What is the average life span of a CFL bulb?

The average life span of a CFL (Compact Fluorescent Lamp) bulb typically falls within the range of 7,000 to 15,000 hours, with many manufacturers advertising a life span around 10,000 hours. Therefore, the most representative option here is 15,000 hours, as it better captures the higher end of the typical range.

CFL bulbs are designed to be more energy-efficient than traditional incandescent bulbs and, consequently, last longer, but they do have a finite lifespan which is ultimately affected by factors such as usage patterns and operating conditions. While some lower-quality CFLs might last closer to 8,000 hours, claiming an average life span of only 8,000 hours is somewhat misleading when considering the majority produced today, which generally last longer. Therefore, the best average estimation for a typical CFL bulb, based on common usage and manufacturer specifications, would indeed be 15,000 hours.
