Enterprise News | A New Benchmark for Domestic Far-UVC Export: 160 Sets of Filter-Free 222nm Excimer Lamps Exported to Germany
(SHENZHEN, May 2026) – Recently, Excimerlight, the premium deep ultraviolet (DUV) light source brand under Shenzhen LightS Technology, has officially completed production and rigorous quality inspection for 160 units of self-developed 6W filter-free 222nm KrCl excimer lamps, which have been successfully shipped to Germany. This bulk export marks a key breakthrough for domestic Far-UVC core optoelectronic components entering the high-end European commercial and industrial supply chain, further consolidating Excimerlight's leading position in the global filter-free far-ultraviolet lighting industry.
Core Technology Advantages: Breakthrough Filter-Free DBD Technology
Different from traditional 222nm excimer lamps that rely on external optical bandpass filters, this batch of 6W far-UVC lamps adopts original filter-free technical route and optimized Dielectric Barrier Discharge (DBD) structure, solving the industry pain points of filter aging, light attenuation and high maintenance cost, with superior comprehensive performance:
1. High Spectral Purity with 6N High-Purity Quartz & Precise Gas Ratio Equipped with self-developed 6N-grade high-purity quartz glass and precision krypton-chloride (KrCl) gas proportioning technology, the product optimizes the internal discharge cavity structure. It stably outputs pure 222nm far-ultraviolet spectrum without any optical filter, effectively isolating harmful ultraviolet wavebands above 230nm, achieving ultra-high spectral purity and meeting international safety standards for occupied-space disinfection.
2. Zero Consumable Loss & Lower Full Lifecycle Cost Traditional filtered UVC lamps are prone to filter solarization, yellowing and transmittance attenuation during long-term operation, resulting in decreased sterilization efficiency and frequent replacement costs. Our filter-free excimer solution completely eliminates optical consumable failure risks, effectively improving radiant flux stability, extending product service life, reducing LCOE (Levelized Cost of Energy), and realizing maintenance-free long-term operation.
3. Low Power Consumption & Full EU Standard Compliance Featuring 6W low-power design and high electro-optical conversion efficiency, the lamp has excellent thermal management performance and strong compatibility. It is widely applicable for commercial air disinfection, public space dynamic sterilization and surface inactivation scenarios. All products fully comply with EU CE certification, RoHS environmental directives and EMC electromagnetic compatibility standards, meeting strict European market access thresholds.
High-End Market Recognition: Passed 6-Month German Third-Party authoritative Testing
Germany is a global highland of optoelectronic manufacturing, with extremely strict assessment standards for UV light source indicators including spectral consistency, irradiance decay curve, batch stability and long-term operational reliability.
Before this bulk order delivery, Excimerlight's filter-free 222nm excimer lamps successfully passed 6 consecutive months of third-party laboratory testing designated by the German end-user. Core parameters such as UV irradiance retention rate, safe spectral distribution and MTBF (Mean Time Between Failures) have reached and exceeded the performance level of European mainstream brands. The stable and reliable filter-free technology solution has won high recognition from German professional clients.
Global Layout: Full-Series VUV & Far-UVC Excimer Light Source Mass Production Strength
As one of the few domestic manufacturers with independent R&D and mass production capacity of filter-free 222nm excimer lamps, Excimerlight has long focused on the industrialization of vacuum ultraviolet and far-ultraviolet core technologies. At present, the brand has built a complete product matrix covering 163nm VUV, 172nm and 222nm full-band excimer light sources, with a stable monthly production capacity of 10,000–30,000 units.
Our products are widely exported to Germany, other European countries, North America, the Middle East and Israel, covering diversified application fields including occupied space intelligent disinfection, industrial surface modification, PCB ultra-cleaning, semiconductor micro-nano processing, VUV excimer curing and ultrapure water treatment.
In the future, Excimerlight will continue to deepen R&D innovation in DUV semiconductor light sources and gas discharge technology, provide customized OEM/ODM professional UV solution for global clients in line with regional safety specifications, and further expand the global high-end optoelectronic market layout.
