Acuity Brands, Inc. introduces the LightFlex™ system, a high performance prismatic daylighting solution for suspended-ceiling applications fromHR Tubular Sunoptics. The LightFlex system makes optimal use of daylight throughout the day, delivering glare-free lighting while minimizing energy usage from electric lighting. The LightFlex toplighting system uses the Sunoptics® Signature Series prismatic skylight. This skylight allows the system to efficiently capture low-angle sunlight and optimize light distribution. A unique, patent-pending optic sphere drives light down through the skylight’s light well, maximizing the system’s light penetration. The system comes standard with a conventional insulated square roof curb, which uses roofing industry-preferred flashing methods. For more information, visit or
