Researchers from Tel Aviv University found that UV light at a wavelength of 285 nm was almost as efficient in disinfecting the Covid virus as a wavelength of 265 nm, requiring less than half a minute to destroy more than 99.9% of the coronaviruses. They say this result is significant because the cost of 285-nm […]

UV-C LED modules designed for sterilization
Sensor Electronic Technology, Inc. (SETi) and Seoul Viosys have started mass production of a UV LED module designed to sterilize 99.9% of the coronavirus in three seconds using “Violeds,” a UV LED technology developed by Seoul. Seoul Viosys is also developing a “Photon Shower” device that applies the UV LED technology to contribute to the […]
Shedding light on how much UV-C you need for disinfection
The idea of using UV-C light to kill the COVID-19 virus by disrupting its RNA has captured the imagination of many in the technical community. Unfortunately, important application details about factors such as necessary exposure time and intensity levels may be hard to discern, particularly for those who are new to the technology. A complicating […]
Teardown: When it comes to germicidal lights bought online, buyer beware
During the coronavirus pandemic, there’s been a lot of interest in using germicidal lamps to disinfect surfaces rather than hosing everything down with bleach or disinfectant. But there have been reports that a lot of the germicidal lights based on LEDs are actually fake. So we did a little test. We went online and bought […]
When it comes to UV-C LED lights, buyer beware
During the coronavirus pandemic, there’s been a lot of interest in using germicidal lamps to disinfect surfaces rather than hosing everything down with bleach or disinfectant. Lamps are a little easier to work with when you’ve got things like knobs, buttons, and slider controls on test instruments that may not do well when doused with […]
Prioritized orders, free product samples to support COVID-19 efforts and medical applications
CUI Devices has announced new initiatives in its support of the medical industry’s response to the global coronavirus (COVID‑19) pandemic. These initiatives include prioritizing orders and expediting free product samples to OEMs, makers, volunteers, and organizations designing medical equipment key to fighting COVID‑19, such as respirators, ventilators, blood analysis machines, test equipment, patient monitors, imaging […]
Free-of-charge samples speed medical equipment designs
RECOM announced that the COVID-19 crisis has resulted in an increase in the demand for their medical-grade DC/DC, and AC/DC converters. These modules range from 1 W – 550 W with 2xMOPP and have UL/IEC/EN60601 3rd Ed. Certification. In an effort to provide access to their products as quickly as possible, they are offering free […]
Killing Covid-19 with UV-C LEDs
Yes, light in the UV-C part of the spectrum will destroy the virus. Here are the basics and a few myths surrounding these light emissions. For those of us still working, it can be a bit unsettling to ponder whether the surfaces we touch harbor a few virions left over from someone infected with Covid-19. […]
