The Chinese knock-off existed before the QB, no? "For sale you best multiple band grow led." I am betting they'll just change it to mono-white with same style cheap LEDs.

What alum angle did you use? 1"x1"x.25"?

~115w

Edited.. @ttystikk @dandyrandy Pwm? Or cameras sensor? https://www.google.com/url?sa=t&source=web&rct=j&url=http://www.mikewoodconsulting.com/articles/Protocol%20Summer%202011%20-%20Rolling%20Shutters.pdf&ved=0ahUKEwiIv7uT0rfRAhVG5SYKHYI6AjEQFghDMAo&usg=AFQjCNGDUR8aOEK9aWJb8zrw6JB-2KhK1A

What??!!! I just spent over 150$ on led bulbs for my house! Those gu10 mr16 dimmables hit the wallet the hardest, 9$ a bulb :(

Mmmaybe, I am still in planning stages. Probably will want min-dim 700ma for this tent. I have a 60x31x80 for perpetual auto. Will take all advice though, I have like 12 sheets of scribble paper that I keep staring at.

Which way are you going to power them? I was thinking similar, one driver (320-1400) for all 6 @ .46a / 48w a board.

What will the slate(xx) price be?

2 boards on a HLG 240-1050 series wired 2s@1050=~230w (115.3w per board) 3 boards on a HLG 240-2100 parallel wired 3p@2100=~225w (74.8w per board) 4 boards on a HLG 240-1050 parallel-series wired 2p+2s@1050=~210w (52.5w per board*) *[I just used 500ma for simplicity]

With the 320-1400, NGL engineering page shows a 2 parallel + 2 series (2p+2s). Can this be furthered to 3 parallel + 2 series (3p+2s)? If I understand correctly the Vf is the same just the current is in thirds instead of halfed. If correct, the 4 qb's (2p+2s) would be @ .7a, so 6 qb's (3p+2s)...

@1000ppm there is a quick reference chart on https://northerngrowlights.com/pages/engineering Closest listed to 1amp is the 1050, 109.9(volt) 1050(amp) 115.39(watt) 166.7(lumen/watt)

Splash guard mostly. I'm brainstorming what to light my 60x31. And as the amount, unsure, maybe 4 on the 320-1400 driver. If I go that route, for sure window screen framing / lexan. Built to fit. I'm not cramming plants in, I like some elbow space.

No offense taken. I was referring to something to drop the qb board into. http://m.ebay.com/itm/20W-289LEDS-Square-LED-Panel-Grow-Light-for-Garden-Hydroponic-Greenhouse-Lamps-/ Just for the case indeed. If I had one & the experience. I was actually thinking of buying aluminum track...

I dreamed of a freezer/fridge build like that, but I am going the way of tent. Currently looking for el-cheapo led fixtures that'll fit the qb b4 I buy more things. The 289 led eBay panel for <35$ might be good, 310mm x 315mm.

I did find an older RIU thread on those LEDs from Jan2014. Your best bet may be to save the cases for either a diy project or get a few bucks back buy selling them for parts. My Google-fu must be sucking. I can't find what triple stack refers to so for now.. Edit: Wait.. The lens? Makes...
