Photoluminescent Exit Signs

A new technology, the photoluminescent exit sign, is changing the way people think about escape and safety products. For a long time, facility safety devices represented a constant compromise--on the one hand, they needed to remain on all the time for the sake of safety, but on the other, all that up-time could amount to sky-high electric bills. New luminescent technology has changed this landscape permanently, ushering in a new era of one-time costs and greatly increased reliability.

What is a photoluminescent sign? Generally, such signs use a number of chemically treated layers in tandem to create constant light that will last for years at a time. This isn't the glow-in-the-dark novelty plastic so many of us played with in our youth. This is permanent light, the kind used in Navy Seal watches and a growing number of related military applications.

The advantages of such an approach are manifold. Probably the biggest is the financial savings associated with the approach. Incandescent bulbs can cost as much as $40 per year, per sign, and even LEDs can draw considerable power over months and years. When you take your signs off the grid entirely, you never have to worry about those mounting bills for each new sign.

Another important advantage is the comparative consistency of these products. Because there is no power source to rely upon and no battery to wear out with time, such signs will continue to stay lit no matter what kind of event strikes that facility. No matter whether it's fire, flood or earthquake, you can rest easier knowing your exit passages will remain clearly marked at all times.
