NANOSUN™ SKYTUBE Tabular Daylight
Light That Runs
The Length of
Your Building
The SKYTUBE is not a single dome. It's a long rectangular light strip that sits on your roof and floods an entire factory bay, warehouse aisle, or large hall with natural daylight — from one end to the other. No electricity. No wires. Just sunlight, spread evenly across the length of your space.
Available in widths from 280mm to 680mm and lengths up to 4500mm — sized to match your exact roof bay.

How Is SKYTUBE Different From Circular?
This is the question most customers ask first — and it's a good one.
NANOSUN™ Circular | NANOSUN™ SKYTUBE | |
|---|---|---|
| Shape | Round dome | Rectangular strip |
| Light Pattern | Circular pool of light | Long strip — lights entire bay |
| Best For | Individual rooms, specific zones | Factory aisles, warehouse bays, corridors |
| Profile on Roof | Dome (raised) | Low-profile panel (80–175mm flat) |
| Roof Types | PEB, RCC, Tile | PEB / Pitched Roof |
| How It Works | Single reflector pipe | Multiple reflectors spread along length |
In simple terms: If a circular NANOSUN is like a spotlight from above, the SKYTUBE is like a tube light from above — only it runs on sunshine, not electricity.
How It Works
Three stages from rooftop to factory floor — zero electricity at every step.

Step 01 — Light Collector
Roof Panel
A flat rectangular panel sits on your pitched roof — low profile, barely visible from the outside. It collects natural daylight across its entire length, not just from one point.

Step 02 — Along the Length
Reflectors
Inside the panel, a series of aluminium reflectors (5, 10, or 12 depending on size) are spaced evenly along the length. Each one captures and directs light downward — so the entire strip is lit, not just the centre.

Step 03 — Full-Length at Ceiling
Diffuser
A continuous diffuser panel at ceiling level spreads the light softly and evenly across the floor below — like a long glowing ceiling panel, but powered entirely by the sun.
Product
Families
The SKYTUBE range is organised into three families based on width — each suited to different bay sizes and light requirements. Within each family, you choose the length that matches your roof bay.
Narrow Series
The slimmest of the SKYTUBE range. Ideal for narrow spaces where you need a continuous strip of natural light but don't have the roof width for a wider unit. Works well in corridors, along machine rows, and in narrow storage aisles.
Best for: Corridors, narrow factory aisles, single-lane bays, machine rows
Short and narrow — perfect for a small corridor or compact bay section.
