Solar Powered LED Streetlight

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.

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.
