Abstract

A wall light system including a single piece wall mount extrusion having a vertical rear mounting surface and a horizontally extending light shield. The interior of the vertical rear mounting surface has first and second projections extending therefrom defining a first slot, while the interior of the light shield has a downwardly extending vertical projection and a horizontal projection formed thereon, which together define a second slot. A lampholder has lower and upper tongues positioned to snap fit into the first and second slots, respectively, and mounts a circuit board which carries one or more LEDs.
