Lighting needs are figured by lumens per sq ft. For vegging you want a minimum of about 3000 lumens per sq ft. For a 12 sq ft space, that is 36,000 lumens. So a 4' 8 tube fixture (54W tubes, 5000 lumens each) that puts out 40,000 lumens would be great.
Truly, I have found the expensive bulbs to be about the same as cheap bulbs. I have had a 1000W HPS since 1998 and so have tried a myriad of bulbs. I personally have found that buying inexpensive bulbs and swapping them out frequently does great.
