water cooled LED

Possible with copper, yes. Doubt I would advise it though.
If you want to DIY theres a nice thread around here on making your own light bars out of rectangular aluminum tubing. Much cheaper and easier to work with.
Otherwise I would just go the CPU water block route. This is easy as pretty much everything is "plug and play".
The real question is whether or not your situation would really benefit from water cooling over a more traditional route?
OK. cool. But water would be much easier.
That set up is not great. At least not for me. Since I want the heat to transfer to outside with the water. In that set up water cool the light but air cool the water.
Pretty much. All the mineral oil is doing is serving as any other passive heatsink would. But likely faaar less efficient at transfering its heat to the environment.

Yeah,wouldn't require buying a bunch of mineral oil. Just get some square aluminum tubing about the same width as the COBs, stick em on and pump water through it. Might be a little tricky to attach a round hose to a square tube but I'm sure it's possible somehow. You don't need to buy the big COBs, they have smaller models. You just use more of them.

Yeah true. The video says "experiment" anyway. Besides, it would be heavy as hell.
Yeah, Im typically of the belief that people usually over play dangers in a grow room, but something about those mason jars filled with liquid dangling from the ceiling with a light inside rubs me the wrong way. Maybe Im the one over playing the danger this time lol.

I would also recommend using PEG instead of water. It won't make steam or anything due to high boiling point. That's what they use in industrial building heating systems. Don't know if it conducts electricity, probably not. At least I think it's PEG, that a closely related glycol.
If you plan on making custom light bars rather than off the shelf PC cooling water blocks, refer to below.

How do you plan on cooling the water? Radiator, passive, or active chill?

Th
edit- not the same as the above post^^, These were longer pipes with no electronics, fans etc..
There's a video, I think somewhere in the middle of the "post your diy pics" thread, where someone uses square aluminum pipes and mounts cobs directly to that, and using 55 gallon drums to cool the water. It was a fairly big system iirc.

In winter: Pipes in floor of house will heat the house + excess heat to pond outside if needed. In summer will be more tricky. But pond will work.
I am thinking copper only because most water pipes in the store is copper.
The reason I want water cooling. 1. I want a sealed room = no heat exhaust. 2. AC need too much electricity. 3. Cold winter here. Will be easy to cool water. 4. No heat signature did flar.
Steam will not be a problem. Water temp. Should be about 25 degree Celsius. With controlled system and water reservoir.

Yeah I guess you're right, no pressure would ever build up at those temps why why buy PEG when plain old water will do. Good luck with it, however you end up designing it.
Yes, exactly. I will probably use some AC in summer + grow less in summer. Makes sense and look good for seasonal power usage. I can heat house with no cost in winter and have a good excuse to high power usage = will say heat house with electricity.
That is great. Its kind of how I was thinking from beginning. Cooper pipe is standard for water. But I plan to use more LED and longer pipes.
