T5's are just a different size of tube. a VHO is a T12 so it is 1.5" diameter.. a T10 is 1.25" and a T8 is 1" so a T5 is 5/8" diameter. and PC is a T4 base. what they have found is that if you pump the same power into a smaller diameter tube you get a more intense light.
so basicly both a T5 and a T12 are normal floressent tubes, a VHO T12 is designed to handle more power than a standard T12. and the same holds true for T5's.. there are HO (high output) and NO (normal output)
