More light; Less money? Sounds like a win-win. ENERGY STAR qualified residential LED lighting uses at least 75% less energy, lasts 25 times longer than incandescent lighting and provides optimal light color. LEDs are generally estimated to last at least 25,000 hours, and often up to 50,000 hours. Incandescent lights only last 1,200 hours, so you’d have to replace an incandescent light 42 times to get the light of a single, solid-state LED. CFLs (A compact fluorescent lamp [CFL], also known as a compact fluorescent light or energy saving light or less commonly as a compact fluorescent tube) by comparison, usually last 10,000 hours, so you’d only have to change them 5 times to match one LED light.
