Care222® filtered 222 nm far UV-C disinfection lamps

Care222® Far-UVC Excimer Ultraviolet Germicidal Irradiation (UVGI) Lamps

Ushio is proud to introduce the Care222® series, a new line of filtered 222 nm far UV-C excimer lamps for microbial reduction.

Care222 lamps are presently used for unoccupied spaces, with studies ongoing as we seek to make Care222 disinfection lamps the number one choice for occupied microbial reduction solutions too. Ushio’s longstanding collaborations with scientific institutions have contributed to the development of a system which selectively kills bacteria and inactivates viruses without damaging human cells/tissues using narrow-band spectrum UV. This has been made possible through the use of a new patented wavelength filtration technology. The system has demonstrated its ability to inactivate all kinds of ‘super bugs’ such as MRSA, influenza, MERS-CoV, as well as killing viruses including Ebola, and SARS-CoV-2, the virus which triggered the COVID-19 Coronavirus pandemic.

These mercury-free, instant-on excimer lamps are ideal for bathrooms, toilets, counter tops, and other occasional-use applications.

Ushio can provide a lamp that meets your disinfection needs. Fill in the Care222® product questionnaire, and we will deliver the best-suited Ushio excimer expert to you. We have detailed some key features of the Care222 UV disinfection module below, however, for a detailed analysis of technical specifications and capabilities, please click here.

  • Cost effective – While the initial outlay for a Care222 lamp may be higher than that of a conventional UV lamp, the following benefits clearly offset any budget concerns once usage has begun.
  • Ushio’s studies alongside some of the world’s most prestigious research institutions have found Care222 lamps to be more effective than conventional UV in many bacterial eradication applications.
  • Mercury-free – disposal of the lamp is environmentally friendly and poses very little in the way of safety risk should the lamp break. This is also important as intensifying restrictions on the usage and disposal of mercury will be implemented in the coming years.
  • Instant-on/off – The skilled engineering behind the Care222 lamp allows customers to obtain full irradiation output in less than one second, whereas conventional germicidal lamps start at only 50% output and take several minutes to ramp up to 100% output.
  • Flexible design capabilities for customised lamp development.
  • Filters out almost all unnecessary and hazardous wavelengths to maintain a highly effective and human exposure-safe output of the 222 nm germicidal wavelength.
  • Highly effective inactivation and reduction of the majority of spores, in fact, 222 nm has proven to be more effective than 254 nm UVGI solutions in most cases.
  • Operable in a wide range of temperatures, unlike conventional 254 nm lamps.
  • Ideal for indoor and outdoor applications.

Important safety considerations regarding the usage of Care222 emitters

The Care222 modules are not a standalone product and do not currently carry a CE certification. The Ushio Care222 series of products consists of individual components which are strictly intended for integration into solutions produced by original equipment manufacturers (OEMs). OEMs operating within the European Economic Area (EEA) are bound by mandatory European health, safety, environmental, and electrical standards, which subsequently advocates their full responsibility to correctly inform the end-user of any risk factors, restrictions, and necessary safety protocol.

For this reason, Care222 products cannot be supplied to end-users or private individuals.

Since the final design, specifications, and price for Care222 components may change in future, we are not at liberty to discuss volume and/or discounts at this time.

Please consider that regulations pertaining to human exposure to ultraviolet radiation wavelengths, including those emitted by Care222® products, are outlined in the EU directive 2006/25/EC.
