- To earn the ENERGY STAR® label, lighting products are independently tested against strict efficiency and quality criteria set by the Environmental Protection Agency.
- The ENERGY STAR label guarantees quality, performance, and efficiency. Bulbs that are not ENERGY STAR certified do not meet the high standards for energy use, and some will continue to use power even when turned off.
- ENERGY STAR LEDs can have a useful life of at least 35,000 hours or 12 years based on use of 8 hours per day. The lifetime of a non-certified LED is not tested or guaranteed.
- While ENERGY STAR LEDs are tested for light quality and consistency, many non-certified LEDs will flicker, shift in color, look dim, or offer uneven light over time. The ENERGY STAR label also certifies that the LED illuminates instantly when switched on.
