LED Binning

LED binning is the manufacturer’s sorting of produced chips into narrow performance groups — flux bins, forward-voltage bins, and chromaticity bins on the color plane — because semiconductor production scatters naturally around its targets. For luminaire quality, chromaticity binning is the visible one: fixtures built from tight bins (within 3–5 SDCM) look uniform side by side, while loose or mixed binning produces rows of subtly different whites on the same ceiling. Flux and voltage binning affect efficacy consistency and driver design margins. Procurement leverage is simple: reputable fixture makers state the LED platform and the SDCM tolerance; evasiveness on binning usually predicts patchwork ceilings.
