PCs are nearly as effecient generally and probably more
efficient for an aquarium because of the light spread --
good parabolic or psuedo-parabolic reflectors make a lot of
difference.  The bulbs last a long time and decent ones
will have about 80% of their rated output even after a year
or two of use with negligible spectral shift.  You can get
them with a color temp high enough (10,000 K) them they
seem about as bluish white as good MHs.
