How Do Photoluminescent Exit Signs Work?Photoluminescent exit signs do not require AC or electrical power. There is no battery or on/off switch. They require 54 lux or 5 foot candles of mercury vapor, metal halide, fluorescent lighting, and LED Lighting to charge them in which makes them illuminate. The term 54 lux or 5 foot candles is the required minimum amount of light to charge to insure a proper charge. The average office building has no problem meeting this requirement. In this charging process photons are excited and then brought back to a lower state. The photons then will be absorbed by a substance via electromagnetic radiation, which will take these to a high energy state and then moved to a state of lower energy. The photoluminescent exit sign will be fully charged in 60 minutes. They stay at there peak illuminate for a minium of 90 minutes however it can takes about 16-96 hours in darkness to fully discharge. Available in 50', 75' and industry leading 100' viewing distance
Are Photoluminscent Exit Signs Code Compliant?Yes photoluminescent exit signs or glow in the dark exit signs are UL 924 Listed. They meet codes and requirements of the NFPA 101 life safety (The Life Safety Code is the most widely used source for strategies to protect people based on building construction, protection, and occupancy features that minimize the effects of fire and related hazards.) Going Green with Photoluminescent Exit Signs Eco-friendly efforts are gaining ground in workplaces, representing both operating cost savings and consumer marketing points. Photoluminescent signs are an excellent way to stay in line with eco-friendly policies while still installing reliable safety precautions. The materials used in photoluminescent exit signs aren't hazardous to handle or dispose of like some gas-filled lighted signs and don't use electricity to operate. The unique glowing properties of photoluminescent paint allow companies to ensure the safety of their workers by providing emergency guidance without incurring the cost and disposal issues of mainstream signs. Even when the power fails and backup generators fail to fire up, photoluminescent signs will continue to light the way to safety. A great backup to keep in inventory in case an electrical sign malfunctions, they are also a good "secondary plan" to hang in alternate corridors or doorways that aren't often used. These glow in the dark products have a lot to offer for their modest price tag, and remain a go-to solution for building owners and compliance managers across the country.
