Worthy mention. As with anything you should always understand the risks of the DIY approach.

ELG drivers do too. When you dim a B version under 10%, they go to 0%.Fun fact!
the HLG-600H is the ONLY meanwell dimmable driver i know of that dims all the way to zero.... not even the 320H does that.
Dimming and remote power
Haven't had a chance to hook mine up and play with it yet. However from the data sheet the 5vsb line is supposed to be able to provide 5v@500ma.so RC is a make or break closed circuit?
what is the spec on the 5V dimming, 0-5V for 0-100% brightness?
These are truly 350 watt drivers. Just as the 240 is 250, 120 is 125 and the 185 is 200.You might want to go with the HLG320H-C1400 and run 8 COBs. This way you can build 2 fixtures and at 320 watts each. You can still make it a remote driver. CDIweb has a few here https://led.cdiweb.com/ProductDetail/HLG320HC1400B-Mean-Well-USA/593952/
what? there are dozens of choices. they make a dozen 48V constant voltage drivers that can drive these up to 3A+I have been curious about the driver options for this chip as well. There are obviously very few choices right now as far as meanwell goes
it doesnt work like that. you *want* your driver voltage to be more than your cob voltage at a given currentThe first example is running 2 058's off an HLG-240-C2100, whic could run them up to 125w each which is supposed to be still in the 160lpw range if I remember correctly. Would be nice, but the voltage turned all the way up is 119vDC which is 3.5vdc over the max voltahge for 2 of these chips, at 56v max a piece.

You are right, I suppose there are many single cob driver options, or paralell options, which is really probably a better way to go for these anyways. Might be a turnoff for some diyer's as wiring starts to get more complicated, and dimming must now be done per led, instead of being able to dim the entire panel.what? there are dozens of choices. they make a dozen 48V constant voltage drivers that can drive these up to 3A+
and any of the regular constant current drivers like hlg-185h,240h, 320h all work fine.
What I dont understand is how you can, or why you "want" to go over voltage they clearly state on the spec sheet that 56v is the max voltage. In what case would you want to be running at 59, 60v etc. I thought that was the whole point of matching drivers to cob's, was to match the max voltage to number and type of cob's so you wouldnt end up blowing them out by going over voltage.it doesnt work like that. you *want* your driver voltage to be more than your cob voltage at a given current
Okay so the A version can run at 350+w, although I cant find that 1.63 max current anywhere on that datasheet, but i'll take your word for it. its a long sheet. Good to know. Thankshttp://www.meanwell.com/product/led/LED.html > click on HLG-320h-c > click on "REPORT" tab>select 1400mA
max current = 1.63A (note you might need 'A' version to do that - seems that B version tops out at 1.4A with dimmer leads open)
I thought it did but after a few people explaining to look at the data sheet too, it looks like it's 320. Just thought it was stupid that it doesnt follow the same pattern as all the rest. Hlg120=125/hlg185=200/hlg240=250. But I guess hlg320=320 this time.I have been curious about the driver options for this chip as well. There are obviously very few choices right now as far as meanwell goes, but I have notice this tiwce now with suggested drivers. The first example is running 2 058's off an HLG-240-C2100, whic could run them up to 125w each which is supposed to be still in the 160lpw range if I remember correctly. Would be nice, but the voltage turned all the way up is 119vDC which is 3.5vdc over the max voltahge for 2 of these chips, at 56v max a piece. The second example @nevergoodenuf listed where you use 4 on the HLG-320H-C1400, again, turned all the way up, the wattage is fine, but again we are going over the max listed voltage of 56v. only by 1.15v in this case, but still, I would be worried to run it at full power, and I would imagine wiring in a small resistor to your potentiometer circuit would need to be standard practice to prevent going over voltage with these drivers, but that would also limit your wattage, also making the HLG-240-C2100A especially, but also HLG-320H-C1400A not an option for people trying to keep it simple, and skip the soldering, extra circuits, parts, and now resistors.
@Airwalker16 are you absolutely sure the HLG-320H-C1400 spits out 350w? it is rated at 320.6w according to the meanwell datasheet. I know the model numbers dont match the wattage, the HLG120HC1400s is rated at 151.2w, and is actually a decent option for 2 058's at ~75w a piece. no over voltage, as the max is 108, which is perfect. 185's is listed 200w, and 240's 250w, but I have also heard that some meanwells put out more than they are rated for, by a significant amount sometimes. I have heard of an extra 20w on the output side, and as much as 53w on the input using a kill a watt, and we would expect extra draw on the input as these drivers are "only" 94-95.5% efficient, but having said that, an extra 53w at the input of a 240 running at 94% means it is definitely pushing more than 250w.
I like the HLG-600H-54 for these chips. It is the only driver I know of that would really give you a full set of options for how hard to drive these monster cob's, as you could run anywhere from 2 058's at 300w a piece, all the way up to 12, at 50w a piece, or more if one were so inclined, and anywhere in between. Plus you can always add or remove a cob or 2 to either improve efficiency, or run em harder. the only downside is running them in parallel, but with a chip that can handle 364w that is hardly a concern if you are running 3 or more cobs on this driver. If you were crazy enough to run them that hard and had either water cooling, or a fucking massive heatsink setup, you could still have one go out, and the other 2 would be fine at 300. but if you are running 5 or 6, or more, which would be a little more realistic, you could have half your cob's go out all at once, and still be within range. The heat may be an issue, but its entirely unlikely that anyone's going to loose half their cobs, before noticing, on an assembled working fixuture anyways. there is plenty of room for people to blow out lots, or all their cob's in the building process, But that goes for any diy'er building any sort of cob fixture.
agreed, but even the 320 is not always 320w. the 700ma version is 299, and some of the other lower current ones are as well. But at 234v * 1.63A =381.42w so if the A model can really push 1.63 thats damn near 400w. no wonder people are finding more watts than they paid forI thought it did but after a few people explaining to look at the data sheet too, it looks like it's 320. Just thought it was stupid that it doesnt follow the same pattern as all the rest. Hlg120=125/hlg185=200/hlg240=250. But I guess hlg320=320 this time.
Ya that's very interesting. That's a B model with dim leads capped off I thought? And where is 1.63 comin from? It's 1.4 then 1.75 next.agreed, but even the 320 is not always 320w. the 700ma version is 299, and some of the other lower current ones are as well.

75 is aYa that's very interesting. That's a B model with dim leads capped off I thought? And where is 1.63 comin from? It's 1.4 then 1.75 next.
But the best I can find is on page 2 "Output function test" scroll down to line item 4, and althought the spec says 700ma-1400ma but the result of their test appears to be 0.561A-1.629A. That is the best info I can find on the subject. I am curious if that is where @CobKits came up with the 1.63A. I dont see anywhere else on that sheet where it mentions anything above the 1.4a spec. so I'm guessing thats what we are talking about. I am also curious why it would only be the A version that could reach that. the numbers appear to be the result of the adjustment rangemax current = 1.63A
It would explain the extra 8% output if you cap the dimming leads.75 is a
1.75 is a different driver. Higher amps, lower voltage.
it sounds like your looking at the HLG-320h-C-all models sheet @CobKits linked to. from that page Up at the top you need to click -> Report -> HLG320h-C1400 click on that and it should bring up the test report sheet for the 1.4A 320w spec driver. I have had some trouble finding any place where it says

That's what I thought. I remember seeing you get the very highest output by using B model with capped dim leads.It would explain the extra 8% output if you cap the dimming leads.
