New LED Streetlights Install...
New LED Streetlights Installed for On-Site, Real-Time Inspection
The pilot phase of the City’s LED retrofit project is underway, with 17 intersections and stretches of roadway outfitted with new LED streetlights for project contractor Siemens, City staff and residents to analyze.
The sleek cobra head fixtures seen here on Magnolia Avenue (left) replace fixtures up to 30 years old that are remarkably heavy and contain inefficient high pressure sodium (HPS) bulbs (right). HPS bulbs cast a dim, orangey light that seems to illuminate the air more than objects. Apparently, neighborhood starlings prefer the older model.
The whiter, clearer light of LED bulbs is designed to make objects more visible and, therefore, environments safer for drivers and pedestrians. You can see how important visibility is at busy intersections like this one at Chilhowee Drive and Asheville Highway.
That makes this a good location to test the LED lights in the cobrahead fixture and their effectiveness. Here's a close-up of one of the fixtures in that location:
A recent visit to these pilot locations illustrated just how much lighting products have changed in recent years. As brand new technology is implemented among old and not-so-old tech, our streets and parking lots are illuminated in a variety of shades.
For example, near the Broadway and Highland Drive pilot location, you can see the difference in the old City HPS (left), an LED flood light at CVS Pharmacy (right), and the new LED street light installed across the street (below).
The mix of LED bulbs on the market runs the gamut of colors a.k.a. color temperatures. The color temperature of the CVS bulb is bluer, or cooler, and would have a higher color temperature value than the City LED, which was chosen based on industry best practices.
Do you live, work or play near one of the small-scale LED demonstration areas? You can see them
