Which light is better for coolness?

I don't plan on getting this light any time soon but I usually don't ask questions or get into something unless I have serious plans for it. My current grow room is way too small for something like this but one day I want to increase my wattage to help increase my yield. My first question is how many grams (or ounces, doesn't matter) do you guys think I could get with a 600 watter? Also which would be better to keep my plants closer? this one, or this? Now for people who are gonna quickly say the cooltube I would have to agree, but I made this thread because I plan on getting the AC Kit and Glass for the second light. Reason why I'm asking all this is because I don't know how well the cool tubes reflect light but I know lights with a reflective hood does a good job. So if I can get the same temps with the air cool options for the second light I will plan on getting that instead of the cooltube. What do you guys think? Am I confusing or what? lol

Alright mate:thumbsup:I will throw my ten cents worth here lol.The second light with the glass would be better if you have the right fan,compaired to the cool tube i found that they give better light intensity derected towards the plants and are exellent for scrog and sea of green but if plants are grown normaly they dont do as good as the cool tube as they can be hung in all sorts of angles which is great help when growing monsters.What method of growing are you planning?the postman.

Probably just normal trees if not topped or LSTed. I might try ScroG a few times but I don't know, it depends on if I have enough space.

Excuse my shitty artwork - this picture is pretty bad, but tries to explain why I like the cooltube for my current space - especially when growing different strains. The tall plants can be placed on the backside of the cooltube, to extend up past the tube. This keeps the light closer to more of the plant, lower budsites get much more intense light, and if your reflector is designed right (I made mine), the plant can actually be taller than the tube. With the standard light hood, imagine how much farther up the light would have to be to be above this plant. Not to mention everything else has to be on stilts then!

If you are doing a scrog or sog, or something where you will have an even canopy, the other style of hood properly cooled, will work better than a cooltube IMHO. A much more concentrated footprint
