400 Watt LED High Temperature Light | 52000 Lumens | 5000K | 100V-277V or 347V-480V | Rated to 194F

Product Overview

This is a 400 watt LED high bay fixture designed for commercial and industrial applications requiring high output and robust construction. It delivers 52,000 lumens at 130 lumens per watt and is intended as a direct replacement for 1000 watt metal halide systems.

The fixture is available in 4000K or 5000K color temperatures and offers a CRI of 80+. It supports both 100V-277V and 347V-480V input ranges, making it compatible with a wide range of electrical systems.

Beam angle options include 10°, 25°, 40°, 90°, and 120°, allowing for precise control over light distribution. The fixture uses a polycarbonate lens and is finished in gray.

It is built with an aluminum alloy housing and weighs 45.8 lbs. Dimensions are 22 x 20.86 x 8.65 inches.

Where This Product Fits Best

This fixture is suited for large indoor spaces where high lumen output and directional control are required. Typical environments include warehouses, manufacturing plants, distribution centers, and sports venues.

It is designed for locations where legacy 1000 watt metal halide fixtures are being replaced and where a robust, sealed fixture is needed to withstand challenging conditions.

The wide voltage compatibility supports both standard and high-voltage installations. The available beam angles allow adaptation to different mounting heights and lighting layouts.

Use in areas where exposure to dust, moisture, or temperature extremes is expected is supported by the fixture's IP66 rating and broad operating temperature range.

Performance and Functional Considerations

The fixture provides 52,000 lumens with a power factor greater than 0.95 and total harmonic distortion below 15%. It operates at 50/60 Hz and is rated for a 70,000 hour lifespan.

There is no dimming capability. Output is fixed at the selected wattage and color temperature.

Beam angle selection allows for control over light spread, from narrow spot (10°) to wide flood (120°). This supports both focused and general area lighting needs.

The polycarbonate lens and aluminum alloy housing contribute to impact resistance and durability in demanding environments.

Installation and Long-Term Use

Mounting options include eye-hook and pendant, supporting both chain/cable and rigid installations. The fixture's weight and size should be considered when planning mounting hardware and support structures.

The IP66 rating allows for installation in areas exposed to dust and water jets. The fixture operates reliably in temperatures from -40°F to 194°F.

Maintenance requirements are reduced by the long rated lifespan and sealed construction. The fixture is designed for minimal intervention after installation.

Electrical compatibility with both 100V-277V and 347V-480V systems allows use in a variety of facility power configurations without modification.

How This Fixture Is Commonly Used

After installation, the fixture provides consistent, high-output illumination with no need for dimming or adjustment. The selected beam angle determines how focused or wide the light pattern is in the space.

Operators can rely on the fixture for stable performance in environments with dust, moisture, or temperature swings. The sealed housing and polycarbonate lens help prevent ingress and damage.

Once mounted, the fixture requires little ongoing attention aside from periodic inspection. The fixed output and color temperature simplify day-to-day operation.

In retrofit scenarios, this fixture is used to replace 1000 watt metal halide units, reducing maintenance and providing immediate full output on power-up.
