How Long Do Incandescent Light Bulbs Last?: 1 Minute to Understand Bulb Lifespan

When it comes to lighting solutions, one common query is about the longevity of incandescent light bulbs. How long do incandescent light bulbs actually last?

Typically, incandescent light bulbs have a lifespan of about 1,000 hours. This means if you use your bulbs for three hours a day, you can expect them to last around a year. However, their lifespan can be influenced by various factors, including the wattage of the bulb, how often it is turned on and off, and the quality of the bulb itself.

Although they are widely used, incandescent bulbs are not the most energy-efficient option available. They convert a significant amount of electricity into heat rather than light, which can lead to higher energy bills over time. Therefore, while the initial cost of incandescent bulbs is lower, their shorter lifespan and inefficiency make them less favorable compared to modern alternatives like LED and CFL bulbs.

Comparing Lifespans:

To put things into perspective, here’s a quick comparison of lifespans:

As you can see, both CFLs and LEDs offer significantly longer lifespans, providing a better return on investment despite the slightly higher upfront costs.
