Longtime New York luxury wholesaler Davis & Warshow converted its 209,000-sq.-ft. Queens facility lighting from fluorescent tubes to LED lighting and became the first facility in the U.S. to reach net zero lighting costs with LED tubes and the largest single-facility LED tube installation with the best energy-efficient lighting per sq.-ft. in the country.

Davis & Warshow was able to reach the net zero lighting benchmark in part because of a rooftop solar array installed in 2011.

Davis & Warshow PresidentDavid Finkelnoted it cost more than $250,000 to convert to LED, but at the ceremony at company headquarters Con Ed executives presented Finkel with a check for $63,704, representing rebates earned for the conversion based on annual kWh saved using Made in America fixtures.

The LED conversion and solar array are part of the company’s Practically Green initiative - a pragmatic program to going green that started in 2008.
