Induction Lighting from EEI

The Edison Electric Institute writes about Energy Efficient Tips for Street and Area Lighting. The original post can be found here:
Induction (Electrodeless) lighting

With induction lighting, there are no filaments or electrodes. These systems consist of high frequency ballast/generator, a lamp (or discharge vessel), and a power coupler. The systems range in wattage from 23 Watts to 165 Watts, with efficacies of 48 to 73 lumens per Watt.
Along with their high lighting efficacies, they have high power factors (above 0.94), good color rendering indexes (82-85), resistance to vibration, quick ignition and re-ignition times (under 1 second), and a rated life with U.S. test procedures of 100,000 hours, as compared with 24,000 hours for many fluorescent and high-intensity discharge (HID) lamps.

LED lighting

Light Emitting Diode (LED) systems are being used in traffic lights and information signs in the United States. Many exit signs in buildings have LED lighting systems that provide the illumination of the "EXIT" letters. They are much more energy efficient and have longer lives than incandescent lamps.

Other applications include walk/don't walk fixtures, display lighting, and facade lighting. Designers are now starting to use white LED lighting for indoor and general illumination activities.
