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.

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, a run of Xeno flashlights, and L3 Illumination's 1xAA twisty L10.
