What is the rated lifespan for most incandescent light bulbs?

The rated lifespan for most incandescent light bulbs is generally around 1,000 hours. This figure can vary slightly depending on the specific bulb and its intended use, but 1,000 hours is a common standard cited by manufacturers.

Incandescent bulbs, which operate by heating a filament until it glows, tend to have a shorter lifespan compared to other lighting technologies, like compact fluorescents or LEDs. The filament is susceptible to wear and degradation over time, which contributes to the overall lifespan of the bulb.

When considering the rated lifespan, it's important to recognize that factors such as voltage fluctuations and usage patterns can influence the actual duration that a bulb will last in a home or business setting. This understanding helps consumers make informed decisions when selecting lighting options for various applications.
