Product Details
Compact 3.5W Far UVC Light Source
The yoyouv SBS-222-3W is a compact far UVC 222nm lamp made for equipment manufacturers, product developers, research groups, and system integrators who require a compact ultraviolet light source. Dimensions of Φ15 × 65 mm allow this component to integrate into compact housings, enclosures, fixtures, and custom UV assemblies.
This product is characterized by a combination of a 3.5W bulb rating and DC3.7–5V power supply. Low voltage of this far UVC 222nm lamp allows the designer to develop portable or compact equipment. Power supply system should be developed in such a way to deliver required power taking into account electrical characteristics of the lamp, connection method, switching controls, and operating environment.
Specified UV Intensity
Specified UV intensity of the far UVC 222nm lamp is equal to 600 μW/cm². UV intensity on the target area can be varied depending on the measuring distance, position of the sensor, fixture design, reflector design, lamp orientation, operating temperature, and test equipment.
In order to develop the reliable product, buyers should specify the distance of measurement and criteria of acceptance before comparing samples and approving production. Specification of the test distance and radiometer model will increase the value of information about the intensity to engineers and purchasing department.
High-Purity Quartz Glass Construction
High-purity quartz glass was used for construction of the bulb. It allows the construction of a compact professional component for ultraviolet light source while supporting the ultraviolet radiation through the casing.
Weight of this lamp is 100 g and it allows equipment designers to estimate component placement and total weight of the assembly. Compact dimensions allow to estimate the lamp in products with limited internal installation space.
Operating Temperature and Service Life
Specified ambient operating temperature range is from -10°C to +50°C. In properly designed system, far UVC 222nm lamp provides rated bulb life for more than 4000 hours.
Service performance can depend on power stability, thermal conditions, switching frequency, installation quality, contamination, and operating cycle of the final equipment. Final fixture should be tested under the conditions of its intended use.
Integration and Application Evaluation
SBS-222-3W can be evaluated as a component for compatible air-treatment equipment, surface treatment equipment, enclosed sanitation equipment, laboratory equipment, and UV systems.
Every far UVC 222nm application should be validated in the completed fixture instead of evaluation of lamp parameters like wattage and intensity. Evaluation of application should take into account distance from the lamp to the target, required exposure time, fixture geometry, electrical controls, and operating cycle of the final equipment.
Before commercial application, the product should be evaluated for optical output, exposure control, electrical safety, thermal performance, installation distance, operating time, and other application-specific requirements.
The specifications provided by the manufacturer do not include information if the optical filter is provided. Filtered optical output and out-of-band emission performance should be checked separately in case if it is required for the final product.

Frequently Asked Questions
1. What are the dimensions of the SBS-222-3W?
The lamp measures Φ15 × 65 mm. This compact format makes the far UVC 222nm component easier to evaluate for small housings and customized UV equipment.
2. What voltage does the lamp require?
The specified input voltage is DC3.7–5V. A compatible power supply and control system should be selected for the final device.
3. What is the bulb power?
The SBS-222-3W has a bulb power rating of 3.5W.
4. What is the specified UV intensity?
The specified UV intensity is 600 μW/cm². Results in a finished fixture may vary with measurement distance, optical layout, lamp orientation, and test conditions.
5. What material is used for the bulb casing?
The far UVC 222nm lamp uses high-purity quartz glass as its bulb casing.
6. What is the operating temperature range?
The specified ambient operating temperature range is -10°C to +50°C.
7. How long is the rated bulb life?
The rated lifetime is more than 4000 hours under appropriate operating conditions.
8. Does the lamp include an optical filter?
The supplied specifications do not confirm an integrated optical filter. Buyers should request the spectral curve, filter information, and out-of-band emission data when filtered far UVC 222nm output is required.
9. Can the lamp be described as safe for occupied spaces?
Occupied-space suitability depends on the complete fixture, verified spectrum, filtering, exposure dose, installation, operating time, and applicable safety requirements. An unrestricted human-safety claim should not be based only on wavelength, bulb power, or UV intensity.
10. What information should buyers confirm before ordering?
Buyers should confirm the required quantity, power supply compatibility, installation dimensions, UV intensity test distance, spectral test data, filter requirements, and intended equipment configuration.
