On January 27, 2026, the inauguration conference and celebratory dinner of Good Light Group Asia (GLGA) were successfully held at the Guangzhou East Railway Station Intercity Hotel.
More than 100 “Good Light partners” from across the industry — including LED chips, luminaires, drivers and controls, optics, lighting design, research, industry organizations, and media — gathered to witness the official opening of the “Good Light Wake-up Call” movement.
This was more than an event. It was a declaration of action for the entire value chain.
GLGA aims to establish a clear definition, foundation, and shared language for “good light”, enabling it to move from consensus to being measurable, verifiable, and deliverable, and ultimately to become a form of healthy light that can be reliably delivered over the long term.
A Shared Action Consensus: Good Light Comes Before Healthy Light
In the opening speech, Lawrence Lin, Founder of GLGA and Asia Director of GLG, shared a core judgment:
Healthy light is not about being brighter, more expensive, or bluer.
The key to healthy light is timing — delivering the right stimulus, in the right way, at the right time, and in the right context.
But all of this depends on one prerequisite: the foundation of good light must first be established.
Good light must be:
- Usable: clear and comfortable to see, supporting work and daily life
- Comfortable: non-glaring, low-glare, low-flicker, suitable for long-term viewing
- Authentic: color quality and gamut closer to daylight logic, allowing us to “see truthfully”
This is also GLGA’s core message: Good light first — then healthy light.
Appreciation and Encouragement: Strong Support from the Healthy Building and Design Community
The conference received valuable support, encouragement, and insights from two distinguished guests:
Mr. Zhang Weishun, Vice President of IWBI China
From the perspective of healthy buildings and WELL implementation, he emphasized the importance of being verifiable and implementable, encouraging the industry to adopt more auditable approaches to promote healthy lighting in real spaces and ensure long-term operation.
Professor Chang Zhigang, Vice Dean of the Academy of Arts & Design, Central Academy of Fine Arts
In his talk “The Future of Healthy Lighting”, he highlighted that the foundation of lighting aesthetics must be built upon health and comfort. Only when human experience is respected can “good light” truly be accepted and used sustainably over time.
From Concepts to Methods: Embedding Healthy Light into a “People + Space + Time + Activity” Model
Within the “Good Light Wake-up Call” framework, GLGA emphasizes that healthy light is not a single parameter, but a system-level delivery of people and spaces.
At the conference, Daniel Cheng, Secretary-General of GLGA, presented live measurement demonstrations, showing how light quality can be evaluated across luminaires, spaces, and human perspectives. He introduced a key framework for healthy light:
People + Space + Time + Activity
This framework focuses not on a single measurement value, but on exposure structure — what light people actually receive throughout the day, in different locations, and during different activities.
This explains why many spaces look bright, yet still cause fatigue, glare, and discomfort.
The issue is often not insufficient illuminance, but factors closer to real experience: contrast, glare, directionality, and flicker.
Certification and Partnerships: The First Group of “Good Light Partners” Sets Sail Together
During the launch and certification ceremony, GLGA awarded certificates to the first group of organizations and expert partners participating in the “Good Light Wake-up Call” initiative.
This recognition represents not only honor, but a shared commitment: to transform “good light” from a concept into reusable, deliverable, and verifiable practice standards.
At the same time, GLGA completed cooperation signings with several core partners and announced future collaboration with organizations such as Messe Frankfurt and IWBI. Together, they will promote a series of activities and industry collaborations centered on good light and healthy light, continuously advancing shared industry understanding and implementation.
Turning Up the Energy at the Dinner: Taking the Consensus Home
If the afternoon conference focused on building consensus, the evening banquet elevated engagement and participation. Interactive quiz sessions — including rapid Q&A, multiple-choice, and bonus questions — transformed key ideas from the day into a shared language that participants could remember, articulate, and explain clearly.
Encouragingly, many participants answered fluently.
As more people master the language of “good light,” awakening becomes more than a slogan — it becomes a clearer and more actionable path forward.
What’s Next: Making “Good Light” the Industry’s Common Foundation
The establishment of GLGA is not an endpoint — it is a beginning.
Moving forward, GLGA will focus on three priorities:
- Shared language: establishing a unified foundation and boundaries for “good light”
- Verifiable delivery: turning healthy light from marketing concepts into systems that are measurable, testable, and maintainable
- Real-world implementation: accumulating evidence and case studies through verifiable methods across offices, education, healthcare, commercial, and residential environments
Because we all know:
Everyone says they want to sell good lights and healthy lights.
But without caring about real user experience, it is impossible to truly build good products or a healthy market. And when an industry is trapped in price competition while ignoring long-term enterprise and industry health, how can we seriously talk about “healthy lighting”?
Closing
Sincere thanks to Sunray Technology, Zhuosheng Lighting, Insonna, Mukon Smart Lighting, and other partners for their strong support of this event.
Thank you to every participant who attended, shared encouragement, and invested time and resources.
Let’s take “good light” beyond internal industry discussions and into broader public awareness.
Good light first — then healthy light.
Good Light Wake-up Call starts now.
