water cooled lights?

seen these when i was looking at reflectors and i was thinking of grabbin a pair of these... i mean if it does what it says u could put yr 1000w twice as close 2 your plants atleast witch would highly increase any yeild..


* Water-cooling allows placement of lighting as close as 6” above plants instead of 18” to 24” with air-cooled systems — resulting in 9 to 16 times more light for your plants!

whats your thoughts?

Just remember, regardless of how cool the light is running. you still have to watch out for light bleaching. You can only get a light so close before you're doing more harm than good, savvy?

They have one of these at my local hydro store and it's pretty impressive to hold your hand on the glass of a 1k light and it's just warm. They also have a 50 gal drum of water to cool it which would certainly add complexity to the grow. The next thing that comes to mind is the reflector quality is going to drop lots because tubes are already plagued with poor reflectors and it now has to go through 2 pieces of glass and water as well. Also, dropping a 1k light down to 6" over the canopy is going to reduce the foot print of the light quite a bit so if you are trying to light a 4 X 4 grow, you will lose lots of light at the top outside boarder of you canopy. One application those lights would rock in is a small sealed stealth cab with co2 because they do really keep the heat down to a reasonable level without the need for a noisy centrifugal fan.

i think only where heat is an constant issue, say you had an attic grow, that this would be worth it, have to admit they are pretty fucking cool though

They had this technology and product-type around a decade ago in Canada; it went nowhere and disappeared fast. The product literature states that you need a 50-gallon reservoir for each 1000-watt.

It looks nice,and probably works well. But anytime there is that much electricity and power in one confined area......water is supposed to be far away...IMO

well if u consider that they dont give off much heat would be alot eazier 2 controll the temps in your room and even if u dont want 2 bring it down 2 6'' still having it a little closer+low heat.. will help with room temps as well as keep down the heat so the leo cant see your grow with their flair camras.. i know their is many other ways 2 avoid it with normals hoods but im just saying..

and its not 2 hard 2 fill up gallons of water

yep
just wait till the seals wear out

The seal on these $500 w/c reflectors isn't going to wear out. It's designed for the use.

I used to work a lot on computers and build water-cooled computers (as a novelty) which would sound like most people to be a very bad idea. As long as you know what you're doing... it's relatively safe.

But to be honest, I still wouldn't do it. I don't know where people are getting 18-24 inches from. I have my A/C on low and a 6" fan w/ carbon scrubber on 30% speed cooling. Yet when I touch the glass on my reflector, it's pleasantly warm, and definitely not hot. I can get my HPS 8-12" away, but the light bleaching thing starts. I keep it 12"+ off now just to increase to foot print a little, not because of temperatures.

You don't need water-cooling for these lights. Just an A/C. If you run all this water cooling, you're still going to need a water chiller! There's just no way around it.

 

[fear.loathingSF]

Water absorbs the heat from the light, so you end up with a bunch of hot water? Are these systems setup to waste a shit ton of water, or is water recycled with a chiller or something. A chiller would boost electricity use quite a bit...

The concept sounds very cool but it seems to be accompanied with some fairly annoying drawbacks

Aerohead said it best!

Above-ground swimming pool and water pump sounds pretty cheap? and you get a heated pool to enjoy....

Yep that's what I was thinking too, add one of those Hydrologic HydroGen Co2 generators, maybe even a water-cooled AC and I could keep ANY pool hot in any climate year round, just running a couple good sized pumps is all you'd need for cooling.
