Replying to Spy Soldier Lens

Does anyone know if there is a spy lens chart online somewhere? I've been checking the spy optic website now for the past 15 minutes and can't find one.

Basically I'm looking for a chart to tell me what lens is designed for what lighting.

I have a bronze lens on mine right now, and I'd like something lighter at night. Perhaps a clear lens, or maybe Persimmon. But what other low light lens are available?

And also does anyone have any lens for sale? In new or good condition?
