Good Light Asia Alliance (GLGA) Officially Established

On January 27, 2026, the launch conference and celebratory dinner of the Good Light Asia Alliance (GLGA) were successfully held at the Jiahong Hall of the Guangzhou East Railway Station Intercity Hotel. Over 100 "Good Light Companions" from LED chips, luminaires, driver control, optics, lighting design, scientific research, industry organizations, and media gathered together to jointly witness the official opening of the curtain on "Good Light Awakening."

This is not just an event, but a declaration of action directed at the entire industry chain:

We aim to establish the definition, foundation, and common language of "Good Light," enabling "Good Light" to evolve from consensus into something measurable, verifiable, and implementable, and further transform "Good Light" into healthy light that can be truly delivered over the long term.

A consensus for action: Good light first, then healthy light

In my address at the Conference, I shared a core judgment:

Healthy light is not “brighter,” nor “more expensive” or “bluer.” The key to healthy light is “timeliness”—providing the right stimulation at the right time, in the right scenario, and in the right way.

And the prerequisite for all of this is that the foundation of “good light” must be established first:

Usable: clear visibility, comfortable viewing, supporting work and life
Comfort: Non-glaring, low glare, low flicker, allowing for "prolonged viewing"
Authenticity: Color quality and gamut closer to daylight logic, allowing for "true viewing"

This is also the core slogan of GLGA: Good light first, then healthy light.

Acknowledgments and Encouragement: Strong support from the healthy building and design academia

The conference specially thanks two important guests for their support, encouragement, and reminders for "Good Light Awakening" on site:

Mr. Zhang Weishun, Vice President of IWBI China: Starting from healthy buildings and WELL implementation pathways, he emphasized the importance of being "verifiable and implementable," encouraging the industry to promote the adoption and continuous operation and maintenance of healthy lighting in real spaces through more verifiable methods.

Dean Chang Zhigang, Deputy Director of the Art and Design Research Institute of the Central Academy of Fine Arts, Professor, and Doctoral Supervisor: In his presentation titled "The Future of Healthy Lighting," he pointed out from the perspective of design and human-factor experience that the foundation of lighting aesthetics should be built on health and comfort; only when "feelings" are respected can "good light" be truly accepted and used long-term.

From concept to method: Integrating healthy lighting into the "People + Space + Time + Activity" model

Within the "Good Light Awakening" action framework, GLGA emphasizes: Healthy lighting is not a single-point parameter, but a systematic delivery for spaces and populations.

At the conference, Cheng Yu, Secretary-General of GLGA, provided a measurement demonstration, showing how to assess light quality across different dimensions of luminaires, spaces, and people, and proposed key structures to consider for healthy lighting:

People + Space + Time + Activity

It corresponds not to "a single measurement value," but to an exposure structure: what light environment people actually receive throughout the day, in different locations and during different activities.

这也解释了为什么很多空间“看起来亮”，却依然让人疲惫、刺眼、难受——问题常常不在“照度不够”，而在对比、眩光、方向性与闪烁等更贴近真实体验的因素。

Certification and Signing: The First Batch of "Good Light Companions" Sets Sail Together

During the launch ceremony and certification session, we awarded certificates to the first batch of organizations and expert partners participating in the "Good Light Awakening Action"—this is not only an honor, but also a shared commitment:

Together, we turn "good light" from a concept into practical standards that are reusable, deliverable, and verifiable.

Meanwhile, cooperation agreements were signed with multiple core partners at the Conference, and it was announced that GLGA will jointly launch a series of activities and industry collaborations centered on "good light and healthy light" with partners such as Messe Frankfurt and IWBI, continuously promoting the formation and implementation of industry consensus.

The gala dinner raised the "decibels": taking consensus home through prize-winning Q&A.

If the afternoon Conference was about "building consensus," then the gala dinner elevated the emotional value and sense of participation even further.

Three rounds of interactive games with prizes—rapid-fire Q&A, multiple-choice questions, and bonus questions (30-second stage expressions)—transformed the day's core concepts into a common language that everyone can "remember, articulate, and explain clearly."

Even more gratifying was that many guests on site answered fluently:

When the language of “good light” begins to be mastered by more people, awakening is no longer just a slogan, but an increasingly clear path to action.

Our next step: make “good light” the common foundation of the industry

The establishment of GLGA is not the end, but the beginning. Next, we will continue to advance three initiatives:

Common language: give “good light” a unified foundation and boundaries
Verifiable Delivery: Transforming healthy lighting from a "marketing concept" into a system capability that is measurable, verifiable, and maintainable
Real-world Implementation: Accumulating evidence and cases through verifiable methods in scenarios such as offices, education, healthcare, commerce, and homes

Because we all know:

We all say we want to sell good lights and healthy lights, but if we don't care about users' real experiences, we cannot truly make good products or succeed in the market.

And when the industry is left with only price wars, ignoring the long-term health of enterprises and the industry, on what basis can we talk about "healthy lighting"?

Conclusion

Thank you to everyone who came in person, everyone who sent their blessings, and every companion willing to invest time and resources.

Let us together bring “good light” from internal industry discussions into broader public awareness—

First comes good light, then healthy light. The awakening to good light starts now.
