A manufacturer of equipment for ultrasonic welding and heat staking, Sonitek recently completed phase II of the project. Wanting to reduce energy costs, Sonitek replaced outdated light fixtures in the building. New reflector shades, T8 fixtures and electronic ballasts were installed.

With the improvements, the company expects to save 52,000 kilowatt-hours annually. Moreover, the new fixtures have improved lighting for workers.

"We're very concerned about environmental issues," says Jerry Daniel, operations manager at Sonitek. "Our products help customers cut down on waste and eliminate consumables, fasteners and solvents. We thought it only appropriate to implement money-saving, environmentally friendly processes in our own plant."
