Code requires a lamp fixture specifically designed for showers or wet (not merely "damp") locations. As far as I'm aware, one designed for a 60w max incandescent bulb can be fitted with a 23w Sylvania micro-mini bulb (as bright as a 100w incandescent, and the smallest 23w CFL i've seen) which may be brighter than fixtures that use two-pin or four-pin fluorescent bulbs. A drop lens or convex lens will light the walls better than a flat lens

not sure what you mean by not wanting "dull". i went with two halo 4" can lights with the wet area trim that seals it up. not a chandelier, but great light & they are unobtrusive.
