I have tried a few of the LED's light bulbs from Fry's and Sams Club but they only sell 1.5 and 3 watt versions. The manufacturers state that these are 20 and 40 watt replacements but I have found them to be too dim for my needs.
I found a website
that sells 7 and 13 watt LED's and these perform MUCH better. I use them for 60 and 100 watt incandescent replacements in hallways and my home office. They also use a lower multiplier for calculating the replacement bulb wattage. For instance their 3 watt bulb is stated to replace a 20 watt incandescent (the Sams Club bulb said a 3 watt was a 40 watt replacement).
I think quality LED light bulbs are a great investment. The payback period is less than for solar panel installation and they are better for the environment than CFL's.
