Product Details
SBS-222-20W Far UVC Lamp for UV Systems with Compact Design
The lamp SBS-222-20W is a compact far UVC lamp for utilization of manufacturers, engineering companies and system integrators who need 20W ultraviolet source in a compact cylindrical design. The diameter of this lamp is Φ28 × 120 mm and it may be assembled in suitable housings in case of restricted areas for installation.
Adjustable Electrical Setup
This lamp can be used in DC24V and 220V electrical systems. As a result, the developer can pick up the suitable electrical setup according to the power circuitry of the final product. The necessary voltage, driver, wiring diagram, connection, grounding and control strategy should be defined during the development process.
Specified UV Intensity
The SBS-222-20W far UVC lamp provides the intensity of 4000 μW/cm². Because of the dependence of the intensity on the distance from the lamp, UV sensor calibration, reflector design, lamp location, operating time and other environmental factors, the customer has to specify the target testing point before testing the lamp in specific application.
Quartz Glass Bulb
The quartz glass bulb provides UV protection of the lamp and at the same time its UV transmission. This small-sized Φ28 × 120 mm bulb is perfect for integration in compact fixtures, replacement lamps, treatment chambers, custom UV systems.
Operation Temperature and Lifespan
This lamp operates in the ambient temperature range from -10°C to +50°C. The lifespan of this UV source exceeds 4000 hours under specified operating conditions. The thermal management, switching frequency, power stability, contamination and installation quality can influence the service performance.
Customizable Integration for Specific Applications
This product can be considered for utilization in air-treatment devices, surface-treatment devices, laboratory devices, enclosed sanitation devices and UV systems. The suitability of this product for the specific application should be verified by the performance, exposure control, microbial reduction, ozone generation, spectral distribution and regulatory requirements.

2. Which voltage options are available?
The SBS-222-20W is available in DC24V or 220V versions. Select the correct version for the power supply and control system used in your equipment.
3. What is the specified UV intensity?
The specified UV intensity is 4000 μW/cm². The actual value measured in a finished system can vary according to distance, optical design, lamp orientation, sensor type, and operating conditions.
4. What material is used for the bulb casing?
The far UVC lamp uses a high-purity quartz glass casing.
5. How long is the rated bulb lifetime?
The rated bulb lifetime is more than 4000 hours when the lamp is operated under appropriate electrical, thermal, and environmental conditions.
6. Can the lamp operate in low-temperature environments?
The specified ambient operating temperature range is -10°C to +50°C.
7. Is this product suitable for occupied-space use?
Occupied-space suitability cannot be determined from electrical power and UV intensity alone. The complete fixture must be assessed for verified wavelength, spectral filtering, exposure dose, installation height, operating time, ozone, and applicable safety limits.
8. Is the wavelength confirmed as 222 nm?
The provided specification does not state the peak wavelength or filter configuration. Confirm these values with a verified spectral test report before publishing a 222 nm, filtered, ozone-free, or occupied-space safety claim.
