Ahh right on, I'm just using the nanolux bulbs atm but will be switching to the Phillips when I need to change the bulbs. They say the bulbs last a year but I don't buy that, I'm going to replace them in 8 months to be safe. Also, I have no idea how bright the bulbs should be, they are bright, but I have nothing to compare them too so I hope they are OK haha. I'm being a little outrageous, my foot prints are 5x6, 5x5 and 5x4.5, from left to right. The 5x4.5 is because my res is over there and if my room was a bit bigger, I might had run 5x6 all the way around except for the ends without cross lighting.. The cross lighting is supposed to be where it's at! If I don't get 2 lb a light I'll publicly shoot my left nut off. Then again, I might lose a nut because this is my first real run with the lights and I don't even know how good they are yet haha
