So there's been some discussion and plenty of resources that have been passed along on this group in the past few days. 

I'm curious, what's on everyone's wish list? Someone mentioned a dark skies initiative. What would you like to see in any initiative and some goals or aspirations to come out of it? 

Others have mentioned more enforcement of lighting codes. What kinds of benefits could there be if there was more of that enforcement? How could it help others understand better if they have a different belief on the topic? 

And, is there anything you hope to learn more about regarding dark skies? What are some things you've learned over the years about the topic that stand out to you? 

Just an FYI, I went to Great Sand Dunes NP a few days ago hoping to do some night sky photography.  What I found was an incredible amount of light pollution, so much that I didn't even try.  Black Canyon is a much better location for astrophotography.

• If any of you are interested in improving the existing lights that you own, check out https://www.darksky.org/our-work/lighting/lighting-for-citizens/lighting-basics/
• As far as actual lighting fixtures, Home Depot has a good  selection.   See  https://www.darksky.org/our-work/lighting/lighting-for-industry/fsa/retailers/
• I replaced 4 lights at a friend's house for under $150 and a couple hours of my time.
• Don't forget to use LEDs, but follow the guidelines in https://www.darksky.org/our-work/lighting/lighting-for-citizens/led-guide/
• The 'color' of a light, LED or otherwise is measured in Correlated Color Temperature (CCT).  Note that, somewhat illogically, lower temperature colors are 'warm.'  I won't bore you with the reasoning...
• All LED bulbs sold now must state the CCT on the packaging.
• The LED that the city has been installing are 5000K...bright blue-white.  If you want to see what a 2200K light is like, drive through The Bridges.  These are high pressure sodium lights.  They will eventually have to be replaced.  The best choice would be 2200k LEDs with proper selection of light output.

Paonia has been working toward Dark Sky Community designation.  In the process, they worked with DMEA to inventory and replace (eventually) all the streetlights with Dark Sky compliant lights.  There is no technology barrier to using better lights for mitigating light pollution.  I have less information about the cost.  Perhaps Aaron Watson has info for Paonia.
