Hi, I was just given a free 264 watt compact fluorescent fixture, and I figure its a good idea to change the bulbs. Ive never used any thing but T5's and MH, so Im wondering if its better to get these dual output bulbs, that are 10000ºK/Actinic 460nm, or if i should just get two daylight bulbs, and two actinic. what do you guys think?
