So question. Does QBs put off UV? Was thinking of getting some glasses but not sure if its worth it being that I have corrective lenses and id be blind with just grow glasses.

I never thought I needed them until,today I forgot I left a pump running and went in there after having just woke up and I,damn near went blind despite shielding my eyes with my hand and looking away.

Makes me feel,foolish when I saw pictures,of these lights on this thread and thought they were,dim. Lol.

No UV from LED lights.

Hey guys just received my QB135. I have a mars hydro 300 in the tent now in week 2 of flowering. I was thinking of switching the lights now. Would anything happen to the plants?
Definitely switch ASAP, just hang the QB higher than the Mars and bring it down an inch a day until you're happy. The idea is to harden the plant off to the new spectrum and intensity without scorching it.

Yeah pictures really don't do it justice if these things photographed well they would sell out even faster

Qb120 = $30 for 60 watts
4 of these = $120 for 240 watts
driver = $60

Am I missing something or does this allow me to build a 240w light for about $200?

Has anyone built one of these? Can I see some pics?

Oh yeah...

And I'm building a second one very soon. There's a dude over on GC who runs 8xQB120s in his flowering light. And if you go back through the pages of this thread, you'll find others planning similar builds. Welcome aboard!

Awesome build dude.
You think I could fit 2 of your builds for 480w in a 4x4 tent?
i think so.. your fixture is 21x26
2 of these side by side would be 42x26
My tent is 48x48

hmmmmmmmmm i think I'm gonna do it lol

Do it!! You can absolutely fit them. But think more like 500 watts at max - don't worry, I have proof the boards can take it without breaking a sweat!

Edit: you may want to spread your boards out a little more than I did, since you have a wider canopy to cover. Eight boards should still rock it. There's another guy on GC who's planning a build like mine for his 3x3, and I have no doubt it's going to kick much ass too.
