Description

LED roadway lighting GRL2 lamps are made of advanced LED refractive optical system and high-transmittance optical glass. The glass lens transmits all bands of light and reduces heat accumulation; using higher-efficiency 50505 and 7070 LEDs, the lamp beads generate less heat and more light; optimized for local roads, distribution roads and trunk roads. Modern thermoelectric design integrates the heat sink directly into the device for heat transfer, thereby extending the life of the LED.
