240 / 270 / 310 Wattage Adjustable Linear LED High Bay | 36000 to 46500 Lumens | 4000K / 5000K Color Adjustable | 100-277V or 277-480V | 1 Foot 9 Inches

Advanced High Bay Solution

For facilities that require maximum flexibility in their lighting systems, this adjustable linear LED high bay delivers three distinct wattage settings and dual color temperature options in a single fixture. Built for environments where lighting needs may evolve over time, the fixture provides 240, 270, or 310 watts of power while maintaining consistent 150 lumens per watt efficiency across all settings.

Engineered to handle demanding conditions in industrial and commercial spaces, this model produces between 36,000 and 46,500 lumens depending on the selected wattage configuration. With its specialized construction featuring die-cast aluminum housing and polycarbonate lens optics, the fixture delivers reliable illumination through a 90-degree beam angle suitable for general area lighting applications.

Comparing to Traditional Lighting

When upgrading from metal halide systems, this LED fixture replaces 1000-watt metal halide lamps while consuming significantly less energy. Unlike traditional lighting options that require lamp replacement and ballast maintenance, this LED solution operates for 50,000 hours with minimal degradation. By comparison, the instant-on capability eliminates warm-up time, while the adjustable wattage feature allows operators to fine-tune energy consumption based on actual facility requirements rather than being locked into fixed output levels.

Operational Advantages

Energy Usage

What makes this fixture valuable for buyers is the ability to adjust power consumption between 240 and 310 watts without changing the fixture itself. From a cost standpoint, this flexibility enables operators to optimize energy usage for specific areas while maintaining consistent light quality. The high power factor of 0.90 and low total harmonic distortion of 20% maximum ensures efficient operation that won't stress electrical systems.

Visibility

In real-world use, the color temperature adjustment between 4000K and 5000K allows customization of the visual environment without fixture replacement. The 80+ CRI rating ensures accurate color rendering for detailed work, while the polycarbonate lens provides even light distribution across the coverage area. Additionally, the 0-10V dimming capability supports daylight harvesting and occupancy-based lighting strategies.

Durability

Built with die-cast aluminum construction, this fixture withstands temperature extremes from -40°F to 122°F while maintaining performance. In practice, the 10kV surge protection guards against electrical transients common in industrial environments. Performance-wise, the 50,000-hour L70 rating means the fixture will maintain at least 70% of initial light output after five decades of operation, reducing maintenance interventions significantly.
