Types of Lights
From ZBrush Info
In the Type subpalette you can choose the type for a selected light.
Sun: Infinitely far away, the Sun light illuminates the entire scene with parallel rays. The intensity of the light does not diminish with distance, so all objects in the scene receive an equal amount of light.
Point: The point light has a position in the scene and its intensity falls off with distance, so objects further away from the light are illuminated less. Omnidirectional, it casts rays in all directions.
Spot: Illuminates in the same manner as the point light, except that it has direction. Place the light as described previously to control direction.
Glow: Illuminates all objects within the radius of the light equally, regardless of the direction they are facing.

Radial: Usual light behavior is to light the areas facing the light brighter than areas facing away from the light. The Radial light illuminates the areas facing away from the light. This makes it a perfect “fill” light when placed at the same position as the main light.
