I have old heat lamps connected to fans in my bathrooms. I absolutely will not ever need a heat lamp in the bathrooms so just been leaving the door open while showering. Is it possible to replace them with just regular lamps?
I don’t have windows in the bathrooms, so the fans are important. They are not separate switches so both come on at the same time. Thanks for your help! Please be nice I googled and I’m not getting anywhere.
