STAIR NUMBER SIGN - GLOW IN DARK
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. We carry in stock all types of Photoluminescent signs which include glow in the dark stair number signs.
