Recently, GE Lighting Solutions has rolled out a series of Tetra® LED lighting systems designed for channel letters.

The new products feature outstanding uniformity and use fewer modules than previous models. Below are the main specifications:
 
Tetra miniMAX—for small channel letters 1.5 inches in depth or greater, the new products efficacy is 43 percent greater than the previous Tetra miniMAX with 81 lumens per watt compared to 57 lumens per watt, uses 26 percent less energy and has 80 percent wider stroke spacing in a 4-inch sign. Also power supply loading is increased by 50 percent, from 40 feet to 60 feet.

Tetra MAX and Tetra MAX High Output—for medium channel letters 4 inches deep and up to 36 inches high. The new Tetra MAX is 25 percent brighter (75 lumens per foot versus 60 lumens per foot) and its efficacy is 33 percent greater (59 lumens per watt versus 78 lumens per watt) than previous generations. Tetra MAX High Output is 92 percent brighter at 115 lumens per foot with 36 percent greater efficacy, and uses the same layout rules as the new Tetra MAX so sign makers can offer two brightness and cost options with no additional layout prep work. Stroke spacing for both is also improved by 80 percent in a 5-inch deep sign (9 inches versus 5 inches).

Tetra PowerMAX—for large channel letters up to 4 inches deep and 36 inches or taller, Tetra PowerMAX increases brightness by 25 percent over its predecessor (182 lumens per foot versus 146 lumens per foot) and decreases costs by increasing stroke spacing by 50 percent in a 4-inch deep sign (9 inches versus 6 inches).The next-generation Tetra LED lighting systems feature GE’s patented technology OptiLens™ that maximizes LED performance by capturing otherwise wasted light and redirecting it toward the illuminated surface to create an exceptionally uniform channel letter. This unique lens technology optimizes each LED to allow for wider stroke spacing, which helps reduce the amount of material needed in each sign.
