fluros degrade in performance all the time

sometimes when putting new badly stored fluros in you can see the gas
revolve around the cylinder when the light is first turned on .

However, seeing there are so many photographers in here, you should know
best.

I was wondering how sensitive a light meter is and if it would work
inside.
I just replaced a flouro light bulb (lasted 2.5 years and saved me over
$80!) and noticed that the new bulb is now somewhat brighter despite being
identical in make and consumption and I'm curious if the bulbs lose
efficiency over time and by how much.
