Streetlights That Adjust To Moonlight   Streetlights that adjust
their light output according to the phases of the moon — this
design idea was the winner of Metropolis Magazine’s Next
Generation design awards. These streetlights would have light
sensors built into them that are sensitive enough detect the
brightness of the moon, and dim themselves accordingly. For
example, if there was a full moon with a clear sky, the lights
would be dimmed to 10% of their power, whereas a moonless night
would mean lights come on at fully intensity. Since the
streetlights would also make use of energy efficient LEDs, the
combined savings would be 90-95% over a traditional streetlight.

them and let them charge up all day and you REALLY have a
streetlight.  Leave a Reply
