I wonder about taking the ballast out of the fixture and remote mounting it somewhere? I'm thinking, although I have yet to try one on a tank, that the ballast is responsible for some of the heat you're seeing. I think I'm gonna go with one of the 27w quads on the 10 gal
and 2 15w actinics for starters. Also...maybe put a hole in the top of the fixture for heat to escape? Just some thoughts.
As far as the comparison to MH
goes... I have never used MH
lighting so there is probably no one on earth that knows less about it than I do. But, unless I'm mistaken, the lumen rating has something to do with how bright the light seems to the human eye? Don't believe it is really an accurate measure of intensity and also don't believe the current technology in fluorescent will ever compare to the intensity of MH
When I set up the 29, I'm thinking about doing a pendant with the 65w LOA bulb and a couple of PC
actinics. What do you think about that idea? The pendant, IMO
, would mitigate the heat issue since it will be several inches off the tank. Tank will house a dwarf lion and have LR
