Firstly, about the energy saving. LED outdoor lights are at least five times more efficient than traditional incandescent bulbs and 65% more efficient than fluorescent tubes. These savings can be particularly significant external illumination, typically left running for a long time.

　　Secondly, LED light generated by the system the quantity and quality significantly better than traditional lighting technology. This may improve the safety of pedestrians and drivers, as well as to improve the appearance of public spaces.

Thirdly, LED lamps have a typical life of more than six years continuous use, which is substantially longer than conventional technologies. This ensures considerable savings in replacement and maintenance costs, particularly as outside lighting can often be difficult or dangerous to reach. It also improves safety levels because the lighting is less likely to fail in critical areas.

Therefore, it is no surprise to find that compensate for external application of LED lighting applications of the fastest growing markets in the world. For example, better BP gas station in Racine, Wisconsin, all exterior lighting LED. Bright white light, and enhance the appearance of the front yard, is pulling customers while at the same time provide substantial energy savings of 62%.

In addition, more and more educational institutions use LED lighting to illuminate outdoor spaces. For example: In the Prairie School, Wisconsin parking LED lights in the University of California, Santa Barbara, and LED lights in China, Tianjin Polytechnic University. A larger LED City initiative underway, we encourage local governments to adopt LED outdoor lighting, and its external space with LED lighting. It was founded in February 2007, Raleigh, North Carolina, a pilot project. This installation in a garage is to provide a 40% energy saving, the public has responded positively garage excellent quality of lighting.

In Ann Arbor, Michigan with 1000 LED lights are also installed in the two years to join LED City program. This is expected to save energy 50%, the payback period is 3.8 years.

The plan in other cities including Toronto, Ontario and Austin, Texas. The latter is trying a garage and street lighting applications technology, and Joe, Toronto Deputy Mayor Pantalone, see a very bright future for the LED.
