^^^ is correct. With all the new lights, par is where it's at. Ceramic put's out more photons per watt than even the new black dog phytomax 2's.

Absolutely! I have an 8x8 flower room also. Added a second 1000w and things went nuts! In a good way! My low/high is consistantly in the 69°/77° range. Currently have only 4 plants and it's really crowded now. Had to move a Sour D and a Cookies Kush between the lights as they have tall kolas 5' high! Which actually works out good because they are both getting bombarded with light from both sides, and I was able to put a GG#4 and another Cookies Kush right under each thousand watter!
