(UK) – The highly anticipated LiGHT Expo London returned for its fourth consecutive and increasingly successful year. As the UK’s only dedicated high-end lighting exhibition, LiGHT 25 once again welcomed thousands of visitors to the Business Design Centre in London. Over two days, the 19th and 20th November, the exhibition centre was transformed into a creative and collaborative hub.

A record number of more than 6,700 visitors braved the cold weather to attend this year’s show, demonstrating their unwavering support. LiGHT 25 brought together thousands of architects, interior designers, lighting designers, engineers, and specifiers, alongside hundreds of leading architectural and decorative lighting brands. Visitors attended inspiring talks and presentations from over 60 speakers, all while making new industry connections through creatively curated networking opportunities.

This year’s Decorative Zone proved one of the most talked-about elements, welcoming many new big-name brands to the zone, such as Italamp, Industville, Vibia and Lumen Loom. A special VIP Design Tour welcomed 23 leading interior design studios to participate in a whistle-stop guided tour of the show. The design professionals were treated to introductions to 10 leading lighting brands suited to the interiors market, before heading to the lounge for further networking opportunities. The tour received high-praise from both attendees and the participating brands for providing a concise yet informative platform to explore the show and make connections.

Always evolving in order to remain relevant to the wider industry, LiGHT 25 also introduced its new Technical Zone. While focused on brands in urban and commercial lighting, controls, components and emergency lighting, this addition sat alongside the decorative offering to ensure a well-rounded visitor experience.

Education and community were once again central to the event. Supported by Studio Due, the Associations Lounge once again acted as a shared base for leading industry bodies, including the DALI Alliance, The LIA, ILP, SLL and the IALD. Located on the Gallery Level, the lounge hosted networking events such as the in-person Silhouette Awards celebration, the LiGHT Lunch with Studio Due and speaker David Atkinson of DALD, and a dedicated two-day splinter talks programme.

Central to the educational element of the show programme were the CPD-accredited [d]arc thoughts talks series in collaboration with Lutron. Curated and moderated by editors of arc and darc magazines alongside guest moderators, the two-day talks programme brought together global experts to address themes ranging from sustainability and circularity to wellness, health, and the business of design. Topics and highlights include Shaping Atmospheres with Judith Patiño, of Vibia, who discussed how light and space work in unison to craft memorable spaces. Plus, True Luxury is Handmade: Crafted for Connoisseurs of Light, with speaker Surbhi Jindal (Da Light Hub / Women in Lighting India Ambassador), exploring the creativity that brings bespoke lighting designs to life.

Also new for 2025, visitors were able to immerse themselves in an innovative light art installation by Speirs Major Light Architecture in partnership with formalighting. Re:Vision explored the theme of colour perception across species, using custom spectral profiles and reimagined Ishihara colour blindness test patterns to reveal the diversity of visual experience across the natural world.

Managing Director, Paul James comments: “We are once again blown away with the positive response and overwhelming attendance to the show. We are proud that the exhibition keeps getting bigger and better this year, cementing LiGHT as a must-visit event for anyone involved in lighting, architecture, interior design, engineering, and beyond. The show has a perfect mix to discover new ideas, strengthen professional relationships, and stay at the forefront of the lighting industry.”

Helen Ankers, [d]arc thoughts Programme Director adds: “We are so pleased with the feedback to this year’s show. The entire team had an amazing time exploring the zones, attending the range of inspiring talks from renowned speakers across the industry, and being in awe of the light art installation from Speirs Major. Thank you to all the media partners, event supporters and exhibitors for your valuable contributions this year. We hope that LiGHT will continue to be a success for years to come, and we are looking forward to sharing special plans for our milestone fifth year in 2026.”

LiGHT remains free to attend, with next year’s dates confirmed for 18–19 November 2026.
