That's a 1985-1987 M-250R2 with the metallic/foil NEMA tag. I guess it's lived a good long life compared to some new HPS fixtures that are being replaced after a few months of service but still, such a shame to see so many lights get trashed for no other reason that saving a few watts.

I normally would never agree with something DSA says, but this is an exception.
Myth #5: Energy savings from LEDs automatically means a lower carbon footprint, which is better for the environment.

Again, it depends on how light is used. Individual LEDs produce more light for less electricity (and less money) than most other lighting technologies. That’s not in dispute. But we only get carbon and cost savings if we keep the amount of light used the same. Unfortunately, that’s not happening (see the Jevons Paradox, above). If the paradox is accurate, the world will demand more light as the price of producing it decreases. That goes for both the electricity and the cost of the fixtures, which are rapidly decreasing.

Another issue is the dollar and carbon cost to produce LED lighting, and potential environmental concerns once the lighting becomes obsolete. Just as we worried about the disposal of CFL light bulbs and mercury contamination, we’ll have to deal with LEDs and some nasty heavy metals.

Lastly, “better for the environment” should also consider the impact of all this light (especially blue light), on plants, animals and human health. Unfortunately, it rarely does.

Any machine is a smoke machine if you operate it wrong enough.

It's not better for the environment at all. Lighting doesn't create carbon emissions, the power plants that generate the power used by the lights create the carbon emissions. The only time lighting creates carbon emissions is during production. And the manufacture of LEDs is far more complicated than that of "incandescent" lighting technology (HID, fluorescent, tungsten filament lamps, halogens, etc). The only person who benefits from these mass conversions to LED is the manufacturer because it gives people a reason to throw out tens of thousands of otherwise perfectly-working light fixtures.

I'm all for brighter lighting. There are few places that I'd consider "overlit". Even in my own home, I've been replacing 60W incandescents with 53W halogens. I get more light without using any more electricity. And once the cost and size of 100W= LEDs come down, I'll probably upgrade a few fixtures to 100W= lamps. I suppose lighting within a household is a different animal from outdoor lighting though, since indoor lighting minimally affects plants and animals, unless you have lights shining out big picture windows into the trees lol.

I think that repair/maintenance of "old style" light fixtures is easier and cheaper than current LED ones because some/most/all of the parts are standardized.

Few utility companies repair street lights beyond new lamps and PCs anyway. If it doesn't light with a new bulb and photocell it gets replaced 99.5% of the time. The lamps and PCs are standardized among manufacturers but beyond that nothing is the same. You can't take parts from an AEL cobrahead and put them in a GE cobrahead without some tinkering/jury-rigging, except for refractors.
