In 2014, we upgraded our lighting system plant wide. This upgrade included motion sensors on every light ballast so that unoccupied areas are not unnecessarily over lit.
All high-bay HID lights were changed to T5 fluorescents. All outdated bulbs in the offices were switched out to lower consuming T8 bulbs, and all high-consuming magnetic ballasts were changed out to high energy efficient electronic ballasts. We recycled almost 100 lightbulbs at Batteries Plus and 130 pounds of old ballasts at Joseph Simon and Sons.
Our exterior lights were all changed out in 2015 to LED retrofits reducing our energy consumption by nearly 68%. These lights last more than twice as long as the high intensity discharge lights they replaced.
