You are talking about the liquid cooled light fixture right? I have seen alot of people talking about how there is virtually no heat, which is pretty cool. I also saw a couple people say it reduces the lumens after they pass through the water some how. You would also need a water chilling machine so your water doesnt heat up after passing through the light that many times. for the money and inconvenience of extra pumps, chillers, and water tanks one should probly get a good ventilation system. seems there is no discrepancy in the quality of air cooled.any body know anything about this product line looks pretty cool in theroy are there any down sides? besides more electricity and possible rise in humideity it looks like it can do the job well if u know any thing put it
