SLFOL Tubular Daylighting System

LightFlex Tunable-White LED Open-Ceiling System

by Sunoptics

The LightFlex™ LED daylighting system (SLFOL) from Sunoptics® delivers natural light into open-ceiling interior applications and supplements daylight with tunable-white LED technology. LightFlex LED is the industry’s first tubular daylighting system with integrated controls to provide natural light, tunable-white LED light or a combination of both — in the same system.

LightFlex LED supports ones’ natural circadian rhythm by providing access to natural light throughout the day. Ideal for interior classrooms, offices and conference rooms with no window access. SLFOL is designed specifically for open-ceiling applications to simplify its use in such applications.


For added energy savings, the embedded daylighting sensor detects the natural light and triggers lighting controls to adjust and supplement daylight, only when electric light is needed. Integrated nLight® controls enable the system to adjust, supplement, and maximize natural light and tunable-white LEDs.

Whether automated or manual, the result is an adaptable, fully-responsive visual environment. Click here for everything LightFlex LED!
