The Hot Series high bay design is built for temperatures up to 80°C (176°F). The innovative vertical flow cooling fin design and driver box allows the fixture to perform in harsh, extreme heat environments such as die-cast facilities, foundries, iron forges, steel mills, power generation, and chemical plants. Designed to replace 200W-400W HID / HPS / metal halide fixtures, the High Bay Hot delivers a long lifespan with minimal light decline.
