Another off-topic question
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. -- Alan Erskine

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 . "Alan Erskine" wrote in message ...

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.
