Well, I like his description of everything in the video alot better than a single graph.Thank you i got it now so i have to refer to this graph ? :

i hear this but dont see it in practice. youd have to run them pretty hard to even get within 10% of the 3590s.No doubt the cobs can handle that power, but defeats the point of using cobs IMO, since efficiency is reduced so much.
View attachment 3600267 The CD bin CXB3590 is under 50% efficient at 2.1A, and just over 43% efficient at 2.8A.
At those driver currents might as well use the Vero 29 V2.0 as they about the same efficiency at those high drive currents and half the price, and dont require mounting brackets
You are right, not as close at the higher currents as I had rememberedi hear this but dont see it in practice. youd have to run them pretty hard to even get within 10% of the 3590s.
at typical "high currents" (for us) of 2.1-2.4A the 3590 is about 15% more efficient
not that the veros arent a bargain (85-90% of performance at half the price), but the 'about the same' might be a stretch

4 cobs on a 320 is 80W each and is prob better. wayyyy more efficient than running them over 100WI want to purchase 3590's CXB 90 CRI 3000K cobs, how could I drive the lights to 500 W per 4 cobs? What drivers are stable enough to do this? Im planning to use CPU coolers with fans on each cob because it will be cheaper than buying 36" heatsinks from HeatsinkUSA because of the duty fees and currency exchange.
That's why some run Vero's hot where they are equal in efficiency with the CXB's. 125w and up it's basically dead even. The 4000k Vero 29 @3150ma gets 123lm/w. The CXB is about 129lm/w. Splitting hairs at higher currents but the Vero gets a slight win because you can buy more for same amount of money.You are right, not as close at the higher currents as I had remembered
That's a tricky question. It will be close, I'd have my money on C1750.Umm.. would elg-150h-c2100 or elg-150h -c1750 end up with higher lumen output on 2 cxb3070 3500K BB?
and bunus question approx how many ballasts can you run on one 240V line/?
BonjourCan 4 - 50W Vero29 4000K 80 CRI cobs successfully cover a 4x4 space?
You probably won't get full power with this driver (too low voltage).Ok folks, so Ive come to a point where Im ready to buy my cobs and my power supplies. But i need help deciding which driver is best suited for my needs. Ive decided I want to make 8 cob bars with 4 cobs each, driven at 75W per cob (300W per bar) and have 4 CPU fans per bar (1 per cob). Im buying the Vero29 V2 4000K 80 CRI bins. Im looking into buying 8 of these drivers http://ca.mouser.com/ProductDetail/Mean-Well/HLG-320H-36B/?qs=sGAEpiMZZMt5PRBMPTWcaRTgZe1UVjfleDe6SlkiSzg=
Will I be able to drive each bar at 300W and power 4 CPU fans on this 320W driver?
NP problem thanks for pointing it out. I want to help ppl make the best decision, but I dont know everything, and more info is always better bro!hey bassman just a shoutout i love your posts man, always very informative
108 CAD? or USD?i wouldnt plan on running the fans off the driver, get a separate little 12V or whatever power supply for that. the driver at full power will run your cobs at 80W. im literally doing the exact same setup here soon with cxb3590s
btw, thats a ripoff for that driver. everyone else (TRC, sager, onlinecomponents, etc) sell it for about $108:

That's the problem with Vero 29's. Running 4 off one driver leaves you little in terms of choices. If you ran 3, 5 or 6 everything would be much easier. Running 4 cobs is a perfect match for Cree. If you ran them at 50w each the HLG-185-1400 would be perfect. You'd probably have to order everything from Kingbrite though but the prices for Canadians at Cutter are pretty reasonable too. You could also run the Vero's at 50w each with an HLG-240-1400 so there's that option too.Ok folks, so Ive come to a point where Im ready to buy my cobs and my power supplies.

The prices you saw in his link were Cdn. A $108usd driver will be around $160-$170 once you hit it with the exchange rate and shipping/duty. Here's the deal for us Canadians. If we pay $45usd for a Cree, then shipping/tax say it works out to $60usd per cob. That's at least $80cdn for one Cree cob. We can order Vero 29's for $37cdn per cob and it ships from here in Canada for next to nothing. It's hard to justify buying Cree for us in the current state of the economy/exhange rate.btw, thats a ripoff for that driver. everyone else (TRC, sager, onlinecomponents, etc) sell it for about $108:
