I'm contemplating getting two more of the V1 boards, actually... If I get to them before they sell out, that is. Planning a new, smaller tent, and although I'd really like to try the added 660nm in the new boards, the price of the old ones is just too good to resist. Besides, I've been very happy with the now-venerable 561c in straight 3000k, so I'm not too bothered about giving up the reds. I will probably add a 660nm QB11 to one of my QB120 fixtures at some point, just to see what all the to-do is about.

I want to get some of these to some of my friends here in Humboldt County. See what we can do with them.

I apologise for me misunderstanding what you wrote and for my tone and choice of words.

I wanna build a r-spec board. Would a sheet of aluminum 24inx24in 1/4in thick work for running 4 qb288 with a hlg 480h-c2100a

at those prices you cant go wrong, man. im yet to use any added 660 either...have you thought about adding UV?

Yeah, I've thought about it, but I think I'll wait until there's a good, affordable DIY LED option, because the way my lights are set up, I can't easily integrate floros. And everyone has been more than happy with the weed coming out from under straight 3000k, so I don't feel too rushed to try enhancements right now!

no problems w my V1 and I am about 2 years. Aren't they like 5% less efficient than v2. I wish I had more space and I would buy more V1. Imagine the cost of a diy 550 these days.. Like 250 usd w driver. Too bad for Canadians as the minimal shipping cost seems to be about 40 usd.

Why not use single heatsinks with angled aluminum. Lighter. Otherwise a solid piece would probably work. @Chronikool built some fixtures with a solid piece ( nice fixtures.. ). I thought I saw them not too long ago on this thread. You have a lot of options with quantum boards these days.

1/4" thick?!? Jesus Christ. That'll do the fucking trick just fine n' dandy there, won't it now?

I’m ready to do a side by side comparison, I will use DE hps 400 and kingbrite v3 UV IR lm301h 4000k for 525 total watts vs kingbrite v3 UV IR lm301h 3000k + kingbrite v3 UV IR lm301h 4000k + viparspectra 300 for 385 total watts. I can’t prove the “actual draw” but I will be able to see for myself what happens when growing the same strain under the different light. I don’t have the set up yet for a better test but I will be working on it. Some one else show a time elapse side by side comparison

And easy to toss a mercury vapor lizard light in the tent for a few hours a day for uvb. I’ve been testing leds and uvb amounts on red lettuce

Buy a meter for $12 and you won't have that issue: https://www.amazon.com/Digital-Electricity-Analyzer-Monitoring-Equipment/dp/B07M8JKLG5

did you see any of Or Grows UV stuff? most of it was on another forum, he did a really good 3 way side by side

Yes that's right, about a 5% difference between the 561C and the 301b, yet still about 7% more efficient than most COB.

Use the "RIU10" discount code on HLG's site and it should offset shipping.

I've been running QB's since they were released and I replaced all my former lighting with them except for one COB light. I've been so pleased with them and with HLG's customer service, you couldn't give me another light!
