Nichia

Nichia is a Japanese LED company. Their low powered 5mm LED's are still used in some flashlights.

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).

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 (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 NVSW119A-H3 and NVSW219A-H3 have a neutral tint of 5000K and have a maximum flux bin of B12.
 * The warmer (2700-4500K) high CRI NVSL119A-H1 and NVSL219A-H1 have a maximum flux of B10 but a CRI as high as 92.

In 2012, Illumination Supply obtained a number of NVSL219A-H1 LED's, which became a favorite of modders due to the high CRI and 4500K neutral tint (Cree LED's with such a high CRI typically have a much warmer tint). These same LED's were also incorporated into some Malkoff drop-ins. Datasheets
