For more than 75 years, the City of Hagerstown Maryland’s Light Department (HLD) has been dedicated to providing safe and reliable electric power at the most economical possible cost. Jason M. Bachtell, HLD’s Staff/Electrical Engineer, has been using Design Master Photometrics for about eighteen months on all types of lighting projects. “Lighting is time-consuming to get right, so we were looking for something that was less cumbersome than the manufacturer-provided photometric programs,” explains Mr. Bachtell. “Design Master Photometrics meets that need really well and lets us quickly lay out and evaluate different lighting options.”
