I'm running 12 sol strips and 2 red/blue strips in a 5' x 5'. The 12 Sol strips are under powered with all 12 running off 1 320 watt driver or a little over 26 watts per strip. 40 watts per strip is where I should be at in flower.
That said I'm extremely happy with my results. Sorry I can't offer any numbers, but I can compare with a 1000 watt MH I used in the same space.
