Dear friends,

 I began writing remarks at least to 

> 4.3 and 6.1.4 and
> 1.2 existing 'laws and legislation' and 
> 2.3.4 'latest consumer tests'

This is the first one:

4.3.1.3

 Light pollution definition given in the text is useless and evidently
wrong...

Cinzano's definition (explained in broad e.g. at
 http://savethenight.eu/What%20is.html, together with the necessary
measures to stop its rise; some printed reference should be supplied too
in the EuP document) is the only tenable. Reformulating it once more,
it is

   alteration of those levels of light, which would be present naturally

Of course, ``alteration'' means ``increase'' in this case.

Then it is easy to express such pollution quantitatively: in lumens, lux,
lm/m2, cd, cd/m2, or even in a more detailed way, caring about spectral
components (standardly in energy domain, stating the spectral sensitivity
curve).  Additionally, relative amount of change from natural levels
should be given, as per cents (or multiples, orders of magnitude...) of
natural levels.

Natural levels can be measured or computed. For landscape during clear
moonless astronomical nights, it's 1 mlx, for bedroom window 0.5 mlx at
most. Three to thirty times less on overcast nights (ten times less as a
rule). In such nights in urbanised areas, with a quite common 1 lx
artificial illuminance of the window, the pollution is 1/0.00005 or 20000.
On clear nights, it's 2000. On full moon ones, its ``just'' 10, or even 5
for several hours a month. (Some people use shading devices against
moonlight, as even that, in its limited timespan, is disturbing for them.)

There is even natural glare: Venus, Jupiter, even Moon sometimes. Any
distant luminaire can be compared to them and, e.g., the veiling
luminances computed (Moon is often glaring, but never when low in the sky,
so veiling luminances for pedestrians and drivers are not that bad).

Pollution of landscape is evident: any light points at negative angular
heights, apart from fireflies, glowworms, shining plancton and reflections
of stars. (Tolerable? pollution may be pilot lights, when obeying some
strict rules.)

Alteration of natural contrast is another phenomenon. In its extreme form,
it was found in the Giant Mts. Nat. Park in the Czech Republic in 2005.
Artificial illumination of a single ski slope wipes out the second largest
Czech Mountain: the luminance of its slope rises to the same values as the
luminance of the sky just above it... no outline of the huge mountain is
visible during these times.

Outdoor lighting at night = polluting the environment. As with some other
kinds of pollution, some aspects of it might be welcome by some, many or
almost all. Like the fossil-carbon-emissions-induced climate change for
winemakers in England...
