Yeah I also run 3 400W MH lights but that is on a 190g SPS tank Rusty. I looked for that thread on RC but couldn't find it again. This guy just ran about 8 T5's on I think a 100g tank and it was one of the nicest tanks I have ever seen. He was from Norway or Sweden I think. On a 20" tank you are probably going to get pretty good penetration with T5's

I don't, I like the look of VHO better and you seem to get better coralline growth with VHO. I don't know how they compare as far as par goes though but I am sure that one of the people that know a lot more about that than me will chime in.

HA I found that thread finally about the guys tank that is lit by only T5's and it is impressive. Further on in the thread he talks about his lighting quite a bit and how he is upgrading it. You may find it useful but it is truly an impressive tank.

power consumption would need to be considered too. 8 54w t5s would be about 4 amps, 2 250w MH are about 6amps. so lets say 10 hours a day for 30 days. 8 t5s would cost you about $15. MH would be about $21 (at 11cents per KWh)
considering t5s are about $25 each, that's $200 for 8 bulbs, in comparison, $200 will buy a very nice pair of MH lamps. so in the end, it'll cost about $60 a year more for MH. hmm...makes me want to reconsider t5s
