That's a cool one for a Vero build. Do you need a holder for those?
What's the advantage of using a holder with Vero29?On the Vero 29 holders, the screw goes through both the holder and the COB and you only use 2. No you don't need the holder, but it is only a dollar or 2 each and are worth it. On Digikey, the holder, wire connector, and COB is about $31 per set.
So it seems to you that the COB is secured better as opposed with the default 4 screws installation? And of course a reflector...if you're gonna use one you can't avoid a holder I suppose.Covers wires and pushes down around the edge of the COB. Can also attach, I think, a reflector.
In that example you would need 9 drivers. Will you be set up with 72 ft² of canopy, no walkways included? If so:So, I'm designing a CXA array to cover approx 6x12 space. Still trying to determine if it'd be better to try to fit 3 in 7's across, or just do 2 in 10's. Thinking I might be able to get away with 5 across if I only do 2 in 10's. So, let's say I'm looking at the 6x12. That's 72 lamps. If I'm not mistaken, I can run 4 COB's per HLG185C700, yes? So, that's 18 drivers?
i had a feeling the cxb3590 would be cheaper in the long run to light a larger area, plus the added efficiencey and ppfdIn that example you would need 9 drivers. Will you be set up with 72 ft² of canopy, no walkways included? If so:

PPFD represents PAR photons/second/sq meter. Assuming environmental conditions and fertility conditions are right, PPFD has a direct effect on yield. It is not a linear relationship though. This chart is cannabis specificCorrect, no walk ways. I'll have space to walk around the entire footprint. I'm thinking of only going 2 wide with 10G pots into a SCROG. I know I could probably get by cutting the canopy to 5x12 if I'm only going two across, and that's something I'm considering as well. I could probably handle 3 across in 7s, though.
Supra just hit a grand slam. Great data there. I wasn't really sure of all the specs on the 3590, how well it would do with less chips but I trust your data. For almost the same money that I was going to spend, I can get a 20% boost in PPFD... I have a vague understanding of what PPFD is, but I have no idea how much it effects yield.
I absolutely want to make them aesthetic, that's an important factor for me. You still have to sand and level the heatsink USA sinks, correct? I guess it wouldn't be the worst thing in the world, I'd have an extra set of hands to help me with that part.
If you do decide to sand heatsinks, you can go at it with wet sanding 60 grit or 80 grit to get it flat and smooth the scratches out with 220 and smooth the surface with 600. That will quickly and hugely improve the surface if you are concerned about cracking.I absolutely want to make them aesthetic, that's an important factor for me.
