Just recalling the phone conversation I had with them.

That's the one I was thinking of but this twist is much less.

No but is did the whole plant go like that?

Does meanwell make one same spec but for non haz location? I wasn't seeing anything close to the capability, seemed like they went to haz location at about 200w. But I was only searching one site.

That's (taking it to your buddy) not necessary but certainly easier than the method I use which is capable of getting down in the 1/1000 range. You want to get flatter get what's called a reference stone. You can also use a number of various diamond files specifically for flattening . For clairification flat and smooth are not the same thing.
Side note based on memory recall the artic hs I have were 15-20 thousandths concave with a feeler gauge

catching up on some old posts here
yes
they are not by default. IP65 enclosures is the default. they do make "explosion proof" ones for hazardous locations, but its a (prob super expensive) option
dont divide the 42V by 7, divide the 14.3A by 7 to get 2.04A. at 2.04A you might as well run the 36V version (16/7/8=2.08A)

Where this 14 amps from?

datasheet
HLG-600-36A = 16.7A
HLG-600-42A = 14.3A

I think one of us is smoking too much I think we're saying the same thing. the explosion proof would be the div 1 but I'm sayin the div 2 cert which is what the HLs are is also expensive to get while a Class II cert is a lesser cert like this one http://www.mouser.com/ds/2/260/OWA-60U-spec-806328.pdf

Everything is soldered. Electrical tape over any joints that were exposed. Cobs are wired in parallel. I did some work with audio electronics before my cob light days lol, so I'm pretty ok on my soldering/connections/routing.

I'd smoke you up if you were anywhere close to northern Colorado!

Soldering is way fun to do to me.

HLG-600, could run 8 cxb3590 36V chips on that, right? Each one gets about 75W? I'm still trying to work out the code, lol

So the less the #, the greater the "juice". Totally opposite from the "c" version most use from MeanWell.

Agreed and I feel like it's a more solid connection than the pico connectors or a lot of prefab ones.Soldering is way fun to do to me.

look at the bottom of the first page of the spec sheets it shows you the code, I cant remember it so I always have to look. but yes 8x75=600w

below 2.05ish A = 36V 'A' or 'B' version will work
2.05ish to 3.15ish A =36V 'A' version ok(as you need 36.1-37.8V adjustable via built-in pot, 'B' version is not adjustable voltage), 42V 'A' version ok
above 3.15ish A = need 42V 'A' version as you need to be able to adjust to 37.8-38.5V as required (36V 'A' version tops out at 37.8V adjustment, 42V 'A' version adjusts from 35.7 to 44.1V)
2.05ish to 3.15ish A =36V 'A' version ok(as you need 36.1-37.8V adjustable via built-in pot, 'B' version is not adjustable voltage), 42V 'A' version ok

2.05 x 36 = 73.8W, the B version runs 8% over when the dimming leads are open, would that help?

has anyone here ran one of these larger drivers this way yet? i dont like what you said about having to adjust volts to match cobs?sounds scary haha.
