So, I have recently started building my 90g back up, it is light with a pair of ocean revive LEDs, which I had success with. Now I would like to supplement my lights with more violet spectrum (400-450nm). As well as place some lunar lights in the hood for some night viewing. My question is what do y'all use or what would you like to use? I am pretty handy but it appears that "build my LED" no longer exist, so I am looking for ideas. Jim
