deLIGHTed Talks Asia at GILE 2026: From Good Light to Measurable Human Outcomes

During the Guangzhou International Lighting Exhibition (GILE 2026) , deLIGHTed Talks Asia brought together an exceptional group of scientists, clinicians, lighting designers, architects, manufacturers, building professionals and industry leaders. Their backgrounds differed, but they shared one ambition: to accelerate the transition from conventional lighting to Good Light that genuinely improves people's lives.

The central question throughout the event was straightforward:

How can Good Light move from promising concepts to measurable, verifiable and scalable solutions?

Across keynote presentations, panel discussions and Focus Group sessions, speakers explored topics ranging from circadian science and brain function to healthcare, senior living, healthy homes, integrative lighting, lighting design, building performance and owner value. Although the subjects varied, a common theme emerged. The lighting industry has reached a new stage in its development. Technical innovation alone is no longer enough. Future value will increasingly be created by improving sleep, wellbeing, health and the overall human experience inside buildings.

That transition also requires a different way of working. Good Light cannot be built on marketing claims alone. It requires scientific evidence, thoughtful design, practical implementation and objective verification. It calls for collaboration between science, medicine, lighting design, manufacturers, building owners and standards organisations. Only then can Good Light become a trusted and widely adopted part of healthy buildings.

The discussions during deLIGHTed Talks Asia demonstrated that this transition is already underway. Across disciplines there is growing agreement that lighting should no longer be evaluated only by energy use, efficiency or visual performance, but also by the value it creates for people and for society.

The programme featured presentations by leading international experts, including:

• Robert Lucas: Measuring and Manipulating Light to Support Healthy Rhythms

• Marijke Gordijn: Good Light, Rhythms, and Circadian Health

• Jan Denneman: A Wake-Up Call — From Illumination to Human Outcomes

• Kei Haraguchi / Nichia: Dynasolis™ — Moving Beyond LPW to Create New Value

• Anne Berends: SunLED Life Science: Near-Infrared Light and Wellbeing

• Jeff Miller: Beyond Aesthetics — How Designers Translate Science into Human Experience

• Kevan Shaw: Practical Aspects for Implementing Integrative Lighting

• Martin Klaasen / VLDC: Future Forum Debrief — Trends, Opportunities and Recommendations for Life Centric Lighting

• Amardeep Dugar: Lighting Design for Wellness — A Salutogenic Framework

• Oliver Stefani: Evening Light, Sleep, and Family Wellbeing

• Zhao Hongyi: Light in Healthcare — From Compliance Lighting to Clinical Environment Design

• Professor Yandan Lin: Healthy Homes — The Next Upgrade Beyond Smart and Aesthetic Lighting

• Zheng Hongcheng: No Verification, No True Healthy Light — A Scientific Interpretation Based on EEG

• Dr. Wei-Jye Lin: How Light Acts on the Brain — From Visual Circuits and Brain Clearance to Verifiable Application Value

• IWBI / WELL Perspective / Richard Wei-Shun Chang: From Wellness Story to Asset Value

Together, these presentations illustrate how rapidly the field is evolving and how Good Light is becoming a multidisciplinary movement. The challenge now is no longer understanding why Good Light matters, but how to implement it responsibly, verify its impact and deliver measurable value for people, buildings and society.
