ENERGY STAR LEDs are your best bet. Look for the ENERGY STAR® label, awarded to select LED products that meet strict efficiency, quality, and lifetime criteria. While LEDs are already beginning to surpass the quality and efficiency of existing lighting technologies, testing by the U.S. Environmental Protection Agency has shown wide variability in performance of LED products. Only well-designed products used in the proper applications will provide the energy savings, lighting quality, and long-life benefits of LEDs.
CFLs have come a long way. Compact fluorescent lighting has not always been the best solution for many homeowners, despite the potential for high energy savings. Many early buyers were dissatisfied with things like flickering, humming, and the harsh quality of light.
CFL technology has come a long way. The CFLs you find on the shelf today:
- provide high-quality light in a range of colors that rival the array of incandescent options;
- no longer flicker or hum;
- come in an assortment of shapes to suit nearly every lighting need. There are even covered versions for those who prefer the traditional look of incandescent bulbs;
- and last as long as 10 years.
