"Integrity in the lighting industry isn't just about passing a test; it's about the long-term reliability of a supply chain. With an engineering background from Victoria University (Australia) and two decades of navigating international logistics, I founded GY to solve one specific problem: the lack of transparency in high-efficiency lighting.My role is to ensure that our technical innovations—led by my senior R&D colleagues—are always backed by rigorous EU regulatory alignment. I am here to guarantee that our partnership is built on solid data, legal security, and a shared dedication to energy transition."
