Deciding to switch from incandescent light bulbs to energy-saving CFLs or LEDs is easy. Figuring out how many lumens your new bulbs should be is not. Luckily, we've got a handy cheat sheet for you that shows the right conversions for switching your home lighting needs from watts to lumens.
While some CFL, LED and halogen light manufacturers have made light bulb shopping easy for consumers by printing their bulbs' equivalent wattage right on the packagaing, others still seem to leave you in the dark about which bulb is right for your lighting.
The next time you're out shopping, take this cheat sheet with you and make sure you come homw with the right bulb:

One of the things I like about using the CFL's is that you can use a higher equivalent wattage without worrying about melting things. In our kitchen, the bulbs weren't bright enough AND, I was so tall that I felt the heart from them. So, we replaces the 80-watt max with 150 or so equivalent CFL. Now it is bright and cool. So far no issues.
I think a 3rd column would be helpful. CFL wattage, since that's what they list on the packaging (at least on the front). They may have the lummens on the back, but wattage is up front and prominently displayed...
This is a very helpful chart, as I struggled somewhat with determining the wattage/lumens and associated brightness when I moved from incandescent to CFL's. I have now moved to LED's (it's worth the initial cost/investment). Newer LED's are available that have a glow that is yellow like an incandescent that we are all used to and are nice. I am also finding some LED's that can be dimmed and slowly seeing a greater range of smaller fittings. Some older fan kits have trouble with the very small LED bulbs. Still LED's are so much nicer than CFL's, safer, cool bulbs, lower power usage and actually do last longer than CFL's and incandescent bulbs.
