Emergency Lighting for Sale: Configurations Price and Supplier Guide

Emergency Lighting Buyer Guide

An IP65 emergency luminaire or emergency driver enclosure blocks dust ingress and withstands low-pressure water jets from any direction, making it suitable for covered outdoor walkways, car parks, food preparation areas and dusty plant rooms where lower ratings fail. For OEM customisation, the rating applies to the complete assembled product, not the bare driver module, so the host fixture housing, cable glands and diffuser must seal together to achieve the rating.

The right configuration depends on three factors: the host fixture’s internal volume and material, the emergency duration mandated by local regulations, and the conformity assessment required by the end-market inspector. IP65 housings typically add 15–25% to the base driver cost over an open-frame or IP20 unit, with complete OEM emergency luminaires in the USD 18–45 FOB range depending on battery chemistry and lumen output.

Matching the Emergency Module to the Host Fixture

IP65-rated emergency products fall into two categories: self-contained emergency luminaires with integrated batteries, and emergency conversion kits installed inside a host luminaire. For OEM applications, the critical dimension is the battery pack and inverter compartment. A typical 3-hour emergency kit for a 20W LED panel requires:

LiFePO4 packs tolerate 0°C to 45°C ambient operation, while NiCd extends to -20°C but carries heavier weight and shorter cycle life. The inverter module must mount where the sealed enclosure allows heat dissipation; exceeding 55°C internal temperature degrades both battery chemistries rapidly.

Regulatory Duration and Wiring Configuration by Market

EN 1838 and BS 5266-1 specify minimum 1-hour duration for escape lighting in most UK and EU premises, with 3 hours required for sleeping accommodation and healthcare. EN 60598-2-22 tests this at end-of-discharge voltage, not nominal, so a battery rated 3000mAh must deliver its final 10% of capacity above the inverter’s low-voltage cutoff. UL 924 and NFPA 101 in North America standardise 90 minutes. AS/NZS 2293 requires 90 minutes for Class C and D buildings, 2 hours for Class A and B.

Maintained wiring keeps the emergency lamp energised during normal operation via a changeover relay; non-maintained leaves it off until mains failure. DALI self-test facilities per EN 62034 automate the 30-second functional and annual duration tests, reducing maintenance labour but adding 8–12% to module cost. Manual test key versions suit small installations without building management systems.

What to Request from the Supplier

Buyers qualifying an OEM partner for IP65 emergency products should verify:

• Test reports for the complete assembly, not component certificates. IP65 validation requires enclosure testing with all cable entries and lenses fitted.
• Battery UN 38.3 test summary for lithium chemistries, mandatory for air freight and increasingly for sea freight under IMDG.
• Photometric data showing emergency output in lumens and distribution, not just percentage of normal output.
• Ambient temperature derating curves, particularly for Middle Eastern and African markets where enclosure internal temperatures exceed 50°C.

Lead times for custom IP65 housings with silk-screened legend or corporate colours run 35–45 days after mould confirmation, versus 15–20 days for standard enclosures. MOQ typically starts at 500 pieces for modified housings, 100 pieces for standard enclosures with customised inverter output current and battery duration.

Types and Configurations of Emergency Lighting

Full-Power Emergency Driver for LED High Bays

This class addresses the gap between normal industrial lighting and emergency escape illumination in high-ceiling spaces. A 150W LED high bay normally delivers 15,000–20,000 lm; in emergency mode the driver must sustain the full 150W or the space falls below EN 1838’s 10% of normal illuminance requirement for high-risk task areas. The inverter draws from a LiFePO4 battery pack typically configured at 25.6V with 6–12 Ah capacity, giving 3-hour runtime at 150W but weighing 8–15 kg. Luminaire OEMs buy these drivers to retrofit existing high bays without replacing the entire fixture. The limitation is physical: the battery pack requires a separate steel enclosure rated IK08 minimum, and the combined cost often exceeds that of a standalone emergency luminaire. Installers must verify the LED module’s forward voltage window (typically 180–260V DC at constant current) matches the inverter output; mismatch causes dimming or driver shutdown.

Reduced-Power Emergency Module for Panels and Tubes

The most common OEM configuration for ceiling-based iluminación de emergencia. The module delivers 10–30% of normal output—sufficient for a 600 × 600 mm LED panel to produce 150–400 lm in emergency mode, meeting BS 5266-1’s 1 lux minimum on the centre line of escape routes while reducing battery size to a 7.4V or 14.8V Li-ion 18650 pack at 2.2–5.2 Ah. Input voltage range is AC 85–265V for global compatibility; output window is typically 36–80V DC at 150–350 mA. M&E consultants specify these for open-plan offices where aesthetic consistency matters. The trade-off is coverage: at 10% output, spacing between luminaires must tighten to maintain continuous escape route illumination, increasing fitting density by 20–40% compared to full-power alternatives.

Maintained Emergency Exit Sign with LED Legend

Maintained wiring connects the sign to both a permanent unswitched live and a switched normal circuit. The legend illuminates continuously during occupancy; on mains failure, the internal changeover relay transfers to battery backup with no visible interruption. Battery packs are typically 3.2V LiFePO4 at 3000–6000 mAh, supporting 3-hour duration at 3–5W. Facility managers in the UK and Middle East favour maintained signs for compliance certainty—BS 5266-1 and local fire codes often mandate maintained operation in premises with sleeping accommodation or complex egress paths. The ongoing energy consumption (5W × 8760 hours/year ≈ 44 kWh annually per sign) is the unavoidable cost. Non-maintained alternatives exist but require separate normal lighting to illuminate the sign face during occupancy.

Non-Maintained Emergency Twin Spotlight

Twin spotlights activate only on mains failure, making them energy-efficient for intermittently occupied spaces. Each 3W LED head produces 200–300 lm; combined output of 400–600 lm suits open areas up to 50 m² with 3-metre mounting heights. The battery is typically NiCd 4.8V at 4000 mAh or LiFePO4 6.4V at 3000 mAh, with 24-hour recharge time after a full discharge. Electrical contractors install these in loading bays and external canopies where IP65 is essential and maintained operation would waste energy. The limitation is coverage uniformity: spot beams create hot spots and fall-off; achieving 1 lux uniformly across irregular floor plans may require more units than a distributed panel system. IK10 rating on the heads is advisable for vandal-prone locations.

Self-Test Emergency Driver with DALI Interface

EN 62034 defines the automatic test cycle: brief functional tests at intervals not exceeding 30 days, and duration tests annually or at 50% of rated battery life. A DALI-compatible driver reports results to the building management system, eliminating manual test key operations in large estates. Output is configurable—10%, 50%, or 100% of normal load—allowing the same SKU to serve different escape route categories. Battery chemistry is typically LiFePO4 for cycle life (500–800 full cycles) or Li-ion 18650 for compactness in shallow ceiling voids. Lighting designers specify these for schools and hospitals where maintenance access disrupts operations. The constraint is system dependency: without a commissioned DALI network, the auto-test data sits unreported; buyers must verify the supplier provides compatible DALI application controllers, not just the driver.

IP65 Bulkhead Emergency Luminaire

Sealed bulkheads with IP65 rating and IK08 impact resistance bridge indoor and outdoor iluminación de emergencia. The 5–15W LED array produces 300–1000 lm in emergency mode, with 90-minute or 3-hour duration from an internal 11.1V Li-ion pack at 4400 mAh or 14.8V LiFePO4 at 3300 mAh. The gasketed polycarbonate diffuser and die-cast aluminium body suit car parks, tunnels, and food processing areas where hose-down cleaning occurs. Procurement officers in Southeast Asia and Latin America favour this format for tropical humidity and dust. The critical supplier qualification is lithium battery transport documentation: UN 38.3 test summary, IATA Section II or Section IB labelling, and IMDG Code compliance for sea freight. Without these, customs clearance stalls and project schedules slip. Charge time is typically 24 hours from full discharge; ambient temperature range is –20°C to +50°C, though battery capacity degrades below 0°C.

Matching Configuration to Application and Supplier

Buyers shortlisting suppliers for custom OEM and ODM emergency lighting with IP65 rating should request three verification items: test reports to EN 60598-2-22 and EN 1838 (or UL 924 / AS/NZS 2293 for target markets), a battery pack specification sheet with cell manufacturer and chemistry, and a declaration of UN 38.3 transport test status for lithium-based products. The IP65 claim is meaningless without gasket material specification—EPDM degrades in hydrocarbon atmospheres, silicone survives. Hymark’s standard MOQ for OEM emergency configurations is 500 units with 4–6 week lead time; samples ship within 7 days against a refundable tooling deposit. FOB Shenzhen or CIF port terms are available; pallet packing is 24–36 units per carton stack depending on battery pack weight.

Specifications and How to Read Them

How to Read the Input Voltage and Frequency Line

The input voltage range tells you where the emergency driver will survive mains fluctuations without damage. AC 85-265V covers the global spread from 100V Japan to 240V UK; AC 220-240V assumes stable European mains and costs less because the internal power stage is not over-engineered for 277V North American commercial circuits. Frequency is almost always 50/60Hz dual-rated for export. If your luminaire OEM host fixture is rated 220-240V and you install a 100-277V emergency driver, the product works but you have paid for silicon you do not need.

How to Read the Driven Load and DC Output Window

“Driven load in watts” is the LED module power in normal mains operation. The DC output window—expressed as voltage range and current—must sit inside the LED module’s forward-voltage curve. A constant-current inverter output at 25-80V 350mA means the driver will adjust its voltage anywhere between 25V and 80V to hold 350mA steady. If your LED module needs 48V at 500mA, this driver is incompatible. Luminaire OEMs adding emergency versions to their own fixtures must match this window precisely; otherwise the emergency inverter either fails to strike the LEDs or overdrives them.

How to Read Emergency Output in Lumens and Percentage of Normal

EN 1838 and BS 5266-1 set minimum illuminance on escape routes: 1 lux on the centre line, 0.5 lux over the full width. The emergency output line tells you whether the product meets this after the designer has accounted for optic losses and mounting height. Entry-level 30% output suits open-plan offices with low ceilings. High-bay warehouses need either 100% full-power emergency output or a separate twin-spot arrangement. The percentage matters for maintained wiring designs: if the normal LED load is 50W and emergency output is 30%, the maintained circuit must still deliver full normal brightness from the mains, then drop to 15W equivalent on battery.

How to Read Emergency Duration

90 minutes satisfies UK BS 5266-1 and most of Europe under EN 1838. Two hours is common for healthcare and assembly occupancies under NFPA 101. Three hours appears in UK premises where phased evacuation or complex building geometry extends escape times. Duration is tested at the declared emergency output, not at zero load. A supplier quoting 3 hours at 3W but only 90 minutes at 10W is not being deceptive; the battery simply drains faster at higher load. Ask for the duration curve across the driver’s full output range.

How to Read Battery Chemistry Voltage and Capacity

NiCd 3.6V 1500mAh packs are the cheapest, tolerate deep discharge, but carry cadmium RoHS restrictions in Europe and suffer memory effect. Li-ion 18650 3.7V 2600mAh offers higher energy density but requires protection circuits against over-discharge; thermal runaway risk triggers UN 38.3 transport rules. LiFePO4 3.2V 3000mAh runs cooler, delivers 1500-2500 cycles, and is increasingly specified for high-temperature luminaires where +55°C ambient would degrade standard Li-ion. Capacity in mAh multiplied by voltage gives watt-hours: 3.2V × 3000mAh = 9.6Wh. At 4W emergency output with inverter losses, that yields roughly 2 hours, so high-specification builds parallel cells or boost voltage to reach 3 hours at higher loads.

How to Read Charge Time and Cycle Life

Charge time is the period from deep discharge back to full readiness; 24 hours for NiCd reflects trickle-charge chemistry, while 12 hours for LiFePO4 reflects higher acceptance current. Cycle life is the number of full discharge-recharge cycles before capacity falls below 80% of rated. For a self-tested system doing monthly function tests and annual duration tests, 500 cycles still covers 10-15 years. In high-cycling applications—frequent power outages in developing markets—LiFePO4 pays back its premium.

How to Read Test Facility

Manual test key: a button or switch simulating mains failure, requiring a maintenance walk-round. Auto self-test per EN 62034: the driver runs brief functional tests automatically and signals fault via a status LED. DALI self-test: reports over the DALI bus to a central monitoring system, required in large commercial installations where manual testing is impractical. DALI emergency devices use DALI Type 0 or Type 1 commands; verify the supplier’s DALI implementation is tested against IEC 62386-202, not merely the general 101/102/103 parts.

How to Read Maintained Versus Non-Maintained Wiring

Non-maintained: the emergency fitting is dark in normal operation, illuminates only on mains failure. Wiring is simplest: permanent live, neutral, switched live optional for indicator. Maintained: the fitting is lit in normal operation via a changeover relay, then switches to inverter output on failure. The relay coil is energised from mains; when mains drops, the relay de-energises and contacts switch to battery. Maintained wiring requires a switched live that remains energised during normal hours, plus the permanent feed to charge the battery. Some drivers offer maintained/non-maintained selection by wiring terminal or DIP switch; others are dedicated. OEMs must specify this at order because the PCB layout differs.

How to Read IP and IK Rating

IP65 means dust-tight and protected against low-pressure water jets from any direction. For the search phrase “IP rating 65,” this is the threshold for outdoor canopies, food processing, and hosed industrial areas. The first digit 6 is absolute for dust; the second digit 5 is not submersible (IP67) but resists washdown. IK07 (2 joules) or IK08 (5 joules) covers impact from tools or debris in plant rooms. Entry-level IP20 is indoor only. If your host fixture is IP65 but the emergency driver is IP20 internal, the combination is IP20; the weakest link governs. Remote-head emergency twin spotlights must carry the full IP rating on both the luminaire head and the battery enclosure.

How to Read Ambient Temperature Range

Battery chemistry limits the range. NiCd performs poorly below 0°C; Li-ion below -10°C risks plating and short-circuit. LiFePO4 tolerates -20°C but with reduced capacity. At the high end, +45°C is standard; +60°C requires derated charge current or the battery life collapses. Industrial LED high bays in foundries or Middle Eastern roof spaces often see +55°C ambient; specify the high-temperature variant or accept 3-year battery replacement cycles.

How to Read Dimensions Mounting and Weight

Internal driver boxes fit inside the host fixture cavity; verify length against luminaire housing depth. Remote enclosures mount on cable tray or wall within 3 metres of the luminaire (per BS 5266-1 wiring distance guidance for twin-spot heads). Weight matters for shipping: a 280×80×45 mm LiFePO4 enclosure weighs approximately 1.2 kg versus 0.6 kg for NiCd. For air-freight sample orders, this affects courier cost more than unit price.

Trade Terms and Export Practicalities

FOB (Free On Board): seller delivers goods onto the vessel at named port; buyer pays ocean freight and insurance. Use this when you have freight forwarders in Shenzhen or Ningbo.

CIF (Cost Insurance Freight): seller arranges ocean freight and marine insurance to destination port; buyer clears customs and handles inland delivery. Adds 8-15% to EXW factory price for a 20-foot container of emergency luminaires.

CFR (Cost and Freight): seller pays freight, buyer arranges insurance. Rare in lighting; most buyers prefer CIF or FOB.

EXW (Ex Works): buyer collects from factory. Lowest quoted price, but you handle export clearance, truck to port, and all documentation. Only practical if you maintain China logistics staff.

L/C (Letter of Credit): bank guarantees payment against presentation of compliant documents. Protects both parties on first orders over $50,000; costs 0.5-2% in bank fees and adds 5-10 days to lead time.

T/T (Telegraphic Transfer): wire payment, typically 30% deposit, 70% before shipment. Standard for repeat orders under established terms.

HS Code: 9405.10 for battery-powered emergency lighting; 9405.40 for LED luminaires with integrated emergency function. Customs classification determines duty rate and whether lithium battery declarations are triggered.

CE and UKCA Marking: CE indicates conformity with EU directives; UKCA is the post-Brexit UK equivalent. The supplier must provide a Declaration of Conformity and technical file. Do not accept a CE mark on battery products without verifying the battery and inverter are included in the EMC and LVD assessment.

UN 38.3 Battery Test Report: mandatory for lithium battery air and sea transport. Tests include altitude simulation, thermal cycling, vibration, shock, external short circuit, crush, and forced discharge. Ask for the UN 38.3 test summary in the supplier’s name, not a cell manufacturer’s generic report. Without this, freight forwarders will refuse booking.

Packing List and Certificate of Origin: packing list details carton count, gross/net weight, and HS code per line. Certificate of Origin (Form A or CO) may be required for duty preference under bilateral agreements; verify with your customs broker whether China-origin goods qualify for reduced tariff in your market.

Supplier Qualification Checklist

Before shortlisting, request: the Declaration of Conformity scope (does it cover the exact model and battery combination?), the UN 38.3 test summary for lithium variants, photometric test report to EN 1838 showing spacing data for your ceiling height, and a sample wired into your host fixture for thermal and photometric verification. Lead time for custom OEM builds with your logo and silkscreen runs 35-45 days after artwork approval; ODM projects with modified enclosure or output characteristics run 60-90 days. MOQ typically 500 units for OEM, 200 units for standard models with customised label. Samples ship within 5-7 days against courier account or prepaid freight.

Emergency Lighting Price and What Drives It

These bands assume factory-direct FOB Shenzhen or Ningbo for 500–2,000 piece MOQ, single-colour carton packing, and lithium-based battery chemistry. NiCd reduces cell cost by 30–40 % but shrinks cycle life from 500–800 to 200–300 cycles and lengthens charge time from 4–6 h to 16–24 h.

What Drives the Factory Price

Battery pack y third-party approval are normally the two largest line items on an emergency lighting BOM. Together they account for 35–50 % of ex-works cost on a mid-range IP65 bulkhead.

Cell-level cost. A LiFePO4 3.2V 1500mAh cell (4.8Wh) costs roughly 1.80–2.50 USD in 1,000-off OEM volumes. A 3-cell 9.6V 1500mAh pack with PCM, NTC thermistor and 18AWG leads adds 7.00–11.00 USD. Li-ion 18650 3.7V 2600mAh cells (9.6Wh) run slightly cheaper at 1.50–2.20 USD per cell but carry stricter transport rules and shorter cycle life (300–500 vs 500–800). NiCd 3.6V 1200mAh is 1.00–1.40 USD per cell, yet its 16–24 h charge time and memory-effect degradation make it a false economy for sites running monthly functional tests under EN 62034 or BS 5266-1.

Driver and inverter electronics. A constant-current emergency inverter with changeover relay, output 9–42V DC at 150–350mA, costs 3.50–6.50 USD in volume. Add 2.00–4.00 USD for a self-test microcontroller or 4.00–8.00 USD for DALI-2 emergency compatibility. The output window must match the host fixture’s LED forward-voltage curve; a mismatch here is the most common cause of sub-spec emergency lumen output.

LED package. Emergency-only products use modest LED counts—8–24 pcs 2835 or 3030, 0.5W each—costing 1.50–3.50 USD. Maintained luminaires reuse the main LED array, so the emergency driver cost is additive but LED cost is not.

Enclosure and sealing. An IP65 polycarbonate housing with gasket, diffuser and stainless-steel clips costs 3.50–6.00 USD. Die-cast aluminium with tempered glass and IK08 rating pushes this to 8.00–14.00 USD. The “65” in your search phrase means dust-tight and protected against low-pressure water jets; achieving this with maintained wiring glands and test-key access points requires moulding complexity that budget housings omit.

Test and certification amortisation. EN 60598-2-22 and EN 1838 testing at an accredited lab runs 8,000–15,000 USD per product family. Spread across a 2,000-piece first order, this is 4.00–7.50 USD per unit. A supplier who skips pre-production validation and offers “CE available on request” is externalising this risk to you.

Assembly, packing and logistics. Direct labour in Guangdong is 0.80–1.50 USD per unit for final assembly and 120-second functional burn-in. Export carton (double-wall, 12 units) and pallet add 0.60–1.20 USD per piece. Inland freight to Yantian or Ningbo port is 0.30–0.80 USD. Sea freight to UK/EU ports is 0.40–0.90 USD per unit at 40′ FCL; air freight is 3.00–6.00 USD but prohibited for standalone lithium cells unless UN 38.3 certified and shipped at 30 % SOC under IATA PI 965 Section IB. IMDG sea containers require lithium marking, Class 9 labels and emergency response documentation.

Landed cost stack. On a 22 USD FOB IP65 bulkhead, typical additions are: marine insurance 0.50 USD, EU duty 2.20–3.30 USD (HS 9405.10 at 2.7–4.7 % depending on EU tariff schedule), VAT 20 % on CIF+duty value, and customs clearance 150–300 USD per consignment (amortised 0.30–0.60 USD at 500 pcs). UK landed cost ends at roughly 28–34 USD before distributor margin.

Why the Cheapest Quote Is Cheaper

A 4.50 USD exit sign versus a 7.00 USD equivalent from the same factory usually reflects one or more of these:

• Smaller cell: 600mAh NiCd instead of 1500mAh LiFePO4, yielding 60–70 min actual runtime instead of 90 min at end of discharge.
• Reduced emergency output: 5 % of normal instead of 10 %, or 50 lm instead of 120 lm, failing EN 1838 minimum illuminance requirements for escape routes (1 lux on centre line, 0.5 lux on perimeter).
• Untested design: No thermal cycling validation, no 70 °C ambient soak, no EMC pre-scan. The product passes initial assembly but fails in first-year service.
• Omitted relay or diode: Direct-drive inverter without changeover relay, so the fixture cannot switch cleanly between mains and emergency modes in a maintained installation.

Five-Year Running Cost Comparison

The mid-range unit nearly closes the gap on initial cost through lower failure rates, but the intelligent unit with automated testing breaks even by year three through labour savings alone. This assumes a UK/EU labour rate; in Southeast Asia or Africa where technician time is cheaper, the manual-test budget option retains economic logic for longer.

Qualifying the Supplier for OEM and ODM

For buyers adding emergency versions to existing fixtures, verify these points before tooling payment:

• Battery form factor: Can the supplier provide a 14.8V 2200mAh Li-ion pack in a 120 × 30 × 20 mm envelope to fit your linear housing? Or only standard 18650 sleds?
• Inverter output mapping: Will they programme the CC window to your LED string voltage—say 36V at 240mA for a 48W panel—rather than forcing a 9–21V default?
• IP65 maintained gland: Is the cable entry dual-rated for maintained live, switched live and neutral, with strain relief tested to EN 60598-2-22 clause 22.17?
• Documentation package: Can they provide UN 38.3 test summaries for the cell, IEC 62133 reports for the pack, and a technical file structure for your own CE/UKCA declaration? Do not accept “certificates can be arranged” as an answer; ask for report numbers and issuing bodies you can verify.

Hymark’s standard MOQ for ODM emergency driver programmes is 1,000 units with 35–45 day lead time after EVT sample approval. Samples with customised output windows ship within 7–10 working days against a refundable tooling deposit.

Industry Applications for Emergency Lighting

Commercial Offices and Fit-Outs

Open-plan offices with 600x600mm suspended ceilings typically use 30-40W LED panels producing 3,000-4,000 lumens. The emergency driver must deliver roughly 450-600 lumens, or 10-15% of normal output, for 90 minutes to satisfy EN 1838 escape-route lighting. A non-maintained configuration is standard: the emergency module sits idle during mains presence, switching on via changeover relay when power fails. Self-test circuitry per EN 62034 automates the 30-second functional test and annual duration test, cutting facility management costs in buildings with 500+ luminaires. Ask the supplier to confirm the driver fits within the 75mm ceiling void common to modular tile systems; some 3-hour kits exceed this depth.

Hospitals and Clinics

Healthcare premises in the UK fall under BS 5266-1 Category H, mandating 3-hour duration for all escape lighting and often requiring maintained operation in critical care areas. A maintained LED downlight running at 20-100% of normal output during mains failure needs a driver capable of continuous DC output without flicker during changeover. LiFePO4 chemistry at 3.2V 3000mAh provides the energy density for 5W maintained output across 180 minutes, with roughly 500-800 cycles to 80% capacity. The battery pack should be housed separately from the LED module in thermally managed enclosures, as ward ceilings often reach 35°C in summer. Verify the supplier can supply maintained wiring diagrams showing connection to unswitched permanent live, switched live, and neutral.

Warehouses and Logistics Centres

Racking aisles at 12m mounting height need emergency output that reaches the floor at usable levels. A 150W LED high bay producing 18,000 lumens normally requires 15W emergency output (1,800 lumens, 10%) to achieve the 1 lux minimum at ground level per EN 1838. The driver input at AC 100-277V covers both European 230V and Middle Eastern 277V distribution. LiFePO4 3.2V 6000mAh packs, typically 2P2S configuration, sustain 10-20W loads for 3 hours. IP65 sealing prevents dust ingress from forklift traffic; IK08 handles accidental pole contact. Charge time from full discharge is 20-24 hours, so specify chargers rated for the duty cycle if your site experiences frequent brief outages.

Car Parks and Stairwells

Multi-storey car parks combine moisture, salt aerosol in coastal locations, and physical abuse. IP65 is the practical minimum for surface-mounted bulkheads; IK10 for polycarbonate diffusers resists 20J impact. A 3-hour NiCd 3.6V 1500mAh solution costs less upfront than LiFePO4 but delivers only 300-400 cycles and requires replacement every 3-4 years in daily-test regimes. The 2-hour duration accepted in some jurisdictions (check local amendments to EN 60598-2-22) allows smaller battery packs and faster charge: 16 hours versus 24 hours for 3-hour kits. Twin-spot luminaires with adjustable heads suit open-deck ramps where wall mounting is impractical; specify the beam angle (typically 30° or 60°) to match your column spacing.

Hotels and Residential Common Areas

Fire-rated downlights in hotel corridors often have 50-70mm ceiling voids, constraining emergency driver dimensions. A 3W emergency output at 15% of a 20W decorative fitting provides 300 lumens, sufficient for corridor escape routes under EN 1838. Maintained wiring is frequently specified to keep corridors lit during generator startup delays. NiCd 3.6V 1500mAh remains common in this sector due to lower first cost, but LiFePO4 3.2V 1500mAh at 20% weight reduction eases installation in plasterboard ceilings. The supplier should demonstrate compatibility with 0-10V or DALI dimming circuits if your design uses presence detection; some emergency drivers bypass dimming and restore full output on mains failure.

Industrial Plants

Process industries often specify 3-hour duration not for escape alone but for safe plant shutdown. The emergency driver must tolerate voltage dips and swells on site distribution networks: AC 85-265V or 100-277V input range is essential. Ambient temperatures in steel or glass plants exceed +40°C; LiFePO4 chemistry maintains cycle life better than Li-ion 18650 above 45°C, though capacity derates above 60°C. A 10-15W emergency output from a 100-150W LED high bay demands careful thermal coupling between driver and battery; request the supplier’s derating curve showing output versus ambient. IP65 with gasketed cable entries prevents corrosive atmosphere ingress; specify stainless steel brackets in chemical plant environments.

Ordering and Importing Step by Step

The three mistakes that most often leave a delivered batch of emergency lighting unusable are:

Host Fixture Audit Before Enquiry

Record these values from the existing luminaire or from the OEM’s datasheet. The emergency inverter must sit electrically between the battery and the LED module, so its output window must overlap the LED’s operating point.

Example match: A 150W LED high bay with Vf 200V–260V at 700 mA needs an emergency driver with output window roughly 180V–280V DC at 700 mA constant current, driving a 50W LED load in emergency mode (33% of normal) from a LiFePO4 12.8V 4500mAh battery pack.

Duration Emergency Output and Percentage

The emergency output is expressed as a percentage of normal luminous flux and as an absolute lumen value. The local code sets the minimum.

Practical numbers to agree:

• Emergency output as % of normal: 5%, 10%, 20%, 33%, 50%, 100% (full output emergency drivers exist for high-risk task areas)
• Emergency output in lumens: if normal output is 10,000 lm, 10% = 1,000 lm emergency
• Duration: 90 minutes, 120 minutes, 180 minutes (3 hours)
• Battery chemistry and capacity to achieve this: LiFePO4 3.2V 3000mAh per cell, 4S2P 12.8V 6000mAh for 3 hours at 20W; or Li-ion 18650 3.7V 2600mAh, 3S3P 11.1V 7800mAh for longer durations

Maintained Versus Non-Maintained Wiring

Specify which at enquiry. A maintained unit costs more and needs more terminals. Do not assume the supplier knows your wiring method.

Test Facility Selection

Trade-off: Self-test and DALI add 15–25% to driver cost and draw standby power (typically 1–3W) that slightly reduces battery cycle life. Manual test is cheaper but requires a logbook and disciplined staff.

Mains Voltage and Frequency by Destination

Specify the input voltage range on the driver label. A 220V–240V driver is cheaper but unusable on 110V sites. A 100V–277V driver covers all markets but costs 10–15% more.

Conformity Marks and Test Reports to Request

The supplier should provide documentation that matches the destination’s customs and inspection expectations. Do not accept vague claims.

Critical: For lithium battery shipments, request UN 38.3 test summary reports for the exact cell and pack configuration. Customs in many jurisdictions now flag batteries without this.

IP Rating and Ambient Temperature for Mounting Position

IP65 in your search phrase is a common threshold for car parks, warehouses, and food processing. Confirm whether the entire fitting including battery compartment meets IP65, or only the LED head. Battery compartments often need separate sealing.

Frequently Asked Questions About Emergency Lighting

Matching the Product to Your Fixture and Market

Q: What is the minimum order quantity and how do I confirm the emergency driver suits my host luminaire?

MOQ is 100 units for branded Hymark emergency modules, 500 units for OEM private-label versions. Match the driver to your fixture by checking three parameters: the AC input range of the driver against your luminaire’s supply (typically 220-240V or 100-277V), the DC output window against your LED module’s forward voltage, and the maximum wattage the emergency inverter can sustain versus your fixture’s normal load. Request a dimensional drawing to verify physical fit inside the host housing.

Q: What emergency duration and output options are available, and how do they relate to my fixture’s normal output?

Standard durations are 90 minutes, 2 hours, and 3 hours per EN 1838 and BS 5266-1. Emergency output is specified as a percentage of normal output—commonly 10%, 20%, 50%, or 100%—or as absolute lumens, for example 500 lm or 1000 lm emergency from a 4000 lm normal-output LED panel. A 100% output emergency driver for a 50W LED high bay requires a LiFePO4 12.8V 6000mAh pack delivering roughly 50W for 90 minutes. Lower percentages permit smaller batteries and lower cost.

Q: What is the difference between maintained and non-maintained wiring, and which should I specify?

Non-maintained wiring powers the emergency LEDs only during mains failure; the unit contains a changeover relay that isolates the emergency LED string from the normal driver. Maintained wiring allows the emergency LEDs to operate during normal conditions as well, either continuously or switched via a separate live feed. Specify maintained for escape routes requiring constant illumination per local code; specify non-maintained for standby-only applications where normal lighting is always present during occupancy.

Test Facilities and Battery Technology

Q: What self-test and remote-test options are available, and what do the standards require?

Manual test via key switch is standard. Automatic self-test per EN 62034 performs brief functional tests at intervals and full-duration tests annually, reporting via LED status indicator. DALI-2 test facility enables remote monitoring and scheduling via building management systems. EN 62034 specifies test intervals and fault indication requirements. Ask your supplier to confirm the firmware version and whether the DALI implementation is certified for interoperability with your BMS platform.

Q: What battery chemistry is used, what is the replacement interval, and what are the trade-offs?

LiFePO4 3.2V cells in series configurations (6.4V, 12.8V, 25.6V) offer 2000 to 3500 cycles, 4 to 6 hour charge time, and 5 to 7 year service life. Li-ion 18650 3.7V packs provide higher energy density but 500 to 800 cycles and 3 to 4 year life. NiCd 3.6V to 9.6V packs tolerate -20°C to +50°C ambient but require annual replacement in heavy-cycling applications and face disposal restrictions in EU markets. LiFePO4 adds 15 to 25% to unit cost versus NiCd.

Logistics Documentation and Supplier Qualification

Q: What lead time, sample policy, and payment terms apply for export orders?

Standard lead time is 25 to 30 days after order confirmation and deposit receipt. Samples of standard models ship within 5 to 7 working days against payment; sample cost is credited against first production order above 500 units. Payment terms are 30% deposit, 70% against copy of bill of lading for orders under USD 50,000; letters of credit or 60/90-day terms for established accounts above USD 100,000 annual volume. OEM orders with custom silkscreen or packaging add 7 to 10 days.

Q: Which test reports and conformity marks can be supplied for my destination market, and what should I verify?

For UK and EU markets, ask for EN 60598-2-22 and EN 1838 test reports, plus EN 62034 for self-test models. The CE mark is the supplier’s declaration; verify the test reports cover your specific model variant and are issued by an accredited laboratory. For the Middle East, request SASO or ECAS conformity documentation. For Southeast Asia, check whether CB test certificates are accepted or if in-country testing is mandatory. For Australia, AS/NZS 2293.3 compliance is required. Never accept a certificate for a different product family or voltage variant.

Q: How do lithium batteries affect shipping mode and required documents, and what are the carton specifications?

LiFePO4 and Li-ion packs are UN 38.3 classified Class 9 dangerous goods. Sea freight (IMDG) requires MSDS, UN 38.3 test summary, and dangerous goods declaration; air freight (IATA PI 966 Section II or PI 967) limits state-of-charge to 30% and requires shipper’s declaration. Cartons are 10 units per inner box, 4 inner boxes per export carton, 40 units total, gross weight 18 to 22 kg depending on battery capacity. Pallet configuration is 24 cartons per 1200 × 1000 mm IPPC-treated wooden pallet. NiCd packs ship as environmentally hazardous but with fewer modal restrictions.

OEM Support and After-Sales

Q: What OEM branding packaging options and installation support are provided?

OEM silkscreen on the driver housing and custom carton artwork are available at 500 units MOQ; packaging design support is free, print plate charges apply at USD 180 per colour. Warranty is 3 years on electronics, 2 years on LiFePO4 batteries, 1 year on Li-ion and NiCd packs. Spare parts availability is guaranteed for 5 years from last production date. Installation manuals are supplied in English; translated versions for Arabic, Spanish, or Portuguese require 10 working days and minimum 300 unit order. Commissioning support is remote via video call; on-site technician deployment is quoted per diem plus travel.

Important Notice

Sourcing Emergency Lighting from Hymark

Why Hymark Matches OEM and Project Requirements

Hymark’s emergency driver programme is built on the 2017 shift to LED emergency technology at JIALINGHANG ELECTRONIC CO., LTD. The range spans self-contained emergency luminaires, exit signs, twin spotlights and LED emergency drivers for retrofit into OEM fixtures. Input voltage covers AC 85-265V or 100-277V depending on SKU. Emergency output is configurable at 3W, 5W, 8W or full power, with durations selectable at 90 minutes, 2 hours or 3 hours. Battery options include LiFePO4 3.2V packs at 1500mAh to 3000mAh, Li-ion 18650 3.7V 2000mAh to 2600mAh, or NiCd 3.6V 1200mAh to 1800mAh. LiFePO4 delivers roughly 800 to 1500 cycles versus 500 to 800 for standard Li-ion and 300 to 500 for NiCd, but carries higher cell cost and stricter UN 38.3 transport documentation for air freight.

IP65 enclosures are standard on surface-mounted emergency luminaires and available on driver housings for dusty or hose-down environments. The constant current inverter output window is typically DC 9-42V at 150mA to 700mA, matched to the host LED module voltage-forward curve. Changeover relay enables maintained wiring; non-maintained wiring bypasses the relay for simpler installation.

What to Verify Before Placing an Order

Buyers should request third-party test reports for EN 60598-2-22, EN 1838 and EN 62034 compliance for European markets; BS 5266-1 for UK projects; UL 924 for North America; or AS/NZS 2293 for Australia and New Zealand. Ask specifically whether the supplier holds current test certificates or whether they engineer to the standard and rely on the buyer to arrange local certification. Hymark co-designs and engineers products in-house through its strategic partnership with manufacturing facilities operating since 2013, managing R&D, product design and global distribution directly. This structure supports OEM branding, custom duration settings, maintained or non-maintained wiring, self-test or DALI test facility integration, and selectable battery chemistry.
