Preserving history with AirGlow wireless lighting control

When tasked with modernizing lighting control at sites of historical significance, traditional wired systems are out of the question. That’s where LumenRadio’s wireless technology comes in.

Digimax, a LumenRadio partner in Italy, was approached by a customer about delivering advanced, programmable lighting to a centuries-old castle located in Viterbo in the Italian region of Lazio.

“The primary challenge was delivering a reliable lighting control system without altering or damaging the ancient architecture,” explains Nemanja Jovanovic, Product Manager at Digimax. “We needed a solution that would respect both the technological and cultural requirements of the space.”

Historic sites like these pose a unique challenge: due to strict heritage preservation regulations, it is not possible to install traditional wired infrastructure or mount external components that affect the site’s appearance or structure.

Adding to the complexity, the customer required advanced time-based lighting control. Lights needed to be programmed to switch on and off on specific days and during predefined time slots, tailored to operational requirements and to accentuate the castle’s impressive features during public or private events.

Wireless innovation with AirGlow

Digimax chose LumenRadio’s AirGlow – designed for wireless control of outdoor lighting – to overcome the physical restrictions posed by the project. The decision was based on LumenRadio’s ability to provide a robust and non-invasive solution that would preserve the integrity of the castle while delivering high-end functionality.

“With AirGlow we avoided any construction work as we didn’t need to run a single new DALI cable,” adds Nemanja. “The system has also left room for future scalability, allowing us to expand control to new areas as needed – without compromising the architectural integrity of the castle.”

Scalable control for a timeless landmark

The adoption of LumenRadio’s technology has delivered several tangible benefits for the customer, especially given the unique nature of the application environment.

“The ability to implement an advanced lighting control system at a historical site like this was crucial for preserving cultural heritage. At the same time, the speed of execution and reduced cost of installation – made possible by the wireless architecture – optimized project timeframes and the use of resources.”

In addition, the inherent scalability of AirGlow has allowed the customer to adjust lighting based on specific events and time schedules, dynamically enhancing the space.

“At a heritage site like this castle, lighting needs can evolve over time,” explains Nemanja. “For example, the need to illuminate new areas, enhance temporary exhibitions or integrate additional control features. AirGlow can adapt to such changing requirements without the constraints typical of a wired infrastructure.”

The project also benefited from excellent collaboration and support.

“Working with LumenRadio was a very positive experience,” Nemanja concludes. “The technical support team was always ready to help – they were fast, professional and available throughout the entire project.”

By turning to LumenRadio’s wireless technology, Digimax successfully implemented a non-intrusive, scalable lighting control solution that met all functional requirements – while leaving the architecture of the castle untouched and ready for the future.
