I'm sure someone somewhere knows this...it is probably some sort of guideline that the sign manufacturers must follow.
Maybe a DOT code of some sort.
How many lux is required to "reflect" a street sign?
I ask this, because I know of a 3/4 mile stretch of road near me, that many of my lights will illuminate the sign at the 3/4 mile mark.
So, I wonder, that's almost 4,000 feet. (1200 meters)
How many lux is at the 4,000' mark do you think?
