How long do CFLs last?
The life of a CFL will vary greatly depending on the quality and price of the product. As a guide, a household globe is expected to run for approximately 1000 hours each year. Therefore low cost 4000 hour CFLs will last up to four years, mid priced products ranging from 6000 to 8000 hour lamps will last roughly six to eight years, and the best quality CFLs will last between 10000 and 15000 hours or ten to 15 years. The approximate years are obviously dependant on the frequency of use. Beacon Lighting always suggests buying a recognised brand to ensure your light globe lasts the stated hours.
