They use CW...the most efficient after all. I have tried to push WW on them so hard it's not even funny. As long as they are enhancing with red, CW will probably be the only thing you see from them. But you never know if he watches my cobs do work with just WW...self five!
I posted that AT spec sheet well before the release of the new AT line and was bitching about it already.
Since the at600 was originally the at480(using the original chips...nichia 183's)...I think that much of the spec sheet was not updated to the new chips(219). Not excuse for it, specially of their prestige...but that is where I think all these little inconstancies come from. AT told me that my light(proto) only has the 260lm bin in it...as in 260lm per 700ma(2watts). But when I get another(hint hint), it will be the production with the top bin.
This is a spectoradiometer reading I did on my own of my proto at600...a favor from a friend that let me play a little.
Look at at the breakdown...pretty stellar imo. plants said so too The grades next to the % are compared to the sun...every artificial light gets failing grades that I saw...no cmh tested though.
