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 stairwell strip light delivers adjustable output from 22 to 44 watts with corresponding lumen output from 3102 to 6204 lumens. Color temperature is field-selectable between 3500K, 4000K, and 5000K. The fixture operates on 100-277V input and includes a built-in motion sensor that dims the light when no motion is detected.

The low-profile galvanized steel housing measures 46 7/8 inches by 2 1/2 inches by 2 11/16 inches and weighs 4.6 pounds. A frosted lens provides distributed light output with reduced glare across a 120-degree beam angle. This fixture is stairwell and passageway luminaire certified and serves as a direct replacement for fluorescent strip fixtures.

Where This Product Fits Best

This fixture is designed specifically for enclosed stairwells and passageways where code-compliant emergency egress lighting is required. The stairwell and passageway luminaire certification confirms the fixture meets the performance requirements for these applications. The built-in motion sensor allows the fixture to reduce output when spaces are unoccupied, which is common in stairwells that see intermittent traffic.

The 100-277V operating range accommodates both 120V and 277V circuits typically found in commercial and industrial buildings. Surface or wall mounting options allow installation on ceilings or walls depending on stairwell configuration and light distribution requirements.

Performance and Functional Considerations

Wattage selection at 22, 28, 36, or 44 watts produces 3102, 3948, 5076, or 6204 lumens respectively. The fixture maintains 141 lumens per watt across all output settings. Color rendering is 80+ CRI, which provides adequate color distinction for general circulation and egress applications.

The fixture accepts 1-10V dimming signals for integration with building lighting control systems. Power factor exceeds 0.90. Rated lifespan is 50,000 hours at L70, meaning the fixture will maintain at least 70 percent of initial light output at that point.

Installation and Long-Term Use

The fixture mounts to surfaces or walls using standard methods. Entry points on both the sides and ends of the housing allow electrical connections and enable multiple fixtures to be linked together and controlled from a single switch. No cord is included; direct wiring is required.

The galvanized steel housing and white finish are typical for stairwell environments where durability and light reflectance support visibility. At 4.6 pounds, the fixture is light enough for straightforward handling during installation or lamp maintenance.

How This Fixture Is Commonly Used

After installation, wattage and color temperature are set based on the stairwell dimensions and lighting requirements. Higher wattage settings work for taller stairwells or where brighter illumination is needed at landings. Lower settings may be appropriate for narrower passages or supplemental lighting.

Color temperature selection depends on the existing lighting in adjacent spaces or user preference. The 3500K setting provides warmer light, while 5000K produces cooler, more daylight-like output. Once set, these adjustments typically remain fixed unless building use or tenant requirements change. The motion sensor reduces output automatically when the space is unoccupied.

Safety, Certifications, and Warranty
