Light output - 770 lumens. Energy used - 60 watts. Life - 2000 hours. 120 Volts. To save energy costs find the bulbs with the light output you need, then choose the one with the lowest watts. Lasts 2x longer than ordinary soft white. (Almost the same light output and lasts twice as long as a 60W, 850 lumen, 1000 hr. bulb.) Proudly made in St. Mary's Pennsylvania.
