I looked into that. Your right I think I could do it. I never cared for the light being as big as the tank, like they are often with picos. First choice was a small neat clean light, Next best would be to have it all included in a small canopy, maybe 3" think. Most DIY drivers including the ones Rapid uses are all as long as my tank 7", So hard to see it all fitting. A full spectrum dimmable Par38 bulb would also work but by the time you get some kind of rig to hold it over the tank it also gets visually pretty big. The Par38 is my fallback plan though.
