I have a fluorescent bulb in a torchiere in my office. Over time it
seems to get dimmer which I don't like. I feel like buying another one
but that seems like a huge waste of money. Do they normally dim over time?

You are quite correct, all fluorescent lamps are rated in "initial lumens"
as over time they diminish

Yes.
Talking to a supermarket manager on saturday, he commented that all bulbs in
the stores are replaced every two years and it made a big difference.

Greetings,
I know they get dimmer but what I don't know is if they become
significantly less efficient. Do they use less energy as they dim,
etc, etc? Does anyone else here know? I don't mind using more dim
florescent bulbs to extend bulb life so long as I am not paying extra
for the energy.
Thanks,
William

This is only logical thinking, not sure knowledge, but,
since a flourescent requires a certain voltage from its
xfmr to burst into light, I'd say all they've done is
lower the required current to stop them from glowing,
in order to allow dimming them. But I'm not sure of
that, so ...
I'm sure Google would turn up plenty of info,
including design infom
