<br />6. Vse eneI'gy efficient light sources. Light sourc;;es vary greatly in their efficiency, Consider especially
<br />the use of low pressure sodium lamps; they are the most efficient of all, and they are also strongly
<br />preferred by astronomers as the light output by LPS is essentially all one coloI' and can be filtered out
<br />quite well. LPS is excellent for street lighting, parking lots, security lighting, and other applications a
<br />where color rendering is not critical. Careful lighting design can be done using LPS fQr essentially any"
<br />application.
<br />
<br />V. It All Works! Such quality lighting design has been used foI' some time now in many locations. Such
<br />cities are benefiting by beneI' lighting for their citizens, by a great deal of energy savings, and by darker skies
<br />(but not darker streets), We all really do win,
<br />
<br />One way to effectively begin is for cities to appoint an Outdoor LightingWorking Group to consider the
<br />issues and to recommend specific solutions (including lighting control ordinances) tailored to local needs.
<br />Such "committees" have been quire effective in a numbeI' of locations. Most of those active in both the
<br />astronomy and the lighting communities appreciate the advantages of good lighting and are eager to help
<br />implement them, Organizations in both these communities have committees on this topic.
<br />
<br />VI. So What's the Problem? The main problem is that there is still a vast lack of awareness of the issues,
<br />the problem, and the common sense solutions, Education is the main thrust of most current activities. The
<br />second large problem is apathy, Even with awareness, action is needed, Some consider it too big an issue to
<br />become involved with, other feel that it is not important enough, Neither is a good enough reason for apathy.
<br />
<br />VII. Help Is Available. The relatively new International Dark-Sky Association, a non-profit organization,
<br />has been formed to help with the educational efforts. It is a membership based organization with members
<br />now in 56 countries. IDA has produced many Information SheeU discussing the issues, as well as slide sets
<br />.oIIIIIi:d other material available fOr those who want to become informed and who want to help spread the word
<br />_others, There is a slowly growing awareness of the problems, and of the solutions, but much more
<br />educational outreach is needed.
<br />
<br />e
<br />
<br />VIII. Conclusion. There is a problem, and it is still getting worse most everywhere. However, there are
<br />solutions, and they work. They also improve the quality of our nighttime lighting, and they help us save a
<br />great deal of energy and money. Lack of awareness and apathy are the main problems, Action is called for.
<br />The conclusion is that: We All Win.
<br />
<br />IX. Thanks! Please do help us build awareness and overcome apathy, everywhere. The stars and the
<br />universe need your- help. Help US save the stars!
