Grow room air to water cooling conversion project update
I Finally got the grow converted over to water cooling with the small lamp moved into the flower room along with the 60" lamp that is partially completed. I put the outside 3" bars on a temporary frame 12" apart with a thermal protection system and hung it over the grow table. This will give me a week or two to complete the center section and perhaps repair the 200 watt 12 volt power supply. When the center section is complete, I'll take an hour to bolt the outside tubes to it and hook up the cooling and thermal protection systems.
Here's a picture of the temporary arrangement with the two outside bars.

Another view of the large lamp, the outlet box mounted on the crossbar is in series with with the thermal protection system, composed of a 65C thermal fuse and a 40C thermal switch. I'll add a digital thermostat to shut down the complete system as another layer of protection, when I finish the build

Here is the small lamp in it's niche, it runs off of the same cooling system as the large lamp.

Here is a photo of the cooling system composed of a used 55 gallon plastic barrel and the cooler I made from the air cleaner and heater core. I have the 1/2" hoses from the lamps going into "T"s with 2 x 1/2" outlets and 1 x 3/4 " outlet. I have 3/4" ID hose coming from the pump to the inlet "T" and another "T" with a 3/4" ID hose going into the cooler, with another 3/4" ID hose from the cooler to the reservoir. The 24 watt centrifugal pump is in the bottom of the reservoir and is connected to the "T" at the top of the barrel with 4' of 3/4 " ID vinyl hose. The pump moves 9 liters a minute through the system and the lamps each have about 10' of inlet and outlet hoses leading to the "T"s located on top of the reservoir.

I made sure the table for the reservoir is strong and sturdy, since it has to support about a 500 pounds of static load.

I'm using about 60 US gallons in the reservoir, the 55 gallon mark is well below the water level, I figure there's about 230 liters in the system. You can get used barrels like these from a dairy or other industrial places for around $20 or even free.

Hi brother
just bought a very similar thing with 50w cob chinise pink
and I wanna ask you if you ever tried mixtures of cold-warm- and pink china-leds.
The pink must be around 1600-2000K they say but there are no PPFD values - so do you have any information about PPFD of these chinise full specs 380-780nm ?
And shouldn`t you open up a public pool with all the hot water produced every day ?
And a pully-warm coffee-shop with wintergarden and direct acess to the base ??
My watercooled is only 10% power of yours - but I can heat my bathtube every day i grow.
I copied some specifics from the shop- hope it is interesting for you.
to get more inspiration.
*** World first *** High-efficiency LED Plantgrow Aquarium Industrial Light
- Take advantage of the waste heat from your LED-Lighting for production of hot water.
- Ideal for greenhouses, larger aquariums, industry and always where hugh demand for light and heat join the same place.
~ 50-60% of the electrical energye can be used, recovered and stored in form of hot water.
In case of COOLMAC-300 - a total consumption of 290 watts lamp power
enables to rewinn 160 Watt stored as waste heat in the cooling water.
Operating the chips at temperatures just a bit above the room temperature means further efficiency gains of 5-15%
Different power levels (200-1200 watts) - The ability to select the desired spectrum of
10W, 30W or 50W chips offers endless combinations to customize the kit.
Design your own individual LED light with your own sizes. Length: 50cm - 150cm
Width: 10cm - 100cm
Height: 4cm - 10cm
With optical lenses or without - this LED lamp is endless - in terms of individuality.
The kit comes completely mounted but without connected drivers.
Buyer has to solder the chips and connect the drivers to the cable.
After all connections are done - the lamp has to be filled with water
and can get started.
Caution !!! Aluminium tends to be regarded as poisoning.
Don´t drink the cooling water and don`t use it for your plants.
It`s recommended to put anticorrosion in the watercircuit. (for aluminium coolers)
The best efficency in solution is to cool the circuit-water with aluminium-radiators.
Hanging them into cool ground-water that later needs less suplemental energy
for to be used by plants and human beings .
