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.
oldmac Reviewed by oldmac on . LED grow lights... input please. Hello guys, I'm exchanging eMails with a representative from a LED company. I asked him if they could produce a custom light for growing, and here's what he told me: Our options are as follow: 940nm, 850nm, 660nm, 630nm, 610nm, 590nm 570nm, 530nm, 510nm, 470nm, 460nm, 400nm and a total of 64 LEDs in the bulb.
