They're actually almost brand new. And I doubt all eight of them were
broken from the factory. Oddly, the ones they installed elsewhere in
the house worked better, but they were the twisty kind. The bathroom
ones are exposed so they're the kind where the twisty tube is encased in
a plastic sphere, to look like decorative incandescents.
They do produce *some* light right away, but it's less than half their
eventual brightness. The installer assured me that would change after
they broke in, but that hasn't been the case.
My opinion is that CFLs only make sense for lights that are turned on
and left on for long periods. In a bathroom, the constant on/off cycling
will kill them too fast for them to pay off.
The same is true for LED bulbs, really. While power-cycling won't kill
them, a bathroom light is probably on for less than an hour a day. The
payoff just isn't there for replacing them with something more
efficient, especially since for half the year we're also switching on a
heat lamp when we're in there to warm up the room.
