I feel that the quoted lumens of the CFL's is for a 'young' bulb and

hallway light, I would say that at 2000 hours the lamp was down to 40%
of its original output.

You might think that, but in many cases you would be wrong. When I recently
replaced a year old Osram brand CFL with another of the same wattage, I
noticed immediately it was much brighter.

Then I looked at the old lamp and the box for the new one. The old one was
rated 2/3s of the lumens of the new one.

So in this case, and will all of the osram lamps we bought that day (we bought
several in different sizes and wattages) they were much brighter by design than
the ones just a year old.

What I want to see is a long necked refrigerator bulb. :-)
