What Are Incandescent Equivalents?
The incandescent equivalent is a way to compare and measure various light sources to conventional incandescent light bulbs. As displayed in the example below, find the incandescent equivalent of a compact fluorescent lamp (CFL) to a conventional incandescent light bulb by grouping together similar light output in lumens.
Incandescent Bulbs |
Compact Fluorescent Lamp (CFL) | Light Output in Lumens (lm) |
25W | 5-7W | 220 lm |
40W | 7-8W | 420 lm |
60W | 11-12W | 720 lm |
75W | 13-18W | 930 lm |
100W | 18-23W | 1300 lm |
