Just ordered 250x Citizen CLU046-1212 units. 180 for flower (3500k), 30 for veg (5000k) and 40 more (3500k) to play with side lighting :)

Gonna have some fun with these things :D

@Will Thayer helped me out on sourcing. At £2.20 each after delivery and considering I already have suitable Meanwell HLG-600h drivers I had to jump on them. Thanks a lot!

I got some Samsungs I run 12 on an hlg 185 500c 146-154 lm/w. Super great heat dissipation and the holder is built in with pretty hearty wire clip in that you can utilize from two different angles. Really impressed with Samsung cobs

Bahahaha!!

Now I've completed a grow I plan on experimenting :)

I'm going to run 90x water cooled CLU046 COBs at 20w (36V @ 0.55A) each per 8x4 area. So 900w per 4x4... at around 1300 PPFD (may or may not be a little higher because I'm water cooling and so COB temps shouldn't be as high).

That is top lighting.

Then I'm going to add 8x CLU046 COBs at 20w each passively cooled as side lighting per 4x4 (2 COBs from each corner). That should give me an extra 270 PPFD under the canopy.

I wonder how much I could grow per 4x4? :D

I was planning on doing a Cree CXB upgrade which would have cost several thousand £££ but the Citizens make it sensible to just go ahead and do it now :)

A dollop of thermal glue... and tada! Worked perfectly for my current setup. The alternative would be kapton tape and thermal paste which is probably more fragile but would cool marginally better. Mounting COBs onto water blocks in any other way is difficult. You can't screw into a water block... :D

I will try. At the very least there will be pics of the finished setup.

I am interested in seeing the waterblocks.
My setup now is paste and kapton, but it starts to peel on some edges after a few grows, at least mine did

Wait... so you're gonna be using those like 2"x5" water blocks? That's gonna be a fuck load of gluing and water blocks. I'm very interested in how this is going to even work. When will it be complete?

I've ordered the bits tonight to make some improvements on my previous efforts. Should have it all in my hands this week (touch wood). Maybe I'll have 30x COBs on a 600w driver done by next weekend as a prototype? Maybe I won't. If I didn't have a day job I could probably have the whole setup complete in a week. Who knows? Not me!

My plan was originally to run the cheap chinese COBs as a test. See if the water cooling setup worked. Iron out any issues that crop up over the course of a few months. If it worked I was going to upgrade to CXB3590s. It would have been insane to spend thousands of £££ on a 3600w CXB setup when I hadn't even grown any weed before and didn't know if water cooling was feasable. The Citizens were just too good a deal to pass up so they're the new upgrade :)
