As lighting products become increasingly diverse and widespread—from household shrine lamps to large-scale public tunnel lighting—the demand for product quality and safety continues to rise. JHEt’s laboratory is equipped with comprehensive and advanced testing instruments, including integrating spheres, goniophotometric systems, light flicker meters, and photobiological safety analyzers. We provide complete lighting performance and safety testing services in compliance with international standards and tailored to our clients’ specific needs.

We not only perform testing but also assist clients in understanding the technical requirements and procedures necessary for product certifications such as CNS, EN, and IEC. JHEt provides professional consultation and technical support to help accelerate product launch timelines and ensure full regulatory compliance.
