Light Pollution

This is a composite image produced by joining three original photographs together. The images were taken with a 50mm lens at f1.7 and 10 second exposure, on Kodak Gold 2 film speed 400 ASA.

*Our society aims to preserve and restore the beauty of the night sky by campaigning against excessive, inefficient and irresponsible lighting that shines where it is not wanted nor needed, even in the towns. The glow above Cardiff, Newport and Swansea etc. pollutes the skies elsewhere as well as denying the next generation of town dwellers a chance of experiencing the wonder of the skies.

Unfortunately, light pollution is getting worse, even in these times of uncertain energy supplies. The dark skies of rural Wales are not being cherished and safeguarded as they should be by those who should know better.

Floodlighting has become a status item helped along by public bodies such as the Welsh Assembly (Heads of the Valleys Spectacular Trail of Light), Cadw (floodlighting of public buildings), churches (the Millennium project) and councils (up-lighting of bridges in Newport). Like a virus, it spreads by the "me too" process.

The quality of such lighting is often disappointing, although designed by "experts". Buildings are lit up where and when there is nobody about to see.

If you have a comment on lighting in your area, contact your local representative and make your views known. It all counts.*

A seminar was held at the Brecon National Park Visitor Centre on 14 October 2015.
The purpose of the seminar was to discuss the possibility of Wales becoming the first Dark Sky Nation and debate the opportunities and potential barriers to this.
The seminar was very productive with a united positive attitude towards this goal.
There is work underway to produce an action plan to take this forward.
There is some work to do and I will keep you updated as this progresses. In the meantime if you have any queries, please contact the dark sky co-ordinator.


This public house has non-polluting lights. All are pointing down and any scatter falls on the path outside

Street lighting has improved enormously in Cardiff. The side of the National Museum manages with just good street lights to be attractive

The wall lights in Queen Street reflect the historic nature of the street and manage to keep light beams to below the horizontal.


City Hall Cardiff (17,800 watts) and National Museum BEFORE it was floodlit.

Fashion fad up lights around City Hall entrance. What is their purpose?

These ground lights were installed to light the statue of Lloyd George opposite the museum. Can you see it? When the lights stopped working because of a fault, a councillor requested that they be repaired! The light behind the statue is a street light.

Globe lights with no upwards shielding. Half the light goes up. Some globe lights do have this, by St David's Hall, for instance.

Trees in Queen Street and elsewhere are up lit whether they are in leaf or not and in any case most of the light shines up and is wasted. The little creatures whose habitat this is are disturbed. This particular tree has since died.

These circular lights set in the steps going down to the Llandaff Cathedral shine into your eyes and fail to light the steps at all. Some might think that this modern look is, in any case, not in keeping with a heritage site.
