my 400 watt hps puts out like 55,000 lumens. it cost me 194 best buy i ever made. i also use 2 100 watt hps lamps for side lighting. i have 6 more 1 ft 1 tube t8 floros but i dont think it will even matter, there can be too much light right? is 55,000 plus whatever the 100 s put off plenty for a 3 by 3 by 5 space?
