QB96 Elite V2 w/ SSTX heatsink question

I'm not slamming you, I'm just pointing out that "in nature" cannabis evolved under a very different photoperiod to the one you suggested. Just have a think about stuff before you write - that's all people are asking. They're not slamming you for trying to help.

Building testing fixture today, 1/2” angle alum, will be just shy of tent perimeter dimensions, with sliding/removable rails for max 2d positioning of each quantity combo (single light, double, triple...octo).

Mapping approach will be to find “best” 2d spacing for even spread, then map using height & dimmer setting as variables.

No need to applaud my obvious drafting expertise...

No problems I don't think, he just blasted your taping of drivers and your extremely long lengths of wire and told everyone to NOT do what you did. He posted your first pic with a text overlay.
So what? A$$wads there, here, everwhere...

You know what i’m sayin...to you...right?

I would absolutely fucking love to see a PPFD map for four QB96s, at 150w each, in a 4x4 tent.
Thats exactly my plan. I don't have a meter or anything to map it, but i'll provide some real world results as soon as i get a full grow under it. just tested the light today, 4 96 elites on a 600h-54b driver. with the pot all the way up it runs at 638 watts, or about 160w each.

what i don't understand, is with the pot all the way down it stays on and runs at 40w, 10w each. i'm using the cased potentiometer i ordered from rapidled. i expected it to dim all the way to off. can someone explain why this doesn't happen?

Lookin forward to seein how they do for you. What is the growspace footprint, your using them for?

Hopefully in next week or two, i’ll have some info on 4 that might help.

I agree. I would think boards will have a better overall similar PAR number though.
I would tend to agree. But if the spectrum can be shown to make a difference, and the distribution of light is acceptable, it would make another good low-cost (roughly $1/watt, with driver) setup for a 4x4.

I'm with @Rahz though. This type of light (mini-PCB), with the added red, would be compelling at around 30-50w per board. Seems like it would offer a little more diffusion than your average COB, while fitting into one of the more popular

Awesome. Start up a thread! Do you happen to have a lux meter? I'm extremely interested in seeing what kind of uniformity you get at various hanging-heights.

so, this beats fishing leader approach...

Totally flexible positioning in 3D space...and easy leveling, too...worthwhile afternoon...

Time to roll some rope...,
