Applications

Photoelectric lighting controls of this type are used to automate outdoor area lighting — street lights, parking lot fixtures, security lights, and building exterior lighting — switching them on automatically at dusk and off at dawn without manual intervention. The Fisher Pierce / Sigma Instruments line was widely used in commercial, municipal, and industrial outdoor lighting installations throughout the United States. The 200–300VAC voltage range makes this unit compatible with higher-voltage outdoor lighting circuits common in commercial and light industrial settings. These controls mount directly into the standard twist-lock photocell receptacle found on most American outdoor lighting fixtures made from the 1960s onward.
