The ultraviolet (UV) disinfection industry has reached a historic milestone. In May 2026, China’s new national standard, Ultraviolet Radiation Sources for Disinfection — Part 3: Excimer Ultraviolet Radiation Sources (GB/T 19258.3-2026), was officially released. Led by GMY Lighting Technology Co., Ltd., this pioneering standard will formally take effect on December 1, 2026, marking a significant leap forward for industry regulation and technological standardization.
For years, the excimer UV sector has grappled with technical fragmentation, inconsistent testing methodologies, and fluctuating product quality. The introduction of GB/T 19258.3-2026 directly fills this long-standing regulatory void. By establishing definitive guidelines for the scope, classification, nomenclature, technical specifications, testing protocols, and inspection frameworks of excimer UV sources—focusing primarily on the 222 nm wavelength—this standard creates an authoritative benchmark that promises to elevate the entire industry's quality thresholds.
The publication of this national standard not only reshapes the market landscape but also cements GMY’s position as a trusted pioneer in photonic and optical technology. With over two decades of deep-rooted R&D expertise, GMY has consistently pushed the boundaries of UV light source manufacturing.
By spearheading this regulatory framework, GMY demonstrates its commitment to transitioning the UV disinfection sector from rapid, unguided growth into a new era of standardized, quality-driven development.
As a market leader, GMY has successfully achieved commercial-scale production of advanced excimer UV radiation sources, focusing on two highly specialized wavelengths to serve both high-end industrial manufacturing and public health sectors.
Engineered for highly demanding industrial environments, GMY's 172 nm excimer lamps provide stable and high-intensity vacuum UV (VUV) radiation. They are widely utilized in precision workflows, including:
Targeting human-centric environments, GMY's 222 nm excimer lamps offer an efficient and revolutionary approach to pathogen control. Because 222 nm light does not penetrate the dead layer of human skin or eyes, it provides a safe, continuous sanitization solution for high-traffic public spaces, such as:
