Just a little over 3X3 i think, and for the 400w, i would love, and it's not the bulb i worry about it's the damn lamp that cost like 50X that ammount LoL

pluse i am trying to make a shoping list of what i need and how much it's gonna cost me, right now i only got 55$ but since X-mas is near that well change a little,(considering how poor i am, i am not sure how much)
