Hello,
After posting previously about some ideas I had for a light and hearing back from people on this thread:
https://www.rollitup.org/t/2x-vero-29-cob-1000x-individual-diode-combination-request-advice-input.827033/#post-10477544
I've reconsidered my original plan and gone with something much simpler and more efficient.
I'd love to hear back and see once again, what I'm missing, or what I could optimize better.
My new plan is for a 10x Vero 13 (4k 80CRI), on a 12" x 12" aluminum plate.
Parts:
1x HLG-185H-C500A $75
10x Vero 13 $8x10
12" x 12" x 1/8th" Aluminum Plate $17
6x 3" x 3" x 2" Copper CPU heatpipe coolers $40 (6 used heatpipe coolers I bought off ebay)

Fan arrangement: unsure
I'd like to run the Vero 13's at 500ma.
According to the datasheet, this will put the VF at 32.5V, the Wattage at 16.3W, and the output at 2060 lumens, assuming a Tj of 25C.
I plan to arrange the Vero 13's in 2 rows of 5 (1.5" dia, 1.5"x7.5" per row) on one side of the plate,
and the heatsinks in 2 rows of 3 on the other side (3"x9") above the cobs.
I'll probably mount both the heatsinks and COB's with a thin bead of epoxy around the edges for strength and a thin layer of heatsink paste over the inner portion for heat transfer.
These heatsinks are for 125W Xeons CPU's, so I think it should be safe to say each would keep a 100W load under 60C, given the proper fan on top (standard 90mm CPU fan).
I'm probably going to build a shroud/tunnel around them and use a couple 120mm fans from the side.
If this is successful, I should have a 20,000 lumen led light at 163W+PSU losses.
Please let me know if you all think this is doable, especially with regards to keeping a Tj of 25-30C.
