This article makes a comparison: “A LED can last for up to 100,000 hours compared with the 1,000-hour lifetime of a typical lightbulb and the 10,000-hour lifetime of a typical fluorescent lightbulb.” This is misleading in comparing the maximum LED lifetime with typical bulb lifetimes. The typical lifetime of an LED depends on the application. LEDs for flashlights are often advertised at only 10,000 hours, yet there are long-life incandescent bulbs rated at 20,000 hours. Rating bulbs is complex.
