Specially chosen 630 nm Red LEDs combined w/ our special
Lexan® Diffuser Panel is at the heart of the new Solid Letter design
Never has a red LED exit been so visible to the color-blind.*

Research suggests Green on Black may be the most visible to color-deficient observers.
(That's 1 in 50 men and 1 in 2500 women!!!)

After learning of recent color-blind research, we decided to go with the 630nm LED in our new Solid Letter design. To "normal" sighted people it appears a little more orange than the usual red EXIT, a difference only noticeable when one of each type exit is placed side by side. However, that's enough for most exit manufacturers to dash toward the perceived largest seller; the standard red. We have chosen, instead, to err on the side of color-deficient observers until we learn just how important the difference is. We encourage you to do the same.

Specify 630nm Red on White or Green on Black LED Exit Signs.
