The Lamplighter is a palm-sized wireless device that not only will flash a lamp with a distinct pattern when it receives a signal from a transmitter, but will also light a button next to each symbol to let you know what you're being alerted to.
The large box part is actually the transformer that has a cord that plugs into the ac outlet on the wall. You plug the lamp power cord into this part. The round signaler is attached to transformer by a cord and can sit on a table or nightstand. You can then see which icon lights up when the lamp is flashing.
Ranges up to 100 feet and works with all 318Mhz Silent Call transmitters. One year warranty. This product has been discontinued and is available on a while supplies last basis. Please call for update.
