LiGHT 25 in London is set to bring together contractors, designers, specifiers, and architects to explore developments in lighting design, technology, and collaboration across the industry.
Organisers say the event will feature more than 200 exhibitors, a programme of talks, and networking areas designed to encourage discussion around the role of light in the built environment.
A new light installation
Following the ‘Intra-Spectrum’ installation by artist Frankie Boyle at last year’s show, LiGHT 25 will feature a new light art centrepiece titled ‘Re:Vision’.
The work is a collaboration between Speirs Major Light Architecture and formalighting, and is described as an “immersive exploration of light and perception.”
According to the designers, Re:Vision examines how different species perceive colour and light using custom spectral profiles and adapted Ishihara colour blindness patterns.
The installation is intended to prompt reflection on how artificial light influences both human and non-human experience.
Speirs Major says, “We’ve always been fascinated by how each species experiences a completely different version of reality, despite sharing the same planet.
“When you begin to understand this, you start to think about the impact we as lighting designers have on those experiences through artificial light.
“This installation is intended to open minds – to start a conversation about designing not just for humans, but for the many other living beings that share our spaces.”
The company explains that the work translates scientific research into a physical experience by creating environments inspired by the visual systems of various animals.
Within these areas, visitors encounter colour charts that appear or disappear depending on the light spectrum.
“It’s not about simulating another species’ vision, but about creating a spark, an opportunity to see differently, even for a moment,” continues Speirs Major.
Formalighting’s lighting systems are said to play a central role in enabling the dynamic light shifts within the installation.
“Formalighting have been fantastic collaborators,” Speirs Major notes. “Their technology allowed us to experiment and deliver light in new ways, pushing beyond traditional boundaries.”
The project draws inspiration from philosopher Thomas Nagel’s essay, What Is It Like to Be a Bat?, which questions the limits of human perception.
“Humans are the only species that truly needs artificial light,” the company continues. “Yet our use of light affects every other species.
“Birds stay awake longer under urban lighting, nocturnal creatures lose darkness, and ecosystems are disrupted. This project asks us to think beyond ourselves.”
According to Speirs Major, Re:Vision also connects to wider discussions about accessibility in design, stating, “Even within our own species, perception varies; ageing changes how we see, and those with colour blindness experience the world differently.
“Re:Vision is a reminder that design must account for those differences, cultivating awareness and empathy along the way.”
LiGHT 25 organisers say the installation will serve as one of the show’s key artistic features, aiming to encourage dialogue around the role of lighting in architecture and the environment.
