But DT is the center and heart and should be lit at night. If the rest of the city reduces light pollution by say 25% even if DT is the brightest part of the city that will still shrink the amount of light pollution in the Austin area. Also there are ways that buildings can be lit that reduces light pollution such as above light coverings and aiming light in such a way that there isn't a lot of residual light escaping.

Those awful outdated sodium vapor orange "cobra head" street lights, and especially those giant high mast tower lights used on interstates are the big culprits of light pollution. Moving to LEDs that are properly shielded and angled will continue to cut down on this, but we got a long way to go.
Decorative LED strips, landscape lighting, and properly angled colored LED "wall washes" are not a significant contributor to light pollution.
