Wow.. lot of mudslinging going on and there's one thing that's for sure - seems like we don't have any grow journals with quantum boards or anything similar to that just yet. Myself I believe they may be a lot like the big 5 and 8u CFL bulbs which put out an excellent spectrum but suffer quite a bit of lumen loss past just a few inches. May just be the ticket however for veg lighting? We'll see, but for flowering I won't be holding my breath.
Still, major props to
@robincnn for constantly pushing the envelope on led tech! This fact simply has to be acknowledged. Remember out of all the vendors he's always been the first to bring the latest and greatest gear to market.
