After 20,000 hours of operation,the full lot of 200 sample lamps are all still operating.Moreover,the DOE said that average lumen maintenance remains above 100%of their initial output.The tests are being conducted in an environment where the ambient temperature is maintained at 45°C.

Based on typical household lamp use that averages three hours per day,the DOE says that the 20,000 hours is equivalent to 18 years of residential usage.Such a lifetime makes the lamp price more palatable with Home Depot currently selling the product for$30.
