Before Installing Glow in the dark signs

Glow in the dark exit signs and egress systems are fast becoming a preferred option in fire safety for building owners. This technology uses phosphor offers the lowest maintenance option on the exit sign market today, as well as the most cost-effective.

Like anything, you need to do your research before making the purchase. Glow in the dark exit signs also referred to as photoluminescent exit signs, are generally an excellent option for building owners because of their multitude of benefits. Jessup Manufacturing, a leader in photoluminescent films and sheets, is offering some insight into how the technology works, what the real benefits include, and how to make sure the product you choose will meet building fire safety codes.

The Technology Behind Glow in the Dark Exit Signs

We will try not to get overly scientific here. The technology powering photoluminescent exit signs is actually pretty simple. They use something called long persistent phosphor (LPP) that acts like a sponge. LPP absorbs surrounding light energy and holds it in until it’s needed- usually in the case of a power outage or in the evening hours when lights are out. In many cases, LPP will release the illumination well over 18 hours.

This technology isn’t like other glow in the dark technologies of the past. Unlike tritium, it is safe for the environment and can be recycled when it needs to be replaced (which won’t be for a long time, the Jessup GloBrite line lasts up to 25 years!).

Eco-Friendly + Energy Savings

Glow in the dark exit signs and egress systems bring your building a double whammy of excellence. Offering massive energy savings compared to their incandescent and LED exit sign counterparts, these are the most eco-friendly option. Also, because they do not require battery backup you will eliminate the costs of testing.

If you are in the process of building new construction you can also add to the savings by choosing photoluminescent exit signs. Developers can save an average of $450 per sign location because they will be eliminating the infrastructure associated with electrical exit signs (think of all the wiring, junction boxes, circuit breakers, plus all the electrical labor savings!). Builders can also get points towards LEED certification. 

Glow in the Dark Exit Signs up to Code

When it comes to fire safety signage in your building you need to make sure it is up to code for numerous regulating authorities. NFPA, IBC, and OSHA are three of the top authorities, along with your state and local jurisdictions (always consult with your fire marshal when it comes to the most up to date information).

Photoluminescent exit signs need to be listed UL 924. This is non-negotiable in any city or state in the United States. Some additional important points include (this is not a complete listing) Other important points to note include:

• Photoluminescent fire safety products have to “charge” appropriate levels of lighting. NFPA 101 specifies in 7.10.7.2 the illumination needs to be a reliable light source, determined by the jurisdiction having authority, and the levels of illumination on the face of the photoluminescent sign need to be in accordance with its listing.
• Photoluminescent fire safety products have to work for 90 minutes. Exit-sign illumination must be at least 90 minutes once power is lost. This 90-minute requirement also applies to egress markers according to the IBC (1025.4).

OSHA approves the use of photoluminscent exit signs and egress systems if they meet basic requirements. This includes the exit sign being illuminated to a surface value of at least five foot-candles (54 lux) by a reliable light source and distinctive in color. Self-luminous or electroluminescent signs that have a minimum luminance surface value of at least .06 foot-lamberts (0.21 cd/m2) are permitted. OSHA also requires that each exit sign must have the word "Exit" not less than six inches (15.2 cm) high, with the principal strokes of the letters in the word "Exit" not less than three-fourths of an inch (1.9 cm) wide.
