Light Levels and Lumens - is this info correct?

Lumens represents the amount of light emitted by a light source, such as a light bulb. Following are typical lumens levels for various light (CFL) bulbs.
Realize that recommended light levels will vary based on the person and the task.
When purchasing light bulbs, however, don't assume that more watts means more light, more lumens means more light.
So, watts really don't tell the story, but alot of the LED's are being compared to the the wattage of the incandescent.


That's the way that they run their ADs

Whats up with that?

Is this a big sham?

Looks about right to me; there'll be subtle differences in output depending on the manufacturer, but if you know the lumens and the watts, you can find the efficiency..
