German company Lanthan Safe Sky has relaunched under a new name, NOLITE, with effect from 15 July 2026. The Walldorf-based firm develops demand-based night-time obstruction lighting for wind turbines and other aviation obstacles – a technology that keeps warning lights switched off until an aircraft approaches.
The change is more than a new logo. It brings the company’s technology, operations and services together under a single identity. NOLITE was the first certified manufacturer of transponder-based demand-controlled night marking, known in Germany as BNK, and says it played a central role in developing the technology.
The company groups its offering into three product lines. NOLITE ADLS provides demand-based night marking as a managed service, covering planning, system architecture, certification, installation, monitoring and ongoing operation. NOLITE Offshore is aimed at projects with higher requirements for control, safety and autonomous operation. NOLITE OEM products allow third parties to integrate the BNK technology into their own systems for the first time.
The relaunch comes with a change in management. NOLITE will be led by Marc Förderer (CEO), Joachim Fetzer (CFO), Tobias Fetzer (CTO), Christian Hammer (COO) and Johannes Garrecht. Henning von Barsewisch, who built the company since its founding, is handing over operational responsibility and will remain involved in an advisory capacity. Alongside the rebrand, the company said it is moving to bring the BNK technology fully in-house, down to chip level, which it says would make it the first BNK provider to own its technology outright.
Demand-based night marking is increasingly required across German, Baltic and North Sea wind markets, where it reduces the visual impact of turbine warning lights on nearby communities while maintaining aviation safety.
