Memorandum from Mr A N Hasluem
I have been an amateur astronomer for 30 years.
During that time, light pollution has steadily worsened in this
country. I am dedicated to my hobby, so much so, that in the last
20 years I and my family have moved from SE London to Kent to
Norfolk to escape the exponential growth in light pollution.
IMPACT OF
LIGHT POLLUTION
ON UK ASTRONOMY
I am of the opinion that UK visual Astronomy
has been killed by light pollution. The professional telescopes
left years ago, and a lot of amateur astronomers have either given
up, or moved abroad. As for anyone just looking up and seeing
the Milky Way, unless one lives on a Scottish Isle, forget it.
In the last few years, the effect of light pollution
of so-called "security" lighting, both domestic and
industrial, combined with poorly designed sports lighting has
caused the night sky to be obliterated for most people. I have
spent hundreds of hours of my time persuading people to adjust
or remove their bad lighting so as not to negate my investment
in thousands of pounds of astronomical/scientific equipment. I've
never had a refusal, but the scale of what I'm up against is now
overwhelming. It only takes one cheap B&Q security light to
light up the sky and the surrounding area to resemble Colditz,
and to render my hobby useless. Not to mention trying to sleep
when one's bedroom is lit up from a source over which one has
no legal control.
This not only affects Astronomers and other
humans, as where I live in rural Norfolk, I have often heard birds
calling in the middle of the night in the vicinity of blindingly
bright industrial estates and sports pitches.
PLANNING GUIDELINES
I have had experience of this. Current guidelines
are just thatguidelines. When my village street lighting
(six fittings total) was to be replaced due to old age, I made
my case to the Parish Council, backed up by information on planning
guidelines and good lighting practice, so that the new lights
would be efficient, and would not cause light pollution. My reasoned
arguments were totally ignored by the Council, the local Electricity
Co, and the Highways authority. We ended up with poorly designed
fittings, that were only installed, as they were cheap. When I
pointed out that my house was more brightly lit by them than the
road, I was told that to shield my house was not possible without
messing up the road illumination. In my reply to this I stated
that the conclusion to the correspondence was that the design
of the lights was seriously flawed. No reply.
As for the enforcement of planning guidelines,
I believe that we are seeing definite progress with respect to
street lighting. Full cut-off fittings are much more in evidence
in new installations. However, replacement of existing worn out
fittings often appear to be just that, not improvement by substituting
modern shielded units.
No amount of planning guidelines can protect
against the subsequent additions of ad-hoc floodlights
and "security" lights. We need light pollution law.
LEGALLY ENFORCEABLE
REGULATORY CONTROLS
AND THE
DESIGN OF
LIGHTING
I wish to treat these two subjects as one. It
is no use having legal controls if the hardware does not exist
to make compliance practicable. I suggest that a simple legal
requirement should be met where an owner of light fittings should
be responsible for not allowing any of the light generated to
illuminate any land beyond his boundary, including not allowing
any light to escape above the horizontal.
That is all that is needed, along with well-designed
light fittings to allow this constraint to be met.
We already have laws on the books for noise
pollution. It is very difficult to stop sound spreading beyond
a defined boundary. By contrast, preventing light pollution is
simple.
I would also suggest that the committee looks
into the feasibility of switching off unnecessary street lighting
at night, and decommissioning street lighting where appropriate.
We are subject to a barrage of COIs telling us to save energy.
The amount of energy and light wasted by street lighting that
is not needed is colossal, and far outweighs any savings that
can be made by individuals in other ways.
