230V 1ph in Vienna, neutral and two switched hots (one of which is hot dusk to dawn, the other only dusk to 11 or midnight), double-isolated lights, mostly two 35W fluorescents, HPS or some mercury vapor in busier streets (generally HPS, warm white mercury in historic areas and places with lots of pedestrian traffic). The lights are switched in zones controled by photocells and can act quite weird sometimes. Either they're on all day long or they shut off completely at midnight (and sometimes switch on both circuits at like 3AM), or both hots are on all night, or they don't work at all. Especially the area I live in has had quite some fun over the past 5 years (ever since they disconnected a larger section of overhead wire to allow for fire department ladders a few streets away).
