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.

Yes, a light meter (any vaguely modern photographic model anyway) is
perfectly capable of accurately reading normal and even very dim room
light. Some of them even come with conversion tables to give you
physics units instead of photographic units; but if you're just looking
to quantify the difference between two bulbs, even the photographic
units are fairly useful.

Thanks, David; much appreciated.
