Hey veggii,

Your right, in the last year we are starting to see Kelvin and terms like "warm" and "cool" white applied to LEDs.

Unfortunately for me the warm whites I picked to use for an experiment did not work well and had me confused......untill I saw the device tested @ the LED museum and saw the spectrograph. A real neg spike at the blue range and min far red. It was makeing most of it white in the orange amber green ranges, not the broad curve of a fluoro.

They have made and will continue to make great improvements in high power LEDs especially the whites that currently have so many applications. Spectral analysis is a must.
