High Power LED Street Light, is a new, energy-saving product that utilizes high power led's as light source, it can be directly connected with a 85-264VAC power supply and can also be powered with the optional solar panel kit. The LED color spectrum, there is no ultraviolet light, no infrared rays, no heat, and no radiation produced. As a result, our LED Street Light series is a conventional "green" lighting source. The lamp casing is made of aluminum-alloy through die-casting that is covered with fluorocarbon powder that is sprayed in electrostatic sprayed. The LED Street Light lamp lens is made of material that use high quality transparent polycarbonate, is highly lucent, dust-proof, and waterproof. Our whole set LED Street Light uses Aluminum for fasteners, the product is safe, reliable, and has low energy-consumption and a long life span. S1 LED Street Light, it is especially suitable to use in public places such as open squares, streets, and roads. As a professional LED Street Light Manufacturer, Supplier and Exporter, most of LED Street Lights got the CE, RoHS, UL certificates once we inverted, also, you an customize your branded LED Street Light, feel free to tell us, call us NOW

A light-emitting diode (LED) (pronounced /eliːˈdiː/[1], or just /led/), is an electronic light source. The first LED was built in the 1920s by Oleg Vladimirovich Losev, a radio technician who noticed that diodes used in radio receivers emitted light when current was passed through them. The LED was introduced as a practical electronic component in 1962. All early devices emitted low-intensity red light, but modern LEDs are available across the visible, ultraviolet and infra red wavelengths, with very high brightness. LEDs are based on the semiconductor diode. When the diode is forward biased (switched on), electrons are able to recombine with holes and energy is released in the form of light. This effect is called electroluminescence and the color of the light is determined by the energy gap of the semiconductor. The LED is usually small in area (less than 1 mm²) with integrated optical components to shape its radiation pattern and assist in reflection. LEDs present many advantages over traditional light sources including lower energy consumption, longer lifetime, improved robustness, smaller size and faster switching. However, they are relatively expensive and require more precise current and heat management than traditional light sources.

CFL is expensive compared to Incandescent the same way LED is expensive compared to CFL. CFL contains Mercury which is a hazardous substance. So, LED is way better from CFL. It's demand and market that will drive the cost. Govt. should issue subsidies to LED lighting. Besides when people can afford to by expensive cars and build expensive homes.. price od LED’s are negligible. Once this market flourishes the price will drop for other ordinary and upper class market to afford them as well. Govt. can also pass a bill to enforce industries and commercial buildings to full 25% or so energy needs via LED. In the state of Oregon, US something like this has already been enforced where new companies have to substitute 25% of their electricity needs via renewable energy. Forget Oregon, right here in Karnataka any new houses above 1200 sq ft has to have mandatory solar water heaters, So, the cost maybe high but if there is commitment, it's possible to bring it mainstream.

When trying to determine the greenest option among products, it is important to take into account the whole life-cycle of the thing; the manufacturing process, how it is used, and the disposal at the end of its life. The U.S. Department of Energy has already released a few life-cycle assessments (LCA) of LED lights (see here and here for a Carnegie Mellon study), and LED maker Osram has just released a new LCA study conducted by the Siemens Corporate Technology Centre for Eco Innovations. Their conclusions are pretty interesting... Both the Carnegie Mellon and Osram studies found that production is a relatively small portion of the total life-cycle impact of the different lightbulb technologies. From the Osram study: "[with LEDs and CFLs] over 98% of the energy used is consumed to generate light. Less than two percent is allocated to production. This dismisses any concern that manufacturing of LED particularly might be very energy-intensive." When comparing LEDs that produce about 30 lumens/watt to CFLs, the results are very close, and for all practical purposes, we can say that LEDs are as energy efficient as CFLs. But LEDs are still improving and they do not contain mercury, which makes their disposal less hazardous than CFLs. The Carnegie Mellon study predicts that efficiencies of 150 lumens/watt are possible for This would make LEDs take a significant lead and assure their dominance over CFLs, as long as prices can be brought down. Even if 150 lumens/watt isn't attainable in the near future, a doubling to 60 lumens/watt would leave CFLs in the dust.
