The Lotus LED Lights Round Slim LED Recessed Trim is designed exclusively for showers and outdoor settings where water exposure may occur. It has an airtight, 1” thick body that allows for versatile installation and lighting setups that are not overly dependent upon the structural layout of a building. It comes with an isolated external driver (inside an included wire box), so that you can position light and driver separately when needed. One driver for every fixture is required.
