SLFTL Tubular Daylighting System

LightFlex™ Tunable-White LED Tubular Daylighting System

LightFlex™ LED is the industry’s first commercial daylighting system with integrated tunable-white LED and lighting controls — providing natural light, electric light, or a combination of both via the same luminaire. Watch Video

For ultimate energy savings, the integrated daylighting sensor and nLight® controls system work seamlessly together so the LEDs can supplement daylighting coming through the tubular daylighting system when more light is needed. See Demo

Lightflex™ LED tunable white is perfect in indoor applications such as classrooms, offices and conference rooms as it allows the LED light color temperature to be adjusted by the user, supporting circadian rhythm and tasks such as reading, meeting, teaching and more.
