HPS lamps are more efficient than most MH lamps, and they maintain their
luminence better as they age. Normal HPS lamps have a color temperature
somewhere around 2000K and a CRI of about 20. So I think they would
look terrible (like those pinkish-yellow street lights). There are
deluxe HPS lamps available that have color rendering of about 65, but
their color temp is still so low that I think they too would suck.
