The Department of Energy is offering a prize of as much as $10 million to create the first solid-state replacement for the 60W incandescent light bulb, so you know it's a problem. Here are some suggestions for how to address high-efficiency, power-factor, and phase dimming compat-ibility requirements.rnThe lighting industry is exploring ways to replace the standard 60W light bulb with a more energy-efficient, HB-LED (high-brightness-light-emitting-diode)-based design. LED lighting offers the prospect of a 10-fold efficiency improvement over incandescent lamps. With a potential lifetime ofrn100,000 hours, this improvement would virtually eliminate maintenance and replacement costs.
