LEDs have changed and gotten much better. We replaced all our major-use 18W incandescents with 4W LEDs and now have more light rather than less.
Main thing is to get yellow light LEDS, not white ones which are very hard on the eyes. We use a white waterproof one outside and wouldn't mind it in the bathroom but everywhere else we use yellow light LEDs.
They cost $25 apiece but you only need one in dual fixtures and they last much longer than incandescents, not to mention they run cooler so you don't have to keep replacing light covers. I got mine in Quartzsite, AZ at the annual swap meet. Many RV stores now carry them.
