switch them on when required. If you are fitting them in an area where
they could become annoying, e.g. boardroom where projectors are used,
this method would be used.
In offices I tend to go for combined emergency fittings with the
existing lighting in the room area. If this is not feasible then stand
alone non-maintained in the work area would suffice. Some people would
fit maintained but they don't always add to the quality of light when
working, e.g. mix of colours, brightness with existing lighting.
For the exit signs I would use maintained luminaires, in the event of
a fire they are instantly viewable.With non-maintained exit signs the
local lighting circuit would have to 'trip' off in order for them to
illuminate and this isn't always the case.
