Abstract

An apparatus, system and method for aiming solid state lighting modules that are mounted in a lighting fixture. The apparatus comprises an aiming station space from a projection surface. At least one reference laser projects from at or near the aiming station to the projection surface. The lighting module is preliminary attached to a supporting structure or rail that is mounted at the aiming station. An aiming laser is temporarily attached to the housing. The module is manually adjusted on its mounting rail to align its aiming laser with a reference position on the projection surface. The module is then locked in to position.
