How much does emergency lighting cost?
How much does emergency lighting cost? On average, the emergency lighting starts from somewhere around 130$ USD for almost more than 10 luminaires. The costs can easily exceed this range if additional PAT Testing and/or EICR are included.
What are photoluminescent exit signs?
Photoluminescent signs are so named because they are illuminated via the action of photoluminescence. Energy in the form of light (photons) is absorbed from their surroundings by the special coating and stored. This stored energy is then re-emitted as light, making the light “glow” when the building is dark.
