It's relatively easy to choose light bulbs for the bedroom; for the most part preference is the main factor.
Bedroom lighting is fairly similar to home office lighting in that you don't need a terribly large amount of it. It's a good place in which to save energy by using low-wattage energy efficient light bulbs like compact fluorescents. Compact fluorescent light bulbs now even have dimmable varieties, so you're covered for all your needs.
As huge amounts of light are not needed, you can benefit from small fixtures and low-wattage light bulbs. If you've got a dimmer switch in the room, I'd go with dimmable compact fluorescent light bulbs. A 13 watt CFL running at half power (50%) would burn only 6 watts. If you want to closely match the color of the light from incandescent (with which you're probably most familiar) light bulbs, look for a color temperature of 2700K to 3000K. Dimming just seems to work better with lower color temperatures.
For a brighter, whiter experience use a color temperature around 4100K to 5000K. Light bulbs with those color temperatures give off a nice white light, much different from the yellow of incandescents. If you go even higher on the color temperature scale, you get into 6500K which is considered daylight color temperature. 6500K is another white light, but it has a tinge of blue.
LED light bulbs would also work very well in bedrooms. Two or three flood LED light bulbs would provide adequate illumination while consuming very little amounts of power. LEDs are also usually dimmable.
