The incandescent light bulb is not dead
More efficient incadescents are hitting the market as an alternative to more expensive compact fluorescents or LEDs
Despite misleading media reports, Jan. 1 did not mark a ban on the manufacture or import of 60-watt and 40-watt incandescent bulbs. Reports typically suggest that consumers get used to buying pricier, more efficient compact fluorescent or LED bulbs, or else stock up on incandescents while supplies last. Actually, there is no incandescent light bulb ban in the U.S. In fact, more efficient incandescents (such as a halogen 43-watt to replace the 60-watt) are now on the market.
