The new Etlin-Daniels STL54S-M50WLCO-WH 4-foot LED Strip fixture offers the latest in quality, internal multi-features, and performance. With its new slimmer design, the STL54S has external and easily accessible switches that provide for selecting between 30W, 40W, and 50W, and also, a 3CCT switch allowing for a choice between 3500K, 4000K, and 5000K. The driver offers 2 forms of control – it is equipped with available 0-10 Continuous Dimming, and also has 2 low voltage wires and an Auxiliary Port that provide for the installation of an Internal Microwave Sensor option – STL5S-SENMC-12V. The high efficacy of 130lm/w allows for superior energy savings and the frosted lens delivers even and glare-free illumination. End knockouts provide continuous row mounting – using the STL5S-CB Corner Brackets – and wire guards are available to protect from physical shock. An innovative and easy-to-install j-box cover comes with each fixture to ensure that all wires are properly protected and the proper aesthetic is maintained. • LED Indoor Light Source • Light weight powder coated metal housing with frosted glare free lens • Fixtures can be surface or suspension mounted • End knockouts for continuous mounting. • 120-347V • Damp location rated • Multi-Wattage Switching – 30W / 40W / 50W 3CCT – 3500K / 4000K / 5000K • Optional internal Microwave Sensor option • J-box covers included • Wire guards available • 0-10V Continuous Dimming • L70 – 100,000 hours • DLC certified
