Energy efficiency ranking organization Topten has placed products by Satco/Nuvo, Ecosmart and Lightkiwi among the best LED bulbs available.
The organization has categorizes the LEDs into two diameters of parabolic aluminized reflector: PAR30, which fit in a housing that is 3.75 inches in diameter, and PAR38, which fit in a housing that is 4.75 inches in diameter. Lights are given a total score out of 100 based on energy efficiency, price and performance.
Satco/Nuvo’s S8971, the top light in the PAR30 category, is a 14W PAR LED reflector lamp. Its rated output is 860 lumens, and it replaces a 75W halogen. It offers a lifetime energy savings of 1,525 kWh, a lifetime cost savings vs halogen of $186 and a payback period with typical use of 5.4 years, according to Topten.
Lightkiwi’s LK-PAR30-10BV40, the top light in the PAR38 category, is a 15W PAR LED reflector lamp. Its rated output is 1100 lumens, and it replaces a 85W halogen. The bulb (pictured) offers a lifetime energy savings of 1,750 kWh, a lifetime cost savings vs halogen of $214 and a payback period with typical use of 4.3 years, according to Topten.
