60 watts to illuminate just one room used to be the norm. Now it sounds insane. Maybe losing the perfect color rendering index was a worthwhile tradeoff after all.

Street lights use sodium-vapor fluorescence rather than incandescence, which was actually more efficient than LEDs until a few years ago (and I believe that low-pressure sodium-vapor still is and only high-pressure sodium-vapor has been surpassed by LED tech).
So there isn’t all that much power freed in replacing existing street lights lamps with LED.
However that tech doesn’t really work well for lower power application such as home use, hence why people used to have 60W incandescent lamps at home or their fluorescent lamp equivalent (which is around 20W) that were replaced by first 10W LEDs and now even lower as LED light bulb tech has improved.
