This table shows the businesses providing emergency lighting and how their customers have rated them.
Emergency lighting is equipped with a battery pack that will start to work if the regular lamp fails through power outage. Emergency lighting is now an integral part of all public buildings, for obvious safety reasons.
Emergency lighting can be purely functional, or can be aesthetic ally pleasing too. Large decorative fittings, such as pendants , wall lights and some chandeliers can also be adapted to accommodate battery packs so that they will function as an emergency light should the electrical power fail.
