| In "LCS" mode only the currently selected fixture is active. The fixture is placed in the center of the sphere. Light from the fixture is projected onto the face of the sphere. This mode displays the light distribution based on a proposed luminaire classification system, hence LCS. See IESNA TM-15-06 Luminaire Classification System for Outdoor Luminaires for more details. The light intensity is grouped into several zones, each highlighted with a color as shown below:
Displayed at the bottom right of the output window is the fixture efficiency for each zone, calculated using the IES Zonal method of computing luminous flux from intensity data. If the "WL" checkbox is selected the light intensity is displayed as white light. If the "ID" checkbox is selected the light output is displayed as a 3d envelope based on the intensity and direction of the light as shown below:
