- jkmcf 10y ago20+ years ago, sodium (?, same as below?) lamps were suggested but supposedly people didn't like how things looked (IIRC) in the light. http://www.flagstaffdarkskies.org/for-wonks/lamp-spectrum-light-pollution/ http://www.flagstaffdarkskies.org/for-wonks/lamp-spectrum-li... says low pressure sodium lamps significantly improve star viewing compared w/ LED due to the narrower spectrum. Downvote science, bitches.
