Photo/TOM CLARIDGE LIGHTS EXCHANGE: Paul Ferris holds a box containing a 70-light string of stateof the-art outdoor LED lights that he was told will use just four watts of electricity, compared with the seven to 15 watts consumed by a traditional incandescent ornamental light. He was one of many environmentally sensitive consumers who exchanged old sets of lights for new ones provided as a public service by Orangeville Hydro. Serving the public at the Orangeville Mall display counter are (left to right) Amy Proctor-Long, Taylor Nichols, Kim Brooks and Amanda Davis.
