The CR Series from Cree, which includes CR 14, CR 22 (shown), and CR 24, is made up of LED architectural troffers for commercial lighting. The collection delivers high-quality light, longer life than comparable compact fluorescent systems, and greater energy savings, with estimated payback of less than a year for a typical office installation. The fixtures eliminate flickering, poor color, and ineffective dimming, and contain no mercury. The troffer family is powered by Cree TrueWhite Technology and delivers 90 CRI and 110 lumens per watt. The three models measure 1' by 4', 2' by 4', and 2' by 2'.
