Class Lamp

The Lamp Data object

This object gives access to Lamp-specific data in Blender.

Warning: Most member variables assume values in some [Min, Max] interval. When trying to set them, the given parameter will be clamped to lie in that range: if val < Min, then val = Min, if val > Max, then val = Max.
