AirGlow controls sustainable streetlights for coastal town

How wireless lighting control maximises energy savings

By combining POLAB’s durable luminaires with reliable wireless control from LumenRadio’s AirGlow, the coastal town of Smögen was able to modernize its street lighting in an extremely demanding environment.

Sotenäs, the local authority in charge of Smögen, started looking for a long-lasting lighting solution that would:

-Withstand the coastal environment
-Reduce energy consumption
-Minimize light intrusion into nearby homes
-Give them adaptable lighting in areas with low nighttime activity
-Their existing system consisted of 50–70W high-pressure sodium luminaires installed along narrow streets and residential paths close to the sea. Sotenäs replaced these with POLAB’s Valdur.

Valdur is an innovative luminaire which has won awards for its design. It is made of an extremely durable, scratch-resistant material which has a much lower CO₂ footprint than die-cast aluminium. Valdur also has LumenRadio’s AirGlow technology integrated giving lighting manager wireless control over their streetlamps via a simple app.

Around 100 Valdur’s were installed and Sotenäs saw an immediate improvement in efficiency, with the new LEDs using only 22W per fixture. Compared to the sodium lamps, which were drawing up to 80W with drivers, this was an energy reduction of 72%.

Johan Johansson works for Sotenäs Municipality and was the Operations Manager for the Smögen street lighting project.

“We have a very demanding coastal environment and we needed luminaires that could handle it,” he says. “We know that every luminaire we replace saves energy – and with wireless control you can save even more.”
