LightTube
Tubular Daylighting System – a compact, highly reflective daylight delivery solution that brings natural light into interiors with minimal heat gain.
Overview
LightTube collects sunlight through a UV-stable dome, channels it along a highly reflective tube and diffuses it into interiors. Ideal for residential and small commercial applications where roof penetration area is limited.
Why choose LightTube?
- High-efficiency light transfer
- Low maintenance and weather resistant
- Minimal thermal transfer into the building
