--repetition Count128 128-byte Section:
	DWORD Type	// type of light: point, spot etc
	FLOAT F1	// x position in tiles (+ moves to object's left)
	FLOAT F2	// y position in metres (+ moves up)
	FLOAT F3	// z position in tiles (+ moves in front of object)
	FLOAT F4	// red 0-1
	FLOAT F5	// green 0-1
	FLOAT F6	// blue 0-1
	--see table below for usage of the following
	FLOAT F7	// intensity
	FLOAT F8	// (0-1) affects rotation about y
	FLOAT F9	// (0-1) affects rotation about z
	FLOAT F10	// (0-1) affects rotation about x
	FLOAT F11	// affects cone angle.  Probably bare degrees
	FLOAT F12
	FLOAT F13
	FLOAT F14	// width (dimension)
	FLOAT F15	// height (dimension) these affect area of the light source (or amount of daylight let in by window) and thus amount of light
	FLOAT[] F16-F31	// more light parameters

--repetition Count56 56-byte Section:
	DWORD 
	FLOAT[] F1-F13	// light parameters, not all used at once

Known Types

128-byte Sections

Actual usage of the light parameters varies by type of light, as follows:

Notes

Intensity affects decay (how far the light reaches) rather than apparent brightness at source. Use the colour (rgb) settings to make softer lighting.
