As stated previously, there are several ways LEDs are binned. The most
critical bin criteria that impact product performance are light output
and color temperature. Binning for light output is a very straightforward
linear function. LEDs are individually measured and sorted by lumen
output into prescribed ranges. LED suppliers create their own standard
set of lumen bins and provide clear information on the expected lumen
performance of each of their bin ranges. So, luminaire manufacturers
can easily select the bin (or set of bins) that best meets the lumen
