Interesting, the reason I was asking is I'm looking at either water cooled lights, or Ice Boxes on three 1000W lamps in a sealed room with CO2. According to their equivalencies, that would be four induction lights, but I don't know if that is taking into account the fact that the ligths can be closer, uncooled or not. The cost ends up about the same after the water chiller for either lighting set up, but I want to be able to maintain 90F in the day (CO2 is most effective 90-95), 90 at night for the first two weeks of flower to minimize stretch, then cold snap the last week or two to bring out color and more resin...the first grow i did i did not trim anything. the second grow I actually brought everything out and did trim off the bottom 1/3 or so I thought, just didn't really go back through for a second pass and probably wasn't aggressive enough but if you go back into my posts a few pages there are pictures of the before and after. Even with the trim the middle of these plants is very light, but the density on the tops is amazing really. Just as good as what I experienced with my 1000W HPS, I think that once you give the plant enough light, it comes down to genetics and CO2 enrichment for the truly dense nugs.
Do you think these lights will be able to raise the ambient temp to 90? I'd assume yes, but I know HPS can... I'm also water cooling four reservoirs and the AC (filter, Ice Box, fan, defuser - circulation, cooling, and eliminating smell leaks). I'd rather not have that much water under pressure near my lights, and that's a good deal of extra weight, so it kind of depends on how many induction lamps I would need to replace it... Also, ambient temp is around or over 100 for 3 months a year or so - I was going to have the water chiller in the room outside the tent, and an AC in the window set to 75F to provide a layer of normal heat between the tent and the wall, and probably make it easier to regulate the internal tent temp as well, while removing heat from the water chiller from the room...
CO2 generator will also be water cooled... And the tent 10'x5, though the tables only 4'x8'.
Sorry about that, I've just had these lights bouncing around the back of my mind, comparing and contrasting the same things, since I first saw them... Maybe you can shed a little light on things... :X
