Welcome to the forum!
CF bulbs and fixtures are going to be a wave for sure. Advances in ballast designs, and obtaining a 'low' start temp. will be sure to have a lot more choices available.
Fixture cost is less than MH, light is 'white', with instant (almost) illumination, and no 're-strike' time.
There are also quite a few "high-bay" type fixtures available; great for warehouse lighting, and energy mgt can be connected to them, allowing partial, full, or on/off via an occupancy sensor.
Keep saving energy!
