ZG2K is a new generation medium intensity OB light. It comes with compact-size and light-weight, which makes installation more convenience. The optical part is based on Fresnel lens, a transformed convex lens which can concentrate light to a small specific angel to meet with ICAO requirements. Fresnel lens is often used to design obstruction light. The light's ingress protection level is IP67, assures the light is well sealed to withstand harsh environment include the ocean. If work with control box, more functions like synchronization could be realized. GPS or GPRS functions also available if required. Medium intensity light ZG2K is designed for tower higher than 45m. It should be used either alone, or in combination with low-intensity light type B (our D32 series)
