Cree(R) XLamp(R) XR LED
Binning and Labeling
Cree XLamp LEDs combine the brightness of power LED chips with a rugged package capable of operating in excess of one watt. 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 or chromaticity) and brightness (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 dominant wavelength 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 LED Data Sheets.
XLamp LEDs are sold by order codes in combinations of bins called kits. Kits include a minimum of two dominant wavelength groups and two brightness groups. Order codes are configured in the following manner:
Spatial pattern L = Lambertian G = Global * Kit number XR7090AA-BC-0001 Viewing angle (1 = 100 degrees)
7.003 ote: CLD-AP0 Application N
Color
Color Codes RY = Royal blue AM = Amber BL = Blue RO = Red-orange CN = Cyan RD = Red GR = Green WT = White
* Global - an alternative white product that has higher efficacy with slightly lower color uniformity. Kit number 0001 is always the order code encompassing the broadest range of color and brightness groups.

Order Codes Explanation
Spatial pattern Dominant wavelength or chromaticity group Forward voltage group (used only for red & amber) XR7090AA-BC-DD-EF-G-HHHH Special code When measured in lumens E = Brightness group F = Brightness sub-group (default 0 means no sub-group) When measured in milliwatts F = Brightness group Viewing angle Color
Royal Blue XLamp LEDs are tested for radiant flux and are placed into one of the following groups:
Group 10 11 12 13 Minimum Radiant Flux (mW) @ 350 mA 175 210 250 300 Maximum Radiant Flux (mW) @ 350 mA 210 250 300 350
Performance Groups - Dominant Wavelength
Monochromatic XLamp LEDs are tested for dominant wavelength and placed into one of the following groups.
Color Royal Blue DWL Group D4 D5 B3 B4 C2 C3 G2 Green G3 G4 Amber A2 A3 O3 O4 R2 Red R3 R4 Min. DWL (nm) @ 350mA 455 460 465 470 500 505 520 525 530 585 590 610 615 620 625 630 Max. DWL (nm) @ 350mA 460 465 470 475 505 510 525 530 535 590 595 615 620 625 630 635
Performance Groups - Brightness
XLamp LEDs that are tested for luminous flux are placed into one of the following groups:
Group F G H J K M N Minimum Luminous Flux (lm) @ 350mA 10.7 13.9 18.1 23.5 30.6 39.8 51.7 Maximum Luminous Flux (lm) @ 350mA 13.9 18.1 23.5 30.6 39.8 51.7 67.2
Blue
Cyan
Red-Orange
In order to minimize the perceived luminous flux variation among white lamps from the same reel, Cree bins to tighter luminous flux sub-groups. These sub-groups are defined below.
Group Code K2 K3 M2 M3 N2 N3 N4 Minimum Luminous Flux (lm) 30.6 35.2 39.8 45.7 51.7 56.8 62.0 Maximum Luminous Flux (lm) 35.2 39.8 45.7 51.7 56.8 62.0 67.2
Amber and red XLamp LEDs are binned according to forward voltage at the rated current. Cree's forward voltage groups are:
Forward Voltage Group C D E F Minimum Forward Voltage @ 350 mA 2.0 2.25 2.5 2.75 Maximum Forward Voltage @ 350 mA 2.25 2.5 2.75 3.0
