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 TX LEDs are labeled using a 4-digit alphanumeric CAT code following the format below:

A B C D

A

–

designates luminous flux bin (example: M=210 to 220 lumens, R=250 to 260 lumens)

B

–

designates correlated color temperature bin (1=6500K, 2=5700K, 3=5000K, 5=4000K, 6=3500K,

7=3000K, 8=2700K)

C

–

designates SDCM bin (3=3-step MacAdam ellipse, 5=5-step MacAdam ellipse)

D

–

designates forward voltage bin (example: P=2.50 to 2.75V, R=2.75 to 3.00V)

Therefore, a LUXEON TX with a lumen range of 210 to 220, color bin of 7 for 3000K parts, 3-step MacAdam ellipse 80CRI and a

forward voltage range of 2.50 to 2.75 has the following CAT code:

M 7 3 P

Luminous Flux Bins

Table 5 lists the standard luminous flux bins for LUXEON TX emitters. Although several bins are outlined, product availability in a

particular bin varies by production run and by product performance. Not all bins are available in all CCTs.
