For high power | For high power LEDs 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). | ||
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 '''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 '''NVSSW119A''' and '''NVSW219A''' series | * The '''NVSSW119A''' and '''NVSW219A''' series LEDs 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 '''NVSW119A-H3''' and '''NVSW219A-H3''' have a neutral tint of 5000K and have a maximum flux bin of B12. | ||
* The warmer (2700-4500K) high [[Terminology#CRI|CRI]] '''NVSL119A-H1''' and '''NVSL219A-H1''' have a maximum flux of B11 but a CRI as high as 92. | * The warmer (2700-4500K) high [[Terminology#CRI|CRI]] '''NVSL119A-H1''' and '''NVSL219A-H1''' have a maximum flux of B11 but a CRI as high as 92. | ||

These same LEDs were also incorporated into some [[Malkoff]] drop-ins, a run of Xeno flashlights, and L3 Illumination's 1xAA twisty L10.
