Do not know your country, but if you are in Europe there are other suppliers that offer a pcb board ,with lm561c.I have seen a prototype at a growing equipment exibition, (efficiency of 2,7mmol/j at 100w,passive cooling,but I do not remember all data exactly )available from December.Good question! The guy who is designing/building them knows his stuff and takes a very methodical scientific approach. He has all the kit to test his products and is selling them at a very reasonable price also.
I believe he doesn't ship internationally or I'd be the owner of a couple of his boards......

I made a 720 led PCB? Wow, I musta doubled up on my Adderall by accident!
@Randomblame, I think you're a little mixed up man... @Budies 101 built the boards you're talking about, not @Rider509

UV is always lurking in the back of my mind.
I like trying out the new technology , proving it works, showing friends. I'm like an unofficial hlg rep as I've sent a few orders their way already

No strips yet but if I do it'll be the 2ft ones as I prefer lots of smaller fixtures I can drop in and out as requiredGot any strips?
Got the good old CXBs and a qb in tent as we speak flowering and a GG board + 660 and 420nm vegging in another area and 3 x citizens 1212s vegging in another area.
Cobs and Boards grow great plants

Yeah those buds look anorexic. Yodaweed was right all along, QB's are basically only good for side lighting.

If the man had any self-awareness, he'd feel embarrassed about how foolish all his QB-bashing has made him appear. Remember, according to Yodaweed, quantum boards "lack any type of usable intensity", so everyone here who's growing amazing nugs under QBs is obviously having a pipe dream!Yeah those buds look anorexic. Yodaweed was right all along, QB's are basically only good for side lighting.
The really amazing thing is that he's still banging on that drum, trying to give new people advice about the proper application for boards he doesn't use. I don't get it.

First time I've seen someone comment that COBs have a spectrum advantage. Data?

I've not seen anything that would indicate a big disparity in spectrum either. Can ya show us what you mean, Humple?

But what qualifies the differences as favoring COBs? Why are they better?
