This is a set of 3 battery-operated wireless LED puck lights, typically used for under-cabinet or closet lighting.
The lights feature adjustable brightness levels (bright, subdued) and include a 30-minute auto-off timer function on the remote.
Installation is done using included adhesive strips for a cordless, no-wiring setup.
Each light requires 3 AAA batteries, and the remote typically requires 2 AAA batteries, which are usually not included in the package
