KEY TAKEAWAYS
- Zhaga announced the first Book 26 certified products
- Book 26 covers linear socketable LED interfaces
- Serviceable modules can reduce full-luminaire replacement
- Certification does not replace performance evaluation
- Long-term compatible module availability remains important
01The Certification Milestone
On 13 April 2026, the Zhaga Consortium announced the first certified products under Zhaga Book 26 for linear socketable LED modules in non-SELV applications.
According to Zhaga, BJB certified a connector and LEDVANCE certified a luminaire.
02What Book 26 Addresses
Zhaga Book 26 defines an interface for linear socketable LED modules used in higher-voltage applications.
A standardized mechanical and electrical interface can allow compatible components from different suppliers to work together.
Key Industry Implications
01 What Book 26 Addresses
Zhaga Book 26 defines an interface for linear socketable LED modules used in higher-voltage applications.
02 Why Serviceability Matters
Traditional integrated LED products can be difficult to repair when the light source or connection system fails. Socketable modules can support component replacement without discarding the entire luminaire.
03 What Specifiers Should Verify
Certification applies to defined interfaces and products, so specifiers still need to review performance, safety, thermal management, optical quality and local compliance.
04 Industry Significance
The first certifications move Book 26 from an interface specification toward a commercial ecosystem.
03Why Serviceability Matters
Traditional integrated LED products can be difficult to repair when the light source or connection system fails. Socketable modules can support component replacement without discarding the entire luminaire.
This approach aligns with circular-economy goals and may extend useful product life.
04What Specifiers Should Verify
Certification applies to defined interfaces and products, so specifiers still need to review performance, safety, thermal management, optical quality and local compliance.
They should also confirm the availability of compatible replacement modules over the expected project life.
