A manufacturer of LED lighting for mass transportation vehicles was having trouble finding the right diffuser for a railcar lighting fixture. The translucent white polycarbonate that they were using did not have sufficient light transmission to meet the vehicle light level requirements. It also failed to adequately diffuse the LED lights, which resulted in “hot spots”.
TUFFAK® Lumen XT tested in application—provided greater light transmission, LED hot spot elimination
Curbell suggested they evaluate TUFFAK® Lumen XT polycarbonate sheet, which has higher light transmission and also does an excellent job diffusing LED hot spots. This allowed the manufacturer to produce a fixture that met the light transmission specification for the job and eliminated the LED hot spots.
