which fixture should i get?

i have a 55 gallon soon to be reef aquarium, im looking at either:
Current Nova Extreme Pro Saltwater T-5-
3-54 watt 10,000°K
3-54 watt 460 nm actinic
total of 324 watts which is around 5.8 watts per gallon

AquaticLife Compact Fluorescent Lunar Light-
2 65W Actinic
2 65W 10,000°K
total of 260 watts which is around 4.6 watts per gallon

down the line im looking to keep SPS,LPS, softies and a tridacna clam, so is there a real different between the two? such as:
one is t5 while the other is compact flourescent
or
that one has 5.8 watts per gallon and the other is 4.6 watts per gallon?
so i would really like your personal opinion on what would be best for SPS, LPS, softies and tridacna clam. the only different i see is that one is 40 dollars more then the other.

 

I would buy the Nova and change the stock bulbs within 6 months. PC are good but T5HO are better when used with individual or molded reflectors. Watts per gallon are a measure for T5NO, T8 and T12 bulbs.

 

Go with the Nova. You can keep a wide range of corals, depending on placement and Nova's are great fixtures.
