Portable UVC Disinfection Lamp with Quartz Tube for 2m² Surface and Air Sterilisation

This portable ultraviolet disinfection lamp provides a practical method for germicidal treatment in small, enclosed spaces. Designed around a UVC-emitting quartz tube, it delivers light at the 253.7nm wavelength, which is known for its effectiveness against microorganisms. With a measured irradiance of 850μw/cm² (±10%), it is engineered to decontaminate surfaces and air within an area of up to 2 square metres. The compact, capsule-shaped housing measures just 52mm by 52mm by 136mm, making it highly portable for use in cars, hotel rooms, bathrooms, or on office desks. Its cordless capability, powered by an integrated 700mAh battery rechargeable via a standard 5V USB port, adds to its convenience for mobile applications.

Technical Specifications and Performance

The lamp's performance is defined by its core technical parameters, which determine its suitability for various decontamination tasks. These specifications provide a clear understanding of its operational scope and limits.

UVC Output and Coverage

The lamp operates at a UVC wavelength of 253.7nm, with an irradiance level of 850μw/cm², subject to a tolerance of ±10%. This output is the key metric for its germicidal efficacy. It is designed to treat an area not exceeding 2 square metres, with a recommended exposure time of 30 minutes to achieve the intended disinfection effect. Users should ensure the lamp is positioned to allow the UVC light to reach all surfaces within this defined space.

Power and Runtime

Rated at 3W, the lamp draws power efficiently. For cordless operation, it relies on a built-in 700mAh lithium battery. The runtime provided by this battery capacity is directly linked to the power consumption during use. The unit can also be powered continuously via its 5V DC USB input port, which serves as the charging source for the internal battery. This dual power flexibility supports both mobile and stationary use cases.

Physical Design and Options

The product features a distinctive capsule form factor. The primary lamp body dimensions are 52mm in width, 52mm in depth, and 136mm in height. When including any external protrusions or the full packaging, the total dimensions are 64mm by 64mm by 148mm. It is offered in four distinct colour variants: black, brown, green, and white, allowing it to blend into different environments from professional settings to personal spaces.

Practical Application and Use Cases

Understanding where and how to use this lamp safely and effectively is crucial for achieving the desired sterilisation results while adhering to important safety protocols.

Safe Operational Procedure

UVC light is harmful to eyes and skin. Therefore, the lamp must only be operated in unoccupied spaces. All people, pets, and sensitive plants must vacate the room for the duration of the disinfection cycle. It is intended for surface and air disinfection, not for direct application on skin or for sanitising liquids. Always start the timer and leave the room immediately after switching the device on.

Ideal Environments for Use

Its portability and 2m² coverage make it suitable for small, enclosed areas. Common applications include sanitising the interior of a vehicle, a hotel bathroom, a small home office, a wardrobe, or a nursery room between uses. It is particularly useful in situations where chemical sprays are undesirable or where a quick, automated decontamination cycle is needed.

Maintenance and Lamp Life

The core disinfection component is a quartz glass tube lamp. The manufacturer states this tube has an approximate lifespan of 8000 hours of operation. This extended life translates to a high number of individual 30-minute disinfection cycles. Maintenance is minimal, primarily involving keeping the quartz tube clean and free of dust to maintain optimal UVC light transmission and ensuring the USB port and battery are cared for according to general electronic device guidelines.

Value and Key Decision Factors

When considering this disinfection lamp, its value stems from specific, source-supported attributes that differentiate it from simpler sanitising methods.

Reusability and Cost-per-Use

The 8000-hour lamp life is a significant functional longevity claim. When used for standard 30-minute sessions, this permits thousands of disinfection cycles over the product's lifetime, offering a reusable alternative to disposable wipes or single-use chemical kits. This reusability can contribute to reduced long-term expenditure on consumable disinfectants.

Why Choose This UVC Lamp

This product combines measured UVC irradiance (850μw/cm²) with genuine portability, defined by its compact size and battery option. The specified 2m² treatment area provides a clear usage boundary, ensuring realistic expectations. The availability of multiple colours (black, brown, green, white) also offers a degree of personalisation not always found in functional electronic devices. For users seeking a compact, purpose-built UVC device with stated technical specifications, this lamp presents a clearly defined solution.
