Building a water cooled LED light

I started this on my normal Tank reached 38 years old...in 2009! thread or whatever it is called but decided to put it here because it may get complicated. I am building a water cooled, copper LED fixture for my 6' reef to replace my existing DIY air cooled fixture. Do I need a water cooled fixture? Of course not. But it is a fun build. This frame will have fresh water flowing through it by a pump and will circulate to a DIY radiator under the tank (that may be a car heater core) That very short copper pipe is not a through connection and is just soldered on the outside of the pipe for support. There will be 72 LEDs on here that I am taking from an existing broken LED fixture that my good friend at Aquarium Village gave me. I fixed that fixture but couldn't use it in that configuration so I am using it for parts.

This is the fixture I am taking the parts from.



I punched out and soldered on the 72 copper disks that will support the LEDs. Now (if I get time) I will clean it up more and shoot the entire thing with some clear coat because copper turns green and ugly. This way my Steam Punk look will last. But before I do that, I will make and solder on the supports for the plexiglass shield and also the supports to hang it over the tank. I am waiting for the thermal adhesive. I still have to either build or buy the heater core for the cooling.

Andy, now doesn't that fixture look a lot better now? This is the fixture of the future. At least in my house. Now I am going to make everything water cooled, my TV, radio, toaster, microwave and electric toothbrush.

That would be very cool. But harder to get than a car heater core. Unless of course you have one. I am not far from Merrick
