these are GE M-250R1 175w mercs at an apartment complex, leased from the city's municipal utility. the city streets have done away with mercs but the municipal utility still maintains PAL mercs and those in alleys.
Cheswick Borough, PA still has plenty of 175-250 watt mercury vapor GE M-250R1's along their residential streets and the street lights along the main road (Pittsburgh St) in that town are all 200 watt high pressure sodium.
