Incandescent bulbs, as Edison designed them, are better than any other bulb, BTW. It took him 10,000 tries, and he finally got it right. If there were any need for improvement, don't you think he'd have kept experimenting?
Flourescent bulbs look too artificial, and the light they put out looks awful.
I, personally, only use NOS Edison made lightbulbs. Once you've read by the light of one of these babies, you'll never want another indoor light. And, I only use Gibson approved light sockets. The quality of the brand name on the socket lends itself to purer, thicker, brighter light that no one can come close to comparing to.
