Ok, but what about those ebay? Where does that cobkits.com shop ship from?
Horticulture lighting group 550 light I found someone selling for 949.00 new on eBay and bought one it a great light Im very happy with it.LIST OF LED COMPANIES w/ LINKS
For people just getting into the LED game figuring out which company makes what light can be a challenge. This is a list of the companies and the name(s) of the panel(s) they make.
Lighthouse Hydro - Blackstar

Hydro Grow LED - Penetrator
Grow LED Hydro - Spectra
Kessil - Kessil H150/H350
Magnum LED - Magnum LED
Blackdog - BDxxxx/Platinum XL
Pro Source LED - Pro Source LED
Haight Solid State LED - Haight SS LED

There a retailer of hlg they had like ten others I think if anyone wants to save on the light.
cxb3590 are just one of many decent cobs. most fixture manufacturers these days selling them are selling them for the brand recognition not the price/performance
I just watched "growmou5" video on his grow, where he used, as i understand, 32 these COBs. So he writes that it uses 850w all together, I dont understand it now, because datasheet says, that one 36V LED takes 2400mah, that is 2.4 amps, right? So whats the power formula? Power = voltage x amperege, right? So 2.4 x 36V = 86 watts and 32 COB would pull 2.7kw from the wall?????
I will, but shortly - Is it possible by using dimmable drivers? And you just measure amps inserting ampmeter between COB and driver, then adjust your dimmer OR just driver is so selected, than LED jus get your mentioned amps? Every LED is more efficient at lower current... that made me think a lot.. It is based on info in datasheet, right?
Arrow Electronics... they have same product mix as Mouser. Have best price on Mean Well products and best of all free overnight shipping. You order it in the morning and it will be on your porch the next day. The minimum is only $20 and unlike Mouser I have not had to pay any sales tax.
I get the most out of my Cree CXB running 40 to 46 watts per COB during vegetation. I use the Mean Well HLG-320H-36A. The A designates that the unit has a built in dimmer...actually two, one for fine adjustment and the other for coarse adj. If you move plants around as much as I do setting up a parallel system makes more sense than running the LEDs in a series setup.
Just so you know. The A type CV drivers have a IO and VO adjustment. The VO is maximum voltage. This is not for dimming. Let the light run until like his stabilization (doesn't get any warmer) then adjust this down until the light starts to use less per then adjust back up carefully until you have full power. This will help stop thermal runaway.
You can use the 36 volt version.
So, the amperege range would be nicer, right?
Yes and it would still fit the driver. CXB 3590 it's under 36 volts at 1.4 so you will be good.
