Using LEDs as a replacement for incandescent and fluorescent bulbs in portable and mobile devices such as flashlights and vehicle lights, as well as stationary lighting in the home and office. LED bulbs draw considerably less power and are up to 90% more efficient than incandescent and halogen bulbs. In addition, although claims are made for some bulbs lasting 30 years, one can expect approximately 10 years for an LED bulb under normal usage. See LED.
