The town of Langen near Bremerhaven is one of the first German municipalities to switch its street lighting completely to LED.
It started with a successful pilot project, installing LED lighting in the town hall carpark.
Switching the rest of the street lighting will cut energy consumption by around 62 percent and reduce CO2 emissions by some 473 metric tons a year.
With additional savings on maintenance, the investment will be recouped in as little as around ten years.
Thanks to modern control technology, the brightness of the lighting can be lowered late at night, whereas in the past the lighting along certain stretches of road was completely deactivated
