Should I Turn Off The Lights?

When should you turn the lights off?  Whenever you leave the room, of course!  Does that sounds like the correct answer in your home?  It definitely was in ours!  However, according to the U.S. Department of Energy, that is not always the case.  In fact, whether or not you turn off a light depends on the type of light.  Read on to figure out the correct plan of action for your lights.

Incandescent Lighting

These lights are the most inefficient and should therefore be turned off whenever possible.

Halogen Lights

Though these lights are more efficient than incandescent lights, they are still better off being turned off whenever they are not necessary.

CFL Lights

Whether or not to turn off these lights will depend on a variety of factors including the price of electricity and the time of day, but typically you can follow this rule of thumb from the Department of Energy:

“If you will be out of a room for 15 minutes or less, leave it on.
If you will be out of a room for more than 15 minutes, turn it off.”

The life of a CFL bulb is affected more by how often it is turned on and off rather than by how long it is on for.  Therefore, depending on the situation, it could definitely be beneficial to simply leave these lights on.

LED Lights

Turning a LED light on and off does not affect its lifespan, therefore there is no negative consequence of turning these lights off when you leave a room.
