When a model is influenced by more light than allowed, or when it reach the limits of the light (attenuationEnd), the light can be darkened according to some threshold. The resultLightColor begin to fade when distModelToLight== attEnd- threshold*(attEnd-attBegin). when distModelToLight== 0, resultLightColor==Black. By default, this value is 0.1f. Setting higher values will smooth transition but will generally darken the global effects of lights.
