When working with photometric lights (see the
ies property) or physically-based rendering (see
physically), you can leave the
color property at its default white color and use the
temperature to control the light using realistic parameters. When working with physically-based materials, this value the luminous flux of the light source. The default value is
When not using physically-based rendering, this value (divided by 1000) serves as a multiplier for the the
color property. The default value of of
1000 leaves the light color unmodulated; you can use higher values, for example, to brighten a light whose color is already the maximum red value.
You can animate changes to this property’s value. See Animating SceneKit Content.
