Product Bin and Labeling Definitions
Decoding Product Bin Labeling
In the manufacturing of semiconductor products, there are variations in performance around the average values given in the
technical datasheet. For this reason, Lumileds bins LED components for luminous flux or radiometric power, color point, peak or
dominant wavelength and forward voltage.
LUXEON UV U1 LEDs are labeled using a 3-digit alphanumeric CAT code following the format below:
A B C

designates radiometric power bin (example: D=400 to 450mW, J=700 to 750mW)
designates peak wavelength bin (example: A=380 to 385nm, E=400 to 405nm)
designates forward voltage bin (example: 8=2.8 to 2.9 volts, 0=3.0 to 3.1 volts)
Therefore, a LUXEON UV U1 with a radiometric power range of 400 to 450mW, peak wavelength range of 400 to 405nm and a
forward voltage range of 3.0 to 3.1V has the following CAT code:
D E 0
LUXEON UV U2 LEDs are labeled using a 4-digit alphanumeric CAT code following the format below:

designates radiometric power bin (example: A1=400 to 600mW, D1=1000 to 1200mW)
designates peak wavelength bin (example: A=380 to 385nm, E=400 to 405nm)
designates forward voltage bin (example: 8=2.8 to 2.9 volts, 0=3.0 to 3.1 volts)
C
Therefore, a LUXEON UV U2 with a radiometric power range of 1000 to 1200mW, peak wavelength range of 400 to 405nm and a
forward voltage range of 3.0 to 3.2V has the following CAT code:
