International Standards for Street Lighting

The DALI Alliance (DALI), the TALQ Consortium (TALQ), and the Zhaga Consortium (Zhaga) are collaborating to unify data streams for smart outdoor lighting systems. The partnership and joint technical work aims to increase interoperability between components and to allow loss-free communication across entire outdoor lighting networks (ODN).

Benefits for Cities and other Operators

Investing in smart outdoor infrastructure is a long term decision. Seen that these projects often involve public funding, purchasers need to make sure, that the selected solution is future-proof and avoids vendor-lock-in. The collaboration between DALI, TALQ, and Zhaga plays a key role in advancing a wide range of sustainability goals for cities and communities.

	Future-Readiness	Future-proof ecosystems Future-proof investments Supply chain longevity
	Security and Resilience	Smart asset management System security Resilient infrastructure
	Operational Efficiency	Serviceability Reduced operating costs Cost savings for maintenance
	Openness and Interoperability	Interoperable solutions No vendor lock-in Open system architecture
	Sustainability Benefits	Reduced energy consumption Enabling longer lifetime of lighting systems
