I don't even know how lighting works in all possible situations.

My main point was that the values you specify in your code get divided by 255.
Then all the internal calculations, whatever they are, get done.
The resulting value gets multiplied by 255 to determine pixel color.

Here's another example to emphasize that there really is no restriction on light values.

Open in online IDE

Graphics3D 640,480,32,1

AmbientLight 0,0,0

camera=CreateCamera()

cube=CreateCube()  :  PositionEntity cube,0,0,5

blue1# =  300
blue2# = -200

light1 = CreateLight() : LightColor light1, 0, 0, blue1
light2 = CreateLight() : LightColor light2, 0, 0, blue2

While Not KeyDown( 1 )

	If KeyDown( 2 ) Then blue1 = blue1 - 1
	If KeyDown( 3 ) Then blue1 = blue1 + 1
	
	If KeyDown( 4 ) Then blue2 = blue2 - 1
	If KeyDown( 5 ) Then blue2 = blue2 + 1
	
	Delay 40
	
	LightColor light1, 0,0, blue1	
	LightColor light2, 0,0, blue2	
	
	RenderWorld
	
	Text 0,0, "1,2 changes light1.    3,4 changes light2."

	Text 50,50, "light1 blue: " + RSet(blue1, 7)
	Text 50,70, "light2 blue: " + RSet(blue2, 7)
	
	Text 50, 100, "blue1+blue2 = " + (blue1+blue2)
	Text 50, 120, "screen blue = " + ( ReadPixel(320,240) And $FF )
	
	Flip
