After nearly every fixture in my area was replaced with LED, the streets looked uglier. They are nothing but floating "spades" at this point. FCO HID was an exception but it still wasn't as classic as semi-cutoff HPS and MV cobraheads, which in my opinion looked the best. Why is the lighting industry making their abominations (LEDs) more abominable? Can they at least design them with a diffuser bowl instead of refractor like a semi-cutoff cobrahead? They don't even retrofit semi-cutoff cobraheads in my area, they just toss them. It is just wastefulness. I have seen better LED retrofits when I lived in Japan compared to the US. The retrofit consists of removing the ballast which is usually pole-mounted and then wiring direct power to the socket. After that, you just screw in a convex-shaped LED retrofit lamp that is shielded and it keeps the original look. They are also quite well-made, convincing me that these LED "convex" lamps are much better than the LED "COB" lamps that have a high-failure rate. In conclusion, my guess on why semi-cutoff streetlights are disappearing is because of "Dark Sky Compliance" and it looks like they show no signs of returning.
