Memorandum from Mr Kenneth R Whayman
May I say at the outset that this inquiry is
good news and is, in my humble opinion, long overdue. It seems
to me that the time for educating the public and in some cases,
local authorities, about badly designed and badly sited lighting
is over and what is now needed is enforceable legislation.
I am 61 years old and started astronomy in 1951
when, on my tenth birthday, Dad gave me his Army binoculars; through
the years I have owned a variety of telescopes and now have a
16 inch reflector; through the years I have watched with dismay
as the glory of the night sky has gradually been diminished by
ever-increasing and ever-encroaching light pollution which I personally
find both disheartening and demoralising.
I moved to my present home in 1976 and back
then I could walk out into my garden, look up and easily see the
spiral arm of the Milky Way; now I consider myself lucky if I
glimpse it half a dozen times a year on an exceptionally clear
night.
This is due to one thing: light pollution from
the aforementioned badly designed and badly sited street lighting
and to a lesser extent house security lighting commonly known
among both amateur and professional astronomers as Rottweilers
or the even more apt name, photon torpedoes.
I submit that the average householder with an
average size garden like my own of 50 feet by 25 feet (just to
take one example), does not need a 500 watt security light mounted
under his guttering in the almost horizontal position spilling
its glaring white light into half a dozen or more other gardens
and into the windows of other houses and up into the night sky.
I have three such lights opposite my house and
garden and, as sometimes happens, all three are on at the same
time; the light from these dreadful lights would do justice to
a football stadium at a night game.
What is needed here are enforceable laws defining
the maximum height, angle and wattage; I understand that such
laws exist in the United States and are enforced.
I have two bulkhead lights on my house mounted
10 feet up; they are shielded and contain 60 watt energy saver
bulbs (you may be aware that a 60 watt energy saver bulb uses
only 10 watts of electricity). Both lights are mounted over a
vulnerable garage door and an equally vulnerable rear window overlooking
the garden and, being shielded the light goes only in one direction:
down.
I have understanding neighbours and they have
adjusted the timers on their lights to the minimum "on"
time and two of them have angled their lights down so that none
of the light spills up into the night sky. The third neighbour
is not so accommodating and his light shines everywhere being,
as it is, about 25 feet high.
I come now to street lighting and it has to
be said that there are many good street lights in my area along
the main traffic routes and these are nearly all of the Full Cut-Off
type (FCOs); there is though, still room for improvement and some
side-street lighting leaves much to be desired.
My own road boasts a poor design whereby the
bulb in the light is not shielded and a lot of light goes out
to the side and upwards. I count myself extremely lucky that not
one of these lights actually spills its awful orange glow into
my garden and, by extension, down my telescope tube and into my
eyes. Nevertheless, the light is still there adding to the general
orange sky-glow, which spoils our view of the night sky.
My local railway station has superb FCO lighting
along the two platforms but here we have a case of overkill: there
are far too many of them and if every other light was to be removed
there would still be plenty of light for security purposes; however,
the effect of these marvellous lights has been entirely negated
by the dreaded globe lights in the adjacent station car parks.
There are a dozen of these lights and at night
the light from these horrible designs being thrown up into the
night sky has to be seen to be believed.
My local pedestrian Shopping Mall also has these
globe lights, dozens of them throwing their awful orange glow
up.
Near that lot, a local school has opened half
a dozen seven-a-side Football pitches and these really are very
badly lit by badly sited lighting.
These, too, have totally negated the globe lights
at a nearby Supermarket car park where such lights have been fitted
with a black dome inside of which is a silver reflector (rather
like a car headlamp); the bulb is at the top part of the globe
so naturally all its light goes down.
If you want to see an example of truly awful
and wasteful lighting in London, just pop long to Victoria Street
and look at the Army and Navy store. Here is just one example
of a buildingand a very ugly one to bootthat could
so easily be illuminated from above as could countless others
in towns and cities nation-wide.
This brings me very neatly to a point that nearly
every astronomer I've met, both amateur and professional seems
to know about, but certain people who should know, don't: if you
have a totally shielded light throwing all its light down, it
would be possible to fit such a light with a much lower wattage
bulb thereby reducing bills literally overnight and saving on
Earth's precious, finite resources at the same time.
I understand that you are particularly interested
in the following questions:
1. What has been the impact of light
pollution on UK astronomy?
In my opinion it has become severe enough to
warrant action by enforceable legislation.
2. Are Current planning guidelines strong
enough to protect against light pollution?
It seems not. Enough of guidelines; surely guidelines
are just thatguidesthey let anyone, anywhere erect
any kind of light.
3. Are planning guidelines being applied
and enforced effectively?
In some areas they appear to be but in other
areas lighting seems to be erected willy-nilly.
4. Is light measurable in such a way
as to make legally enforceable regulatory controls feasible?
I'm no scientist but I tend to think that given
what could once be seen in the night sky, with or without optical
aid, but cannot now be seen, regulatory controls are not only
feasible but desirable.
5. Are further controls on the designs
of lighting necessary?
Yes. Just one example I cite again the dreaded
house security light: these should be designed so that they cannot
be angled above the horizontal and cannot be left switched on
permanently. Globe lights should be outlawed forthwith and existing
types replaced or retro-fitted with a domed cap. All street lighting
should be of the Full Cut-Off type. If older types cannot be replaced
they too should be retro-fitted with some type of metal or Upvc
side shielding.
To me and no doubt thousands nation-wide (perhaps
millions world-wide) the night sky is as much a part of our natural
surroundings and as precious as wildlife and the countryside and
you won't need the likes of me to remind you of the enforceable
legislation in place to protect those.
Many, including myself, have written to our
local authorities and what was then Railtrack about wasteful and
badly sited and designed lighting. Some, precious few, received
favourable replies and action was taken resulting in improved
shielded lighting and an improvement in the visibility of the
night sky. Most, myself included, received no reply at all; still
others received pages of waffle about the holistic value of certain
designs with no mention at all of light spillage and wastage;
little wonder then, that so many of us feel we are banging our
collective heads against a brick wall and we look to you to do
somethingtake action, get laws passed before the glory
of the night sky disappears in a sea of sickly orange sodium light:
enough is enough.
I'm as security conscious as the next person
and don't want to be in total darkness at night and indeed, our
aim is not to switch off night lighting but to control it even
more effectively than it is now.
I sometimes listen to weather reports for aviators
and I am filled with dismay when I hear that the cloud base is
2,000 feet because I feel that if the glow of street and other
lighting is visible up to that height then there is something
seriously wrong with such lighting and this needs to be addressed
as soon as possible.
The very fact that there is a meeting convened
to address this issue and that I and many others will be writing
to you about it indicates that something needs to be and must
be done.
I understand that Mr Bob Mizon of the Campaign
for Dark Skies will be presenting evidence: listen to this manwhat
he doesn't know about bad and wasteful lighting isn't worth knowing
anyway.
