If you folks have 48" tanks, rather than trying to squeeze in AHS compact fluorescents, why don't you just use 48" (46.5") 54 watt T5 HO lights. They will fit over your tank perfectly. The use the same technology as the CF bulbs but are more efficient because they are linear instead of bent tubes and have fewer restrike issues, and the bulbs are cheaper. With a good reflector, you can fit two 54 watt T5HO lights in each 3 inches of width over the tank.
The only disadvantage is that there are not retro-fit kits as commonly available for them. But there are places which sell miro-4 polished reflectors for them, and ballasts and sockets are easy to get (ballastwise.com for ballasts, 1000bulbs.com for mini bi-pin sockets).
