Whether the ballast is external or internal doesn't matter. It still has a ballast and is still going to create the same amount of heat and use the same amount of electricity. And you want to make sure it's a digital ballast that is capable of running both Metal Halide and High Pressure Sodium. Metal Halide is strictly for vegging, for flowering you switch the bulb for High Pressure Sodium.

If you have a 4x4 tent, go for 600.

Are we talking feet or meters or what? 1.2 feet isn't enough for anything.
