Light charging – 54 lux light requirement at installation location needed to maintain the “charge” of the photoluminescent pigment (light can be from manmade or natural sources), so these are not suitable for dark locations.Low cost – UL Listed exit signs starting in the $40 range, so these offer the most value when installation costs are factored in.No need for batteries, bulbs or even testing

In the case of sudden darkness, such as a power outage, the photoluminescent material is immediately visible. Made with photoluminescent pigments, these signs can absorb and store energy from ambient light.

In the red corner we have the photoluminescent exit sign. Photoluminescent (glow in the dark) pigment Paperwork – due to their nature, these need to be registered with the US Nuclear Regulatory Commission.Once the lifespan has expired, there is a high cost for disposal as well Disposal – the costs don’t stop at the purchase price.High cost – starting in the upper $200’s, there is a high entry cost.Code compliant – meets UL924 and NFPA 101 life safety standards.Easy installation – no electrician needed.

Set and forget – truly self-contained and maintenance free.

Click here to see our full line of tritium exit signs. It’s the same technology used in watch hands and firearm optics. This all happens without the need for any outside power or intervention. Electrons emitted by the gas bombard the phosphor causing it to produce illumination. These signs are lit by tritium gas, which is contained within hermetically sealed, phosphor-lined glass tubes. In the blue corner we have the self-luminous tritium exit sign.
