Emergency lighting

What is an emergency light fitting?

Emergency light fittings include a battery as a backup power source that is continuously charged. Emergency light fittings can tell when the power has failed and immediately switch to using the backup battery. The battery needs to power the light fitting for a minimum of 3 hours. To conserve power, the light output from the fitting is reduced, often to 10% of the normal light output.

What are the different types of emergency light fittings?

  • Maintained fitting

    Will operate as a normal light fitting and be controlled with all the other lights in the area, however when the power fails the maintained emergency fitting will continue to operate but, at a lower light level.
  • Non-maintained fitting

    Is normally switched off, with its batteries being continuously charged and a green LED showing fully charged. When the power fails then the fitting switches on using its battery supply. Non-maintained fittings are not part of the general lighting but are fittings such as emergency exit signs.

All JCC emergency light fittings can operate as a maintained and non-maintained light.

Lighting regulations

Open areas

The non-obstructed, quickest and safest escape route must be lit to a minimum of 1 lux during an emergency. If the open area is less than 60m2 and isn’t part of an escape route then emergency lighting isn’t required, however the exit doors for the emergency escape route must have signs or an emergency bulkhead light.

Escape route

An escape route such as a designated corridor must be unobstructed and lit to a minimum of 1 lux during an emergency.


Due to increased hazards, these areas need to be lit to a minimum of 2 lux during an emergency.
