China LED Reuters] the U.S. Department of energy (DOE) released a report for the United States in Detroit, the existing high-pressure sodium street lights for LED street lamps to assess the effect.

Report conclusions:

Compared with the high-pressure sodium street lamp, the new LED street lamp to reduce energy consumption by about 4 million 600 thousand kwh of electricity per year (kWh), equivalent to about $2 million 900 thousand under the province.

The energy consumption and maintenance cost of the replacement of the province can only offset the accumulated cost of the LED street lamp, and the energy consumption of the province can be returned to about 2.5 years.

The new LED street light system should also be able to be more durable and to make the surrounding environment more secure, reduce the theft rate.

The lighting effect of the new lighting system is better than that of the traditional lighting system. However, due to the removal of many road lamps, the lighting quality of some residential areas is not so satisfactory.
