A lighting apparatus having a pivotable light cartridge for positioning and directing the light output of a plurality of light sources, the light cartridge including an elongated base oriented along the longitudinal axis, a pivot at the opposed first and second ends of the light cartridge along the longitudinal axis, a plurality of light sources, and an longitudinal wall extending from the lateral edge of the base, the wall including a plurality of spaced-apart, radially-extending ribs, each having a distal edge. A rotatable worm gear having a helical thread is positioned in mechanical engagement with a portion of the distal edges of the plurality of ribs, so that rotation of the worm gear with a hand tool effects pivoting of the light cartridge along the longitudinal axis. |
