Lighting liquid cooled cobs.....

[BigSm0]

I like the how the heat is used part. Besides that traditional pin fins with a slight breeze is adequate. Even within some of my tests at double the recommended wattages

Oh yeah they work well air cooled but they could work even better with chilled water.. Check out the Cree datasheets referencing temperature and lumen output correlations

I enjoy how the heat isn't in the grow room it saves on ac or exhausted air for a controlled climate closed room w C02 etc....

They can be built smaller with any angle configuration too

Like a scrog grid with cobs firing from under the canopy up ....

Just got a gang of cobs......20x clu048 1212s 5 @4000k 15x @3500k . I'll split it up between 4 3ft light bars in a 4x8ft tent and run 1000-1400w. It looks like I can hit about 110%+ lumen output if I chill them down low.

700w

Couple more shots of the lights in action and plumbing.

I'm going to build 2more bars for 4 total .then either I split the 20 1212s up or add 20 more cobs then split the power for high efficiency.......a guy can dream anyways

Just ordered 20 more 1212s 5pcs 3000k 15pcs 3500k it will bring my total to 40 cobs @ 700w total in a 4x8 tent..... Thinking of ir far red and uv additions next

Ive been doing it this way for years now...its cheaper for heat sinks. And just makes a ton of sense when u start playing with all the numbers involved w heat transfer etc.im thinking of selling them in a more refined form. Im going to do a diy addition as i build the next ones.
