Hi dedereweko ! I actually prefer all those lights because it allows me to give my plant light in all places rather than just up above. Especially in flowering because then I like to move the lights in real close so they are more efficient. Also because CFL is not high intensity lighting like metal halide or Hps it does not penetrate as well so its good to have side lighting. oh and im pretty sure that the 26 w cfl and 45 w cfl have a better lumen ratio as opposed to the bigger wattage ones hence making them more efficient . thanks for your suggestions though I appreciate it !
