Studio Waldemeyer presents candlelit installation and jazz concert at St Stephen Walbrook during London Design Festival

London-based interdisciplinary design practice Studio Waldemeyer unveils Lumeable, its new range of rechargeable candlelights, with an atmospheric installation and charity concert at the historic church St Stephen Walbrook on Tuesday 15th September 2026.

Created to raise funds for the care and maintenance of Sir Christopher Wren’s landmark church, Studio Waldemeyer’s installation will surround Henry Moore’s celebrated altar with hundreds of Lumeable candles, demonstrating the new range’s versatility and highly visual impact.

For one evening, Studio Waldemeyer will transform the church into an immersive landscape of warm, flickering light. Lumeable candles arranged on and around Moore’s circular travertine altar will rise at varying heights, creating a luminous constellation at the centre of Wren’s carefully proportioned interior. Light, music and architecture will come together in a contemplative candlelit experience.

Lumeable is the result of more than 15 years of artistic and engineering research by Studio Waldemeyer into the emotional qualities of candlelight. Through bespoke electronics and a custom light algorithm informed by observations of natural fire, the range recreates the movement, warmth and atmosphere of a real flame.

Each rechargeable candle combines a sculptural, hand-formed glass vessel with Studio Waldemeyer’s patented electronic flame technology. The light moves with the subtle variation and unpredictability of fire, while providing a reusable, flameless alternative for domestic, hospitality and cultural settings. The candles offer different brightness levels,  replaceable batteries, and have been designed for ease of repair and long-term use.  

The installation continues Studio Waldemeyer’s relationship with St Stephen Walbrook, following Halo, an illuminated pendulum presented above Moore’s altar during London Design Festival 2023. The 2026 Lumeable installation brings together hundreds of individual points of light in a collective glow, reflecting the church’s enduring role as a place of gathering, contemplation and hope.

The project places Lumeable within one of Wren’s most celebrated interiors. Rebuilt after the Great Fire of London and completed in the late 17th century, St Stephen Walbrook is renowned for its pioneering dome and is widely regarded as an architectural precursor to St Paul’s Cathedral. Henry Moore’s altar, introduced as part of a major 20th-century reordering of the church, provides a powerful modern focal point within the historic space.

“Returning to St Stephen Walbrook after ‘Halo’ feels both personal and significant,” says Moritz Waldemeyer, Co-Founder of Studio Waldemeyer. “The church is an extraordinary meeting of geometry, history and spiritual atmosphere. This time, hundreds of small candle flames will come together around Henry Moore’s altar, transforming individual candlelight into a shared experience.”

For Co-Founder Nazanin Farahbod, the project connects the symbolism of candlelight with a practical act of care.

“A candle is one of the simplest and most universal expressions of hope, remembrance and human connection,” says Farahbod. “Filling this remarkable church with candlelight, music and people, and at the same time helping to support its future, gives the installation a meaning that extends beyond the objects themselves.”

Presented as a charitable collaboration between Studio Waldemeyer and St Stephen Walbrook, proceeds from the concert will support the ongoing care and maintenance of the Grade I-listed church.

The event takes place during London Design Festival 2026, which runs across the capital from 12th – 20th September.
