PC's are T5's, just bent in half.  T5's might be more efficient than PC's 
for long tanks because they can fit over the entire tank.  For instance, a 
54w T5 is four feet long, just like a 32w T8.  That could give me very 
good coverage on my 75-gallon tank, while a 55w PC has some gaps when I 
put two of them side by side, needs a full set of wires on either side or 
down the middle of the hood.

I think also that with only half the exposed area, the lights will be 
slightly more efficient with the reflectors.

AH Supply doesn't make a 4' long fixture to reflect a T5 bulb.  I e-mailed 
Kim about this a couple weeks ago, and he wrote back that 4' long items 
are much more expensive to ship, break easier, etc.  I am considering 
buying two of his smaller reflectors and then using them end-to-end as a 
T5 reflector.  Or I may buy a T5 reflector elsewhere.  I hate to do that, 
because I really like AH Supply's stuff.
