Optronics IL21CS Interior Dome Light with Switch, White, Surface Mount

The Optronics IL21CS is a surface-mount interior dome light built for boats, RVs, and other vehicles that need reliable, compact cabin illumination with onboard control. It features an integrated on/off toggle switch right at the fixture, so occupants can turn the light on or off without a separate wall switch or panel connection. The housing pairs a durable steel base plate with a polycarbonate lens, giving the fixture resistance to impact and the vibration common in marine and mobile applications, while keeping the unit lightweight at 0.34 pounds. Both the lens and the bulb are replaceable, which means the fixture does not need to be discarded and replaced as a whole unit if the bulb burns out or the lens becomes scratched or discolored over time. The IL21CS is hardwired, supplied with both a lead wire and a ground wire, and runs on a 12.8VDC electrical system drawing 2.4A. Its compact footprint of 4.563 inches by 2.5 inches by 1.75 inches allows it to fit into tight overhead or cabin mounting locations, and it mounts on a 3/5 inch center. Finished in white, the light blends easily into most interior color schemes. Optronics backs the IL21CS with a three year warranty.
