what worked for me to get a developer to include light rules in his deed
restrictions was 1) keep it simple
2) show these examples from IDA

http://www.darksky.org/~ida/infoshts/is122.html

How come no one in the lighting industy seems to be aware of this
stuff?

They are (or at least some are) but their PHBs only care about selling
more and more lamps. I don't always agree with lighting policy, but the
lighting engineers are usually aware of some of the issues. The general
public is much more of a problem since they equate glare with safety.

In the UK one leading DIY chain actually has environmentally friendly
car park lights outside and a huge stack of discounted parabolic 500W
quartz halogen rottweiler lights stacked for sale to the punters at
every checkout.

Amazingly the better designed lower power outdoor lamps are much more
expensive than the nasty parabolic tin cans they sell in such bulk.
