On-Site Testing Services(Field Measurement)
JHEt provides on-site measurement and testing services for installed lighting systems to verify whether the actual illuminance distribution in the operating environment complies with design specifications, technical standards, and regulatory requirements. This service is applicable to public infrastructure, commercial spaces, industrial facilities, and medical institutions, serving as both a basis for project acceptance and a reference for design adjustment. All testing is performed on-site by professional engineers using high-precision measurement instruments, and detailed test reports are issued to assist owners and supervisors in completing acceptance procedures, ensuring lighting quality and compliance.

Reference Cases
- Science Park Smart Streetlight Energy Efficiency Acceptance Testing: Commissioned by a public works project in a science park, JHEt conducted on-site testing of newly installed smart streetlight systems to ensure compliance with government energy-saving subsidy and project acceptance requirements. Field services included illuminance measurement, luminous efficacy evaluation, color temperature, and color rendering testing, in accordance with CNS 15630 and Energy Label technical specifications. The final results confirmed that all luminaires met energy efficiency standards, featuring stable light distribution and low-glare design. The comprehensive test report supported the client in project acceptance and subsidy application, effectively improving lighting quality and energy performance.
- Public Library Indoor Lighting Illuminance Acceptance Testing: JHEt conducted on-site illuminance testing for a public library’s indoor lighting system, following CNS 12112, CNS 5065, and building design standards. Measurements were taken in reading rooms, book stacks, corridors, and offices to verify compliance with minimum illuminance requirements (e.g., ≥ 500 lux for reading areas). All results were compiled into a detailed test report, serving as technical documentation for construction acceptance and supervision review.
