What's the difference between maintained and non-maintained emergency lights? (May be a stupid question!)

The non-maintained lights will only come on in the event of a power failure.
The maintained lights you can also use as normal. icon_smile.gif

Aaah!

Makes sense, although using the term 'maintained' for it doesn't!!

Sustained lights have two lamps, basically a normal lamp and a non-maintained emergency light.
The normal lamp can be switched, very similar concept to a maintained unit but the maintained unit only having the single lamp for both duties.

How many lamps in them?
Probably maintained, with a wire loop between L and Ls.
That is assuming they are self contained (have their own battery pack in them).
