There isn't a way to extract this information with a Mathematica 
command, but I can give you the effective value as of version 6 and later.

Lighting->Automatic for Graphics3D is

Lighting->{
{"Ambient",RGBColor[{0.312,0.188,0.4}]},
{"Directional",RGBColor[{0.8,0.,0.}],ImageScaled[{2,0,2}]},
{"Directional",RGBColor[{0.,0.8,0.}],ImageScaled[{2,2,2}]},
{"Directional",RGBColor[{0.,0.,0.8}],ImageScaled[{0,2,2}]}
}

Lighting->"Neutral" for Graphics3D is

Lighting->{
{"Ambient",RGBColor[{.35,.35,.35}]},
{"Directional",RGBColor[{.37,.37,.37}],ImageScaled[{2,0,2}]},
{"Directional",RGBColor[{.37,.37,.37}],ImageScaled[{2,2,2}]},
{"Directional",RGBColor[{.37,.37,.37}],ImageScaled[{0,2,2}]}
}
