see below some more info regarding full shielding and dimming, from a
September letter by Diego Bonata...  I'm sure even publishing the overview
of the European situation should be postponed, and a good status report
from the best practice in the six Italian regions with excellent
legislation (which is even not mentioned in the eup4light current drafts!)
should be included. These are not just vague possibilities for the future
of EU, this is reality already for several years! Thanks to legislation!

Of course, the overview should include the proper definition of LP, as
given on www.savethenight.eu and in scientific papers (independent on
lighting industry...). Did I mention the excellent paper from Frontiers in
Ecology? The book is to be bought, but the paper is online too, at
www.urbanwildlands.org (this does not contain the proper definition, but
it is written by biologists, not by physicists, so it can be forgiven, and
it points out correctly that there are grave concerns with such aspects of
lighting, which are often neglected...).

(It occurred to me, that my estimate of proportion of MV lamps in Czechia
was perhaps still too high, they almost don't exist in towns any more.
Second, the electricity consumption in mid nineties was the lowest in
recent history, nowadays it is probably ten per cent more, with wattage
per fixture falling down, so 0.11 lights per capita is the lowest
estimate. And as regards dimming: the savings are at least 30 per cent, as
I spoke with some people from that industry and with the manager of Brno
streetlighting: just adding such dimmers to the switch box of old
installation...)

Dear Bob,
...

- My departement (1.5 million people) last year spent 180.000 Euro to
promote the conversion from mercury vapor to high pressure sodium source
and with FULLY shielded lighting systems (0 cd/klm over 90 °). We changed
over 5000 luminaires with an energy saving (each year) of about 115.000
Euro. Certified.

- Only in the Bergamo area (my town) we installed everywere in pubblic
lighting flux reducers 3 year ago and we save (certified) each year
160.000 Euro of energy (but also in maintenance we have a lot of saving).
This situation is common for a lot of Italian cities, first of all were
there are a good LP law (8 best regional low).

- In Lombardy over 10% of town (more than 180) have flux reducers with
high level of energy saving (over 26%, certified).

- Also in Frosinone, which started first years ago, we have a consistent
energy saving ... Mario can confirm to you.

- We calculate that in Lombardy, Emilia-Romagna and Marche regions in 3
year we substituted over 50.000 luminaire with fully shield luminaire HPS.

I have hundreds of similar examples.

We candidate for your award 3 towns, according to the CieloBuio technical
parameters that sincerely ... in the 3 last year I have the impression
that is different to IDA ones. The 3 towns respect all the 5 FONDAMENTAL
elements of our Italians laws:

1- luminaire with fully shield (0.49 cd/klm over 90 °)

2- level of luminance and illuminance not more than the minimun defined by
European technical norms (UNI10439, DIN5044, EN 13201, etc..)

3- Efficient lamps (over 89 lm/W)

4- Plants with high level optimization (for example for street, ratio
between distance of two pole and pole height over 3.7).

5- (and last fundamental point, but only after the other 4 point).
Lighting flux reducer systems.


If you want some technical information you can translate with some web
source this 5 elements detailed in the first page of www.cielobuio.org
(there is also a english section) and if you want to make lighting plants
with this 5 Fondamental Elements consult http://www.savethesky.eu that is
a independent lighting software.

... This year San Benedetto won (second place) ..... but the results are
not comparable with Fara Gera d'Adda (65% of energy saving!!!!!)...... and
the same respect, as San Benedetto Po, of the 5 fondamental and technical
elements.

....

Best regards Diego Bonata
