Time to replace my t5 bulbs and metal halides. My fixture is a outer orbit 2 x 250w mh and 4 54w t5's plus I have 2 extra t5's retrofitted. One on each side of fixture or one in front and one in back of tank. I currently have 2 10k xm mh's and 2 whites(I think midday sun 420nm) and 4 blue (I think pure actinic 03 460nm) I have already ordered the mh's. I went with 15k xm's this time. I like the more cool blue color. I'm going to order the t5's this week. I've always gone with geissman's but with all the chatter about the ATI bulbs, wondering if I should try them. What are everyone's thoughts?
