For high power LED's the Nichia chromaticity binning codes are now based on [[ANSI White]] quadrants. A bin of SW50 is an ANSI quadrangle of 5000K (SW45 is 4500K and so on). Forward voltage bins are L (2.7-3.1V) and M (3.1-3.5V). | For high power LED's the Nichia chromaticity binning codes are now based on [[ANSI White]] quadrants.

The 119A and 219A series seem to be identical on the top, with the difference being the layout of solder pads on the bottom. The 219's solder pads | The '''Nichia 119A and 219A''' series seem to be identical on the top, with the difference being the layout of solder pads on the bottom. The 219's solder pads match the [[Cree]] XP-G which is the same physical size of 3.5mm (the Nichia board is 0.2mm thinner) with nearly the same voltage, current, and output. There are at least three variations with different product numbers based on the color temperature: | ||
* The '''NVSSW119A''' and '''NVSW219A''' series LED's are available up to a B14 flux bin. | * The '''NVSSW119A''' and '''NVSW219A''' series LED's are available up to a B14 flux bin. | ||
