LET THERE BE LIGHT EMITTING DIODESUncategorized, by Catherine Higgins.
LED fixtures installed near the Salt Lake International Airport will provide low maintenance, energy saving bright light.
UDOT crews will install LED fixtures on highways in Region Two, starting with fixtures on the I-80-Bangerter Highway Interchange near the airport. LEDs emit white light that “Produces far more color within the color spectrum” which allows drivers to see roadway objects more clearly at night, explains Richard Hibbard, UDOT Traffic and Safety Signal and Lighting Engineer. LEDs have been installed in several locations along the Wasatch Front, including Foothill and 7th East in Salt Lake City, on 13th East in Sandy City and on 6200 S in Holladay.
The more efficient, long lasting fixtures will save costs. A typical 400 Watt HPS fixture costs UDOT about $10 per month. Considering that Region 2 alone has about 1,000 400W fixtures on the Rocky Mountain Power grid, anticipated savings could be as $5 thousand per month. LED fixtures are expected to last 20 years or longer with no maintenance at all. Standard fixtures need to be replaced every five years.
High mast fixtures are still in development. “When manufacturers begin producing viable, cost-effective LED fixtures for high-mast, then we will begin a replacement program for that system,” according to Hibbard. “I don’t anticipate that happening for at least two to three years.”
