A Mean Well HLG-185H-36* would suit this perfectly, best practice is to wire the COBs parallel with small value resistors off the negative side, but many leave the Rs off.
The stock Vf for CXB3590s is 36Vf, I believe, so that's not running them hard at all unless they're allowed to get over 55C. They are rated to a max of 39Vf at 4A (156w) although that would be expected to knock their lifespan down considerably.
Most DIYers seem to run 50W or under on the CXB3590, to take advantage of the efficiency gains in the nether regions.
There are no real reason to under-volt COB LEDs, IME.
Well, yeah. The plants might not care how much electricity I use, but my wallet sure as hell does. And multiple cobs running at lower power spreads light more evenly of course.
Just a pain in the ass. It's under a rubber stopper and it's done by screwdriver. B VERSION you just wire a potentiometer and a resistor to the blue and white wire. Done. Get a B version or you'll regret it.
you make a good argument for the veros indeed- cree doesn't perform like that at higher current(or perhaps I should say vero doesnt perform as well at lower current)
You need to drop 15v still. The lights would survive otherwise but not repeatedly day in day out. There are ways to drop it cheaply. You could use a 10.7 ohm resistor in series with your LEDs. Thatd be if running from 87v. Increase the resostance if you increased that drivers output. The resistor would need to be a minimum of 21watts, which isnt a stock value and neither is the 10.7ohms. Id bump it to 25 watts or get creative with low resistance-high powered resistors to add up to 21 watts and 10.7ohms.
LEDs will have "off" sections if under volted. It'll make ya think ya broke them haha
You are right, Cree doesn't perform like that at high currents, it performs a lot better. There is something very off with those Vero numbers.
A version is simpler the rubber stopper is no big deal all you need is a #0 phillips screwdriver. I run the A version and have made over 15 lights 16 to be exact.
to each his own. Try a b
You use a knob... it tells you whats up.
I don't understand this response. I was agreeing with you, and saying you can use a switch instead of a knob as well.
If it's not a money thing, you could add 3 or all 4 now, and easily run at a lower power until you expand. You can dim down to 10% with the B version, it's really not an issue, and you'd have good spread.
