GTR ULTRA: The original bad boy of backup LED bulbs is better and brighter than ever. With more light output. More reliability. More modern construction. A longer lifespan, all wrapped into the same universal package that made the original so popular: The new Ultra Reverse bulbs are the best way to back up with the visibility and safety that GTR Lighting customers demand.
NEW WITH GEN TWO: As if the output from the first gen wasn’t enough, GTR has upped the ante with the new Ultra version. Whereas the original version produced 1000 lumens each, the new Ultra bulb produces 1200 effective lumens, which is far more than what a typical incandescent bulb produces in the same application. The original used nine LED chips per bulb. Gen Two? Fifteen.
