Cree XLamp XQ-B LED 2 x 2 Troffer Reference Design

Cree XLamp XQ-B LED 2 x 2 Troffer Reference Design. This reference design details the design of a 2 x 2 troffer using Cree's XLamp XQ-B LED. This troffer is intended to be used in commercial and industrial applications. These applications, that historically have used U-bend and T8 fluorescent luminaires typically providing 70-80 lumens/watt, can benefit from the energy savings and high efficiency provided by a XQ-B LED-based troffer. The XLamp XQ-B LED is designed specifically for applications that require a broad light distribution. The breakthrough light-emission pattern, where more light is directed toward the edge rather than center of the LED and the high flux output and efficacy offered by the XLamp XQ-B LED make it a particularly strong candidate for use in a troffer
