Founded in October 2004 and headquartered in Taoyuan City, Taiwan, the company operates as a key member of Ennostar Inc., having joined the group in 2021. In February 2025, Ennostar announced a strategic acquisition to increase its ownership in ProLight Opto from 53.69% to 100% through a tender offer at NT$9 per share, aiming to enhance value-driven applications in automotive lighting, advanced displays, intelligent sensing, professional lighting, and optical communications under its "3+1" development strategy; this move supports potential privatization and delisting from OTC trading. The acquisition leverages ProLight Opto's compound semiconductor expertise to deepen group synergies in LED packaging for high-growth markets.
