I don't run statistics, but I appreciate what you wrote because my
fluorescent lamps don't last more than a year or two, it seems.

I used to mark the bulbs with a Sharpie, but I stopped doing that long ago.
I don't think I *ever* got anywhere near the claimed life.

But we turn them on and off a few times each day.
