Features Self-developed J-lights: small optical decline, high illumination level, high efficiency and good heat dissipation. Distribution of light: the bat-wing distribution curve has passed the detection of "National Electric Light Source Quality Supervision and Inspection Center" and met the requirement of "city road lighting design standards." Heat dissipation technology: radiator is extruded by high thermal conductivity aluminum and the air contact area is 0.8 square meters, and form a good air convection. The working temperature does not exceed 60 °C, ensuring the stability and long life of the lamps. Up to 30,000 hours service life. The brightness of J-1300W streetlight equals to that of 400W traditional high pressure sodium lamp. Light source service life is up to 30,000 hours. For main roads, secondary roads, trunk roads and other support designed for road lighting.
