Abstract
A method for quickly, efficiently and accurately aiming a flood light at a preselected location which involves directing or redirecting the collimated radiative output of a low power laser source at a preselected location. The laser output may be aimed at a mirror on the flood light face and reflected directly back to the preselected location or the laser can be temporarily mounted to the flood light and the laser output directed parallel to the flood light beam axis at said preselected location.
