I'm curious what the mistake was, specifically. Kinda makes me nervousSo I had a cob burn out due to improper mounting. Got a little carried away with the replacement. Wanted to see if I could cool this with the heatsink I had.none are running over 20 watts ATM.
It's really bright though. You can barely see the light my blurple light puts out lol.

Didn't mount it well enough to the heat sink so half of it popped off and burnt out.
Thanks bass. Was waiting on a bigger build so I had the brand new cobs sitting around. Doing some spectrum experimentation figure they're more likely to mix close together. Plus, just means I can buy better cobs for my bigger build lol. I do have some of the 90 cri cxbs in there right now. The spectrum was too tempting.
I have several different cobs here, so I will never know which is responsible or not for the outcome from my grows.
Well I now have them more or less clustered and have
I have all 80 cri cobs
That's a good amount of sources lol. I bet yours are more spread out than mine lol.
I have cobs on 8"x8" Heatsinks. Right now a pair per heatsink, but I am going to redo it soon and might change it
.375" or 9.5mm
I ran 2 passive for a whole day by accident as I forgot to add a fan on it.
Nice pic! I notice the legacy HID sockets hanging on the side. After discovering DIY COBing, my HID fixtures are now gathering dust as well. So please clarify a few details of your build. So you have 5” pieces of the 4.9” HSUSA heatsink, with a CXB3590 on each one driven at 50 watts. I am assuming you have a fan on each one? A picture of the top would really help. I like to see how other guys put their light bars together. Also, as a side question, please explain your watering scheme. Thanks.
