Thanks Bassman for your answere. So it barely fits the max voltage of the Driver.
Any thoughts about the 2 coolers? Alpine 11 or 64?
It looks like the holes on the Alpine 11 could be handy to mount the cooler on the profile.
And most of you DIYer are using the Alpine 11 Plus. So it "must" be good

I have seen both used, I dont have first hand experience with either though.Thanks Bassman for your answere. So it barely fits the max voltage of the Driver.

This is what I used to determine that this driver works
where is Isles ?

alpine are rated to dissapte between 65 and 95w of heat depending on the modelThanks Bassman for your answere. So it barely fits the max voltage of the Driver.

we run cobs at about 50w so around 20-30w of heat depending on cob/driver combo
any of the cpu coolers will work fine- i use the arctic alpine 11 gt for 50w running the fan at 5v no worries
others use the 11 plus- it depends on the cob holder u will use so what size base u need
anyway why dont u post questions i threads for questions and leave this one for mouse to show us his awesome build skills?

also for 3590 with holder use alpine 64 plus
Chiming in here...
"cxb3590 ( 36v ) CD 3500K @ 700ma"
Why 700ma? I did my calculations about the CXB3590 and think it's "best" to run them at approx. 1650ma-1700ma.
Wouldn't running them at 700ma be a waste because you need way more chips for the same amount of light?
(On the other hand I won't deny that over time it's more economic to run them with as low amps as possible...but 700ma still seems low to me.)
I am sure this has been addressed in this thread already, just didn't have time to go through this entire thread.
PS. stupid question...all that DIY wouldn't be a problem for me..:EXCEPT the drilling of holes in the heatsinks. Can anyone recommend what type of drills/tools are required..this is the only reason I am still shying away from DIY..the mechanical stuff and requirement for special tools.

the higher efficiency of running cobs at lower currents is well worthwhile. Its a property for leds (lower cuurent, higher efficiency, lower temps, higher light output, etc). Each person needs to identify their own sweet spot for efficiency versus cob cost.

Agreed.
I'd like to add that many have found the 200W driver pushing 4 Cree CXB3590 chips at 50W apiece to get 56% efficiency to be their sweet spot, and if you're unsure I'd say that going with this combo will not steer you wrong.
lol my sweet spot is 5x cxb3070 on the hlg-185H-c1050. compare the hardware cost versus the light output.
who what me you ?

Northern Tool has a drill press on sale for $60. Probably similar at other tool places.

No sorry, I answered a question that had already been answered several times.
Which would be the 36V COBs running at 1400ma, right?

...or the 72V versions, running at 700mA. The two perform the same, the choice helps builders better match drivers.
