The United States found that the LED light is not suitable for extreme desert climate

In Tempe, Arizona that LED is not suitable for extreme desert climate in the region, the United States Lighting Technology Co. Ltd. announced that it will provide 1000 induction to the city street lamp.

Tempe, Arizona started a street lighting system renovation project, and select the induction lamp, but not solid lighting based on LED (SSL), (HPS) to replace the high-pressure sodium lamp and metal halide lamp (MH). Lighting technology company announced that it will provide 1000 lights to the city to save energy, to save up to 40% of energy consumption. It is clear that the city does not think the LED lamp is suitable for extreme desert climate in the southwest of the region. The United States lighting technology company executive vice president Alexander Ham said: "in the street and LED on the induction of the two main street lamp lighting evaluation and comparison, because of the expensive cost of equipment and the LED lamp in Southern Arizona, extreme climate unstable performance factors considered, Tempe, chose to give up LED lights".

Of course, other cities and public facilities to choose the induction lamp rather than LED based solid state lighting, mainly due to the lower input costs of induction lamps. Whether the factors that hinder the development of LED are climate factors, is still a question. It is well known that the design of lamps must be able to conduct heat in a reliable manner. However, compared with the low temperatures in the southwest desert night, LED lamps in the high temperature region more reliable performance. Of course, induction lighting technology can really save energy than traditional technology. American Lighting Technology Co., Ltd. will provide the city of 70W Cobra 100 series lamps to replace 125W high pressure sodium lamp or metal halide lamp. Induction lamps do not have the ability to fine tune light, and LED lights can be further reduced by adaptive control of energy consumption.

Bad LED experience in Columbo, Ohio

Under normal circumstances, in addition to the early cost is too large, LED street lamps will usually get rave reviews. But according to a report on the LED street lamp test by The Columbus Dispatch, Columbo, Ohio, is an exception. The newspaper reported that some LED energy-saving lamps installed within two months after the test did not pass.

In Ohio, Dublin, has allocated $500 thousand and will use LED technology, the transformation of 1500 street lamps. Dublin test results show that the use of LED lights can reduce energy consumption by 40% to 50%.

Iowa and Mississippi pilot LED street lamp

LED street lights and space lighting is continuing to promote in most parts of the United states. The Des Moines Register reported that the Iowa Valley Junction park is Iowa City Lighting System Based on LED, the city will complete the LED lamp in the autumn of this year's installation, in order to save lighting energy consumption 50%. In addition, the city will serve as a pilot project for the entire Valley Junction park lighting system transformation. Mississippi County, the installation of the LED lamp Rankine solar power, solar lighting alliance also announced the first guidance document.
