Pro-Series 4ft 400W Linear High Bay Factory

What is a 4ft 400W Linear High Bay?

The 4ft 400W linear high bay is the most powerful luminaire in our commercial lighting lineup. It is designed for extreme-scale indoor applications where ceiling heights exceed 40 feet, offering a heavy-duty, impact-resistant solution for the most demanding industrial environments.

1000W-1500W Metal Halide Replacement

This fixture is a formidable HID replacement, delivering up to 60,000 lumens while cutting energy costs by up to 75%. Whether for new construction or retrofitting aging T5HO fluorescent systems, this 400W aluminum high bay provides the punch needed for arenas, stadiums, and high-clearance logistics centers.

Technical Specifications: Pro-Series 4ft 400W Linear High Bay

Key Performance Features for High-Ceiling Projects

• Ultra-Bright 60,000 Lumen Output: Engineered to replace 1000W-1500W Metal Halide fixtures, providing exceptional light distribution for mounting heights up to 60 feet.

• Premium Aluminum Construction: Unlike standard steel fixtures, this 400W model utilizes high-grade aluminum materials to maximize heat dissipation, ensuring the LEDs and driver maintain optimal performance at peak wattage.

• Massive Field Flexibility: A true “All-in-One” solution with 3-step wattage selection (200W/300W/400W). Calibrate your light levels on-site to match the exact footcandle requirements of your facility.

• H-Type Balanced Architecture: The mid-mounted driver design creates a thermal barrier between the power source and LEDs while maintaining a perfectly level hanging profile for professional contractor installation.

Ideal Application Scenarios

Arenas, Gymnasiums, and Sports Facilities

The 400W aluminum housing is built for toughness and high-intensity output. Combined with a 5000K daylight setting, it provides the vibrant, shadow-free illumination required for high-speed sports and clear broadcasting.

High-Clearance Warehousing & Cold Storage

At mounting heights of 40-60 feet, light loss is a major concern. Our 150 lm/W efficacy ensures that light reaches the floor efficiently. The aluminum construction also performs exceptionally well in cold storage environments, providing instant-on performance without warm-up time.

Heavy Industrial & Manufacturing Plants

For facilities with dusty or high-vibration conditions, the sturdy construction and premium aluminum materials offer superior durability. The 4000K neutral white option is ideal for large-scale assembly where visual accuracy is critical.

Frequently Asked Questions (FAQ)

Q: Why is aluminum used for the 400W model instead of steel? At 400W, the fixture generates significant heat. Aluminum offers superior thermal conductivity compared to steel, allowing the fixture to dissipate heat faster. This protects the energy-efficient LED driver and ensures the LEDs don’t suffer from premature lumen depreciation.

Q: Is the 400W version too bright for lower ceilings? Because this fixture features wattage selectable technology, you can set it to 200W or 300W for lower ceilings (25-35ft) and only use the full 400W power for your highest mounting points. This makes it an incredibly versatile commercial fixture for mixed-height facilities.

Q: Does this fixture support smart controls for energy savings? Yes. Every unit is Controls Ready and 0-10V dimmable. It is compatible with motion sensors and daylight harvesting systems, which is often required to qualify for the highest DLC Premium utility rebates in North America.
