Spotlights in Photometric Workflow
In photometric workflow, the hotspot intensity falls to 50 percent. The hotspot
for standard lighting is at 100 percent. At its falloff angle, intensity of the
spotlight falls to zero. Additional properties become available for a point light
when LIGHTINGUNITS is set to 1 (American units) or 2 (International SI units)
for photometric lighting:
Lamp Intensity. Specifies the inherent brightness of the light. Specifies
the intensity, flux, or illuminance of the lamp.
Resulting Intensity. Gives the final brightness of the light. (Product of
lamp intensity and intensity factor. Read-only.)
Lamp Color. Specifies the inherent color of the light in Kelvin temperature
or standard.
Resulting Color. Gives the final color of the light. This is determined
by a combination of the lamp color and the filter color. (Product of lamp
color and filter color. Read-only.)
