I have the orbit system for my 46 bowfront that is 3 ft. (36") long, I am happy with the lights right now,but i know how much better my tank will do with metal halides. The problem is i really love my blue actinics on during the dawn/dusk effects and the colors really stand out. My question to anyone and everyone out there is, does anybody know the best reasonable price i could get on a system including halides with power compacts. I have been looking and the best prices i see range from $600-$1000. SO i know i want to do the right thinkg if im going to spend that much on it. any advise or suggestions about halides or lighting in general would be helpful too. My favorite look on a tank is the glimmer of halides with a the tint of blue/white, i hate when things look yellowish. And i love looking at my tank with my blue actinics power compacts on only too.
