LEDs are everywhere. They’ve been a popular alternative to traditional Christmas lights for a few years, but they’re also used for everything from street lights to digital clocks, table lamps and TVs. What is it about LEDs that makes them so useful?
Unlike incandescent bulbs, LEDs don’t have a central filament. Electrons moving along a semiconductor produce light more efficiently in LEDs so they use less energy and are cooler to the touch. Because they use less energy they’re also often paired with solar panels.
LEDs have seen a drop in price over the last few years as well, and since they last longer they cost far less over time. It’s likely LEDs will continue to replace older lights in the future as part of the green energy revolution.
