Smart streetlamps, however, are controlled from a central point to turn on and off, dim, and flash continually in an emergency, like a car. This is what five test "smart" streetlamps in San Francisco are capable of doing. Run by Pacific Gas and Electric, these lamps use 100 LEDs to produce light similar to that of a regular streetlamp.
The new streetlamps can send and receive data, so a central monitoring station--or even a cell phone that connects to a secure website--can remotely program them to turn on and off. Furthermore, the illumination can be changed (presumably during dusk or dawn), thereby decreasing overall power usage. Even if full power is used, however, each streetlamp would draw 127 watts, compared to 290 watts for regular streetlamps.
