How do photoluminescent signs & markings work?

The surface of the sign or marking contains photoluminescent pigments which absorb and store light energy from nearby light sources. Placed in complete darkness, the pigments give off a noticeable glow which can last for hours.

When electrical lighting fails during an emergency, the glow from EverGlow signs and markings helps occupants evacuate safely and quickly.

Are EverGlow signs & markings radioactive?

No. EverGlow signs & markings are photoluminescent which means they are powered by normal light sources. Some exit signs are what is called radioluminescent, which means they use ionizing (i.e. hazardous) radiation to illuminate the sign face. This ionizing radiation is usually provided by tritium. EverGlow does not now or nor has it ever sold radioluminescent signs.

What are the requirements for photoluminescent signs & markings?

For EverGlow signs & markings to meet code requirements, the building must provide the right kind of lighting, and in sufficient amounts to be able to charge the photoluminescent pigment. Please note that exit signs and egress path markings have different requirements.

We recommend either fluorescent lighting or LED lights with color temperatures of at least 4,000 Kelvin. We recommend at least 1 ft-candle of illumination on egress path markings, and 5 ft-candles on the exit signs. 5 ft-candles is roughly the amount of light needed to read a newspaper held at arm's length. Most offices have 20 - 50 ft-candles of illumination.

Lower color temperatures indicate a more reddish, gentle light, like the kind given off by incandescent light bulbs or certain types of LED's. Higher color temperatures indicate a harsh, bluish white like what we see from fluorescent light sources. Imagine how a piece of metal might glow in a furnace; as the temperature increases, the metal goes from a red glow to a more bluish color. For more detailed information, we recommend reading the Wikipedia article on color temperature.

Why is EverGlow TL300 Epoxy Coating divided into three containers (base, hardener & pigment)?

Separating the material increases the shelf life by keeping the components from clumping together. The user is also able to mix smaller quantities according to their own requirements.

Why does EverGlow not sell any plastic signs?

Aluminum signs are far superior to plastic signs in high temperature situations. Plastic exit signs have been known to melt during building fires. Aluminum signs are much more resistant to vandalism, which is a big problem in many buildings and especially in schools. EverGlow has focused on aluminum signs since its founding in 1997.
