The High Bay Hot Series by Red Sky Lighting is a premium lighting solution purpose-built for high-temperature industrial environments. Engineered for exceptional durability and performance, this series has undergone rigorous testing and is UL verified to deliver outstanding lumen maintenance. Even after 10,000 hours of continuous operation at an ambient temperature of 176°F (80°C), the fixture retains up to 95.9% of its initial light output. Pushing the limits of endurance even further, the High Bay Hot Series maintains at least 70% of its original brightness even after 47,000 to 50,000 hours of non-stop use under the same extreme conditions. This ensures more than five years of 24/7 operational life or over a decade of service when used 12 hours a day—making it a reliable and cost-effective choice for the most demanding applications.
Built for industrial sectors like metal processing, pulp and paper, wood manufacturing, and high bay or low bay environments, the High Bay Hot Series thrives in punishing heat and harsh surroundings. The fixture is housed in a heavy-duty anodized aluminum body that offers superior corrosion resistance, complemented by a vertical cooling fin structure and a thermally isolated driver compartment. These features allow it to withstand the intense operating conditions found in die casting plants, steelworks, ironmaking facilities, power stations, and chemical plants.
This series comes rated for UL 1598 Wet Locations, withstanding IP66/IP67 levels of ingress protection and meeting IK08 impact resistance and 5G vibration standards, making it suitable for use in physically and environmentally demanding locations. Certified under UL1598, UL8750, CSA C22.2 No. 250.0-08, CSA C22.2 No. 250.13-14, and V-mark, the product is also pending DLC certification, signaling energy-efficient credibility.
Performance is equally impressive: the High Bay Hot Series delivers a high lumen output of 22,158 lumens at an efficacy of 150 lumens per watt, with 60° or 110° beam angles available to suit various installation requirements. The color temperature is a crisp 5000K, delivering bright daylight-quality light with a Color Rendering Index (CRI) of Ra≥70, suitable for visual clarity in industrial workspaces.
With a power rating of 150W, the luminaire supports a wide input voltage range of 120-277V AC and 347-480V AC, operating efficiently on both 50Hz and 60Hz power supplies. The power factor exceeds 0.90, and Total Harmonic Distortion (THD) is kept under 20%, ensuring electrical system compatibility. The fixture boasts an extraordinary L70 lifespan of 130,000 hours at 176°F, made even more reliable by its robust surge protection system (12-18AWG, rated to 105°C).
Backing its unmatched reliability is Red Sky Lighting’s five-year no-compromise warranty, covering every component—from the LEDs and driver to the housing and gaskets. With its high lumen output, remarkable thermal endurance, and industrial-grade construction, the High Bay Hot Series is an ideal solution for facilities that demand peak lighting performance under the most extreme conditions.
