Overview

LightTube delivers natural daylight deep into industrial and manufacturing facilities, reducing dependence on artificial lighting and helping lower daytime electricity consumption.

Its UV-stable rooftop dome captures sunlight and channels it through a highly reflective tube before distributing bright, uniform daylight through the diffuser. Designed for manufacturing plants, warehouses, PEB buildings, industrial sheds, workshops, production areas, and storage facilities, LightTube provides an energy-efficient daylighting solution for large industrial spaces.

By maximizing the use of available natural light, LightTube helps reduce lighting energy consumption, lower operating costs, and improve visual comfort and working conditions—while making industrial facilities more sustainable and daylight-responsive.

Why choose LightTube?

  • High-efficiency light transfer
  • Low maintenance and weather resistant
  • Minimal thermal transfer into the building

How it works?

Light Collector

Highly durable and non-flammable polymeric material, UV resistant. Collects daylight from all angles and transfers light efficiently throughout the year.

Reflective System

Corrosion-resistant high reflectance coating transfers above 90% of light without colour shift, increasing output even at low angles.

Light Diffuser

Disperses light uniformly without bright spots, glare, or colour shift.

Installation Notes

LightTube is engineered for swift, leak-proof integration with metal trapezoidal sheets, standing seam roofs, and RCC flat slabs.

  1. Roof Profile Matching: Inspect roof profile and install custom factory flashing engineered to match the roofing contours.
  2. Dome Positioning: Position the collector dome to maximize unobstructed sun path and avoid rooftop obstructions.
  3. Reflective Tube Routing: Maintain straight tube runs with minimal bends to ensure maximum 90%+ light transfer.
  4. Weatherproof Sealing: Fasten with EPDM gaskets and industrial-grade sealants to ensure 100% water tightness.
  5. Diffuser Fitting: Mount the optical diffuser flush at ceiling level for smooth, uniform illumination.
