Because they are claiming to be as bright as a 75W incandescent lamp. 
If you look at the lamp lumen ratings, you will generally see that they
are lying, and the lamp is really a little brighter than a 60W light
bulb.  Or maybe they are as bright as a long-life 130V 75W lamp when
operated at 120V.  

Compare the lumen ratings of the 20W twisty lamp to a 20W fluorescent
and a 75W flourescent (that would generally be a 8 foot linear lamp) and
you will see what I'm talking about.
