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, LiGHT25 once again welcomed thousands of visitors to the Business Design Centre in London. Over two days, the 19th and 20th of November, the exhibition centre was transformed into a creative and collaborative hub.

A record number of 6,764 attendees 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.

A key part of LiGHT’s success is that the exhibition is constantly evolving to attract new audiences in the sector and provide a unique offering. Launched for the first time at LiGHT25, the Technical Zone provided a dedicated showcase for brands at the forefront of urban lighting, commercial lighting, control systems, components and OEM, lamps and gear, and emergency lighting, giving visitors a vital platform to exchange expertise and explore the latest developments.

In the Decorative Zone this year, a special VIP Design Tour saw 23 leading interior design studios 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.

This year’s show featured an expanded programme of innovation, education, and networking opportunities. 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 Out of Our Lane: What Lighting Designers Must Learn from Medicine, with speaker Willie Duggan (Lighting Designer), which calls on lighting professionals to step beyond the silo of the industry. 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 said: “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 added: “We are so pleased with the feedback to this year’s show. The entire team had an amazing time exploring the new Technical Zone, 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.”

Free to attend, dates for next year’s show are now confirmed as the 18th and 19th of November 2026.
