What are the benefits of LED streetlights?
Less energy - LEDs use 50% less electricity than traditional high-pressure sodium (HPS) lights.
Reduced Light Pollution - NorthWestern offers a full range of dark-sky-friendly LED options. With LEDs, the light can be better directed to where it is needed – on the street and adjacent sidewalks.
Improved visibility - Old HPS lighting produced an orange-yellow light that does not render colors well. LEDs, on the other hand, output a fuller light spectrum that renders colors accurately.
Lower operation costs - LEDs require less energy, and, because they are more efficient, they also last longer and need to be replaced less often than HPS streetlights.
Improved safety and security - The new lights give increased safety at night through greater visibility and fewer streetlight outages.

Wherever possible, we used lights that are dark sky compliant, and the vast majority of the new LED lights are dark-sky compliant. They also meet any local lighting ordinances. For more information on dark sky standards, click the button below.
NorthWestern recycled the old high-pressure sodium lights through Four Corners Recycling in Bozeman. Four Corners recycled all parts of the old lights, including the metal heads, the glass lenses and the bulbs, some of which contain mercury.
