It would seem kind of strange if you were driving on a back road at night, far from any known source of electricity, when you suddenly came across a working streetlight.
Such a thing is possible, however, and could even become a common occurrence. That’s because Lighting Science Group now manufactures solar powered LED streetlights, that can run entirely independent of local power grids. Even if the availability of electricity isn’t an issue, Lighting Science states they are also brighter, more efficient, and require less maintenance than regular HID streetlights. Those claims obviously impressed somebody, as the company’s PROLIFIC Series Roadway streetlights are now being installed on a 23-kilometer (14-mile) stretch of Mexico City’s elevated Viaducto Bicentenario superhighway.
Lighting Science says their 100-watt, 5000K Roadways are at least 50 percent more efficient than HIDs. The lights are designed to run off a low-voltage direct current source of electricity, which could come from either solar or wind power.
