4ft 300W Linear High Bay Fixture Supplier

What is a 4ft 300W Linear High Bay?

The 4ft 300W linear high bay is the ultimate professional lighting solution designed for large indoor spaces with high ceilings. Its elongated 4-foot frame and wide-body design ensure broad, uniform light distribution, making it far superior to traditional point-source fixtures in minimizing shadows across expansive facilities.

1000W Metal Halide (MH) Equivalent Performance

This fixture is known as the “T5 Killer” and “HID Replacement” powerhouse. At its full 300W setting, it delivers up to 45,000 lumens, allowing it to easily replace a 1000W Metal Halide or 8-10 lamp T5HO fluorescent system. This upgrade provides immediate energy savings while significantly improving the light quality and footcandle levels on the ground.

Key Features and Benefits

High Lumen Output and Efficiency

With an efficacy of up to 150 lm/W, this fixture delivers crisp, bright light while using minimal power. The 300W output ensures that even when mounted at heights over 30 feet, the light reaches the floor with high-intensity clarity, perfect for precision manufacturing or professional gymnasiums.

Durable Construction and Heat Dissipation

Constructed from heavy-duty cold rolled steel with an H-Type structural design, the fixture features a center-mounted driver. This architecture physically separates the driver from the LED boards, promoting superior airflow and heat dissipation. This sturdy construction prevents heat build-up, ensuring the longevity of the energy-efficient LED driver.

Energy Savings and Maintenance Reduction

By switching to this dimmable LED fixture, facility managers can reduce energy consumption by over 60%. Combined with a rated life of over 54,000 hours, it eliminates the need for frequent bulb or ballast replacements, drastically cutting long-term maintenance costs.

Ideal Application Scenarios

Warehouse and Industrial Facility Lighting

Ideal for massive logistics centers and high-rack storage. The wide beam spread ensures that vertical light reaches the highest shelves, while the high lumen output provides a safe environment for high-speed forklift operations.

Commercial Retail and Gymnasiums

The professional white powder-coated finish and anti-glare frosted lens make it a top choice for commercial lighting in big-box retail, supermarkets, and sports arenas. It delivers daylight-quality illumination without the harsh glare that distracts athletes or shoppers.

Workshops and Manufacturing Plants

For heavy industrial LED light needs, the 4000K neutral white setting provides excellent task visibility, reducing worker fatigue and improving overall production accuracy in assembly plants and workshops.

Frequently Asked Questions (FAQ)

Q: Can I adjust the brightness after installation? Yes. This fixture features wattage selectable technology (150W/225W/300W), allowing you to change the power output on-site if the lighting needs of the space change. It also supports 0-10V smooth dimming for integration with smart controls.

Q: What is the benefit of the wide-body 17.3″ design? The wider 17.3-inch frame provides a larger luminous surface area. This reduces “pixelation” and glare, creating a much more comfortable visual environment than narrower, high-intensity fixtures.

Q: Does this fixture support motion sensors? Absolutely. It is Controls Ready and can be equipped with an optional microwave motion sensor. This is highly recommended for warehouse lighting to maximize energy savings by dimming the lights when aisles are unoccupied.
