Designing a lighting control system for a sacred space can be challenging. This is especially true when every intervention must be sensitive and discreet yet functional for various types of worship services and events. This was precisely the situation at the Salesian Church in Žabovřesky, Brno.

Wireless control was the answer where cables were not an option

ValmaX Led Eco s.r.o. was looking for a solution for this unusual space, as traditional cabling was simply not an option. There is no space in the church for installing new electrical wiring; the building's historical character does not permit it.

For this reason, they needed a reliable partner who could implement modern lighting control while respecting the sacred space. At the same time, the installation had to be simple.

Technical curiosity: one unit made up of several parts

The main lighting element, a circular light, was slightly more technically demanding to install than usual. It consists of almost 30 DALI drivers, which had to be connected so that they behaved as one compact unit. The issue was not the complexity of the connection itself, but rather the fact that an unusually large number of separate components were used for one light.

Interestingly, a single controller can usually manage an entire lighting line in an industrial hall, but due to the size and design of this installation, one was not enough.

The installation process was physically demanding. First, the ValmaX LED Eco team secured the 30-kilogram canopy and suspension system. Then, they assembled the light from individual segments on the ground. The most challenging part? Lifting the 250-kilogram circular body to a height of 12 metres using a mobile platform. The entire process required coordination, precision, and trust among the installation team.

The complex installation included:

• Two main circular lights (8 m and 6 m in diameter, with 84 suspension points each)
• Wall lights
• Organ lighting
• Spotlights to illuminate the altar

Another requirement was control via a tablet with a floor plan of the space, which was one of our first projects to implement intuitive control via a floor plan.

Our solution: discreet technology for sacred spaces

We used eight SC Industry A controllers to wirelessly control all the DALI lights in the church.

Key benefits of our approach:

• Wireless control: no interference with the historic building
• Floor plan control: intuitive lighting management directly from the floor plan
• Flexible scenes: adaptable to different types of worship services
• Simple operation: a tablet instead of complex control panels

The result: light that respects the space

The result is uniform, glare-free light that is soft and does not disturb the architecture, but quietly accompanies it. The space is now designed very discreetly – light has become a dominant yet respectful feature.

Thanks to intelligent control, the lighting can be adapted to any occasion, whether that be an intimate prayer, a solemn worship service, or a musical performance. Staff can easily change lighting scenes according to current needs without having to understand complex technical details.

As our partner ValmaX says, 'Working in this space was not just a job for us – it was a joy and a responsibility.'

Spectoda in sacred spaces

This project showcases the flexibility of our ecosystem. Spectoda can operate sensitively even in the most challenging environments, combining respect for the space with modern functionality.

Features such as wireless control, intuitive operation and the ability to adjust the atmosphere precisely make our solution ideal for historic and sacred buildings.

The Salesian Church in Žabovřesky is proof that, when approached with discretion and respect, modern technology has its place in traditional buildings.

Do you need to install lighting in a historic or sacred building? Our wireless system enables modern light control without interfering with the original structure.
