Publications From Our Group

Our team creates publications and presentations for our various outreach efforts; some of these items we will make available for general distribution. We invite others who are involved in responsible outdoor lighting efforts to make use of them in their own outreach, and copy and distribute as needed to promote our intended causes. All we ask is that you do not alter their content, and leave credit to our group and our I.C.R.O.L. copyrights in place.
