Good Light Group Asia (GLGA) is a regional platform dedicated to advancing healthy lighting and human-centric light environments across Asia.

As people spend more than 90% of their time indoors, the quality of indoor light has become a critical factor influencing health, wellbeing, and human performance. Yet most lighting systems are still designed primarily around energy efficiency and visual brightness, rather than biological and experiential needs.

GLGA was established to help bridge this gap.

Our Mission

With scientific research, international collaboration, and public education at its core, GLGA advances the adoption and implementation of “Healthy Light” (Good Light) across Asian societies.

Our Vision

To become Asia’s most influential:

• Healthy light science platform,
• International collaboration hub, and
• Standards and research center,

and to promote light science that improves sleep, mood, cognition, and quality of life.

GLGA Positioning and Core Values
