I just picked a couple of these up. I am slapping one each in two dr150 II secret jardins (5' x 5' x 80"H) with 1000 watter on a flip/flop. It sucks how much space it takes up in the 80" tent but I only plan on a 4 week or so veg. I am pretty excited to be running some of these, if all goes well I will install 10 of them in my main flower. I have been pretty stubborn and cheap on hoods, it is weird because it isn't like me to cheap out on anything but I always used inexpensive hoods. After seeing the ill effects of an improper footprint first hand I am changing things up. I will get some pics of the setup when it is done sometime this week.
