A wall-mountable strobe unit emits radiant energy over a one hundred eighty degree arc in a horizontal plane and over a ninety degree arc in a vertical plane when so mounted. The unit includes a reflector and an elongated light source. The elongated light source is symmetrically positioned on the reflector with one end thereof carried on the reflector with the light source extending in the horizontal plane when so mounted. The reflector includes first and second planar elements symmetrically located with respect to the light source. The planar elements are joined by symmetrically located curved elements formed of partial parabolic surfaces. The partial parabolic surfaces extend from the planar elements first rising a predetermined amount from the planar elements and then falling back toward the planar elements. Two additional partial parabolic surfaces are positioned adjacent to the planar surfaces, symmetrically located with respect to the light source and displaced from the parabolic surfaces with the planar surfaces therebetween.
