Visa Lighting has introduced six models to its growing behavioral health collection, which includes fixtures with safe and therapeutic designs. The company’s new Symmetry models are tested to IK10+ standards, which means they can withstand more than 100 joules of mechanical impact. They are constructed with an additional 3/16-inch polycarbonate lens, which is fastened behind the minimal frame with tamper-resistant screws. Each model can be installed flush to a drywall/sheetrock ceiling and recessed 5 to 7 inches. In addition, Visa Lighting’s engineers have crafted luminaires that look more home-like and minimalist. For example, the tamper-resistant screws that fasten the frame and lenses to the ceiling structure are barely visible and painted with the same finish as the frame.
