An optical housing is formed from a blank and a reflector mounting plate. The blank is scored to allow it to be folded into a box with a base and four walls. The box has a circular hole in the base and two wall tabs at the end of each of the four walls. The reflector mounting plate has wall tab slots that receive the wall tabs from the four walls and couples the two parts of the housing together. A set of reflectors is mounted to the reflector mounting plate in a predetermined reflector pattern. Another set of reflectors is mounted to the base of the box in a circular pattern. A third reflector fits into the circular hole in the base of the box and is mounted to the base. A light source is attached to the base of the box and extends vertically through a hole in the third reflector and partially beyond the first set of reflectors.
