The instant this advanced Furtado 1 Light LED Spot Light throws out a powerful beam of white light. The light will remain on long as there is a presence in the beam but automatically switches off 20 seconds after movement ceases. The light runs on three AA batteries (not included) and its three super bright LEDs are so energy-efficient they provide approx. 50,000 hours of life. Ideal for dingy areas outside and inside your home and perfect for shedding light on new arrivals as they approach your front or back door after dark. Mounting bracket, double-sided tape, and fixing screws included, so there's no need to call an electrician - simply fix it yourself.
