If you're wanting old school, you might be better off with a 4 bulb T5 setup.

The only thing I would add is do not buy old used mag ballast. They break down and in time become only 70% efficient. The electronic ballast are sometimes 99% efficient. If you have an old mag ballast that gets supper hot , that is wasted energy plus in most cases will only run probe type lamps. Radium and Phoenix run on Pulse start ballast either M80 / M138 or higher or electronic. M57 - M59 will not. My best looking coral where under MH. Today I only run LED, but I care more about fish so I just have frogspawn and softies
I would second this with it only being a 20 gallon tank. Or, move up to something 75 gallons or largerWith the 30" long by only 12" wide, that's tough without lots of light spill.

I have a 2 bulb T5 fixture sitting in the garage. . . could always get that back up and running. . . but I have already been there done that. Want MH. . . don't need. . . but wantI would second this with it only being a 20 gallon tank. Or, move up to something 75 gallons or larger
All my original Coral Vue ballast when it was owned by David where 90% efficient. Post #35 according the label is 96%. I still remember switching from heavy tar ballast with T12 lamps to the new electronic ballast with T8 with the weight and heat/energy savings.Where have you seen electronic 120V halide ballasts at 99 or even 90% efficient? I think someone is confusing power factor with power conversion (efficiency). Very different things.
