Fully-Switchable LED Center-Element Lay-in
Acuity Brands STACK Switch™ from Lithonia Lighting® is the fully switchable version of the next-generation family of lay-ins. With its three Adjustable Lumen Outputs (ALO) and three Switchable Color Temperatures (SWW) both conveniently located on the driver box, STACK Switch replaces the need to stock nine skews with just one! It represent one of the four performance-tiered solutions the STACK family brings to the market. The new aesthetic includes a wide, 7-inch curved lens which beautifully distributes the light, beveled end-plates to create a smooth transition from ceiling to light source, and less than 2 inches in total depth which makes it perfect for restricted plenum spaces.
