A billboard includes a support structure and a display surface mounted on the support structure. A first lighting assembly is mounted on the support structure and includes LEDs directed toward the display surface so that the first lighting assembly can illuminate a first portion of the display surface. A second lighting assembly is also mounted on the support structure and also includes LEDs directed toward the display surface so that the second lighting assembly can illuminate a second portion of the display surface. The first portion and the second portion constitute the entire display surface. The entire display surface can be uniformly illuminated using only the first lighting assembly and the second lighting assembly such that the light intensity across the display surface is provided with a uniformity that achieves a 3:1 ratio of average illumination to minimum illumination.
