Recommendation:

Replace all of your light bulbs with LEDs. They work better and last longer than either incandescent or CFL lighting.

All the Facts:

According the the EIA, lighting is responsible for 10% of home energy usage. In Osram Sylvania’s 2016 lighting survey, only 39% of respondents will replace their next light bulb with an LED. According the the US Department of Energy, LEDs use 20% of the energy that an incandescent would use, and last 25 times longer. Additionally, LEDs switch on instantly (unlike CFLs which require a warm up period to provide full lighting levels). With pricing on LEDs dropping like a rock, it’s become clear that CFLs were just a bridge technology. In fact, in 2016 GE announced that they will be discontinuing manufacturing of CFLs in favor of LEDs. What Sylvania’s survey did not cover was how many incandescents were still in use, but with 39% of the country not having purchased the most efficient type of light bulb (LEDs), the 10% of home electricity use dedicated to lighting could continue dropping for years. Attacking this part of your energy usage is not only easy, it pays for itself.

Note: The lamps used for the above comparison were: incandescent, CFL, LED

According to the Department of Energy’s Residential Lighting End-Use Consumption Study, U.S. households averaged 1.6 hours of use per lamp (lamp being the technical term for bulb), 47.7 watts per lamp, and 67.4 lamps per household. That means that the average household used 5.6 times more electricity on lighting than they would have if all lights were LEDs.
