Zhaga Consortium Testing & Certification

Zhaga Consortium certification

Zhaga is an international, industry-wide consortium for the standardization of LED lights, with specifications aimed at ensuring the interchangeability of LED light sources from different manufacturers. At present, many lighting companies make their own mutually incompatible LED modules. This lack of interchangeability in light sources drives up R&D costs as light sources need to be upgraded and various lighting parameters such as color, temperature, light output and beam angle need to be constantly changed. Zhaga certification indicates that a lighting company’s products are standardized and follow Zhaga recommendations.

There are numerous benefits:

• Simplify repairs, refurbishment and upgrades
• Become future-proofed for large industrial customers and municipalities
• Boost buyer trust and preference for your brand
• Avoid over-production of lighting which soon becomes obsolete
• Increase volume of sales for standardized products

TÜV SÜD helps you become Zhaga certified

TÜV SÜD is a fully recognized and accredited Zhaga testing laboratory that performs various compatibility, thermal, electrical and photometric tests and certifications. We also perform safety, EMC, energy efficiency and chemical tests for your LED products. We have a global network of multidisciplinary experts and our laboratories are equipped with the latest optical testing systems. Our certifications are backed up by long-standing accreditations in key markets.

We conduct a comprehensive range of tests which help demonstrate that your product is Zhaga certified:

• Interchangeability – we test and certify LED luminaires and LED light engines according to Zhaga specifications. These specifications enable the interchangeability of LED light sources made by different manufacturers.
• Photometric interface – we conduct photometric tests concerning the parameters of the light-emitting surfaces: their dimensions, position and orientation, as well as the LED light engine’s luminous output, luminous intensity distribution and luminance uniformity. Other important parameters tested are the beam angle and correlated color temperature.
• Mechanical interface – mechanical interface testing checks the correct dimensions, positioning of contacts, coded keys and fixing methods of the light engine and holder.
• Failure analysis – in addition to yielding comprehensive and in-depth analyses, our independent investigations can reveal root causes of failures. These analyses lead to solution proposals for preventative measures to avoid product failures that might result in hefty disputes and compensations.
