ATI sunpower.......great color and save money on electric bill. Strong par and a proven method to grow corals.

What are you planning to keep in your new 120g system? Lots of options really depends on what coral you intend to have and what "technology" you want to embrace. I say go LED :)

Consider LED if you DIY, a while longer for a commerical fixture as they are just now starting to use a greater number of spectrums.

Halides work well for all sorts of coral, and a good setup can be found used for cheap, though you need to be here 3 months to see the used selling forum. Heat can be a problem with halides as they impart more to the water through radiation. The extra electric usage by halides is minimal for me, about 10 bucks a month, but places with stupid rates like California would be 3 times that.
