Yes, I've a qb board on a slate2 at 150 wall watts with no worries so far.Do these boards run passively cooled with the heatsink on the back?
I'm interested in swapping out my blurple cob. It's kinda so so performance.
Kind of made for HID bulbs aren't they? Or are you just using it for the air cooling feature? I don't think you even need air cooling with the QBs. I suppose you could still use it if you wanted, just doesn't seem that appropriate. One LED out might not cause a problem current/voltage-wise but probably several would.
About the cracked LED. If it kills the whole board you could probably just solder jumpers on to bypass that LED. I guess they're probably designed in such a way that they still work when some are out. The company rep didn't actually tell us if that's the case or not. At least not right here, maybe somewhere else.
I see. Not a bad idea actually, though a little costly unless you already had them. Not many people use a cooled hood for LEDs but it would certainly help get rid of any heat, keep it out of the grow space. That was some innovative thinking.Yea they add heat for sure just not as much as hps. Currently have 12 boards 6 per raptor and need 12 more boards if all goes well. 4 hoods total.
Worked out pretty slick, just need to see the final outcome in a couple months.
Got any pics? Interested to see how that looks.Yea they add heat for sure just not as much as hps. Currently have 12 boards 6 per raptor and need 12 more boards if all goes well. 4 hoods total.

IIRC watts are watts and they add the same heat loads. BUT because half the wattage is used it should theoretically cut cooling loads in half. But the same 3.41 btuh per wattAny pics of this setup?
Have you started testing them yet?
My thoughts on this is that it would greatly reduce A/C expense even with led and make running a sealed room very easy with even the smallest A/C unit
Pretty much perfect, actually.2 260w kits finally shipped. Do I need anything additional? Or does kit come with everything?
Is this overkill to hang over a 40"x40" flood table?
Yep, that's how it works. With small heat loads more gets dissipated into the space, so the effective need for cooling usually drops by more than half.IIRC watts are watts and they add the same heat loads.

Doesnt look to bright in the pic but...
I have a vertical HPS on the other side and this is drowning the HPS out. Not sure how plants are seeing the light but from a human perspective the 6 banger quantum has far more light.
What is the total wattage 6 boards runs at?Cut some L aluminum at 24 inches x 2.
Inserted these in between the Quantum heat sinks to hold them up.
Used gromted washers and am going to seal them with polyurethane.
Might add some reds in the middle heat sink later. Wrapped it in Orca film for now for reflectivity purposes. Orca is super thick tough material.

Probably about 600 - 650w. 2 HLG 320 2800sWhat is the total wattage 6 boards runs at?
Now that Is how a great company operates .... No BS .You can email HLG, u get a USPS priority box in 2 days with replacement board, box will have a prepaid box inside to return defective board
