Agreed...these are the best bulbs for the price. Once tested them and Geismann midday bulbs and growth was on par, but they are more then half the price. I think I paid $13 for them at Albrite. Best combination I found was a mix of 1:1 ratio of a daylight bulb like the GE's and a pinkish bulb like the Geismann Aquaflora or Aquamedic Planta. I am currently running the 2 GE's and 2 Aquamedic Planta bulbs. Best of both worlds. Growth and color. Using all daylight bulbs is great, but I can't stand the color look. Some use daylight bulbs with 10000k as well. Seems to work well too.GE 6700Ks are the ultimate FW planted bulbs. Relative cheap and monstrous PAR.
