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 | The 119 and 219 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 seem to match the [[Cree]] XP-G which is the same physical size with nearly the same voltage, current, and output. The NVSSW119A and NVSW219A series LED's are available up to a B14 flux bin. The NVSW119A-H3 and NVSW219A-H3 have a neutral tint of 5000K and have a maximum flux bin of B12. The warmer high [[Terminology#CRI|CRI]] NVSL119A-H1 and NVSL219A-H1 have a maximum flux of B10 but a CRI as high as 92. | ||
