NAME

       lampcolor - compute spectral radiance for diffuse emitter

SYNOPSIS

       lampcolor [ lamptable ]

DESCRIPTION

       Lampcolor  is  an  interactive program for computing the appropriate color for a diffuse emitter.  From the total lumen output and a simple
       description of the fixture geometry, the radiance for a diffuse fixture is calculated.  Since most light fixtures are not  really  diffuse,
       the preferred method is to use luminaire distribution data (see ies2rad(1)).

       A  table of lamp colors and depreciation factors is used to get the color for a specific lamp type.  If "white" is specified, the lamp will
       be uncolored.  This is probably preferable for scenes with only a single variety of lamp in order to produce color-balanced images.
