Kit Number System
Cree LED lamps are tested and sorted into performance bins. A bin is specified by ranges of color, forward voltage, and brightness. Sorted LEDs are packaged for shipping in various convenient options. Please refer to the "Cree LED Lamp Packaging Standard" document for more information about shipping and packaging options. Cree LEDs are sold by order codes in combinations of bins called kits. Order codes are configured in the following manner:
