About this item

  • Ballast Bypass Type B Design: This LED high bay retrofit light is engineered with a true Type B ballast bypass system, meaning it must be wired directly to line voltage and should never be used with an existing ballast. This design improves overall safety, eliminates ballast-related failures, reduces maintenance costs, and ensures consistent long-term performance in commercial and industrial environments.
  • High Lumen Output and Energy Efficiency: Delivering an impressive 21,000 lumens while consuming only 155 watts, this LED high bay provides powerful illumination with significantly lower energy usage compared to traditional HID or metal halide fixtures. It is ideal for large spaces that require bright, uniform lighting while helping reduce electricity costs and improve operational efficiency.
  • Bright White 5000K Light with Wide Beam Angle: The 5000K bright white color temperature produces clean, daylight-like illumination that enhances visibility, accuracy, and safety in workspaces. Combined with a wide 120° beam angle, the light is evenly distributed across large areas, minimizing shadows and dark spots in warehouses, factories, and workshops.
  • Flexible Installation with EX39 Base: Designed with an EX39 base, this retrofit LED high bay allows for straightforward installation in compatible fixtures and supports both base-up and base-down orientations. This flexibility makes it suitable for a wide range of mounting configurations, simplifying upgrades from older high-intensity discharge lamps.
  • Durable Construction for Commercial and Industrial Use: Rated for dry and damp locations, this LED high bay retrofit is built to withstand demanding environments such as warehouses, barns, garages, and industrial facilities. Operating on a wide voltage range of 100–277 VAC and featuring a non-dimmable, stable output, it delivers reliable performance, long lifespan, and reduced maintenance needs for heavy-duty applications.
  • The Diodesy LED High Bay Retrofit Light Type B is a powerful and efficient lighting solution designed for demanding commercial and industrial environments. Featuring a true ballast bypass design, this fixture is not for use with any ballast and must be wired directly to line voltage for safe and reliable operation. Engineered for both base up and base down installations, this LED high bay offers flexible mounting options to suit a wide range of applications. With a high output of 155W and an impressive 21,000 lumens, it delivers bright, uniform illumination ideal for large open spaces. The 5000K bright white color temperature provides crisp, daylight-like lighting that enhances visibility, productivity, and safety in work areas. Equipped with an EX39 base, this retrofit lamp is designed to replace traditional HID lamps with ease while significantly reducing energy consumption.
