the service life of the products will greatly extend

For replacing convenitional 400w high voltage sodium lamps; 60 units of LATTICELIGHTING LLRA120 LED street lights have been installed along the 3 roads in Qian Hu campus of Nanchang University. All these street lights have the average illuminance 28 lux, reaching the standard of city road illumination ME2. The installation of these lanterns can reduce power consumption by 60% and save energy by 2/3. Also dimming technique is applied to each led high bay light, enabling each lantern to reduce automatically power consumption to a reasonable level at night when there are few pedestrians and vehicles. Due to constant control by the electronic appliance, lamps and lanterns, drivers as well as the electronic appliance can operate continuously and steadily even under conditions of voltage and current below rated ones. Thus, the service life of the products will greatly extend.
