So, now I am up to thinking about lighting for my new 50 gal. After looking at some of the DIY projects and thinking about the bulb costs involved with my coralife currently over my 55 long, I have been thinking about making my own lighting. My question is, why have I not seen any of these lighting suggestions that use some of the flourescent lights that fit in a standard socket. I was looking in my local Lowes and found 23w bulbs @$6.79 each. Built in ballast. These were 6700k bulbs btw not your standard soft white. Is there something that I am missing that would make these not feasible?
