If you have a lamp that requires 75 Watt incandescent bulbs, you’d better stock up now, because production will cease next month. If you need 60 Watt bulbs, you’ve got another year to stock up. And 100 Watt incandescents have already been phased out last January. Why? Federal Regulations are calling for new, energy-efficient lighting including CFLs (compact flourescents) and LEDs (light-emitting diodes). These new types of bulbs are much more energy efficient than the old incandescents, which were first demonstrated by Thomas Edison on December 20, 1879.
