Saving on Electricity: Leave the Light on
Many people use compact flourescent lamps (CFLs) as a way to save on electricity. Did you know if you use a CFL in a light fixture that gets turned on and off for short periods of time, you will spend significantly more money? Turning a CFL on and off for periods of less than 15 minutes can shorten its lifespan to that of an incandescent bulb.
If you are leaving a room that uses CFL lighting and plan to return within 15 minutes, the Energy Star program actually recommends you leave the light on instead of using the energy it takes to turn the bulb off and back on again in a timespan of less than 15 minutes.
What about the bathroom? Someone is always in there. Should I leave the light on or off?
If you have enough natural lighting to leave the light off during the day, that would be the best option. If you have to turn the light on and the bathroom is not clear for more than 15 minutes at a time, you might consider leaving the light on until everyone is done for the night.
