222 nm vs 254 nm against Norovirus — NUS study quantifies the penetration trade-off
Singapore researchers ran the first systematic head-to-head of 222 nm Far-UV-C and classical 254 nm UV-C against human norovirus on real surfaces — and found a sharp trade-off rather than a clean win for the safer wavelength.
Excimerlight Enters North America With Filter-Free 222 nm Far-UVC Platform
Far-UVC manufacturer Excimerlight has announced its market entry into North America with a KrCl-excimer platform spanning 3 W to 1000 W. The vendor claims its lamp-optical architecture suppresses out-of-band emission above 230 nm in the source itself, eliminating the degrading bandpass filter that has been the Achilles heel of the dominant Ushio Care222-class platforms.
Silanna UV SF2 — Next-Generation Far-UVC LED Doubles Radiant Intensity at 230 nm
Silanna UV has released the second generation of its Far-UVC LED line: SF2 reaches a typical center wavelength of 233 nm at 2 mW/sr radiant intensity per the vendor datasheet — twice the predecessor SF1, in a TO-Can package with 17° beam angle.
