What are the differences between LED, CFL, and incandescent light bulbs in terms of energy efficiency and lifespan?

LED light bulbs are the most energy-efficient and longest-lasting among the three types. They use less energy and can last up to 25,000 hours. CFL bulbs are more energy-efficient than incandescent bulbs but less so than LEDs, with a lifespan of around 10,000 hours. Incandescent bulbs are the least energy-efficient and have the shortest lifespan, typically lasting around 1,000 hours.
