Benefits of LED light bulbs
Ready to leave incandescent lighting in the dark? ENERGY STAR® LEDs are the most efficient lighting technology – at least 75% more energy efficient than incandescent bulbs.
By replacing an incandescent with a LED, you could save $75 in electricity over the lifetime of the LED bulb. And because LEDs can last up to 10-15 years, you won't have to replace bulbs nearly as often.
How to get the most out of your LED light bulbs
Change a lot of bulbs at once
Slowly replacing incandescent bulbs with LEDs as the incandescents burn out will feel less wasteful, but you won't see a noticeable difference in your electricity consumption graphs, or your electric bill, for a while.
If you change most or all of your incandescent bulbs to LEDs within one billing period, you'll see the difference right away.
Understand the lifespan of LED bulbs
While LED bulbs typically last about 10 times longer than incandescents, some people find that they don't live up to manufacturer claims of up to 10 years or 25,000 hours, for example. It's important to keep in mind that claims about the lifespan of an LED bulb's lifespan assumes a modest amount of usage, typically 3 hours per day, and ideal conditions.
Some factors that can impact the lifespan of LEDs:
Faulty wiring or bulb circuitry.
Exposure to hot or humid conditions.
Enclosed fixtures that aren't meant for LED bulbs.
Incompatible dimmer switches.
Those factors can also impact the performance of LEDs, sometimes causing flickering or an audible hum when the light is turned on.
