The Boulder Chamber of Commerce and volunteers from local businesses are working together today to perform an energy efficient upgrade on Boulder's Flagstaff Holiday Star.

Coordinated by volunteer caretaker Craig Reynolds--the owner of Lord & Reynolds Electrical Services-- the group replaced 365 existing 40-watt standard light bulbs that make up the star with 6-watt Cree LED bulbs, according to a news release.

The new bulbs are 85 percent more efficient, according to the release, and could last up to 42 years as part of Boulder's illuminated holiday tradition. They are also designed for durability and are expected to withstand the elements on Flagstaff year round.

The upgrade was made possible by a donation from Citywide Banks, according to the release, and the bulbs were provided by Polar-Ray.com.

The Chamber plans to illuminate the star for the first time this season at 7 p.m. on Monday, the release said. The lighting, taking place on Veterans Day, is meant to serve as a special tribute to America's armed services.

"This is a milestone year for the Boulder Holiday Star," Boulder Chamber President John Tayer said in the release.

"Thanks to our partner, Citywide Banks, the masterful coordination by Craig Reynolds, and the arduous efforts of a committed volunteer crew, we are taking the Holiday Star into a new era of energy efficiency. We also look forward to a new tradition of honoring our military men and women with a glowing tribute to their service and a fitting kick-off to the Holiday Season on Veterans Day."

Tayer said Monday's lighting will be the earliest the star has been illuminated in his recollection, but he couldn't be sure if it was the earliest lighting that the city has ever seen.

The Flagstaff Star has been a Boulder holiday tradition since 1947, according to the release.
