LiGHT 25, the UK’s only trade show dedicated to high-end lighting specification, returns to the Business Design Centre, Islington, London, on 19–20 November 2025, bringing two days of innovation, creativity, and connection for the design community.
For interior designers, the show is more than an exhibition – it’s an immersive experience that reveals how light can transform spaces, shape atmosphere, and elevate every detail of a project. Building on the success of last year’s event, which welcomed over 5,500 visitors, LiGHT 25 introduces exciting new features designed to spark fresh ideas and open new conversations.
A large-scale immersive light art installation will be at the heart of the show, offering visitors the chance to experience light as an artistic medium and a tool for storytelling. Alongside this, the brand-new Technical Zone will showcase the latest in control systems, emergency lighting, lamps and gear, components, and OEM solutions, giving designers a first look at the technologies that are quietly driving sustainable and human-centric interiors.
The Associations Lounge, supported by Studio Due, will once again provide a space for visitors to connect with leading industry bodies, enjoy complimentary refreshments, and be immersed in a separate curated splinter talks programme – it’s a space that encourages conversation and collaboration in a more relaxed setting.
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 industry experts to address hot topics. 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. For designers, it’s an opportunity to expand knowledge, gain new perspectives, and engage with some of the most relevant themes shaping the future of the profession.
LiGHT 25 is about more than browsing products – it’s a chance to immerse yourself in light, explore how it connects with design in every sense, and meet the people shaping the industry. From late-night drinks on opening night to a relaxed networking brunch on day two, the event creates natural opportunities for designers to connect with peers, suppliers, and collaborators, all while discovering the very latest in architectural and decorative lighting.
For interior designers who want to stay inspired, informed, and connected, LiGHT 25 is the place to be this November.
