Can emergency lights be switched?
Switchable emergency lighting enables you to use your emergency light like a normal light which you can switch on and off. 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.
Is it a legal requirement to test emergency lighting?
Not only is correctly functioning emergency lighting paramount for building fire safety and the protection of staff and building users, but emergency light maintenance is a legal requirement and failure to maintain and test these systems at least on an annual basis, leaves the duty holder liable for breaching the law.
What is the lux level for emergency lighting?

Can a key switch be used to interrupt primary lighting?
The key switch simply interrupts the live feed in the same way as any other switch would. However, for convenience, some sites do opt to have an emergency lighting test facility built in which does not interrupt primary lighting. This should be connected in one way only.
