For millennia, we have known that glass is a durable material. It can resist corrosive substances and harsh environments. In the early 20th century, stainless steel appeared as a material with much better corrosion resistance. It soon helped many industries, including architecture and medicine.
Engineering a Solution for Extreme Tunnel Conditions
When we began designing a luminaire for London Underground tunnels, we needed materials that could handle a very harsh environment. Moisture in the network contains corrosive substances, so choosing the right materials was vital.
Centinox: A 100‑Year Design Life Luminaire
Centinox is made from marine‑grade 316L stainless steel, including all external hinges, latches and fixings. The body uses full seam welding. These features work with our replaceable double‑gasketing system and coated glass screen to create a luminaire suited to this demanding environment.
The geartrays allow upgrades at any time. They use plug‑and‑socket connectors and need no tools. Because of this, we believe Centinox is Designplan’s first product with a 100‑year life. It is a true 100‑year design life luminaire.
Designed for Reliable, Low‑Maintenance Operation
Centinox supports simple maintenance and upgrades. In places where access is limited, such as sub‑surface rail tunnels, keeping lighting safe and reliable is the main priority.
We designed the optical performance specifically for these environments. The solution provides the right amount of light for many tunnel types across complex rail networks. As a result, Centinox stands ahead of anything currently available. It delivers durable lighting and long‑life performance.
Built for the London Underground — Ready for Rail Networks Worldwide
Centinox offers long life, low maintenance and strong reliability. Because of this, it is an ideal choice for sub‑surface rail tunnels worldwide. Built for the challenges of the London Underground, Centinox‘s long life, minimal maintenance and total reliability make it the ideal choice for sub‑surface rail tunnels worldwide.
Ultimately, Centinox sets a benchmark in resilient and sustainable tunnel lighting. It remains a 100‑year design life luminaire built for the most demanding environments.
