Product Bin and Labeling Definitions

Designing with SignalSure

Flux bins supportable for car programs depend on product color and program start- and end-of-production date. Flux
roadmaps by year and product color are maintained and available from the sales representative. Please contact your local sales
representative to request the flux bin range with best supportability for program timing.

Decoding Product Bin Labeling

In the manufacturing of semiconductor products, there are variations in performance around the average values given in the
technical datasheets. For this reason, Lumileds bins the LED components for luminous flux, color and forward voltage.

SignalSure 250 LEDs are labeled using a 3-digit CAT code following the format below:

A B C

A – designates luminous flux bin (example: J=15 lumens to 18 lumens)

B – designates color code (example: 3=612nm to 618nm)

C – designates forward voltage bin (example: B=2.19V to 2.31V)

Luminous Flux Bins

Table 5 lists the standard photometric luminous flux bins for SignalSure 250 emitters. Product availability in a particular bin varies
by color and platform start-of-production date. Contact your local sales representative for best supportability of programs.
