It's so fun to build your own!!!
I suppose the gap is narrowing... Nine A51 W90's would be about $1,500. Tastyled's 1750 series, you'd need 3 of the 3 COB units to be similar, also about $1,500. Those are the only ones I can think of off the top of my head that are comparable to Jp's, because any maker that would put all 9 COBs in one compact housing is really screwing the pooch on coverage. You really need them spread out more than that.
I was more just saying you could get a similar PPFD, similar efficiency, for alot less, like 200 or 300 less
building it compared to mine.

Using veros or CXB3070s. And actively cooling smaller heatsinks.
4. I personally have 2 4row sets each on their own 240h-c1750b.
Hell ya. Glad to see someone driving these hard like that. 2100 MA FTW.Been awhile thought I'd update with my new clone/veg tent. Tried out a new design on a veg light.
2 - 120h / 1050 MW
4 - 72 v cxb3590 5000k
3 - heatsinks hooked with custom hinges
Should be pushing about 300w. The tomatoes and Denver Diesel are in heaven.
Working on the big flower panels now, and I'm obviously on a schedule now. Also just popped some new bodhi boysenberry hashplant last night.
Test run with the cxbs should be quite nice

They are actually being run at 1050ma. But with the 72v COBs they push about 75w/chip
Also for anyone using the EGRAF, you may want to think yet about using it with the 72v chips on a passive build. Sinks are running a bit hot. Had to add a fan :/ worth it for 300w but not what I was trying to build.They are actually being run at 1050ma. But with the 72v COBs they push about 75w/chip
