I will be there and I want to have some good ideas on hand to give to them
to
save money...

Good job, Starlord. I know you haven't much time to get ready, but if you
could have a look on our site http://www.cielobuio.org you'll find a nice
leaflet (http://www.vialattea.net/cielobuio/s...pieghevole.zip)
summarizing the directives of Lombardy Regional Law against light pollution
(which, BTW, quickly became the Czech Republic National Law agains light
pollution) showing various kind of allowed and not-allowed fixtures.
Sometimes a picture is worth a thousand words, and you'll find also a
gallery of "monsters" ("I mostri del cielo") showing i.e. how a parking lot
can become a nigthmare.
As far as bulbs are concerned, try to avoid halogen lamps: they will
probably say that this white light will increase the beauty of leaves green
color (and you can reply that they are meaning the Milky Way is a bad
sight...) but the same result can be achieved by compact fluorescent bulbs
with less energy requirements and less power.
There is also an English section on the site, even if not as complete as the
Italian one.

Dark (and clean) skies,
