1. A lighting system comprising:

  • a lamp housing including a lamp and a light-port, 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;

    a reflector to reflect the first portion of the collimated broad spectrum light that passes through the infrared absorbing filter;

    a short pass filter to pass a second portion of the collimated broad spectrum light, wherein the second portion of the collimated broad spectrum light comprises a subset of the first portion of the collimated broad spectrum light, and wherein the short pass filter filters out light of the first portion of the collimated broad spectrum light of wavelengths greater than 650 nm and less than 595 nm;

    an infrared blocking filter to pass the second portion of the collimated broad spectrum light after passing through the short pass filter, wherein the infrared blocking filter absorbs residual infrared light of the first portion of the collimated broad spectrum light; and

    a second lens to disperse the second portion of the collimated light that passed through the infrared blocking filter and the short pass filter.
