）,researchers at the Lighting Research Center at Rensselaer Polytechnic Institute in Troy, New York, said they had boosted the light output per watt of a white LED to almost six times that of an incandescent light bulb, beating even a compact fluorescent bulb in efficiency. （http://www.hindustantimes.com/news/181_1325226,001100050011.htm）

寿命5~10 年。价格是老式灯泡的5~10倍。 外壳强度大。运输损耗极小， 户外维护极小。

很能满足上海市政府的灯光工程。

那位能帮忙翻译下面的文章， 写得挺全。 我打字太慢。有一点：现在LED价格降得挺快， 因为中国产量比重越来越大。

The new lighting technology would also dramatically cut electricity demand. According to a study commissioned by the U.S. Department of Energy, widespread adoption of next-generation white LEDs for lighting could, by 2025, slash electricity consumption by 10 percent worldwide, cutting $100 billion per year from electric bills and saving $50 billion in averted power-plant construction costs. "Lighting is a major contributor to the use of electricity. Collectively we could save half the energy we use on lighting," says George Craford, chief technology officer at Lumileds. "Make lighting more efficient and the question of building new power plants starts to go away." （from: http://cache.technologyreview.com/articles/03/05/talbot0503.asp?p=1)
