Do people still use incandescent bulbs in America?
They last a long time, though, and I imagine a lot of people are still using their existing bulbs. I can't imagine doing that in CA, where our electricity is expensive, but if you're paying 6c/kWh, I suppose, may as well?
If there was a true environmental motivation for reducing our electricity usage, our bills wouldn't be 60% network charges, they would be 100% usage based charges.
Some lampshades call for a point source which LEDs struggle to replicate.
