SLFTL2 Tubular Daylighting System

LightFlex Dual-Tube Tunable-White LED Daylighting System

by Sunoptics

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

The LightFlex LED Duo system consists of two highly-reflective (98% reflective MIRO-SILVER®) tubes extending from one roof penetration, to deliver natural daylight and/or electric light to two luminaires. It delivers the same amount of light as two single tubular daylighting devices (TDDs), but with only one skylight.


LightFlex LED uses our 3-step system (Capture, Transport and Distribute) to optimize daylight when available. 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® wired controls enable the sensor, louver and luminaire to adjust, supplement, and maximize natural light and tunable-white LEDs.

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