1 	ID		Integer 	
2 	iRefID_Map	Integer 	
3 	position	Float[3]
6 	falloffStart 	Float		If you are within the inner radius there shouldn't be any interpolation with other lights.
7 	falloffEnd 	Float		If you are outside the inner radius but inside the outer radius then this light can be interpolated with other lights.
8 	Sky & Fog	Integer 	These entries are all IDs in LightParams.dbc. (and in LightIntBand.dbc, LightFloatBand.dbc?)
