What are the Low Energy lamp equivalent wattages?
There are slight variations with these Compact Flourescent Lamps (CFL for short), because of differences in folded-tube design, efficiency, and in starting (ballast) types. The electronic ballast types (versus magnetic) are usually slightly more efficient. However, here is a basic list: Tungsten Lamp Energy saving CFL Light Output(Lumens) 25W 5-6W 220 – 300 40W 8-11W 400 – 550 60W 13-18W 850 – 1160* 100W 20-25W 1200- 1750* * The 1160 (18W) figure is roughly equivalent to a 75W tungsten lamp, and a 1750 (25W) CFL is roughly equivalent to a 120W Tungsten lamp.
