LiGHT 25, the UK’s only trade show dedicated exclusively to high-end lighting specification, will return to the Business Design Centre, Islington, London, on 19–20 November 2025.
Following the success of LiGHT 24, which welcomed over 5,500 visitors, this year’s edition will feature an expanded programme of innovation, education, and networking opportunities. Key highlights for 2025 include the introduction of the Technical Zone, the return of the Associations Lounge, and a new large-scale immersive light art installation.
Launched for the first time at LiGHT 25, the Technical Zone will provide a dedicated showcase for brands at the forefront of urban lighting, commercial lighting, control systems, components and OEM, lamps and gear, and emergency lighting. With advanced controls, emergency systems, and components playing an increasingly important role in sustainable and human-centric design, the Technical Zone offers both exhibitors and visitors a vital platform to exchange expertise and explore the latest developments.
Supported by Studio Due, the Associations Lounge will once again act as a shared hub for leading industry bodies, including the LIA, ILP, SLL and the IALD. Located on the Gallery Level, the lounge will provide visitors and exhibitors with a comfortable environment away from the show floor, complete with complimentary refreshments, networking events, and a dedicated talks programme. It also offers the opportunity to learn more about association initiatives and membership.
Central to the educational element of the show programme is the CPD-accredited [d]arc thoughts talks series in collaboration with Lutron. Curated and moderated by editors of arc and [d]arc magazines alongside guest moderators, the two-day talks programme will bring together global experts to address themes ranging from sustainability and circularity to wellness, health, and the business of design. Topics are set to include dark skies, inclusive design, multi-sensory environments, data transparency, colour, health and wellbeing. Whether you’re interested in sustainability, technical innovation or the human experience of light, the programme aims to inspire fresh thinking, professional development and meaningful dialogue.
LiGHT 25 will also feature a major new light art installation. Following Frankie Boyle’s acclaimed Intra-Spectrum in 2024, this year sees Speirs Major Light Architecture partner with formalighting to present Re:Vision. Exploring the theme of colour perception across species, Re:Vision uses custom spectral profiles and reimagined Ishihara colour blindness test patterns to reveal the diversity of visual experience across the natural world. The installation invites visitors to step outside their own perceptual boundaries and reconsider how lighting design can respond to a richly biodiverse and interconnected planet.LiGHT isn’t just a trade show made up of rows of exhibitors. It’s a chance for designers, engineers, and architects to really immerse themselves in light, learn more about how light shapes the design industry, and make new connections through our varied features.
In addition to these new features, LiGHT 25 will bring together thousands of architects, interior designers, lighting designers, engineers, and specifiers, alongside hundreds of leading architectural and decorative lighting brands. Visitors can also take advantage of networking opportunities throughout the event, including a late-night drinks party, a networking brunch, and a dedicated co-working space.
LiGHT 25 is a must-visit event for anyone involved in lighting, architecture, interior design, engineering, and beyond. From late-night drinks on the show’s opening night to a networking lunch on day two, visitors will have valuable opportunities to network and connect with peers and industry leaders. With breakout workspaces for on-the-go creativity and productivity, LiGHT 25 offers both inspiration and practicality – the perfect mix for discovering new ideas, strengthening professional relationships, and staying at the forefront of the lighting industry.
