1. A lighting fixture for precision lighting comprising:

  • a. a housing comprising;

    i. an interior space;

    ii. an opening;

    iii. a light transmissive material over the opening to at least substantially seal the interior space;

    b. internal light control in the interior space of the housing comprising;

    i. an array of densely packed LED light sources mounted on an LED mounting substrate having a substantially planar surface;

    ii. an optic on each LED light source to produce a preliminary light output beam pattern from individual light source output beam patterns wherein the optic comprises;

    1. an emitting face formed from a substantially thin sheet of optical quality silicone-based material; and

    2. a holder to removably clamp and closely position the sheet over a subset of the LED light sources;

    iii. an internal visor at or near at least some of the LED light sources to selectively redirect a portion of the preliminary light output beam patterns;

    iv. so that a composite light output is directed out of the opening and light transmissive material of the housing from the plurality of individual redirected LED light sources outputs;

    c. external light control on the housing outside the interior space comprising;

    i. an external visor at or near the opening having;

    1. at least a first surface that is extendable at least partially into the composite light output from the housing and has selectable;

    a. reflectivity to control incident light from the composite light output;

    b. pivotability relative to the housing to selectively adjust cutoff of the composite light output from the housing;

    2. at least a second surface outside the composite light output from the housing; and

    d. an adjustable armature to selectively aim the housing in space so to collectively provide precision lighting.
