What measures we installed


All of the manufacturing floor high-bays were replaced with high efficiency GE LED fixtures. These luminaires came equipped with integrated Daintree sensors and controls.

"The lights made a tremendous difference in our shop.... when parts come off the machines the team can clearly spot any defects or imperfections before going to quality control"

- Keith Heinonen, Facility Manager.

How these measures benefited Columbia Manufacturing

Columbia benefited from a large reduction in operating and energy costs. The new equipment installed increased foot candles and color-rendering making for a safer and more productive working environment. Upon completion of the job, all products and workmanship are fully warranted by Greenleaf for 5 years.
