Not exactly cheap, but Mouser has them.

Yeah, it might seem so, but if shipping to EU, you have to add VAT and import tax. It's about 24% combined in my country. And shipping for 1 piece is at least $42, for 5 pcs $102.Jamco is cheaper $61:

Just a heads up if you do run only 2 COBs(vero or cxa) on an hlg185-1400...Jamco is cheaper $61:

Been looking at drivers for a while now...
So I just realized I can power three vero29 or cxa3070 cobs on the HLG-185H-C1400A right? So would bring relative cost down to $20/driver for each COB. If I got 10 would be $18 but only need 8. Close to the $15.5 each for 10+ of the PLP-60-48 driver that are only 1.3amp and 89% efficient.
So would need five for the 15 vero29s and if I replaced the LPC-60-1400 I am using ti drive the cxa3070s would be another two to drive the six 3k and one to drive the two 5k (can do two cause min voltage is 71v and would be 77v to 84v for two). I also could use a HLG-120H-C1400A to power two but it is more expensive than the 185H anyways. So looks like I will be smart and go with alk HLG-185H-C1400 drivers.
Anyone need 2 or more and I will ship to u when I get them to get cheaper price? Haha. Im cheap as fuk.
Good to know.Just a heads up if you do run only 2 COBs(vero or cxa) on an hlg185-1400...
The voltage might not be enough once dimmed below about 800ma.
My experience with the Alpines is that they are only good for cooling of the heatsink, not for stimulating the airflow in your growroom. You would be needing an external fan in both cases (5V or 12V) because you want the air in the room mixed up. Maybe.....if you have a very small growroom or growcloset, it could work. Well, if you have a spare ATX laying around, you could experiment with that to see what works for you. Before buying something. I wish I thought of that sooner, it would saved me a lot of money.I will leave it up to smarter people to determine if 5v is better than 12v. I know 5v cools enough but for me 12v makes more sense with the fans moving more air in the room.
I can attest to the inadequacy of a single alpine 11 fan, for room-circulation purposes, even at 12V. Definitely not enough, though it's certainly making a relevant contribution. It's 'somewhat' helpful, if you're not using a big gusty fan... or you could just use one big fan and not worry about that little bit shooting out the sides of the heat sink. (but it's still plenty enough to blast cann-a-roma Out of the box/room, when the door is open... which you probably don't want)My experience with the Alpines is that they are only good for cooling of the heatsink, not for stimulating the airflow in your growroom.

Jamco does not have HLG-185H-C1400A in stock. When I ordered it said 5 days ARO now says 7 weeks. The HLG-185H-C1400B shows what mine did when I ordered. Isnt that the external POT? I have to look it up again.
CS said will contact me to let me know lead time when she finds out.
Mouser has a couple HLG-185H-C1400Bs $10 more. Do not stock the A.
Where have others bought these from?
I only see 9 A and 5 B here for $5 more each

Ya, I have been going back and forth with it as seems to make more sense to power them at 5v and figure the rest out with other fans.My experience with the Alpines is that they are only good for cooling of the heatsink, not for stimulating the airflow in your growroom.

If you want more circulation in a small space, i recommend comparing flow versus power draw numbers, and strategically positioning the 'most efficient' fan you can find, near your passive intake vent(s). Still want it mostly passive, but giving it a little nudge just inside the vent, isn't the same as "forcing air into" the box. Comes in under neg pressure, then gets directed. Once the air casually meanders in, it's whisked away on an aromatic adventure, and eventually cleansed and returned from whence it came! (and if not, you're doin' it wrong)
If you wanted to get nuts, you could design a "cool tube" type thing, but for your heat sink. Intake from outside, exhaust to outside, all sealed, no leaks.
Consider the tendency of resin, in all its forms, to accumulate. Think of your favorite apparatus.
Can that same type of thing happen to a heat sink? Will the heat sink eventually lose cooling efficacy due to perpetual exposure to cann-a-roma? Does any of the sticky go airborne? Can the stink coat the heat sink to the point of compromised cooling capacity? Can anyone test the efficiency of identical heat sinks exposed to disparate levels of stank-film accumulation? Do we know the thermal characteristics of a sheen of cann-a-roma-resin covering a heat sink, after years of perpetual... service?
