Thanks for the info. Wasn't that comparing SK @ 440w to LEC's 350w? It seemed to me from the graphs that it worked out about the same considering the power difference?I work at a grow store and we have both the SK400+ 90 deg. and a Sun Systems LEC 315 hanging on display.
The light performs just as the company claims.
I never understood Rami's antipathy to COBs. It seemed strangely religious, like "they don't exist!" Something always seemed off about that. (Contrails and Elvis conspiracies. ). He's definitely a passionate guy.
