Simple Structure, Reliable for Decades
A rooftop dome collects natural light, a highly reflective tube carries it indoors, and a diffuser spreads it evenly. With no electrical parts and no moving mechanisms, the system needs virtually no maintenance.
- Zero electricity for daytime lighting — the bill simply disappears
- No motors, no circuits: extremely low failure rate, long service life
- Even, glare-free diffused light improves the working environment
- Harvests daylight even on overcast days; pairs with lighting controls for top-up
