LEDS are getting cheaper and brighter, there are other options like halogen as well. CFLs are just a really terrible idea overall. HAZMAT issues, plus the environmental costs of shipping them all from China in giant ships, coupled with the fact that the ACTUAL life span is nowhere near the advertised spans, and the fact that you need special ballasts to use them with special switches like dimmers and the like. And trust me, incandescents will still be around, they'll just get relabeled as "heat" lamps, and the price will probably go up to reflect the decreased production. Hell, places up north might actually benefit from the excess heat created by incandescents, at least in the winter. Once LEDs get ramped up and economically viable, they'll be all over the place, and that's probably the best case scenario, as far as longevity, heat, and environmental concerns. Not to mention the increased durability, and completely solid-state operation. Just have to convince the first and second adopters to justify the near $30 per bulb price to get the ball rolling.
