Forward-thinking Scandinavian country, Norway has introduced a revolutionary new dimmable LED street lights that automatically adjust their brightness when a car passes, in an effort to reduce its carbon footprint!
Indeed, there’s a certain 9-kilometre section of highway near the capital city, Oslo, upon which the street lights are able to dim to just 20% at times when there are no vehicles on the road or pedestrians taking a walk.
The municipality of Hole, where this energy-saving lighting installation has taken place, is well known as one of the traditional landscapes from the age of the Vikings, playing a prominent role in the Norse sagas.
However, it’s possibly more famous as the ancestral homeland of Norwegian author Jo Nesbø’s troubled detective Harry Hole, and the place from which his family name originates.
The ‘smart’ LED lighting system works by sensing cars, cyclists and pedestrians as they pass by, using 220 radar sensors that are attached to each pole. Thus, movement causes each light in turn to increase its brightness to 100%, thereby enabling the road-user to see what’s directly ahead of them.
When the vehicle has passed by, the lights dim again to 20%, which means they’re saving a massive amount by illuminating fully only when they’re needed.
LED Energy Savings
It has been calculated that by doing this, the 5-mile stretch of road alone can save a whopping 2,100 kW/h per week, which would amount to approximately 3.2 years’ worth of viewing on a large plasma television (figure based on the Energy Saving Trust’s study – Powering the Nation).
While this idea really isn’t anything too radical – we’ve been using energy-saving motion-sensor outdoor floodlights for years…it is, nevertheless, quite unusual for a country’s government to implement such a large-scale scheme and for such environmentally altruistic reasons.
Better For The Envioronment
But it shouldn’t be so, because LED lighting drastically reduces CO2 emissions by consuming less power than equivalently bright bulbs like the halogen and fluorescent models that were traditionally used for street lighting.
Admittedly, the Norwegian government has shelled out quite a few Krone to pay for the installation of this LED lighting system, however, Norwegian speed skater and YouTuber Bjørn Nyland reckons the costs will be recouped in just four and a half years.

But it doesn’t have to be just Scandinavian countries saving money and the environment with LED lighting…you can too! Simply replacing your old halogen, fluorescent and incandescent light bulbs with energy-efficient LEDs, your home will become less wasteful and you’ll save up to 80% on your lighting bills as well!
