The 140mm heatsinks are out. They are compatible with both Cree 3590 and Vero 29.
Website has 120mm heatsinks. There is an option for Cree 3590/Vero 29 and another option for only Cree 3070. All heatsinks are compatible with the Angelina reflector adapter.

I do not have COBs or Drivers on website. Just Photon 180 Lamps, Heatsink Kits and Reflector Kits.
International shipping on pin heatsinks is between $30 to $40 extra for 4 to 6 heatsinks. contact me for details.

Plenty of Pin heatsink threads already. I keep SST120 and SST140 designs from customers here
Sharing one of the coolest designs that a customer sent me. We may have a CAD drawing for this one soon.

I am getting ready to do a 18"x18" 4 cob unit using a HLG 240h C1750b drivers. The casing has a chrome like powder coating on it. Hoping to get it soon

SST X's have arrived!!!! Geeezus these sinks are beauties. I knew I should've just ordered 8 instead of four! Dammit, I'm gonna have to eventually redo all of my bars. @robincnn thank you for the pot j-box. It's gonna put my other two bars to shame, looking all good and professional and such. Just waiting on my hlg320-2100 to get here!

Also, thanks for the xtra wagos Now I have 2000 and 15 lol. There's a company here that sells them by the boxes. About 6 months ago i purchased two boxes of the older 221 version as well as the newer see thru lid versions. Only used 6 thus far.

Quick question. I have a build planned for a cabinet I have made. I had a thread about it here https://www.rollitup.org/t/led-diy-build-help.927250/ but did not get much activity. I was planning on using Two 44" 5.886 profileheat sinks to mount (4) cxb 3590's 36v per. Looking at this thread I am thinking about the SST120 or 140's instead. If I run them no stronger than 1400 mA which would be better. I will probably have them dimmed around 700 mA most of the time but I like the ability to turn them up. Another concern is how close could the heatsinks be to the top of a wooden cabinet? It seems they stay cooler than the 5.886 heatsinks, is that true?

For a height restricted cab I went with active cooling and wide angle bat wing-like beam pattern lenses. Quantum boards might even better solution though.
