We've got those big-bulb vanity lights in all of our bathrooms (including 10 in our master bath). They are so bright that I have unscrewed every other one of them just enough so they don't come on when the light is turned on. It's still plenty bright in the bathrooms. When the current bulbs go out (haven't had to replace yet after 3 1/2 years!) I figure I'll just screw the others back in, thus essentially doubling the life of my bathroom lights and halving the cost.
