KKDC Testing and Standards


With the on-going education in the marketplace and the gradual introduction and adoption of standards and associated testing, more designers and specifiers have a good understanding of the hidden factors involved in producing colour consistent, stable and durable LED products.
As a global company, selling a quality product in the most discerning markets, all our products undergo external testing by independent accredited authorities to quantify and substantiate their performance.
KKDC products are tested to the IES LM79 photometric standard by the UK’s only UKAS (ILAC) accredited, independent commercial laboratory currently doing so (LUX-TSI Ltd).
Certification and provision of data from LM79 testing by an internationally accredited laboratory is currently considered best practice worldwide for the testing of complete LED luminaires.
Through the European CE scheme, ETL and UL certification all KKDC products maintain the most internationally recognised safety standards, including specific local requirements such as PSE for Japanese market.
Our research and manufacturing processes also incorporate many electrical and photometric testing procedures both for individual components and finished luminaires. Chromaticity testing in production quality control; thermal shock and harsh environment testing of housings and electronics; and extended duration testing.
Our testing program ensures products will perform as designed throughout their lifetime – even in the most demanding environments.
We look to provide our own test data wherever it can add useful understanding for specifiers beyond that provided by independent testing.

  • Accredited independent photometric testing to IES LM79.

  • Global safety certification through CE, ETL and UL.

  • Comprehensive in-house testing by KKDC engineers through all stages of research, design and manufacture.

  • Rigorous five point quality control testing procedure integrated with automated SMD PCB production.

  • Extended duration and exhaustive thermal testing of finished products to verify stated product lifetimes and ambient temperature ranges in service.
