■ Hotspot cone angle. Defines the brightest part of a light beam. Also known
as the beam angle.
■ Falloff cone angle. Defines the full cone of light. Also known as the field
angle.
■ Rapid decay area. Consists of the region between the hotspot and falloff
angles.
The greater the difference between the hotspot and falloff angles, the softer
the edge of the light beam. If the hotspot and falloff angles are near equal,
the edge of the light beam is sharp. Both values can range from 0 to 160
degrees. You can adjust these values directly with the Hotspot and Falloff
grips.
Photometric Properties
Photometric lighting offers additional properties that make the lighting
different than standard lighting. The following properties are under the
Photometric properties panel:
■ 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.)
