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.
