1108 PRODUCT INFORMATION Binning LED TECHNICAL INFORMATION PSG11 TECHNICAL INFORMATION www.acuitybrands.com These bins are grouped as quadrants around the standard chromaticity lines (shown below in blue) for a specified color temperature. The larger the bin size, the more variation around the standard color temperature is accepted. Conversely, smaller bin sizes maintain a tighter control of color variation. In 2008, ANSI and NEMA collaborated to establish a bin standard ANSI C78 377A1 which has become a minimum requirement for Energy Star certification. This standard specifies a bin size that approximately correlates with the degree of color variation we experience today with commercial CFL sources. This allows for some degree of perceivable variation in color temperature among white light sources. For more information about color binning and bin sizes, consult ANSI C78 377A. 1 Complete and proper name: ANSI NEMA ANSLG C78.377-2008 American National Standard for Electric Lamps-Specifications for the Chromaticity of Solid-State Lighting Products. 0.38 0.37 0.37 0.38 0.39 0.40 0.36 0.35 0.34 0.33 0.32 0.31 0.30 0.29 0.28 0.36 0.49 0.48 0.47 0.46 6500 K 5700 K ANSI bins 5000 K 4500 K 4000 K 3500 K 3000 K 2700 K 3500 K 3500 K (Continued) BINNING
