Sorry, I should have been more clear. What I meant was that people with LONGER tanks (which tend to be DEEPER) are more likely to use 250W MH because of the greater penetrating power over 150W. These same people would also be looking at the LONGER lengths of T5s (e.g. 54W 4-footers) if they were comparison shopping simply because of their LONGER tanks.

Anyway, here's Grim Reefer's thread on 54W t5 PAR vs. 250W DE MH:

wow thanks for the input guys. the one reason i was questioning going to T5's is because i have bought a profilux controller, the second one in north america and it has the capabilities of dimming t5's to give more realistic sunset, sunrise and a ton of other options with the lighting. marc (Fudge) has been running a post on the performance of the controller for further info. but from what i have found i'm sticking with the 3 250w setup for now.

When it comes to pushing the envelope technology-wise for reefkeeping, the Europeans have one up on North America.

Sfiligoi has a similar T5/MH dimmer with the ACLS. Too bad I'd have to sell one of my kids to be able to afford such a setup =P
