Difference between revisions of "ANSI White"

This standard was adopted by companies like [[Cree]] and [[Philips Lumileds]] to describe the tint of their LED products. They divided each ANSI quadrangle into four quadrants to get bins like 1A, 1B, 1C, and 1D being divisions of quadrangle 1 (6500K). Tints lying outside of the ANSI standard, above and below the quadrangle, are given names like 1R, 1S, 1T, and 1U. Towards the cold end of the spectrum a non-ANSI quadrangle, quadrangle 0, was added. 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.
