LED streetlights have been such a boondoggle. They're a major source of light polution, and their supposed reliability and cost savings is turning out to be a fiction.
LPS is such a better technology for streetlighting but sadly the sudden swing to LED has made commercial production of the bulbs non-viable (esp. as LPS lamps actually are long lived, and so are replaced infrequently) and so even places that realized that the benefits of LED streetlights were largely fiction have found themselves forced onto the inferior technology.
- solarkraft 4y agoWell, why is LPS (low pressure sodium for everyone playing along at home, took me a bit of googling to find) better for street lighting and street lighting only? I like their light, but presumably if they were better they would be used, wouldn't they? Edit: There's some nice information at http://lamptech.co.uk/Documents/SO%20Introduction.htm http://lamptech.co.uk/Documents/SO%20Introduction.htm
- nullc 4y agoThey don't render colors, makes them unattractive for general lighting applications. They're exceptionally efficient and cost effective, however. Many people, myself included, find the limited color spectrum makes much better at not destroying nightvision and lack of blue light results in clearer seeing (while the blue-heavy light from LEDs is particularly bad).
