Might help to change to fixtures with a reflector, so the light goes where you want it.
They have 42W CFL's that claim to be a 150W equivalent - but if you don't think a 27 = 100, then you might think the 42 = 100.
Not with the current crop - they had some CFL's that claimed to be dimmable, but with the unfortunate side effect of catching on fire. Not an admirable trait for home electronics...
If you really want to dim your fluorescents you can go with old-tech F34T8 or F40T12 strip fixtures and commercially available dimming ballasts. But you need a special dimmer and a second hot lead from the dimmer to the fixture for the control voltage. And you have to burn in new lamps for 100 hours at full brightness before dimming them.
