I'm going to *guess* that you will probably see about the same to maybe a
bit more light in the tank, but that that light may be a bit more focused
and not spread over the tank as evenly. My expierience with the AH supply
reflectors is that they are quite good, and the compact flourscents are
pretty bright even before you add the reflectors. I mention the "focusing"
of the light since typical shoplights aren't all that directional since the
"reflectors" aren't usually all that great, but the AH supply reflectors are
good enough to produce a significantly higher amount of light going straight
down from the reflector than coming off the sides. Probably no big deal but
I thought I'd mention it. You'll want to play with the positions of the new
lights until you have them lighting the tank the way you want, then mount
them in those locations inside your new hood.
To say much more you'd need to go into detail about the type of bulbs you're
currently using and maybe the kind of shop light (some are better than
others). I'd try two 55 watters first since you can always add another pair
if you want more light.
