In the disclosed outdoor lighting control, angular reflectors (52) direct vertical light passing through a translucent dome (38) onto a vertically oriented photocell (24) and a rigid vertically-adjustable sheet (54) between the photocell and the reflectors regulates the operating point of the photocell. The backs of the reflectors, and a socket (14) projecting vertically from a base (12) under the dome, shield the vertical photocell from horizontal light. |
