Gregory's Server@davidho You hear people complain that these points are very slow. Not surprising because I can't imagine that old streetlights with sodium or sodium/mercury lights would have drawn more than 1 kW and that's peanuts by EV standards.
Ironically the old sodium streetlights, that were invented by Marcello Pirani's group at the Phillips Research Centre in the 1930s, remain some of the most efficient light sources ever invented, running at about 70% conversion. #ClassicKit https://www.chemistryworld.com/opinion/piranis-gauge/5039.article

@sellathechemist @davidho That's very good! Probably comparable to LEDs equipped with phosphor conversion. But of course, longevity. It's a big thing to not have to have a guy with an access platform on standby to replace lamps when they go. Bigger cost item than the kWhs!
