What is Sustained Emergency Luminaire?
What is Switchable Maintained Lighting?
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.
