Almost all of the normal bulbs are on dimmers in my house and they rarely
blow. But then, I don't recall ever replacing the one in the walk-in-robe and
it gets switched on-off quite a few times every morning and night. I think it's
about 4-5 years old. I have found that Philips ones last a lot longer that the
cheap ones. Soemtimes the problem is that the lamps are manufactured
overseas and are rated at 230V. The real mains here is different from place
to place. In some states, they sell 260V globes to help reduce the problem.
