Emergency Lighting Requirements: EN 1838, 3-Hour Duration and What Importers Must Check

Emergency lighting is the one category where a paperwork mistake can void an entire shipment's usability: the fixture works, but the authority having jurisdiction rejects it. For EU-bound projects the framework is EN 1838 (the escape-lighting standard), the CPR framework requiring CE marking via EN 60598-2-22, and local building codes that almost universally converge on one number — 3 hours of battery autonomy. Here is what to check before you order.

The non-negotiables under EN 1838

Escape route lighting. Minimum 1 lux on the center line of escape routes, with a uniformity ratio (minimum/average) no worse than 1:40, and no more than half the route in shadow beyond the direct beam.
Open-area (anti-panic) lighting. For undefined escape paths across open floors: minimum 0.5 lux across the area, uniformity no worse than 1:40.
Duration. Batteries must support rated output for the specified duration — 1 hour or 3 hours. In practice, EU commercial projects specify 3 hours almost without exception; UK-derived codes and many Middle East tenders do the same.
Switchover time. Light must be restored within 5 seconds of mains failure on escape routes (0.5 s where movement risk is high, per risk assessment).

The product specs behind compliance

Spec on datasheet	What to verify
Rated duration (1h / 3h)	Ask for the battery discharge test report at rated lumen output, not just cell capacity in mAh
Output in emergency mode	Emergency lumen output is often ~10–30% of mains output — check it still meets the 1 lux route calc at your spacing
Battery chemistry	Ni-Cd and LiFePO4 dominate; LiFePO4 gives 4–5× cycle life for frequently-tested sites and high ambient temperatures
Self-test / auto-test	Function test monthly and rated-duration test periodically are code expectations; self-testing fittings save facility managers from manual checks
IP and impact rating	Escape hardware in industrial sites typically needs IP65 and IK08 minimum
Operating mode	Maintained (lamp always on, mandatory in some public spaces) vs non-maintained (only on failure) — confirm what the project spec demands

The importer's checklist

Demand the right certificates. CE under EN 60598-2-22 is the base; a CB report smooths acceptance in many markets. RoHS and REACH are standard asks for EU tenders.
Match the legend to the project. Exit signs with running-man legends are mandated in the EU; language variants (EXIT, Sortie, Salida) and arrow directions should be confirmed per shipment, not per range.
Check ambient temperature claims. Battery life collapses in heat; genuine 0–40 °C or wider ratings matter for Middle East and industrial plant rooms.
Think in systems, not SKUs. A project needs escape luminaires, exit legends, and often centrally monitored or addressable versions in larger buildings — a supplier who covers all three simplifies your BOM.

Frequently asked

Is 1-hour emergency duration ever acceptable?

Yes — some countries and occupancy types allow 1 hour, and residential blocks in several markets specify it. But if you stock one SKU for the EU, make it 3 hours; it satisfies the strictest common case and costs little more.

Can one fitting be both maintained and non-maintained?

Many of ours are switchable via wiring, which lets you consolidate SKUs across project types. Verify the mode on the dataplate when commissioning.

Do you supply test reports?

Yes — duration discharge reports, photometrics and EMC/LVD documentation ship with each order, and ENEC certification is available on selected emergency ranges.
