Cree XLamp XR-E Blue LED
Binning and Labeling
Cree XLamp XR-E LEDs combine the brightness of power LED chips with a rugged
package capable of operating in excess of three watts. XLamp LEDs lead the solid-
state lighting industry in brightness while providing a reflow-solderable design that is
optimized for ease-of-use and thermal management. Lighting applications featuring
XLamp LEDs maximize light output and increase design flexibility, while minimizing
environmental impact.
This application note describes Cree’s procedures for sorting XLamp LEDs by color
(dominant wavelength) and brightness (luminous or radiant flux) and then lists the
order codes encompassing these color and brightness groups for easy reference.
Nomenclature
XLamp LEDs are tested and sorted into performance bins. A bin is specified by ranges of color and brightness. Sorted
XLamp LEDs are packaged on reels. A reel contains lamps from one bin and is labeled with its bin code. For more
information on packaging, see the XLamp XR-E Blue LEDs data sheet.
Series
XLamp LEDs are sold by order codes in combinations
