Product Details
Compact 3.5W Far UVC Light Source
The yoyouv SBS-222-3W is a compact far UVC 222nm lamp created for equipment manufacturers, product developers, research teams, and system integrators that need a small ultraviolet source. Its Φ15 × 65 mm dimensions allow the component to fit into compatible compact housings, enclosed chambers, test fixtures, and customized UV assemblies.
The product combines a 3.5W bulb rating with DC3.7–5V operation. This low-voltage configuration gives designers flexibility when developing portable or compact equipment. The final power system should provide the required input while accounting for the lamp’s electrical characteristics, connection method, switching controls, and operating environment.
Specified UV Intensity
The far UVC 222nm lamp has a specified UV intensity of 600 μW/cm². UV intensity at the target area may change according to the measuring distance, sensor position, fixture geometry, reflector design, lamp orientation, operating temperature, and test equipment.
For reliable product development, buyers should define the measurement distance and acceptance method before comparing samples or approving production. Adding the test distance and radiometer model to the product specification sheet will make the intensity information more useful to engineers and purchasing teams.
High-Purity Quartz Glass Construction
High-purity quartz glass is used for the bulb casing. This construction gives the far UVC 222nm lamp a compact, professional component format while supporting ultraviolet output through the casing.
The lamp weighs 100 g, helping equipment designers manage component placement and total assembly weight. The compact dimensions also make it easier to evaluate the lamp in products with restricted internal installation space.
Operating Temperature and Service Life
The specified ambient operating range is -10°C to +50°C. Within an appropriately designed system, the far UVC 222nm lamp offers a rated bulb life of more than 4000 hours.
Actual service performance can be influenced by power stability, thermal conditions, switching frequency, installation quality, contamination, and the operating cycle of the finished equipment. The final fixture should therefore be tested under its intended operating conditions.
Integration and Application Evaluation
The SBS-222-3W can be evaluated as a component for compatible air-treatment devices, surface-treatment equipment, enclosed sanitation units, laboratory instruments, and specialized UV systems.
Every far UVC 222nm application should be validated in the completed fixture rather than judged from lamp wattage or intensity alone. Application testing should consider the distance between the lamp and target, required exposure time, fixture geometry, electrical controls, and expected operating cycle.
Before commercial deployment, the completed product should be evaluated for optical output, exposure control, electrical safety, thermal performance, installation distance, operating time, and application-specific requirements.
The supplied specifications do not state whether an optical filter is included. Filtered output and out-of-band emission performance should therefore be confirmed separately when these characteristics are required by the finished 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.
