320 / 400 / 500 Watt Adjustable Linear LED High Bay Light | 48960 to 76900 Lumens | 3500K / 4000K / 5000K Adjustable | 100-277V | 3 Foot 4 Inches

High-Performance Adjustable Linear LED High Bay

Built for environments where flexibility and performance are critical, this adjustable linear LED high bay delivers exceptional lighting control across demanding industrial applications. Engineered to handle varying operational requirements, the fixture provides three distinct wattage settings and color temperature options in a single unit. With its aluminum alloy construction and wide voltage compatibility, this lighting solution addresses the complex needs of facilities requiring adaptable illumination without compromising on efficiency or durability.

Key Advantages

• Triple wattage flexibility allows on-site adjustment between 320W, 400W, and 500W settings
• Delivers up to 76,900 lumens while maintaining consistent 150 lumens per watt efficiency
• Color temperature adjustability provides 3500K, 4000K, or 5000K options for optimal visibility
• 1-10V dimming capability enables precise light level control for energy optimization
• 100,000-hour L70 lifespan reduces maintenance frequency and operational costs
• Wide 100-277V input voltage accommodates diverse electrical systems
• Compact 39.5-inch linear profile maximizes coverage while minimizing installation complexity

Who This Fixture Is For

• Manufacturing facilities requiring variable lighting levels for different production shifts
• Warehouses and distribution centers with mixed-use zones needing flexible illumination
• Retail operations seeking to optimize lighting conditions for merchandise display
• Sports facilities requiring adjustable lighting for various activities and events
• Educational institutions with multipurpose spaces demanding versatile lighting solutions
• Maintenance teams looking to standardize inventory with single adjustable fixtures

How It Compares to Metal Halide

When upgrading from metal halide systems, this LED fixture provides immediate operational advantages through its adjustable functionality. Unlike traditional 1500-watt metal halide fixtures that operate at fixed output levels, this LED solution allows real-time adjustment of both wattage and color temperature to match specific application requirements. The instant-on capability eliminates warm-up delays, while the extended 100,000-hour lifespan dramatically reduces the frequent relamping associated with metal halide technology. Additionally, the consistent light output throughout the fixture's operational life contrasts sharply with the gradual degradation typical of metal halide systems.

Installation Considerations

For most installations, the standard chain-cable mounting system provides straightforward deployment in facilities with existing suspension points. The surface mounting option offers flexibility for applications requiring direct ceiling attachment or specialized positioning requirements. At 14.6 pounds, the fixture's moderate weight simplifies handling during installation while the universal 100-277V input voltage eliminates the need for specific electrical modifications. From a planning perspective, the fixture's cordless design requires proper junction box positioning, and the 1-10V dimming functionality will need compatible control wiring for full operational capability.
