# 2700K

This standard was adopted by ~~companies like~~ [[Cree~~]] and [[Philips Lumileds~~]] to describe the tint of their LED products. They developed the concept further by dividing each ANSI quadrangle into four quadrants to get bins like 1A, 1B, 1C, and 1D being divisions of quadrangle 1 (6500K). Towards the cold end of the spectrum a non-ANSI quadrangle, quadrangle 0, was added. Tints lying outside of the ANSI standard, above and below quadrangles 0, 1, 2, 3, 4, and part of 5, are given names like 1R, 1S, 1T, and 1U. Cree subdivides regions 5, 6, 7, and 8 into even smaller subdivisions to get bins like 5A1, 5A2, 5A3, and 5A4~~, while Lumileds would call all~~ of those 5A.

[[Luminus]] does something similar by subdividing the standard ANSI quadrangles and adding their own outside of those limits.
