PG&E has some 200w HPS NEMAs in use. They have a deeper optical assembly similar to the LPS NEMAs.
Do you have any pictures? I would be interested in seeing this. If I do order one, it will probably be 100w metal halide (with a mogul socket) but if it doesn't cost too much more I might get the HPS. If I order it in metal halide, do they come with enclosed refractors? I don't want to order it with a mogul socket only to have it come with an O-rated socket (they don't make protected mogul base low wattage PSMH lamps).
