Salt Lake City is switching to high efficiency LED street lights.
Salt Lake City will soon join the ranks of cities moving to LEDs to light city streets. Compared with traditional high pressure sodium (HPS) street lights, LEDs are more efficient, provide more uniform light distribution and increase light levels.

This LED uses just 6 watts.
As with other technologies, advances in lighting just keep coming. Now that you’re somewhat comfortable with CFL — compact fluorescent lamp — bulbs, get ready for things to change again. The latest generation of LEDs — light-emitting diodes — are here and manufacturers claim they rival the look, dimming ability, and light quality of incandescents. Better yet, LEDs contain no mercury, and last up to five times longer than CFLs and 50 times longer than incandescents. They are pricey, many sell for $60 or more, but could save about $300 in electrical cost over its life compared with an incandescent.

Who says it too expensive to change out the bulbs?
Not the Furniture Row Companies, a large family-owned retailer with 330 stores across the U.S., which is switching its showroom lighting to Cree Inc. LED lights
So far, Furniture Row has installed about 13,000 Cree LRP-38 LED spotlights, out of more than 80,000 planned, at its stores, which include the Sofa Mart®, Oak Express®, Bedroom Expressions® and Denver Mattress Company®.

OK, so you’ve done the environmentally correct thing and replaced most of your incandescent bulbs with CFLs (Compact Fluorescent Lightbulbs).
CFLs use less electricity and as a result, reduce greenhouse gas emissions. In an average home, lighting accounts for about a fifth of the electric bill. Because CFLs use about 75 percent less electricity than incandescent light bulbs — and last about 10 times longer, it just makes sense to switch.

San Francisco, the city that banned plastic bags, bottled water and Styrofoam, is taking another big step down the path to sustainable urban living. In March 2011, the City of San Francisco will begin installing more than 17,000 LED street lighting fixtures, effectively replacing most city-owned street lamps.

Deb Lovig’s official title at Cree, the lighting and semiconductor company, is “LED Programs Evangelist.” The description fits. Ask her to pick a favorite project and she’ll name five before you get
her stopped. She’ll skip from North Carolina State’s dorm lighting project (see picture, right) to the University of California-Davis’ smart parking garage to Notre Dame’s beautiful acorn-shaped fixtures without taking a breath.

From Green Right Now Reports:
Lighting and energy experts have been scratching their heads for sometime over how to make LED lighting as effective and pleasant as CFLs, because LEDs are even more energy efficient than CFLs.
Renaissance Lighting, based in Herndon, Va., appears to be inching forward in this effort. The company will be showcasing its new, all white solid-state LED downlight fixtures at the LIGHTFAIR International 2009 at the Javits Center in New York City. The new fixtures are brighter than ever and have two and half times greater efficacy.
