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:
