Pick the Right CFL Lightbulb Based on Watt Rating

By Jason Fitzpatrick on February 24th, 2012

After buying 75w and 100w bulbs all your life, it might be difficult to make the jump to low-watt CFL bulbs that top out at around 45w–use this handy chart to pick the right bulb.

Courtesy of EnergyStar.gov, the above chart helps you make the translation between the regular watt ratings your used to and the new ratings on CFL bulbs. If you need a 150w reading bulb, for example, what you really need is a bulb that puts out a nice healthy 2,600 lumens or so. To make sure you’re getting that kind of output, look for a CFL bulb in the 40-45w range and then, of course, double check the documentation on the box.
