Philips LED T12 retrofit

-can be had in versions for magnetic ballast or electronic-they work great and are T8 diameter.High pressure sodium lamps are dramaticly superior to LED for roadway lighting-a local overpass/intersection was recently completed and the builder had enough sense to use HPS-insuring proper,effective and safe illumination.Back to "good"use of LEDs,noticed Feit has some big globe"retro"LED bulbs that have a helical"filament"of phosphor coated strip LEDs-so far have hot ben able to get myself to spend $35 on something made in china,but is tempting to try one out.
 
"city" lighting is INCREDIBLY wasteful

True, but in climates with snow and ice hazards, street lighting makes walking outdoors after dark much safer.  I can't imagine walking outdoors in the winter without it.

 

Our LED replacements left a lot of dark spots.  HPS was already very energy efficient...I suspect the LED replacements were probably undersized in an effort to reduce the project payback time.
