Okay, maybe deathmatch is a little bit much, but Howard Brandston, one of the lighting industries superstars (with over 50 years and 2500+ projects) is certainly not a fan of high pressure sodium light. I just ran across a New Yorker article about Howard Brandston discussing some sodium vapors (and other stuff) on a walking tour in NYC. Howard calls HPS “the lamp of least choice.”
It IS ugly.
Check out the article at The New Yorker. I am pretty sure I got this from Craig over at LightNOW.
