Have you been told you should keep the lights on when leaving the room for a short period of time, rather than turning them off and then back on? Do you believe that switching lights on and off too much can reduce the lifespan of the bulb? Both are misconceptions that stem from the belief that it takes more start-up energy to repeatedly switch lights on and off.
What many consumers may not realize, is that energy-efficient light-emitting diode (LED) bulbs are unaffected by being turned on and off. Even though there’s a spike when you flip the switch, it’s not significant enough to save you energy, or money.
One of the fastest and easiest ways to cut your energy bills — and save money over the lifespan of your light bulbs — is to change compact fluorescent lights (CFLs) to LEDs. ENERGY STAR®-rated LEDs last a minimum of 15 years.
The bottom line: Whenever you turn something on — whether it’s a light, a car engine or a computer — it’s consuming power. If you want to reduce your energy use, turn the power off, even if it’s just for a minute.
