Guidance for the Reduction of Light Pollution

 The CfDS has produced its Lighting Guidance and Advice document (available as a pdf file), which has been compiled by the committee of the Campaign for Dark Skies, whose members include professionals in astronomy, physics, lighting, engineering, health and the law.

 Following this advice will save money and energy, ensure an efficiently lit environment with the right amount of light only when and where needed, add to safety, promote better health and minimise the amount of light wasted into the night sky, allowing everybody to see the inspiring view of a night sky full of stars.

Government document, Lighting in the Countryside: Towards Good Practice

This guidance was published jointly with the (then) Countryside Commission. It gives advice, which is also relevant in towns, on good lighting types and installations for street, sports and security lighting. It describes how to avoid light pollution of the night sky, glare hazards to drivers and nuisance to neighbours. It also offers design guidance and a bibliography.

However, it should be noted that the ILE guidelines are more technical in nature, and erroneously suggest that relatively high levels of light pollution should be acceptable in built up areas despite the serious detrimental health effects that inner-city all-night lighting has on the urban population.
