Yeah, I'm sure there are 220 volt units made as well. And as for the venting idea, it would be fine as long as you run a carbon filter setup before it gets into that vent. Either run a 400--or so--cfm fan going into the carbon filter and exhaust hot air from the top of the cabinet with another fan, or look into a carbon filter design that would utilize an inlet/outlet on each end so you can pull air through it------>to the vent in the wall. Either way, I just wouldn't feel safe running unfiltered air into that vent.
ProGroWannabe Reviewed by ProGroWannabe on . a light question :smokin: ok so i just want some feed back on these enviro lites. im thinkin of gettin 2 of the 200w as im really intregued by them after doin some readin. I know they're cfls and most will say stick with mh/hps but apparently they have a higher lumen/watt output than other lites and the light it gives off is 100% par which is grat for plants, right?? and as they are cool running they can be placed right on top of the plants so the lumens arent lost over distance. so guess im just lookin Rating: 5
