Product Details
20W Far UVC Lamp for Compact UV System Design
The yoyouv SBS-222-20W is a compact far UVC lamp developed for manufacturers, engineering companies, and system integrators that require a 20W ultraviolet source in a short cylindrical format. Measuring Φ28 × 120 mm, the lamp can be incorporated into compatible housings where installation space is limited.
Flexible Electrical Configuration
The far UVC lamp supports DC24V or 220V configurations. This allows developers to select an electrical version that matches the power architecture of the final device. The required voltage, driver, wiring method, connector, grounding, and control logic should be confirmed as part of the complete system design.
Specified UV Output
The product is rated at 4000 μW/cm² UV intensity. Because UV intensity changes with measurement distance, sensor calibration, reflector design, lamp orientation, operating time, and environmental conditions, buyers should define the target test position and acceptance method before evaluating the lamp in an application.
Quartz Glass Bulb Construction
A high-purity quartz glass casing protects the lamp structure while supporting UV transmission. The Φ28 mm diameter and 120 mm length make this UV source suitable for compact fixtures, replacement-lamp concepts, enclosed treatment chambers, and customized UV equipment.
Operating Range and Service Life
The SBS-222-20W is designed for ambient temperatures from -10°C to +50°C. Its rated lifetime is more than 4000 hours under specified operating conditions. Thermal management, switching frequency, power stability, contamination, and installation quality may affect actual service performance.
Application-Oriented Integration
This product can be evaluated for engineered air-treatment equipment, surface-treatment systems, laboratory devices, enclosed sanitation equipment, and UV assemblies. Application suitability, exposure control, microbial reduction performance, ozone generation, spectral output, and regulatory compliance must be verified in the completed system.

Frequently Asked Questions
1. What are the dimensions of the SBS-222-20W?
The far UVC lamp measures Φ28 × 120 mm, making it suitable for compact equipment layouts and customized housings.
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.
