Tethered Lighting System
TLS by Sirius Radius
The idea for this product began nearly a decade ago, when its original inventor — a humble yet exceptionally skilled engineer and successful entrepreneur — had a simple but revolutionary thought: “With camera drones becoming so popular, why not try something different? What if a drone could carry an energy-efficient yet incredibly bright light — one that could stay airborne for hours, cover vast areas, turn night into day, withstand harsh weather, and provide illumination for farms, construction sites, or rescue missions?”
It sounded simple, but creating a compact, reliable, weatherproof, and truly efficient lighting drone proved far more challenging than attaching a camera. Imagine a one-kilogram flying light competing with industrial lighting systems weighing hundreds of kilograms — or even a ton. It seemed almost impossible. Yet that idea inspired years of determined research, design, and testing. Sirius Radius joined the project early on, helping refine the design and develop new variations, hoping this technology could benefit communities across the southern hemisphere — especially in the Oceania region.
The result is a breakthrough innovation: a portable “Tethered Lighting System” — a small aerial light powered from the ground via AC supply. Compact enough for one person to carry and deploy, it can lift a powerful light into the sky anywhere, anytime. With just a small generator and a few litres of fuel, it can illuminate large outdoor areas all night long — creating a scene almost cinematic, as if drawn from science fiction. The photos below show real operations. Though most were taken on mobile phones with limited image quality, they offer a genuine glimpse into the system’s real impact — from water rescues and chemical plant emergencies to disaster relief and night-time construction. The system has also supported temporary hospital builds during the COVID-19 pandemic and assisted rescue missions after the Turkey–Syria earthquake in 2023 and the Myanmar–Thailand earthquake in 2025.
At a time of increasing climate instability and ongoing conflicts, we hope to connect with all who share our belief in innovation as a force for good — a light that strengthens and sustains humanity. Together, we can make Australia — and the wider Pacific region — a safer, brighter, and more resilient place for all.
May the light be with you.
Three Lamps, One Brilliance
We currently offer three straightforward models, each with different brightness levels, weights, sizes, and tether lengths — designed to suit a range of users and needs.
As we work directly and closely with our production lines and engineers, these machines can be custom-built upon request. Our standard-spec models are available in Sydney for on-site demonstrations — please feel free to contact us.
Please note: as these products continue to evolve through collective innovation and feedback, their design details may change over time. For the most up-to-date specifications and appearance, please contact us by email or via the enquiry form at the bottom of this page.
