Abstract
A troffer light fixture has a housing with a LED assembly positioned in the housing. The LED assembly includes at least one LED array comprising LEDs of at least two different colors. The LED assembly includes a first LED array having a first LED on a first string and a second LED on a second string and a second LED array having a third LED on a third string and fourth LED on a fourth string. A wide lens covers the LED array. A reflector assembly has a first reflective surface and a second reflective surface reflecting light from the at least one LED array laterally across the width of the wide lens. Alternatively, the LED array may be approximately one-half the width of the wide lens and the reflector may be eliminated.
