high-bay COB modules. EN 62034 requires the changeover time not to exceed 0.25 seconds in maintained mode. A self-test microcontroller adds USD 2\u20134; DALI-2 test interface adds USD 4\u20137.<\/p>\n
LED package.<\/strong> Twin spotlights use discrete SMD 2835 or 5730 packages. Emergency drivers for OEM fixtures rely on the host luminaire’s LED board, so the driver BOM excludes LEDs but must specify compatible forward-voltage ranges.<\/p>\n
Enclosure and hardware.<\/strong> IP65 die-cast aluminium with tempered glass for outdoor twin spots; IP20 steel for recessed panel drivers. IK08 or IK09 rating for vandal-prone locations adds machining cost.<\/p>\n
Test and certification cost amortised over the batch.<\/strong> EN 60598-2-22 and EN 1838 require photometric testing, thermal ageing, and endurance trials. A third-party CB test report or ENEC certificate for a new family costs USD 8,000\u201318,000. Spread across a 2,000-unit first batch, this is USD 4\u20139 per piece. Spread across 20,000 units, USD 0.40\u20130.90. A factory without existing reports may quote low and absorb this later, or may never obtain it. Buyers should request the test report number and the issuing body’s online verification link.<\/p>\n
Assembly labour.<\/strong> Shenzhen and Dongguan emergency lighting factories run semi-automated SMT for PCBs and manual assembly for battery packs and final test. Labour content is 8\u201315% of factory cost.<\/p>\n
Export packing.<\/strong> Individual colour box, master carton 12\u201324 pieces, palletised to 400\u2013600 kg per cubic metre for sea freight. UN 38.3 lithium battery packing requires fibreboard UN 4G boxes, lithium handling labels, and limited quantities per consignment if air freighted. This adds 5\u201310% to logistics cost versus NiCd or non-battery goods.<\/p>\n
Why the Cheapest Quote Differs<\/h3>\n
The lowest factory offer typically reflects one of three shortcuts:<\/p>\n
\n
Smaller cell.<\/strong> A 1500mAh pack instead of 3000mAh meets 90 minutes at reduced output but fails at 3 hours, or delivers 50% lumen maintenance instead of 70% at end of discharge.<\/li>\n
Reduced emergency output level.<\/strong> The unit achieves duration by dimming to 5% of normal instead of 10% or 25%, violating EN 1838 minimum illuminance requirements for escape routes.<\/li>\n
Untested design.<\/strong> No third-party thermal or photometric validation. The factory may have self-declared CE marking without accredited testing. Customs in the EU, UK, or Australia can detain goods without traceable test evidence.<\/li>\n<\/ul>\n

The mid-range unit breaks even by year 4 and avoids the compliance risk of dead batteries in an actual emergency. For maintained installations in hospitals or data centres, the cost of a single evacuation event dwarfs the hardware saving.<\/p>\n
Matching Product to Host Fixture and Local Code<\/h3>\n
Twin spotlights<\/strong> suit open areas, warehouses, and loading bays where the normal luminaire has no emergency provision. Specify 10% normal output minimum for open areas per EN 1838, or 1 lux minimum on the floor centre line for escape routes. Non-maintained wiring is standard; maintained requires a permanent live plus switched live, complicating cable runs but allowing the unit to contribute to normal illumination.<\/p>\n
Emergency drivers for LED high bays<\/strong> fit OEM fixtures where the normal driver is external or accessible. The driver output must match the LED module Vf: 30\u201360V for mid-power arrays, 180\u2013260V for high-voltage COB strings. Input voltage range 100\u2013277V AC covers North America and Southeast Asia; 220\u2013240V AC for UK, Europe, Middle East, and Africa. A 25W emergency output on a 200W high bay gives 12.5%\u2014verify this meets the local minimum, typically 10% for open areas, 25% for anti-panic areas.<\/p>\n
SMD LED strips<\/strong> are not standalone emergency products. An emergency-rated strip installation requires a compatible inverter\/driver and battery pack, with the strip serving as the load. Specify 60 LEDs\/m at 14.4W\/m, 24V DC, 5mm cut length for 2835 chips, 10mm for 5050, on 2oz copper PCB for thermal management. CRI 80+ for general commercial, 90+ for retail or healthcare. Colour temperature 4000K is standard for escape routes; 3000K for hospitality.<\/p>\n
Supplier Qualification Checklist<\/h3>\n
Buyers shortlisting Chinese emergency lighting manufacturers should verify:<\/p>\n
\n
Test report traceability.<\/strong> Request the CB report reference, the NCB\/CBTL name, and the product category (IECEE OD-2040 for luminaires). Cross-check on the IECEE website. For UKCA, ask for the UK approved body number and the EN 60598-2-22 scope on their accreditation schedule.<\/li>\n
Battery documentation.<\/strong> UN 38.3 test summary for lithium cells, including the T1\u2013T8 test results and manufacturer. IATA Section II or Section IB packing instructions for air freight samples. IMDG Code SP 188 or 230 for sea freight.<\/li>\n
Production consistency.<\/strong> Ask for the critical component list (CCL) from the test report and compare against the quotation BOM. A swapped cell brand or reduced copper weight invalidates the certificate.<\/li>\n
Sample policy.<\/strong> Expect to pay USD 80\u2013150 per sample including air freight with lithium labelling. Factories unwilling to ship UN 38.3 compliant samples may lack the documentation for production volumes.<\/li>\n
MOQ and lead time.<\/strong> 500\u20131000 units for standard twin spots; 200\u2013500 for emergency drivers with custom output windows. Lead time 25\u201340 days after order confirmation for existing certified designs; 55\u201375 days if new testing is required.<\/li>\n<\/ul>\n

Lithium battery transport rules constrain shipping. UN 38.3 tested cells are mandatory for air and vessel carriage. IATA limits lithium-ion cells to 30% state of charge for air freight; IMDG Code permits higher SOC under SP 188 for sea freight if properly packed. FOB Shenzhen or FOB Hong Kong terms place inland freight and export clearance on the seller; CIF terms add sea freight and insurance to the buyer’s port. For emergency lighting with lithium packs, sea freight is normally 30\u201340% cheaper than air and avoids the IATA quantity restrictions that can split shipments.<\/p>\n
The battery pack and third-party approval are the two dominant cost drivers. A buyer who understands this can read a quotation intelligently: ask for the cell part number, the Wh rating, the test report reference, and the CCL. Everything else follows.<\/p>\n

AS\/NZS 2293 in Australasian markets requires classification by building use; hospitality often needs maintained for 24\/7 ambience<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
Commercial Offices and Fit-Outs<\/h3>\n
Open-plan offices with suspended LED panels and linear trunking systems need emergency conversion that does not disrupt ceiling aesthetics. A 3W non-maintained LED emergency driver fed from AC 85-265V, outputting 150-250V DC at 150mA, drives a 20-40W LED panel at roughly 10-15% of normal lumen output for 90 minutes. The LiFePO4 3.2V 2200mAh pack charges in 24 hours and delivers 500-800 cycles. Buyers should ask suppliers for EN 60598-2-22 test reports covering the specific panel wattage, because lumen depreciation in emergency mode must still achieve 1 lux on the escape route centre line per EN 1838. Maintained wiring adds cost and complexity; most office fit-outs opt for non-maintained unless the space doubles as public assembly.<\/p>\n
Hospitals and Clinics<\/h3>\n
Healthcare facilities present the strictest duration requirement in the table. BS 5266-1 and HTM 06-01 both specify 3 hour emergency duration for patient-accessible areas, with maintained operation preferred so lamps never extinguish during generator changeover. A 7.4V Li-ion 18650 2600mAh pack feeding a constant-current inverter through a changeover relay sustains a 10-15W LED downlight at 30-50% output for 180 minutes. Self-test or DALI-automated testing is near-mandatory given the scale of hospital estates; manual test keys on 500+ fittings are not practicable. The trade-off is battery chemistry: Li-ion 18650 packs need battery management systems and thermal monitoring, adding cost versus LiFePO4, but achieve higher energy density for the 3 hour load.<\/p>\n
Warehouses and Logistics Centres<\/h3>\n
High-bay spaces at 8-15 metre mounting height cannot rely on low-level bulkheads alone. LED high bays of 100-200W normal load need dedicated 10-25W emergency drivers outputting 200-240V DC at 80-120mA to achieve meaningful lumen packages\u2014typically 800-1500 lumens emergency versus 15,000-20,000 lumens normal. Twin spotlights with adjustable heads provide an alternative: two 3W LED heads on a single 6.4V LiFePO4 3000mAh pack, each head delivering 300-400 lumens for 90 minutes, aimed down racked aisles. IP65 is standard for dusty environments; IK08 matters where forklift traffic occurs. The buyer should verify the supplier has tested the driver at the actual ambient temperature of the warehouse roof void, often 45-55\u00b0C in summer, as battery capacity derates above 25\u00b0C.<\/p>\n
Retail and Shopping Malls<\/h3>\n
Retail environments combine public safety compliance with brand continuity. Cove and display lighting using SMD LED strips at 14.4W\/m, 120 LEDs per metre, 3000K, CRI>80, 1080 lm\/m, running on 24V DC, can be backed up by maintained 3W emergency drivers with LiFePO4 3.2V 1500mAh packs. The driver switches the strip to reduced output\u2014typically 30% of normal, 324 lm\/m\u2014rather than full extinguishment, preserving some ambience and preventing panic. EN 60598-2-22 applies to the complete luminaire assembly; if the OEM builds the strip into a custom fitting, the emergency driver must be certified as part of that assembly or the OEM assumes compliance liability. Charge time is 16-20 hours for the 1500mAh pack; cycle life 600-900.<\/p>\n
Car Parks and Stairwells<\/h3>\n
These are the most mechanically and environmentally stressed installations. Surface bulkheads and twin spots in multi-storey car parks need IP65 against water and chemical washdown, IK08 against vehicle impact, and often 3 hour duration because fire service access may be prolonged. A 6.4V LiFePO4 3000mAh pack driving two 2W LED heads at 400 lumens each achieves 90 minutes comfortably; for 3 hours, either a 4500mAh pack or reduced output to 250 lumens per head is required. EN 1838 mandates 15 lux on stair treads and 5 lux in open car park driving lanes; the specifier must calculate spacing based on actual photometric files, not generic mounting height tables. Non-maintained wiring is standard; maintained adds no safety benefit in intermittently occupied spaces.<\/p>\n
Hotels and Residential Common Areas<\/h3>\n
Hospitality corridors and apartment common areas balance life safety with guest experience. Maintained operation keeps corridor downlights at reduced level during normal hours, avoiding the jarring switch to emergency during power failure; non-maintained is acceptable where corridor lighting is already on presence detection. A 3W driver with LiFePO4 3.2V 2200mAh, 90 minute or 2 hour duration, AC 220-240V input, outputting 150-200V DC at 100mA, suits typical 12-18W LED downlights. Manual test key versions suit small hotels; DALI self-test becomes cost-effective above 50 fittings. For export to Australasia, AS\/NZS 2293 classification as Class C (maintained) or Class D (non-maintained) must be marked on the product and documentation; buyers should request supplier evidence of this classification before shipment.<\/p>\n
Ordering and Importing Step by Step<\/h2>\n
Three mistakes regularly leave delivered emergency lighting batches unusable on arrival. Output window mismatch:<\/strong> the emergency driver delivers 50V DC to a fixture whose LED module needs 25\u201336V DC; the lamp stays dark in emergency mode. Fix: record the host fixture’s nominal LED voltage and current before selecting the inverter module. Duration or illuminance shortfall:<\/strong> a 90-minute driver is installed where BS 5266-1 or local code demands 3 hours, or the 5% emergency output produces 2.5 lux on the floor instead of the required 3 lux along the escape route. Fix: confirm the mandated duration and minimum maintained illuminance with the project’s fire safety engineer before ordering. Documentation gaps at customs:<\/strong> lithium battery shipments arrive without UN 38.3 test summaries or the conformity mark the destination country requires, triggering seizure or return. Fix: request battery transport documentation and valid test report references in writing before payment.<\/p>\n\n
Host Fixture Matching<\/h3>\n
Order the emergency module to the host, not the other way around. Record these five parameters from the normal fixture before contacting any supplier:<\/p>\n
\n\n
\n
Parameter<\/th>\n
What to Record<\/th>\n
Why It Matters<\/th>\n<\/tr>\n<\/thead>\n
\n
\n
LED module voltage<\/td>\n
Nominal Vf range, e.g., 25\u201336V DC or 180\u2013260V DC<\/td>\n
Determines the inverter output window; constant-current inverters are rated for a specific DC voltage range<\/td>\n<\/tr>\n
\n
LED module current<\/td>\n
mA, e.g., 350mA, 700mA, 1050mA or 1400mA<\/td>\n
The inverter must deliver this current without over-driving the LEDs<\/td>\n<\/tr>\n
\n
Normal driver wattage<\/td>\n
W, e.g., 40W, 100W, 150W, 200W<\/td>\n
Emergency output is a percentage of this; 10% of 150W is 15W, 5% is 7.5W<\/td>\n<\/tr>\n
\n
Driver architecture<\/td>\n
Isolated high-voltage output, linear constant-current, or integrated LED + driver module<\/td>\n
Affects whether the emergency driver replaces the normal driver or sits in parallel via changeover relay<\/td>\n<\/tr>\n
\n
Physical space<\/td>\n
Length \u00d7 width \u00d7 height inside the fixture housing or in a separate enclosure<\/td>\n
Battery packs for 3-hour duration at high wattage need more volume; twin-spotlight heads need clearance<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
For LED high bays and linear panel lights, Hymark’s LED emergency drivers for LED high bays typically cover 40W to 200W normal load with emergency output options of 5%, 10%, 20% or full power. Output windows range from 25\u201342V DC at 350\u2013700mA for low-voltage modules up to 180\u2013260V DC for high-voltage linear systems. SMD LED strips used in cove or bulkhead emergency lighting run at 24V DC or 48V DC with 60 LEDs per metre, 14.4W\/m, 1200\u20131500 lm\/m at 4000K, CRI 80+; verify the strip’s cut length (typically 50mm or 100mm) and PCB copper weight (2oz preferred for thermal management) match the emergency driver’s constant-voltage output.<\/p>\n\n
Duration and Emergency Output Level<\/h3>\n
Local codes define both the minimum duration after mains failure and the minimum illuminance the emergency source must provide. Common configurations:<\/p>\n
Small offices, retail, some Middle East jurisdictions<\/td>\n

5% to 10% of normal, or full power for open areas<\/td>\n
5% of 200W = 10W, ~1000 lm; full power = 200W, ~20,000 lm<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
EN 1838 requires 1 lux minimum on the centre line of escape routes and 0.5 lux on anti-panic open areas; BS 5266-1 adds specific requirements for high-risk task areas. Ask the supplier for photometric data or a point-by-point calculation showing the fixture’s emergency output achieves these levels at the installed mounting height. A 10% emergency output from a 150W high bay at 8 metres typically delivers 3\u20134 lux on the floor; at 12 metres this drops below 2 lux, requiring either higher output percentage or additional luminaires.<\/p>\n\n

Maintained<\/td>\n
Emergency lamp energised continuously via normal driver; switches to battery on failure<\/td>\n
Corridors, stairwells, spaces where the escape route must always be lit<\/td>\n
Requires relay or electronic switchover rated for continuous duty; battery undergoes shallow cycling; specify LiFePO4 for better cycle life (500\u2013800 cycles vs. 300\u2013500 for standard Li-ion 18650)<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
For maintained operation with LED strips, confirm the emergency driver accepts the normal 24V DC or 48V DC feed and switches seamlessly; voltage drop in the strip itself (typically 0.5\u20131.0V per 5 metres on 2oz copper) must not push the LEDs below minimum forward voltage in either mode.<\/p>\n\n

High-temperature locations (above +40\u00b0C ambient inside the fitting) reduce Li-ion 18650 cycle life by 20\u201330% and increase thermal runaway risk. LiFePO4 cells tolerate +60\u00b0C but still require derated charge current above +45\u00b0C. Emergency twin spotlights mounted near roof level in unventilated factories often see +50\u00b0C; specify accordingly.<\/p>\n\n

Sample Approval and Mass Production Gate<\/h3>\n
Approve a physical sample before authorising mass production. Test the sample for: actual emergency output duration under full load (not just indicator LED operation); changeover time (less than 5 seconds for maintained, less than 0.5 seconds for non-maintained per EN 60598-2-22); and battery charge recovery after full discharge (24 hours to reach 80% capacity, 48 hours to 100% for most LiFePO4 packs). Record sample serial number and test date. Mass production should use identical cells from the same supplier batch; battery capacity can vary \u00b15% between cell batches, which at 3-hour duration margins can mean the difference between 175 minutes and 185 minutes of actual output.<\/p>\n\n
Freight and Customs Practicalities<\/h3>\n
For lithium batteries, UN 38.3 testing is mandatory for air and sea transport regardless of quantity. The test summary must show: test report number, cell or battery model, watt-hour rating (for Li-ion, Wh = nominal voltage \u00d7 Ah), and testing laboratory. IATA limits standalone lithium-ion batteries to 30% state of charge for air freight; batteries installed in equipment may ship at higher charge but require different packaging and labelling. Sea freight under IMDG Code is generally more economical for MOQ above 500 units and avoids the stringent charge-state limits, but transit time is 25\u201335 days to Europe or Africa versus 5\u20137 days by air.<\/p>\n
Carton packing for emergency drivers typically uses individual white boxes with foam inserts, 20\u201350 units per master carton, 10\u201315 cartons per plywood pallet for sea freight. Twin spotlights with large battery packs and reflector heads ship fewer per carton due to volume; confirm carton dimensions to calculate freight cost accurately. Each carton and pallet requires the lithium battery handling label, Class 9 dangerous goods label where applicable, and the conformity mark of the destination country if customs inspection occurs.<\/p>\n\n
Commissioning and First Annual Test<\/h3>\n
The ordering process does not end at delivery. Schedule commissioning within 14 days of installation: verify all luminaires switch to emergency correctly, record actual illuminance levels with a lux meter at floor level along escape routes, and log any fittings that fail to achieve the required 1 lux or 3 lux respectively. For self-test and DALI systems, programme the test schedule and verify fault reporting to the central panel. The first annual full-duration test, conducted 12 months after commissioning, confirms battery capacity has not degraded below the rated duration; replace any unit that falls below 80% of rated duration. Retain test records for the period required by local fire safety regulations\u2014typically 3 to 6 years.<\/p>\n
