Mack Technologies Completes Largest Manufacturing Facility LED Light
Retrofit in New England

Installation Significantly Reduces Energy Consumption, While Enhancing Profitability and Employee Working Conditions, with New LED Lighting Retrofit

WESTFORD, MA, April 10, 2013:  Mack Technologies, a leading provider complex of contract manufacturing services announced the completion of a major energy efficient LED lighting retrofit initiative that will substantially reduce energy consumption in their Westford, Massachusetts manufacturing facility.  The retrofit, performed by Bluestone Energy, has the distinction of being the largest retrofit deployment of LED lighting in any manufacturing space in New England.

The LED lighting retrofit helps Mack Technologies meet new environmental sustainability goals, cut costs, and significantly improve employee working conditions. 

Bluestone not only replaced 2,600 T-8 fluorescent bulbs with high efficiency LED fixtures in Mack’s manufacturing space, but also replaced several hundred older fixtures with high-performance T-8 bulbs in Mack’s offices.  Savings from the new lighting system were further increased by more than fifty percent by using state-of-the-art wireless controls on all lighting.  The intelligent controls are responsive to variable lighting needs and adjust automatically to provide more or less light as required. The installation process across Mack’s 108,000 square foot facility required 3,000 person-hours of labor. 

Mack Technologies will save over $50,000 in annual lighting costs and will receive over $130,000 through a combination of state and federal tax credits and utility incentives provided by National Grid. The LED lighting project provides Mack Technologies with a two year payback for all invested capital.

 “Concerns about initial cost, relative youth of the industry, and LED illumination characteristics made some manufacturers cautious about conversion,” said Paul Maher, Facilities Manager at Mack Technologies. “Our decision to move forward was based on a careful assessment of LED lighting quality and cost, as well as our desire to be a leader in corporate social responsibility.”

“We’re pleased to help Mack Technologies convert to LED technology and reach their environmental, energy, and quality goals,” said Ryan Blair, President at Bluestone Energy.  “ Through our Lighting Division Mack Technologies has decreased its energy lighting costs by 40%, met strict industry lighting standards, and improved both manufacturing-space illumination and facilities appearance – all while earning payback on its financial investments within two years.”

Over the next year, Mack and Bluestone plan to collaborate on more sustainability projects - continuing Mack’s goal of reducing its energy consumption and achieving its environmental sustainability goals.
