Default adding some HID lights to greenhouse

We are commercial growers of hydroponic tomatoes. We grow them under plastic. We are thinking of adding some HID lights to supplement the limited sunlight we get in New England during the winter. Does anyone have any advice or experiences in terms of types of lights to get; metal halide sodium, agrosun, etc., height from plant, length of time to leave lights on, differences in yield, ir cooled v. water cooled, etc? Thanks. Mike
