34g Solana - Solina disco ball with phoenix 150w MH. Ballast is Coralife or Coralvue electric. I bought the tank used, so the ballast may or may not be stock. It probably is, though.
14g Biocube - Stock PCs, 50/50 and actinic. Coralvue I think. I will be switching to an LED retro from Rapid soon.
6g Edge - 2x m16 LED bulbs w/o lenses. 2 blue and 1 white on each. I'll probably be adding more LEDs or doing a 6 LED retro just to get better coverage.
1'ish gal bowl - gu10 bulb with standard socket base, 2 blue one white with 60* lenses.
All work well, but I prefer MH. A 250w Radium bulb on an m80 ballast is my favorite set up, but it's too intense for my solana. LEDs are being used for heat reasons on the other tanks, but work well. I just prefer the look of MH.
