Building Power Distribution and Lighting Energy Efficiency Testing
The building power distribution and lighting energy efficiency test system comprises the IMS-2021 spectroradiometer integrating sphere, GMS-2020 goniophotometer and building lighting test software. It measures initial luminous efficacy, ballast efficacy, light distribution curves, luminaire efficiency, power, power factor, harmonic content and colorimetric parameters (CCT, CRI) for power distribution and lighting energy efficiency projects, supporting WELL Building Standard V2 certification with key lighting parameters such as efficacy, UGR, CCT and CRI. Compliant with GB 50034-2024, GB 17625.1-2022, GB 7000.1-2023, GB/T 24825-2022, GB55016-2021, WELL Building Standard V2, IES LM-79-24 and related standards.
