This web site is to promote the control of light pollution of the night sky. I am fortunate to live on the edge of the village of Lurgashall, which is in the countryside north of Petworth, West Sussex. Our location is protected from the major sodium light pollution of the nearest large towns by the Blackdown hill to the NW, Bexley Hill to the WSW and the South Downs to the south - this does mean that we can't see the low horizon which you can from the top of the South downs. However, we still suffer from the so called halogen 'security lights' that blast light upwards in the most uncontrolled directions. (Yes I do have low energy 10watt fluorescent outside bulkhead lighting)
The 3 classes of light pollution are
Light Trespass: intrusive light onto other people's property
Sky Glow: the glow that prevents observation of the night sky (LP sodium orange can be filtered)
Glare: unshielded light reducing vision of objects in the direction of the light
So please think carefully before choosing and siting lighting - and remember good design that directs the light where it is wanted (Full Cut Off FCO) and not up into the sky is more efficient as well as more neighbourly.
