Also led streetlights suck almost as bad as led headlights.
They are very bright.
It's harder to get the older style mercury vapor bulbs these days. They need to convert the hardware to LED sooner rather than later. They did it on 3rd street and a few other places downtown, but it's pretty much not happening anywhere else that I can see.

They are about to replace the all the lighting on the I-10 project in Baton Rouge with LED.
If the older style bulbs are so hard to get, they should take the ones that still work from that section and use them in the thousands of other places where Entergy’s street/highway lights are not working.

Brightness isn't everything.
The led light is no longer similar to blackbody radiation, meaning it's a set of discrete wavelengths, not a continuous spectrum.
Similarly, It's also often polarized in weird ways instead of a random distribution.
What does this mean? It's why led light in high humidity or fog often reflects more than refracts, and some of those wavelengths might make it through the fog while others don't. It blinds you relative the old style faster than adding more light helps.
Then if the light is somewhat polarized, it might get filtered funny by your windshield ( turn your head with polarized sun glasses on while looking at an led screen to see an example of this).
It's why so many people today think their night vision is getting worse. Causes more eye strain at similar light levels. No it'snot your vision, it's just the light sucks.
