LED are starting to be offered in retrofits here, but mostly the Metro is still using MH, and on main roads a mix of MH and HPS ( bulb on truck mixed willy nilly) are common. On residential roads there are still relampings with 80W mercury lamps , lower power is winning out over the high cost of the LED modules. There are a few low power LED fittings, but they are rare. City hall accent lighting is with CFL lamps ( I know.......) and the odd MH lamp.
