Hope at night: How art, light and civil courage sparked a debate about freedom and society

In the Protestant Church in Oberrahmede, architect and lighting expert Thomas Schielke spoke about art as a form of social resistance – from protest projections in Los Angeles to AI images from Iran. In the discussion that followed, it became clear what these global signs have to do with Lüdenscheid.

It is dark in the Protestant Church in Oberrahmede on this Friday evening. Not only outside. Dr Thomas Schielke begins his lecture by stating that night is not just a time of day, but a state of being. A metaphor for a time when news weighs heavier than hope, when freedom seems vulnerable and the question arises as to what remains when certainties fade. Schielke does not talk about bright lights that dazzle. He talks about the light that remains. About hope.

The church is well filled. People sit close together, as if this proximity were already a quiet response to the theme of the evening. Schielke, an architect and lighting expert, has been working at the interface of design, art and social change for years. His lecture is not a linear argument, but a journey through images, interventions, projections, quotations, books and political events. A slide show that is more essay than presentation, more cultural criticism than specialist lecture.

It begins with Picasso’s ‘Guernica’. In the midst of the chaos of this world view stands a child with a torch. No heroic light, no salvation, just a small flame. ‘Perhaps that is hope at night,’ says Schielke. It is a thought that carries the evening: hope does not end suffering, but it contradicts darkness.

From there, it leads to Caravaggio’s ‘The Calling of Saint Matthew,’ to that narrow beam of light that transforms an everyday space into a moment of decision. Here, art becomes a moral resonance chamber. Not as decoration, but as an imposition: would we be willing to stand up and step into the light?

Light as the opposite of darkness

What follows is an international journey through places where light becomes a political gesture. Under motorway bridges in Los Angeles, the artist collective VJayBomb projects the Statue of Liberty onto a bridge pier. It slowly sinks into the water, the torch remains lit. Not a monument, not an iconic place, but a ‘non-place’ made of concrete. It is precisely there that the symbol of freedom appears – vulnerable, close, human. The projection lasts only minutes, but it permanently changes the way we see this place.

In Madrid, citizens protest as holograms in front of parliament because real gatherings are prohibited. In Chile, the word ‘humanity’ is projected onto the façade of a high-rise building – and demonstratively erased by security forces, which only serves to spread the message even further. In Bochum, drones take to the skies and write political messages in the sky. Art, as Schielke shows, is not decoration here, but action. Not illustration, but intervention.

Time and again, it is about courage. Not heroic courage, but the quiet courage of arriving, of looking, of setting off, of standing firm, of telling new stories. Quotes from Luisa Neubauer, Maja Göpel, Daniel Schreiber, Hannah Arendt and Karl Popper are interwoven with the images. The lecture is dense, almost exuberant, but never arbitrary. It revolves around the question of where society draws the strength not to remain silent.

If we are not prepared to defend a tolerant social order against the attacks of intolerance, then the tolerant will be destroyed, and tolerance with them.

Karl Popper, philosopher

If you are neutral in situations of injustice, you have chosen the side of the oppressor. If an elephant puts its foot on a mouse’s tail and you say you are neutral, the mouse will not appreciate your neutrality.

Desmond Tutu, Archbishop

It becomes particularly poignant when Schielke discusses current AI-generated videos from Iran. People with lights in their hands walking through the streets at night. No leader, no stage, just many individuals walking side by side. The light does not come from above, but from their hands. In times of internet blackouts, the smartphone becomes not a means of communication, but a source of light. Hope without pathos, but with force.

Here, the evening shifts from aesthetic contemplation to political urgency. Schielke talks about disinformation, the power of social algorithms, authoritarian regimes and the need not to counter intolerance with false tolerance. Art becomes a seismograph of social tensions. And then he asks the crucial question: What does all this mean for Lüdenscheid?

From global panorama to local responsibility

In the second part of the evening, Schielke talks to Dominik Hass-Sommer, chairman of the cultural committee in Lüdenscheid, and Pastor Michael Siol. After the global perspective, the focus shifts to the local level. But the conversation does not feel like a break, but rather a continuation on a different level.

Hass-Sommer describes how much our perception of the world changes when we look at it through real encounters rather than social networks. Election campaigns, club work, light routes – everywhere he experiences optimism, commitment and community. ‘The reality is often very different,’ he says. Algorithms distort, encounters ground us.

Siol picks up on this idea. Hope arises where people treat each other kindly. At the same time, he warns that values need guidance that goes beyond majorities. ‘Many people with torches can also be a torchlight march,’ he says, pointing to the need for clear ethical guidelines.

What emerges here is not a political debate, but rather a reflection on how the church, politics and culture can work together to create spaces for resonance. Hass-Sommer talks about alliances against intolerance, democratic compromises and culture as a place of encounter. Siol recounts stories of community festivals, picnics at the fire station and children’s musicals – of hundreds of volunteers who create moments of light in everyday life.

On this evening, Lüdenscheid does not appear as a provincial town, but as a laboratory. As a place where small decisions determine whether the light will be passed on. The church proves to be not a backdrop, but an equal sounding board. The sacred place reinforces the effect of the images and thoughts without appropriating them. Here, there is no preaching, only reflection. No moralising, only questioning. In the end, there is no dramatic conclusion, but a quiet thought: hope at night is possible because it is carried. Not by individuals, but by many.

When the visitors leave the church, it is still dark outside. But the light from the windows accompanies them for a while. Perhaps that is the real point of this evening: that art, church and society are not separate spheres, but together guard those little flames that contradict the darkness.

Superlux symposium: From productivism to scenography Urban branding

Germany-based essayists for the SuperLux book, and leading European light artists and lighting industry publishers and advocates, debated recent developments in the smart light cities movement, at an English-language symposium hosted by the Faculty of Architecture at the Technical University of Munich (TUM) in 2016.

On a benign winter’s evening during the city’s Christmas celebrations, the faculty’s Acting Dean, Professor Hannelore Deubzer, welcomed speakers and delegates to its rooftop seminar centre, the Vorholzer Forum, then introduced Dr Thomas Schielke, a SuperLux essayist, light architecture columnist for ArchDaily, and a communications and education leader with ERCO, to conduct the presentations.

SuperLux essayists Schielke, Vesna Petresin, and the book’s editor, Davina Jackson, spoke about recent developments in urban light art. Another essayist, Peter Droege, clarified the beyond-urgent need to power cities only with renewable sources of energy, but noted that lighting amounted to only about two percent of the world’s total energy consumption.

ArchDaily: From Productivism to Scenography: The Relighting of Norman Foster’s Hongkong and Shanghai Bank

Lecture

Three decades ago the Hongkong and Shanghai Bank (HSBC) Headquarters by Norman Foster emerged onto the architectural seen as an exemplary product of industrial design. The open layout with its exposed steel structure generated a powerful corporate identity for the bank. But the restrained atmosphere of white architectural lighting and the lack of distinctive façade lighting has lost its attractiveness after sunset. Now the colorful and dynamic relighting presents a remarkable example of how an architectural icon has shifted from a productivist ideology towards a scenographic image.

Light for Brand Communication: When Lighting becomes Part of CI

All over the globe, brands are looking to achieve a striking visual appearance within the urban space. Local and international companies have started to link light planning for retail spaces with the CI for a holistic brand appearance. Media façades have therefore been turned into a fascinating tool for creating an architectural landmark on the nocturnal cityscape. At night, the brand stories are told by shining messages that range from the conventional light boxes and illuminated advertisements to dynamically lit architecture. The colourful and dynamic appearance of façades and stores inside will trigger a debate about the importance of LED for brand communication, the limits of architectural lighting for CI and the way sustainability impacts marketing strategies.

Keynote: Streetscapes at Night – Lighting between Identity, Transformation and Safety

Lighting is an essential element to perceive the environment at night. Diverse ideas like transformation and branding, safety requirements and technological progress have led to different nocturnal streetscapes. Street lighting has been widely installed with the argument to improve safety. With the emergence of powerful and adaptive headlights in the automotive industry and highly reflective textiles for pedestrians, the role and effectiveness of conventional street lighting is questionable. From a technological point of view, energy efficiency and low maintenance have dominated the public debate and contributed to the immense growth of LED lighting in cities, but additional developments have accelerated this trend. The miniaturization of the light source and sophisticated control technologies have paved the way for new applications. On the one hand, wearable textiles and gadgets allow pedestrians to communicate and present themselves as luminous objects in streets in a small scale. On the other hand, global and local brands have turned facades into dynamic displays to send corporate messages in a large scale. Political activists have recognised the nocturnal communication possibilities and started to use light for raising awareness regarding social and political issues. A comprehensive semiotic analysis provides the framework to identify lighting as a sign to communicate messages within the city at night. International permanent and temporary projects illustrate how the role of lighting has changed and will influence our streets in urban areas.

How Apple strives for the perfect sky and revives cities

Apple stores do not only reveal the evolution of Apple`s design, but also how the concept of daylight and lighting has changed over the last two decades. The stores have become highly successful and over the years Apple have expanded their number of retail locations worldwide. Renowned architecture offices such as Bohlin Cywinski Jackson and Foster + Partners have developed iconic store designs where daylight and lighting play a central role. The translucent Apple cube on Fifth Avenue in New York City opened in 2006, and has even become the 5th most photographed building in New York according to Cornell scientists. The Apple stores worldwide are used as case studies to analyse the lighting design with regard to the aesthetic quality and cultural context. A focus is set on three aspects and how they contribute to brand communication: daylight, interior lighting and exterior illumination. Hence, the lighting is not observed as a tool to enhance visibility, but from a semiotic point of view where light is interpreted as a sign between the brand and consumer.

Luminous walls: From stained glass windows via modernist wallwashing to pixelated planes

Luminous walls belong to the essential repertoire of qualitative lighting design. With light, spaces can be defined and reinterpreted. Illuminated walls allow us to provide orientation and to perceive the form and dimension of space. Further, their glow and play of brilliants could bestow a space with an impressing scenography. The lecture by Thomas Schielke at the Professional Lighting Design Convention in Madrid revealed a timeline to explain different lighting approaches: From backlit stained glass windows for spiritual enlightenment in the gothic period to modernist uniform wallwashing. Contemporary examples opened the view for pixelated colour changing planes based on LED and OLED technology. The talk with an overview of international projects covered lighting methods and techniques for luminous walls and their visual appearance for interior spaces. With a perception-orientated design perspective the architect could use vertical illuminance to create bright spaces and thereby also contribute to sustainable lighting solutions.
