LED stands for light-emitting diode. This technology is not new, but it is revolutionizing the way we live, work, and play. LEDs are special because they create light instantly while producing very little heat and consuming a fraction of the electricity of a standard light bulb.
LED bulbs are still more expensive than their incandescent equivalents but they are far cheaper to run. How much exactly are we talking about?
There’s considerable variation in the price and performance of all bulb types but the below figures are typical:
Although the LED bulb costs around eight times as much, it lasts 20–25 times longer and the lower running costs add up over time.
