I’m aware that the electrical power requirements are considerable for freezers and refrigerators.  
My question concerns people who turn the lights off and on in their homes even for 1/2 hr. or so. Many spouses of people that I know are upset because their spouse leave the lights “burning” when not in use.

Is their a considerable cost saving by turning the lights on and off when a pt enters or leaves a room? Yrs ago I remember that the more a light bulb is turned on and off the sooner the filament inside the bulb fails.

With the above question in mind, how does fluorescent lighting differ from incandescent lighting?
