**Light Type:** _Light object type. "Point", "Area", or "Spot"._

**Coordinates:** _Coordinates of the light object relative to the bounding sphere of the target objects._

**Radius:** _Radius of the polar coordinate, as a factor of the bounding sphere. For example, if the bounding sphere has a radius of 2 meters and the radius in this input is also set to 2, the light would be placed 4 meters from the origin._

**Theta/Phi:** _Defines the azimuth angle and polar angle, respectively, expressed in degrees. Theta (azimuth) is limited to a range of \[0, 360] and Phi (polar) is limited to a range of \[0, 180]._\
\
&#xNAN;**\[r=1, θ=0, φ=0]:** Point at the upper pole of the sphere.\
&#xNAN;**\[r=1, θ=0, φ=90]:** Point at the equator, aligned to the +X world axis.\
&#xNAN;**\[r=1, θ=90, φ=45]:** Point aligned to the -Y world axis, halfway between the upper pole and equator.\
\
**Size:** _"Size" of the light object. For Point and Spot lights, this is the radius of the light. For an Area light, this is the width/height of the light._

**Power:** _Radiant power of the light in watts._\
\
**Color Temp:** _Color temperature of the light in degrees Kelvin (more information on blackbody radiation may be found_ [_here_](https://en.wikipedia.org/wiki/Black-body_radiation)_)._

**Chance:** _Chance for this light to be created._
