The science and art of lighting will be in the spotlight at this year’s Design Inn Symposium, with leading experts on hand to deliver a dedicated Masterclass on the subject.
Hosted by Liam Petrie-Allbutt, Founder and Managing Director of design-led lighting collective Studio All, this Masterclass will bring together a visionary interior design director, a world-class lighting design leader, a cutting-edge controls specialist, and an asset owner who invests in creating exceptional spaces.
“Beyond CRI, lux, and automation, we’ll explore how lighting delivers both design excellence and commercial ROI,” says Petrie-Allbutt.
Register for Design Inn Symposium, Tuesday May 6 at Hilton Adelaide.
The Masterclass will cover three essential principles of light science: CRI (Colour Rendering Index) and how it influences the visual clarity of spaces; CCT (Correlated Colour Temperature) and understanding colour correction; as well as Lux and Lumens, and their role in lighting performance and perception.
These lighting considerations will be explored across different environments including bars, restaurants and hotels.

Panellists will discuss the impact of climate on lighting design; the role of restaurant lighting in ambience, decorative lighting, food resolution, and overall feel; as well as the hotel experience from lobby to lift, corridors, and guest rooms, integrating lighting with interior design.
This session will also examine:
Bridging Light Science and Real-World Experience – Translating the science of light into practical applications during concept design and execution.
Understanding the Lifecycle of Lighting in Design – From conceptual ‘painting with light’ to final execution, and how specification deviations impact mood, feel, and experience.
Enhancing the Built Environment through Light – How lighting design elevates architecture and user experience while simplifying controls and achieving ESG objectives.
