|Recently, the Los Angeles Community College District has been making great strides into green technology and construction. One of these efforts is the implementation of street lamps which do not require any wires or any connection to the larger electrical grid. Currently there are 38 lights installed, lining College Boulevard as well as a few placed in nearby parking lots and near the athletic stadium. |
The new street lamps are solar powered. The posts themselves, identical in color to the rest of the campuses lights, are wrapped in solar panels which feed a battery placed at the base of the pole. The panels are efficient enough to supply the lamps with five days worth light simply from one day of sunshine. Seeing as how rainy, cloudy forecasts are rare in Southern California, there doesn't seem to be any great concern for the lack of functionality from these new lampposts.
Furthermore, the lamps actually have a sensor that can read when the lights can be put to greater use. For instance, if the street is empty and without any traffic—pedestrian or automotive—the lamps will automatically dim. If a car or person enters the given range of any light's sensor, the lamp will brighten. This way, the lamps operate much more efficiently, powering down whenever not in need.
The lamps cost $7,000 dollars each and have a life expectancy of 25 years. Over the years, this will prove to be less expensive than the current, wired lamp posts currently in use almost everywhere else.
