Performance & Light Output

Engineered for maximum adaptability, this 3-foot high bay delivers up to 64,000 lumens of brilliant illumination. The standout feature is the OpticSwap multi-function lens system, which allows users to easily shift between a 90-degree standard beam for open area illumination and a 45x110-degree aisle beam for focused, narrow corridors by simply rotating the installed lens. With selectable 4000K and 5000K color temperatures and an 80+ CRI, it ensures optimal visibility. The high-performance LEDs guarantee long-term reliability with an L70 lifespan of 100,000 hours.

Electrical & Controls

This luminaire features a universal 120-277V driver equipped with 0-10V dimming capabilities for seamless integration with commercial energy management systems. The intelligent design includes a dedicated twist-in sensor receptacle, making it incredibly easy to upgrade. Installers can quickly connect compatible Keystone SmartPort or SmartLoop microwave and PIR motion sensors (sold separately) to automate lighting schedules and maximize energy efficiency without complex internal wiring.

Construction & Durability

Built to endure demanding commercial environments, the fixture features a robust metal chassis with advanced heat transfer technology to properly manage LED thermal limits at high outputs. The OpticSwap lens system is secured via simple clasps, allowing tool-free adjustments while maintaining a secure fit. The luminaire is UL Listed for damp locations, protecting the internal electronics from ambient moisture commonly found in unconditioned industrial facilities.

Installation & Mounting

Designed for rapid deployment, this 3-foot linear high bay supports standard suspended mounting suitable for a wide range of high-ceiling architectures. The field-adjustable wattage and CCT switches are positioned for easy access, allowing electrical contractors to quickly configure the fixture on-site. For standard hanging requirements, compatible V-hooks and chains are included, while optional surface mount kits and pendant mounting accessories (sold separately) can be utilized to achieve the perfect orientation.
