22 to 44 Watt Power & Color Adjustable 4 Foot LED Stairwell Strip Light | 3102 to 6204 Lumens | 3500K to 5000K | 100-277V | Motion Sensor

Product Overview

This 4-foot LED strip light delivers adjustable output from 30 to 50 watts with corresponding lumen output of 4,200 to 7,000 lumens. The fixture maintains 140 lumens per watt across all wattage settings. Color temperature is selectable between 3500K, 4000K, and 5000K.

The galvanized steel housing measures 48 x 3 x 3 inches and weighs 4.3 pounds. A frosted polycarbonate lens provides 120-degree beam distribution. The fixture operates on 100-277V input at 50-60Hz with a power factor greater than 0.90.

This fixture is designed as a direct replacement for fluorescent strip lights. It supports both chain-cable and surface mounting configurations. The housing finish is white.

Where This Product Fits Best

This strip light fits applications where fluorescent strips are currently installed or specified. The 4-foot form factor and dual mounting options allow installation in the same locations as legacy T8 or T12 fluorescent strip fixtures.

The operating temperature range of -4°F to 122°F supports use in conditioned and semi-conditioned spaces. The 100-277V input accepts standard commercial voltage systems without external transformers.

Typical fit includes back-of-house areas, utility corridors, storage rooms, mechanical spaces, stairwells, and general-purpose overhead lighting where strip-style fixtures are appropriate.

Performance and Functional Considerations

Output selection between 30, 40, and 50 watts allows the same fixture to serve different spacing requirements or light level targets. Lumen output scales directly with wattage: 4,200 lumens at 30 watts, 5,600 lumens at 40 watts, and 7,000 lumens at 50 watts.

Color temperature selection between 3500K, 4000K, and 5000K allows visual appearance to be matched to adjacent fixtures or space requirements. CRI is rated at 80 or higher.

The fixture supports 1-10V dimming for integration with compatible building controls or wall dimmers. Rated lifespan is 50,000 hours at L70.

Installation and Long-Term Use

The fixture accepts chain-cable suspension or direct surface mounting. No power cord is included, so field wiring is required. The galvanized steel housing resists corrosion in standard indoor environments.

Wattage and color temperature adjustments are made at the fixture. Once set, the fixture operates at the selected output and color without further adjustment unless changed intentionally.

At 4.3 pounds, the fixture is manageable for single-person installation in most ceiling configurations. The 4-foot length aligns with standard ceiling grid and joist spacing.

How This Fixture Is Commonly Used

Facilities replacing fluorescent strips use this fixture to maintain existing mounting locations and general light distribution while eliminating lamp and ballast maintenance. The adjustable wattage allows light output to be tailored to the specific area after installation.

Color temperature selection is typically set during commissioning to match adjacent areas or meet visual preference. Spaces with mixed lighting often benefit from the 4000K setting, while warmer environments may use 3500K and task-oriented spaces may use 5000K.

The 1-10V dimming input allows connection to building automation systems or manual dimmers where occupancy-based or daylight-responsive control is in place.
