LED Bulbs

LED bulbs use 75% less energy than incandescent bulbs and last 25 times longer. A $2-5 LED bulb lasts 25,000 hours compared to 1,000 for incandescent. The Department of Energy estimates switching your entire home to LEDs saves $225 per year on electricity. By 2027, widespread LED adoption in the US could save the equivalent annual output of 44 large power plants. The light quality argument died years ago — modern LEDs offer warm tones indistinguishable from incandescent. This is the rare swap with literally zero downsides.
