So happy right now. I had almost given up on something having knocked loose but I just found the loose wire and now my light works again. I really appreciate all the time you've taken to help me out tonight. I was so worried I fucked up my just built light. Thank you all so much.

Ahh, that makes sense. So with that power supply I'll just need to buy a power cord for it right, then just hook it up using the wire I already have to the ideal holders and I'll see which works.

That thing runs 0-15A what amperage would I run that at?

That's good to know, I'll check those out. Thank god for Amazon. I'll check that all the screws are at the 4.5lb/in and go from there. Thank you for your help, I really appreciate it. I wanted to cry when I saw my brand new light go out

What would testing with an appropriate power source entail? Find a 36v power cord and plug it directly into the holder? Or would I need the 7-18v?

I did, do I need to pull it all off or could I just make sure that all the screws are at 4.5 lb/in? Is it more likely that something is just loose rather than I broke a cob from the shock of the fall?

it didn't register anything when I attached them to the wires coming off the holders, maybe the holder isn't tight on after the fall. 36v each cob 180v in the series

Apologies, after looking online I was saying continuity but it appears it's a diode mode, it's what I used to check my mars lights out before. The thermal grease stays liquidy so it'll come off still right?

Any idea how to troubleshoot what's wrong then? Id at least like to know which cobs still work so if need be I can replace one or two instead of all 5.

I got the wires out, stuck the multimeter in the wire holes and it doesn't show anything just the default 1 it shows in continuity mode. Also tried connecting to the end of the two wires going into a cob from the other ends and still no reading at all.

Are the second holes smaller than the primary holes on the holder? I tried sticking my multimeter prongs in the second set of wire holes but it didnt do anything. I look for that video now, ty.

I can't even get good contact to the cobs with my multimeter to do a continuity check to make sure they still work. Any help on how to even troubleshoot this light with the ideal holders on would be great.

My brand new cob light was sitting upright on its side while I was letting it run to make sure everything was wired correctly. As I got my final of 4 lights finished I went to set it up and let it run and see how bright all 4 together are. One of the lights fell over and just died. It still...

Good to know! I'd have kept on fucking with them, playing with the brightness lol.

Oh shit, that's pretty cool. I feel like I just got a way better value out of my lights. the DIY Cob Calc won't do 1.2A but for 20 clu048-1212 90cri 3500k cobs over 16ft at 1.28amps can I reasonable expect something like ~1200ppfd?

I have another question. I'm using an hlg 240 c1050a and running 5 clu048-1212's. the default setting on the driver ran 202w which is above the 180w I was expecting. However, as I was playing with the dimmer screw, I turned the lights up to 240w from the wall. Can I overdrive these cobs because...

not so much scared of getting shocked as fucking up my freshly built cherry popping DIY cob light. thanks for the help :)

Hello, I've got an A style meanwell driver with the internal dimming screw. I'm curious as to whether I can dim that driver while it has power flowing to it or if I need to unplug the driver to adjust the current without shocking myself or fucking the driver up. thanks for the help

What's that box above the driver? A light controller similar to a helios?

Are those plastic disconnects on the fans or lights? I bought some quick disconnects on Amazon and they don't disconnect, the male piece will just pull out of its insulation.
