Direct Known Subclasses:

GLSLAreaLight, GLSLDirectionalLight, GLSLPointLight, GLSLSkyReflectionLight, GLSLSpotLight

public abstract class GLSLLightShader
extends GLSLManagedShader

Convention: If ambient is set to less than -1.0 the pixel should not be lit, only its diffuse color will be used to render it.
