Tetra<sup>®</sup> PowerMAX Channel Letter Sign Lighting

Tetra PowerMAX

Our brightest solution for large channel letters
Tetra® PowerMAX is the LED system for large size channel letters that's 3% brighter than our previous product. Tetra PowerMAX features OptiLens™, a patented GE technology that maximizes LED performance by capturing otherwise wasted light and redirecting it towards the illuminated surface. The Tetra PowerMAX LED lighting system delivers bright, uniform light across a large surface area, allowing sign builders to illuminate their signs with less LEDs, reducing overall system costs.

Can cut product required almost in half
Many LED systems use about 13 LED modules in 2 rows to fill a 5-inch deep, capitol "T" channel letter that's 3 feet high. Improved Tetra PowerMAX requires just 7 LED modules to fill the exact same letter (giving up some brightness) while providing outstanding uniformity. That's 46% fewer modules. Tetra PowerMAX stretches stroke spacing to an impressive 11 inches while maintaining remarkable light uniformity on the sign face. It protects customers' brand image while reducing product costs and saving installation time.

12% Greater Loading is a competitive advantage
Our system can now operate 28 feet of product per 60W power supply (up from 25 feet in our previous design) for even greater material and installation labor savings.
