Far UVC 222nm 3W Small Size Quartz UV Light Tube for Food and Clothing Surface Disinfection

The Far UVC 222nm 3W Small Size Quartz UV Light Tube is a compact excimer-based Far-UVC lamp designed for OEM disinfection equipment, food surface treatment modules, clothing surface disinfection devices, small sterilization boxes, storage cabinets, and custom UV hygiene systems. With a small-size quartz tube structure, low power consumption, and filtered 222nm emission, it is suitable for manufacturers developing compact disinfection products for daily hygiene, commercial equipment, and industrial surface treatment applications.

Compared with traditional 254nm UVC lamps, 222nm Far-UVC light has a 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 UV disinfection system designs for selected public, commercial, and indoor applications.

This 3W quartz UV light tube is especially suitable for compact equipment where space is limited but stable Far-UVC output is required, such as clothing care devices, food storage disinfection modules, shoe cabinets, small appliance sterilization chambers, and OEM surface disinfection systems.

Key Features

Compact 3W Far-UVC Light Source
The 3W power design makes this lamp suitable for small UV disinfection equipment and embedded sterilization modules. Its compact size allows flexible integration into cabinets, boxes, drawers, racks, and other limited-space structures.

Filtered 222nm Emission
The lamp is designed to provide 222nm Far-UVC output with optical filtering support to help reduce unwanted longer UV wavelengths. This helps manufacturers build more controlled UV disinfection systems for food, clothing, and high-touch surface applications.

Small Size Quartz Tube Construction
The lamp uses a quartz tube structure designed for UV transmission, durability, and stable operation. The small-size tube format makes it easier to integrate into compact equipment without occupying excessive internal space.

Designed for Food and Clothing Surface Disinfection
This Far-UVC lamp can be integrated into equipment for treating the surface of packaged food, food containers, clothing, towels, shoes, fabric items, and other frequently handled objects. Final effectiveness depends on UV dose, exposure time, distance, surface texture, and equipment layout.

Energy-Efficient Operation
With a 3W power rating, the lamp is suitable for low-power disinfection devices and products that require scheduled or repeated operation. It helps reduce energy consumption while supporting compact sterilization system design.

Instant-On Performance
The lamp can reach operating output quickly after activation, making it suitable for equipment with timed cycles, sensor-triggered operation, or frequent on/off use. This is useful for small disinfection boxes, storage cabinets, and smart hygiene appliances.

Mercury-Free Excimer Technology
This Far-UVC light tube uses excimer technology and does not contain mercury, helping OEM manufacturers develop cleaner and more environmentally responsible UV disinfection products compared with traditional mercury-based UV lamps.

OEM Integration Support
PurLightTech supports OEM and ODM customers with lamp customization, power supply matching, reflector design, installation structure, prototype testing, and mass production supply. The lamp can be adapted for different product structures and application requirements.

Why Choose This 3W 222nm Far-UVC Lamp?

Ideal for Compact Equipment Design
The small-size quartz tube structure allows manufacturers to integrate Far-UVC technology into compact products where conventional UV lamps may be too large. It is suitable for embedded installation inside cabinets, storage boxes, clothing care devices, and surface disinfection equipment.

Suitable for Daily Surface Hygiene Applications
Food packaging, clothing, towels, shoes, and frequently touched objects often require compact and convenient disinfection solutions. This 3W Far-UVC lamp provides a practical light source option for manufacturers developing daily-use hygiene equipment.

Controlled Human-Exposure Design Potential
222nm Far-UVC technology is commonly researched for applications where controlled exposure may be required. However, final product safety depends on the complete system design, including optical filtering, shielding, exposure time control, installation position, warning labels, and compliance testing.

Stable UV Output for OEM Products
Stable output is important for repeatable disinfection equipment performance. When paired with a suitable power supply and optimized mechanical structure, this lamp can provide reliable operation for small UV devices and commercial hygiene systems.

Flexible Customization Options
Different devices require different lamp dimensions, connector layouts, mounting structures, and irradiation patterns. PurLightTech can support customized design according to your equipment housing, irradiation area, and production requirements.

Technical Advantages

Narrowband 222nm Far-UVC Technology
The lamp is designed around 222nm Far-UVC excimer technology. With appropriate filtering, it helps reduce non-target UV wavelengths and supports more precise surface disinfection equipment design.

High-Purity Quartz Glass
The quartz tube structure supports UV transmission and stable lamp operation. It is suitable for compact lamp designs that require durability, reliability, and consistent optical performance.

Low Ozone Design Consideration
For indoor and enclosed applications, ozone control is important. The lamp can be designed with filtering and system-level control to help reduce unwanted byproducts. Final ozone performance should be verified based on the complete equipment structure and operating conditions.

Low Power Consumption
The 3W design helps equipment manufacturers develop compact UV products with lower energy use, reduced heat generation, and easier thermal management.

Fast Start and Flexible Control
The lamp supports quick activation and can be used in timed disinfection cycles, automatic control systems, cabinet-door interlock systems, and smart appliance designs.

Safety and Compliance Notes

Although 222nm Far-UVC is widely studied for its different interaction depth compared with conventional 254nm UVC, it should not be described as completely harmless under all conditions. Final safety depends on wavelength filtering, UV intensity, exposure time, distance, installation method, and the complete equipment design.

For food and clothing surface disinfection equipment, the lamp should be integrated with suitable shielding, interlock protection, exposure control, and user instructions. UV exposure levels should be tested according to applicable safety standards before the product is released for public or consumer-facing use.


Disinfection Performance Notes
Actual disinfection performance depends on UV dose, irradiation distance, exposure duration, surface reflectivity, object shape, fabric texture, shadowing, humidity, and the target microorganism. For food and clothing applications, manufacturers should validate performance through application-specific testing.
