I just wanted to pass this out. i was at my local hobby store when they walked it in. this unit is up and running you can put your and 2" from the bulb. this means you can 1k light your plants from 6 inches away cool to touch this unit removes almost all the heat. bye bye heat signature :mrgreen: Texas Hydroponics :: New Products :: Liquid Lumens "HydroFlector" Reflector Insert

of course this means you need a chiller but with this massive heat reduction you can put a few 1k lights in a very small area

Now Ive seen it all. Kick ass!

I recently switched to liquid cooling on my PC and was amazed by the diffrence from air I can only imagin the heat reduction that system will produce. :)

Watercooled lights are kick ass but they are expensive. A 1000 w hps will use about 100 gallons per day to cool the light. You have to recirculate the water which would require a big water tank. And it the tank has to be cooled. Just a little info I thought I might share...peace out

Ya Im curious as to that too. My PC just uses copper block and small radiator and is able to maintain 20 degree Celcius lower than traditonal fan on copper heatsink.

I wonder if you could use something like a car radiator and fan asymbly for the heat displacement.

It would have to be really clear water. You would have another batch of water to PH balance and do pool stuff to.

P.S. Im what you would call Geto Fabulous/Jimmy Rigger if I can make it myself I will.

there are at least 4 ways to liquid cool your lights. I use a
hydrocoil- the company went out of business a few years ago, but there are few places that still sell the coils. About $200 will get you a coil that will cool a 600 watt bulb, which is what I'm using to grow.
The main drawback to this type of cooling device is that it is somewhat fragile.
I use a simple wing reflector and about 10 gallons of water that is cooled using a 20 foot copper coil with a fan blowing over it- keeps the water about room temp. Totally self engineered, but it works great- you can also buy something called an ice probe that will cool your reservoir using a thing called and ice probe http://www.aquariumguys.com/iceprobe.html I am thinking about trying this out, but based on a 50 watt peltier plate, I'm guessing it would do the trick- or you could buy a bigger peltier plate and rig that up for yourself. Or you could buy a big peltier plate, a cpu cooling block, and a CPU cooling fan, mount the cold side to the cpu block and the hot side to the fan, then use a pump to cycle your water through the cpu block. This was something I mad scientisted when I was blazed one day, but I bet it would work. total cost would be around $100.

This is my first post here, but if I can figure out how to post pics, if you're interested, I can show you my setup.

100 gals a day? really? -rep to you.

That's cool, but I bet it's extremely lossy and grows inferior to a simpler cooltube. Two layers of glass plus water, plus whatever you put in the water to keep if from getting nasty.
Even if they use a mixture of glycerin and ethylene glycol as you would in a liquid cooled projector tube it's still lossy.


Abudsmoker do you have access to a light meter to see how it really does next time you're there?

A friend has a water cooled hood. He has a dorm frig that has two holes drilled in it. They passed hose into the frig and coiled about 50' feet in it. Then it returned to the light. It works great keeps the light cool to touch. I regularly see his bud touching the 1000hps reflector with no harm.

yes i have seen this before, probably good for major commercial ops, but the maintenance of having the tank recirculating on top of needing to chill the water...personally i dont like mixing water with electronics.....this is not feasable for our closet grows

I hear alot of people saying they dont like the idea of "mixing water with electrical".
But do these same people refrain from dropping an 80 watt water pump into nutrient
resevoir?? So whats the difference?

Does that mean having an everyday fish aquarium is totally irresponsible?

I have one and it works great. The only, and I mean only thing I am not 100% sure
about is actual lumen & spectrum loss. I would imagine 3/4 inch of water couldnt
possibly filter out too much good stuff. I run a 600w HPS, temp doesnt get above 78.8
degrees in a confined room, no heat exchanger. The Fresca Sol company has a product
called "No Flow / No Go" which shuts down light immediately if flow stops. So that
ammends that problem. All in all, it is an awesome product despite its cost.

hey tesuji, would love to see pics of your setup if you have them around.

also, great idea with the cpu cooling block, fan and peltier plate. how effective do you think this setup would be at cooling, say, 2 1kW bulbs. how big of a peltier plate do you think you would need?

would this setup also require a radiator? or is all of the cooling happening at the interface of the cpu block and the cold side of the petlier plate?

seems like a great diy that can save a bunch of cash. coolers are way up there in price.

thanks for your mad scientist ideas!

does anyone know how much water per hour per light is needed, and what temp the water should be
