When looking for the emergency lighting fitting you require, you are likely to come across the terms 'maintained' and 'non-maintained'. These phrases are terminology usually associated with emergency lighting products, but what is the difference?

Maintained fittings are ones which can be operated with a lighting controller (such as a switch) and can be left permanently on or can just operate when there is a power cut.
