When defining a spotlight, you can specify beam, field, and tilt angles.
- Beam angle: The angle at which light intensity reaches 50% of the peak intensity. Enter a value between 0 and 160 degrees. To make a spot that is small and bright, enter a smaller value.
- Field angle: The angle at which light intensity reaches 10% of the peak intensity. Enter a value between 0 and 160 degrees. To limit the spread of the spotlight, enter a smaller value.
- Tilt angle: The angle that the spotlight is tilted from its origin. You can adjust the tilt angle of a spotlight to aim its light in the desired direction.
