The 4in Canless Wafer Downlight has an innovative, slim design that installs quickly and easily into as little as 3in of plenum space allowing for it to fit into ceiling spaces where most traditional recessed housings do not. Wafers install directly into dry wall eliminating the need for recessed housings. Once installed, our Wafer provides an all-in-one design featuring switchable white color temperature and adjustable lumen output technology. This technology gives the ultimate in flexibility, providing you the equivalent of 15 static products in one.
