Most of the time it is simple to switch to LED which use far less power and often can be switched to different color frequencies to get the type you prefer. Higher number Kelvin rating gets brighter (bluer?) light. I like 5500 K while my wife prefers 3200, so you have options for shopping but after that it is simply a matter of find the right base to match the fixture base.
I find the better LED options on E-bay.
