Litetronics SWFS4 4' LED Stairwell Fixture

The Litetronics SWFS4 is a 4-foot LED stairwell fixture designed to provide efficient, low-maintenance lighting for limited-use spaces such as stairwells. Built as a linear, surface- or suspension-mounted solution, its two-piece construction supports quick installation and flexible mounting options, including t-grid compatibility to fit a variety of ceiling configurations. The unit integrates a microwave occupancy sensor and daylight sensor to automatically adjust lumen output based on occupancy and ambient light levels, helping to reduce energy consumption in spaces with intermittent use.

Key construction and performance details include a 4-foot form factor, 120–277 V operation, and an average rated life of 100,000 hours, which are important for evaluating long-term maintenance needs and expected replacement intervals in facility environments. The fixture supports dimming and is compatible with DLC Premium requirements and FCC standards, aligning with common energy and performance criteria used in building projects. Its adjustable color temperature and wattage settings provide installers with the ability to tailor brightness and output to the specific stairwell application, improving visual comfort and energy efficiency.

This fixture is suitable for stairwells and other limited-use corridors where reliable, automatically controlled lighting is beneficial. The design supports various mounting configurations for retrofit or new construction, and its rugged performance temperature range from -4°F to 113°F makes it adaptable to diverse environments. The product is sold in an individual package, suitable for projects of varying sizes, and the 10-year warranty offers long-term assurance on performance and support. Units should be installed according to local electrical codes and fixture manufacturer recommendations to maximize the benefits of its sensor-driven controls and dimming capabilities.
