Abstract: A system and method for streetlight control is provided. A lamp sensor inside a reflector of the streetlight is utilized to detect the output of a lamp of the streetlight. During daytime periods when the lamp is OFF, the lamp sensor is utilized to act as a day/night sensor by detecting ambient light near the lamp. When the ambient light level falls below a sufficient level indicative that night is approaching the lamp is turned ON and the lamp sensor utilized to detect the lamp output of the streetlight.
