content: A cylindrical metal shell with an arched opening on one side that as a perforated metal shield partially covering a photoelectric cell. Plastic base. Donor’s card reads: “Photoelectric lighting control made by Fisher-Pierce Company, 170 Pearl Street, South Braintree 85, Mass. This device contains a light sensitive device and a power switch. Used principally for the control of outdoor lighting, eliminating the need for special street light circuits. With this device placed on top of a pole or light fixture, with the window pointing to the north, a street light may be connected to the nearest available power line and will be turned on at night and off in the morning by this device. Turns the light in wen the natural light falls to 1.5 footcandles and off wen it reached 5 footcandles of natural light. Operates from 105/130 volt AC circuits and will handle a 1000 watt load for a guaranteed life of 2 years. First used in West Chester, Pa., in 1959.”
