u needa make a grow box and put those suckers real close to the plant, but hey man u can buy lights at home depot for like 15 bucks... instead of 200
use T5's myself (not that perticular fixture ) with added cfl lites ... works well in my little cab ... bulbs can be bought in 2700k 4500k and 6500k ... i like em and they are cheap to run for the amout of lumens ... imo
