A wealth of knowledge and expertise on responsible lighting and best practices exists among the astronomical community and its associates. The AAS Committee on Light Pollution, Radio Frequency Interference and Space Debris would like to host a workshop to share that knowledge with the astronomical community. The workshop will be designed to share information that people can put into practice. Jeff Hall (Director, Lowell Observatory) and Lori Allen (Director, Kitt Peak National Observatory) will help facilitate the workshop, as well as staff from the International Dark-Sky Association and Chris Monrad from Monrad Engineering. McDonald Observatory/UT Austin has also been invited.

A three-part session format within a three-hour period is being considered: a plenary overview at the start, followed by breakouts at individual tables in round-robin fashion, and concluding with a panel discussion on best practices for specific themes (LED conversion, health impacts, codes). The tables would be hosted by the organizations mentioned, who would also serve on the discussion panel.

The workshop will showcase successful outcomes with real before and after data and an expectation that going forward, communities can make progress in reducing light pollution. Easy to adopt roadmaps could be made available, as a motivator to action. This would be balanced with sanity checks on the difficulty and resources needed. As an example, McDonald Observatory had a program that acquired donations to pay for Hubbell Sky Caps and arranged for the utility company to replace several hundred units for the plastic refracting lenses on dusk-to-dawn fixtures. As another example, Lowell Observatory has been working with consultants, Monrad and Benya, to find a dark-sky-preserving solution for converting Flagstaffs current streetlights (70% LPS, 30% HPS) to LED. The approach and solution being developed by Flagstaff is intended to be a model for picking types of LEDs best for a community.
