I read that high pressure sodium lighting, the kind used to illuminate streets and parking lots, is very effecient, 140 lumens per watt. That represents a substantial cost saving over other types of lighting, such as incandenscent or fluorescent. The only drawback is the monochromatic amber color, but I figure I can get used to that. I mean, how important can it be it to see colors in the home? Will I have a hard time persuading my wife to agree to this?
