How long should light bulbs last?

How long does a bulb last? Well bulbboy has been
going strong (mostly) for nigh on:

Different bulb last different amounts of time.
An ordinary 60 watt incandescent bulb is supposed
to last about 1000 hours. Usually you will see a
"rated lifespan" on bulb packaging. In bulb testing this
number is the median at which 50 percent of the test
bulbs had popped, and 50 percent were still lit.

So what does this mean in every day terms?
It all comes down to a bit of luck really. If lady
luck is on your side you won't have to visit the
bulb shop too often.
Does any bulb ever reach its expected rated life.
Answers on a postcard please...

It is always a good idea to have a few bulbs spare in
the cupboard, because

In this world nothing is certain but death and taxes (and bulbs popping).

ps. see how many days old you are at
