Amazing what you can do with Google. Now we know why those two thirty-somethings are worth $18,000,000,000 EACH.

Okay-- don't be sarcastic--:grin: I was careless
This is the best I could find
ANSI/IES RP8/2000 American Standard Practice for Roadway Lighting ...
Seems to control the urban glow of lighting near observatories. The only site I found was in another language

What is RP- 8?
The Illuminating Engineering Society of North America (IESNA) developed Recommended Practice 8 (RP-8) as a guideline for
lighting design for Roadways. This document sets forth requirements and standards for Illuminance calculations, as well as
Roadway Luminance and Veiling Luminance calculations.
Recommended values for the various optimization criteria are based on RP-8. Certain limitations exist in RP-8, and are carried
through to Simply Roadway. For example, RP-8 applies only to straight sections of roadway. Subsequently, Simply Roadway
only models straight sections of roadway for this reason.
RP-8 also requires the length of the roadway to be at least ten times the mounting height of the luminaires, and at least five
times the pole spacing.
Simply Roadway will allow you to work with a road shorter than five times the luminaire mounting height, but please keep in
mind that in this case, your roadway lighting layout does not strictly comply with RP-8.

Also, www.DarkSky.org has a lot of information that helps you do the RP-8 calculations. This is brutal by longhand, but there are cheap software programs that do the RP-8 calcs.

OOps sorry-- I thought the link I posted was a bit vague and thought you were referring to that. My deepest apologies.
