Switchable emergency lighting enables you to use your emergency light like a normal light which you can switch on and off. Most maintained emergency lights can be used in this way, giving you the flexibility to either leave the emergency light on permanently or to use it as you would any other light. A switchable emergency light will still come on in the event of a power failure even if it is switched off at the light switch as it will automatically take the power from the back-up battery. Where you have a switchable emergency light you can use one light for normal day to day purposes without having to have a separate emergency light that will illuminate your exit route.
Some maintained emergency lights can also be used as non-maintained lights. It is important to know that the switchable function can only be used when the emergency light is set to maintained operation.
The Meled is available in a choice of three power outputs to suit almost any need, and their LED technology provides brighter, clearer light compared to fluorescent emergency lights.
The Leah IP65 round emergency light with LEDs has greatly reduced power consumption while providing clearer, brighter lighting.
With a fully recessed design, the ceiling mountable Calabor LED emergency bulkhead provides a stylish lighting solution with a greater lamp lifetime and reduced power consumption compared to standard units.
With either maintained or non-maintained operation available the energy saving LEDs provide the Arc emergency bulkhead light with an approximate lifespan of over 54,000 hours.
This low-profile circular IP65 rated Mezzina emergency bulkhead light utilises LED technology to greatly reduce power consumption while providing a clearer, brighter light.
Available in 2 lengths and 4 power outputs the Ipstones emergency strip lights are supplied in either maintained or non-maintained operation, suitable for various lighting applications.

With the same features as the 8W Calabor emergency lighting bulkhead light with self-test, this version also gives you high performance energy saving LEDs with an approximate lamp life of 50,000 hours.
Maintained Operation
When in maintained operation the lamp of an emergency luminaire stays on constantly at all times and stays lit for the minimum emergency duration after a mains failure. Maintained lights can be wired to a light switch to be used as normal room lighting and will function as emergency lighting during a mains power failure even when switched off.
Non-Maintained Operation
When in non-maintained operation the lamp of an emergency luminaire will only light in the event of a mains failure and will stay lit for the minimum emergency duration required.
Please Note: Maintained units are capable of being wired to enable non-maintained operation.
Mains Operation
Mains operated units are designed to be wired into a local power circuit for general lighting and do not have emergency functionality. They are available for purchase to facilitate installation of the same style fittings throughout an entire premises.
Slave Units
Slave fittings have no internal backup battery and must be wired into a dedicated power circuit. In the event of a power failure, slave units are powered by a bank of larger batteries centrally located within the premises. The operation of the slave unit (i.e. maintained/non-maintained) is reliant on the operation of the backup battery system.
An emergency light unit that can be wired to a switch, allowing it to be turned on or off for regular use (switching the unit between maintained and non-maintained operation). In the event of a mains power / circuit failure the lamp on the unit will be powered by its back-up battery.
When in emergency operation the light output of the emergency light will drop to approximately 10% of its normal light output. This ensures that the back-up battery will power the lamp for the required duration (3 hours). The stated light output (in Lumens) in the product description is the light output in emergency operation.
