When incandescents are outlawed, only outlaws will have incandescents.
How many people will actually switch to LED bulbs when the federal ban on incandescents takes effect next January? A Yahoo article on new 100-Watt LED bulbs shines some light on this controversial topic. New developments mean that brighter LED bulbs will likely go on sale next year, after a government ban takes effect. The new bulbs will also be expensive — about $50 each — so the development may not prevent consumers from hoarding traditional bulbs.
California has already banned stores from restocking 100-watt incandescent bulbs.
Besides being expensive, there are other drawbacks to LED bulbs. For example, many of them are not "dimmable". In my house dimmer switches are used in most rooms so that I can adjust the lighting to reflect my mood.
The notion of energy efficiency is a noble one, however, the feds may be flipping the switch too soon on this developing industry.
