I use a home depot light, macro growing like crazy. Lesson's learned though... design your fuge, if you're running one for macro, so that the water coming in will wash through the macro. My first set up allowed water to pass over and around the macro, and when the fuge filled up not all of the plant got water flow.

Now I have my water coming in on the bottom section of my macro section, and the water must travel through the macro to get to the top where the water spills over into the quasi-crypt section of the fuge.

Another lesson learned, measure twice or even thrice... cut once
