Choose a CFL between 13 watts and 15 watts. It will light as brightly as a 60-watt incandescent light bulb.
Most manufacturers include “product equivalency” numbers on the package, so you might see a label that says “soft white 60” or “60-watt replacement.”
Here’s a guideline for CFLs that replace incandescent bulbs of other wattages:
Incandescent CFL
40-watt 7-9 watt
60 watt 13-15 watt
75 watt 18-20 watt
100 watt 23-25 watt
