boxlight falloff

[Armored Cow]

Another question regarding box lights: Whenever I read a tut on that, the author (in this case Luis) writes about placing a super 'faint' box light..

Whenever I try that, I end up with a lighting in my levels as if I had a mercury arc lamp instead of a lantern (meaning very VERY bright). Is there an Alpha setting that corresponds to this? The Alpha in color doesn't do anything

Alpha controls the specular light. You simply lower all of the values to make darker colors. Darker colors = less bright.
