I can relate to that. To me, what's most galling about the street and highway lights is that the people who choose what lights to install still continue to choose ones that let light out the sides. I know it's because those types are less expensive, so have a lower up front cost, but they also require more electrical power, so cost more to operate. The lamps that direct the light in a downward cone provide the same ground level illumination with lower power consumption. The operating cost savings cover the difference within few years. After that, it's net spending savings.
