270 / 340 / 400 Wattage Adjustable High Bay Linear | 41600 to 54100 Lumens | 4000K / 5000K Adjustable | 100-277V | 3 Foot 8 Inches

Product Overview

This 3-foot 8-inch linear high bay delivers field-adjustable output from 270 to 400 watts, producing 41,600 to 56,100 lumens at 150 lumens per watt. The fixture replaces 1000W, 1500W, or 2000W metal halide systems depending on the wattage setting selected. Color temperature is adjustable between 4000K and 5000K, and the fixture operates on 100-277V input at 50/60 Hz.

The housing is galvanized rolled iron with a white finish and a polycarbonate lens providing a 90-degree beam angle. The fixture weighs 10 pounds with dimensions of 44.2 x 10.2 x 1.8 inches. Rated lifespan is 70,000 hours with a CRI of 80+.

Where This Product Fits Best

This linear high bay fits applications where high-output metal halide fixtures are currently installed and replacement with equivalent or greater lumen output is required. The wattage range covers replacement of 1000W through 2000W metal halide, making it appropriate for facilities with varying legacy fixture sizes across different zones.

The operating temperature range of -4°F to 122°F supports use in conditioned and unconditioned spaces, including cold storage entries, loading docks, and manufacturing areas with elevated ambient temperatures. The 100-277V input handles standard commercial and industrial electrical systems without requiring transformers or voltage matching.

Performance and Functional Considerations

At 150 lumens per watt across all three wattage settings, efficiency remains consistent whether operating at 270W, 340W, or 400W. The fixture supports 0-10V dimming for integration with building automation or manual dimmer controls.

Power factor is rated at .98 with total harmonic distortion at 20% maximum. The 90-degree beam angle from the polycarbonate lens produces a broad distribution pattern typical of linear high bay applications. The 70,000-hour rated lifespan reduces relamp frequency compared to metal halide systems.

Installation and Long-Term Use

Mounting options include chain-cable (standard), pendant, or surface configurations. The fixture ships without a cord, so field wiring is required. At 10 pounds and 44.2 inches in length, handling during installation is manageable for single-person mounting in most configurations.

Wattage and color temperature adjustments are made at the fixture. Once set, the fixture operates at the selected output without further intervention. The galvanized rolled iron housing resists corrosion in typical indoor industrial environments.

How This Fixture Is Commonly Used

Wattage selection is typically determined during initial installation based on the output of the fixture being replaced or the light levels required for the space. Facilities replacing mixed metal halide wattages across a single building can configure each fixture to match the output needed for that specific location.

Color temperature selection between 4000K and 5000K is usually made based on task requirements or visual preference. Areas requiring color accuracy or detail inspection often use 5000K, while general circulation and storage areas may use 4000K for a warmer appearance. Once configured, the fixture requires no regular user interaction beyond cleaning and eventual replacement at end of life.
