Omnilight settings?

I was editing the human lamp post; I had no problems in changing the light color, but there are a lot of other settings unknown to me.
To put it simple, my questions are: how does attenuation work? What's the difference between static Color and AmbColor? What is AmbIntensity about?


Light "Omni01" {
ObjectId 4,
Omnidirectional,
static AttenuationStart 100,
static AttenuationEnd 250,
Intensity 4 {
Bezier,
0: 14,
InTan 0,
OutTan 6.56369,
4867: 0,
InTan 1.89702,
OutTan -1.29933,
}
static Color { 1, 0.7, 0.6 },
static AmbIntensity 0,
static AmbColor { 1, 0.5, 0.5 },

Attenuation is the fade out at the edges; attenuation start is the beginning of the fade, attenuation end is the end. Not sure about the rest of it.
