5W 222nm Far UVC Light Kill Virus and Human Skin Safety For Public Use

The 5W 222nm Far UVC Light is a compact excimer-based Far-UVC light source designed for public-area disinfection equipment, ceiling-mounted fixtures, wall-mounted modules, portable devices, access control systems, and custom OEM sterilization solutions. With filtered 222nm emission, low power consumption, and flexible installation options, it is suitable for manufacturers developing UV disinfection products for occupied or semi-occupied environments.

Compared with traditional 254nm UVC lamps, 222nm Far-UVC light has a much shorter wavelength and is widely studied for its limited penetration into the outer dead-cell layer of human skin and the tear layer of the eye. When properly filtered, shielded, and controlled within applicable exposure limits, it can support safer disinfection system designs for public spaces.

This 5W Far-UVC lamp is ideal for OEM equipment manufacturers that need a compact, mercury-free UV light source for public hygiene products, air disinfection fixtures, surface irradiation modules, and smart sterilization systems.

Key Features

Filtered 222nm Far-UVC Technology
The lamp is designed to provide 222nm Far-UVC output with optical filtering support to reduce unwanted longer UV wavelengths. This helps equipment manufacturers create more controlled and application-specific UV disinfection systems.

Compact 5W Power Design
The 5W configuration is suitable for compact disinfection modules, low-profile fixtures, small public-area devices, and equipment designs where limited space and controlled UV output are required.

Designed for Public Use Applications
This Far-UVC light source can be integrated into disinfection fixtures for public and commercial spaces, including offices, schools, clinics, retail areas, transport facilities, elevators, corridors, and shared indoor environments.

Mercury-Free Excimer Light Source
The product uses excimer Far-UVC technology and does not contain mercury, supporting cleaner and more environmentally responsible UV equipment design compared with traditional mercury-based UV lamps.

Human-Exposure-Conscious Design
222nm Far-UVC technology is commonly used in systems designed for controlled public-area disinfection. Final equipment should include suitable optical filters, shielding, occupancy sensors, exposure-time control, and safety interlocks to help keep UV exposure within applicable standards.

Stable UV Output for OEM Equipment
The lamp is engineered for stable ignition and consistent UV performance when matched with a suitable power supply. It can be used as the core light source in OEM disinfection products requiring reliable operation and repeatable output.

Flexible Integration
PurLightTech can support OEM and ODM customers with lamp dimension customization, mounting structure, reflector design, electrical matching, prototype development, and mass production supply.

Typical Applications
This 5W 222nm Far-UVC light source can be integrated into a wide range of public-use and commercial disinfection equipment, including:

Ceiling-mounted Far-UVC disinfection fixtures

Wall-mounted narrow-beam disinfection modules

Elevator and corridor UV irradiation units

Portable public-area disinfection devices

Air purification and upper-room air disinfection systems

Healthcare waiting room and clinic disinfection equipment

School, university, and daycare hygiene systems

Office, meeting room, and retail disinfection fixtures

Airport, train station, and public transit disinfection systems

Hotel, restaurant, library, and museum hygiene equipment

Access control and passageway disinfection devices

Custom OEM Far-UVC sterilization products

Why Choose This 5W 222nm Far-UVC Light?

Suitable for Compact Public-Area Devices
The 5W output makes this lamp suitable for smaller fixtures and distributed disinfection systems. Multiple lamps can also be arranged in arrays depending on the required irradiation area and equipment design.

Better Fit for Occupied-Space Concepts
For public-use UV systems, safety design is critical. 222nm Far-UVC technology provides an important option for manufacturers developing controlled UV products intended for occupied or semi-occupied areas, provided that the final system is properly filtered, tested, and compliant with exposure regulations.

OEM-Ready Light Source
This product is developed for equipment manufacturers rather than only for end-user replacement. It can be integrated into ceiling fixtures, wall units, air treatment products, portable equipment, and customized disinfection platforms.

Engineering Support Available
PurLightTech supports customers from early concept to mass production, including optical layout, mechanical structure, power supply matching, prototype testing, UV performance validation, and production consistency control.

Technical Advantages

Narrowband 222nm Emission
The lamp is designed around 222nm excimer Far-UVC output. With suitable filter technology, it helps reduce non-target UV wavelengths and supports more precise disinfection equipment design.

Low Heat and Compact Structure
The 5W power level allows easier integration into compact housings, low-profile public fixtures, and embedded disinfection products where thermal management and space are important.

Instant-On Operation
The lamp supports fast start-up performance, making it suitable for systems that require scheduled operation, sensor-triggered operation, or controlled intermittent disinfection cycles.

Custom Optical Design
Different public spaces require different irradiation patterns. PurLightTech can support reflector design, beam angle optimization, irradiation uniformity improvement, and module-level customization.

Matched Power Supply Options
A properly matched driver is essential for stable operation. Power supply matching can be provided to support reliable ignition, continuous operation, and long-term system performance.

OEM Development Support
PurLightTech provides a structured development process for manufacturers building 222nm Far-UVC products:

Customer requirement review

Application and installation analysis

Optical simulation and irradiation planning

Mechanical housing and mounting design

Lamp sample and prototype development

UV output and lifetime validation

Mass production and quality control support

Safety and Compliance Notes
Although 222nm Far-UVC is widely researched for public-space disinfection applications, final safety depends on the complete equipment design. 

The final product should include appropriate optical filters, shielding, sensor control, installation instructions, warning labels, and exposure-limit validation. UV exposure levels should be tested according to relevant safety standards before the equipment is used in public environments.



Disinfection Performance Notes
The actual virus or bacteria inactivation effect depends on UV dose, exposure time, distance, air movement, surface material, shadowing, humidity, target microorganism, and equipment layout. Performance should be validated through application-specific microbiological testing.
