Where This Product Fits Best

This linear high bay is intended for large indoor spaces with high ceilings, such as warehouses, manufacturing plants, and distribution centers. It is suitable for areas where high lumen output and wide coverage are required.

The fixture is designed for environments where legacy 1000 Watt metal halide systems are being replaced. It is compatible with electrical systems operating at 277-480V.

Operating temperature range is -22°F to 113°F, supporting use in both conditioned and unconditioned spaces within this range.

Performance and Functional Considerations

The fixture provides 136 lumens per watt efficacy and a CRI of 80+, supporting accurate color rendering in work areas. The selectable color temperature allows adjustment between 4000K and 5000K to suit visual requirements or match existing lighting.

0-10V dimming is supported for integration with compatible dimming controls. The power factor is .98 and total harmonic distortion is 20% max, supporting stable operation on commercial electrical systems.

The frosted lens and 110 degree beam angle provide diffuse, wide-area illumination. The fixture is rated for 200,000 hours (L70), supporting long-term use with minimal maintenance.

Installation and Long-Term Use

Standard mounting is chain or cable. Pendant and surface mounting options are also available. The fixture's low profile and 46.5 inch length allow installation in spaces with limited vertical clearance.

The galvanized rolled iron housing is designed for durability in industrial settings. The fixture is suitable for installation in environments where exposure to dust, vibration, or temperature fluctuations is expected within the specified range.

No cord is included, so field wiring is required during installation. The fixture is designed for straightforward mounting and connection by qualified personnel.

How This Fixture Is Commonly Used

After installation, the selectable color temperature feature allows you to set the fixture to either 4000K or 5000K, depending on the visual needs of the space. This adjustment is typically made during commissioning and does not require ongoing changes.

The 0-10V dimming capability allows integration with compatible dimming systems, giving you control over light levels as needed for different tasks or occupancy patterns. The wide beam angle and frosted lens help reduce glare and provide even illumination across large floor areas.

Once installed, the fixture operates with minimal maintenance due to its long rated life. The galvanized housing supports reliable use in industrial environments where durability is a concern.
