All buildings which have a large footfall or are reliant on artificial lighting are obliged to have emergency lighting installed as a legal requirement. This is usually so the people inside can find their way out in the event of an emergency. Hotels, theaters, cinemas, apartments, flats, warehousing, retail shops, pubs and restaurants are just some of the places you will find emergency lighting.

Stairwells and exit routes are the places which are most likely to be illuminated when the power is cut along with first aid areas, refuge points and fire equipment areas.
