For this reason, Lumileds bins LED components for luminous flux or radiometric power, color point, peak or dominant wavelength and forward voltage. LUXEON MX LEDs are labeled using a 4-digit alphanumeric CAT code following the format below: A B C D Where: A – designates luminous flux bin (example: M=630 to 680 lumens, T=970 to 1040 lumens) B – designates correlated color temperature (CCT) bin (example: 1=6500K, 2=5700K, 3=5000K, 5=4000K) C – designates color bin (example: 3=3-step, 5=5-step, 7=7-step) D – designates forward voltage bin (example: F=10.50 to 11.00V, G=11.00 to 11.50V) Therefore, a LUXEON MX 12V with a lumen range of 630 to 680, color bin of 4000K, 5-step MacAdam ellipse and a forward voltage range of 10.50 to 11.00V has the following CAT code: M 5 5 F Luminous Flux Bins Table 5 lists the standard luminous flux bins for LUXEON MX 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. Table 5.
