Description from Lumens

The De-light Doorbell Button by Spore is unique for its industrial design aesthetic and its use of modern materials. This doorbell features a soft polymer resin button and anodized aluminum. It has incorporated LED illumination, a light source that consumes very low power and offers a much longer service life than any other light source. The easy-to-install De-Light Doorbell Button works with most existing and new doorbell systems and surface mounts without any visible screws.
