> Even 10 years after college I distinctly remember the look of Flagstaff at night. Namely because the city was effectively grayscale and it was beautiful.

San Jose used to look that way too. There are still pockets of LPS lights here and there, but since most makes are not commercially available anymore as of this year you can expect they'll vanish fairly quickly.

Such a loss, LPS streelighting was very good. I hope the narrowband amber LEDs are a commercial success.

Anyone know where there are fixtures with them available in small quantity? ... I stocked up on LPS bulbs before they went unavailble, but they won't last forever.
