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

NON ELECTRICAL EXIT SIGNS

Non powered exit signs do not require electricity. There are two types, both of which glow in the dark. All models listed on our website are UL 924 Listed for the United States and Canada. They can be used in place of traditional electrical exit signs and are guaranteed to be building and fire code compliant.

The first type of non illuminated sign, photoluminescent, absorbs light and then glows in dark environments, such is the case when AC power is lost and a building's lighting system fails. Photoluminescent exit signs are suitable for indoor commercial applications where the lights are normally on when the building is occupied. They are popular for apartments, offices, schools, hospitals and other similar applications.

The second type, self-luminous, use a glowing form of hydrogen gas, known as tritium, to constantly illuminate. There is absolutely no power source needed (including light) for self-luminous exit signs to operate. Self-luminous exit signs are completely universal, they can be placed indoors or outdoors. In the case of applications where light is not available all the time or the sign is being placed outdoors, choose a self-luminous exit sign.

WHAT COLOR EXIT SIGN SHOULD I USE?

Exit sign color depends on the municipality. Check with your local fire marshal. He or she will let you know the correct color for your area.

WHAT ARE THE LIGHTING REQUIREMENTS FOR AN EXIT SIGN?

Exit signs must be illuminated to a surface value of at least five foot-candles. A reliable light source must illuminate them, and the exit signs’ colors must be easy to distinguish.

WHERE SHOULD EXIT SIGNS BE SITUATED?

Exit signs should be placed where the direction to the nearest exit sign isn’t clear, or where a local fire marshal has directed them to be placed.
