1. A lighting system comprising:

  • a lamp housing including a wall, a lamp, and a light-port, wherein the light-port is located within the wall, and wherein broad spectrum light from the lamp exits the lamp housing through the light-port;

    a first lens to collimate the broad spectrum light that exits the lamp housing through the light-port;

    an infrared absorbing filter to pass a first portion of the collimated broad spectrum light and absorb infrared light of the broad spectrum light that passes through the light-port and that is collimated by the first lens, wherein the first portion of the collimated broad spectrum light comprises a second portion of the collimated broad spectrum light;

    an optical filter to pass the second portion of the collimated broad spectrum light after the first portion of the collimated broad spectrum light reaches the optical filter;

    a second lens to disperse the second portion of the collimated light that passed through the optical filter, wherein a position of the second lens is adjustable in at least one of a direction parallel to the wall and a direction perpendicular to the wall;

    a shelf including a shelf top perpendicular to the wall; and

    a lens slider removably attached to the shelf top, wherein the second lens is removably attached to the lens slider, wherein the lens slider includes a first hole for passing the dispersed second portion of the collimated light that passed through the second lens, wherein the shelf includes a second hole for passing the dispersed second portion of the collimated light that passed through the second lens, and wherein at least a portion of the first hole is above or below at least a portion of the second hole.
