It is time, as a matter of pride, as well as a matter of national security, for the United States of America to lead the world in the energy revolution, and not lag behind Japan or Germany.

LED Lighting

LEDs or Light Emitting Diodes as a light source offer benefits in terms of maintenance and safety. The typical working lifetime of a device, including the bulb, is ten years, which is much longer than the lifetimes of most other light sources. Further, LEDs fail by dimming over time, rather than the abrupt burn-out of incandescent bulbs. LEDs give off less heat than incandescent light bulbs and are less fragile than fluorescent lamps. LEDs are built inside solid cases that protect them, making them hard to break and extremely durable. Since an individual device is smaller than a centimetre in length, LED-based light sources used for illumination and outdoor signals are built using clusters of tens of devices.
