With its record setting life span and light output, Lumingen Technologies’ SLD-HM Light Fixture is the obvious successor to the current generation of high mast luminaires. Utilizing the latest in LED technology and thermal dissipation systems, the SLD-HM HIGH OUTPUT SERIES has an L70 lifespan, delivered output, and efficacy that far exceeds any other high output luminaire. This is critically important in high mast applications such as roadway lighting, port/railway intermodal yard, sports field or airport lighting, which require high lumen output and long operating life.
