As a professional certified manufacturer of PL-S Series H-Shaped UV Lamp PL-S13W in China, Kingrate provides standardized B2B-grade UV lamp configurations for global commercial procurement. This lamp adopts a compact structural design with a 12mm outer diameter and universal G23 single-ended base. It achieves a standard service life of 9,000 hours with UV light decay strictly controlled below 30% throughout the service cycle, eliminating frequent replacement troubles and additional maintenance costs for end users.
Conventional germicidal UV bulbs suffer from rapid light attenuation and unstable ozone by-product generation, which may damage precision equipment and pollute application environments. Kingrate PL-S Series H-Shaped UV Lamp PL-S13W delivers stable and pure 253.7nm UVC band radiation, adapting to multiple high-standard commercial and industrial scenarios:
Effectively eliminates airborne bacteria, viruses and microorganisms in hospital ventilation systems, laboratory cleanrooms and sterile operating environments, with no harmful secondary gas generation to ensure environmental safety.
Compatible with compact water sterilization equipment, widely used in residential drinking water purification, commercial aquarium filtration and aquaculture farms to inhibit pathogen reproduction and algae growth, purifying water quality stably.
Installed on food conveyor belts and internal packaging machinery for surface microbial decontamination. It extends food shelf life thoroughly without chemical residue, meeting food safety production standards.
As a low-pressure mercury germicidal lamp with optimized structural design, PL-S Series H-Shaped UV Lamp PL-S13W supports long-term continuous operation in narrow installation spaces while maintaining precise and stable UVC output intensity. The core parameters are as follows:
• Power Consumption: 13W
• Lamp Base Type: G23 single-ended 2-pin plug
• Physical Dimensions: Outer diameter 12 mm, overall length 155 mm
• Operating Lifespan: 9,000 hours (standard configuration); up to 13,000 hours (upgraded filament configuration)
• UVC Spectral Peak: 253.7 nm (Ozone-free)
• UV Light Decay Rate: Less than 30% at the end of the rated operating lifespan
Different from ordinary commercial soft glass bulbs with unstable performance, Kingrate relies on high-purity raw materials and fully automated precision production processes to ensure heavy-duty industrial-grade durability and stable performance of PL-S Series H-Shaped UV Lamp PL-S13W.
Adopts high-purity quartz glass with ultra-high UVC transmittance. The material features excellent thermal stability and anti-solarization performance, resisting aging and light attenuation caused by long-term continuous ultraviolet irradiation.
Equipped with automatic filament winding and precision mercury dosing equipment to ensure uniform gas filling and consistent filament parameters for each lamp. It completely avoids performance differences caused by manual production errors.
A special protective barrier coating is applied inside the quartz tube, which isolates the affinity reaction between mercury and the tube wall. It fundamentally solves the common problems of tube blackening and sharp UV output decline in traditional UV lamps.
Subtle structural and process differences bring huge long-term operational cost advantages for municipal water treatment, medical equipment and industrial supporting scenarios. The detailed comparison is shown below:
| Feature / Metric | Kingrate Industrial Lamps | Standard Commercial Alternatives |
| End-of-Life UV Decay | Strictly ≤ 30% reduction at 9,000 hours | Often drops over 50% after 4,000 hours |
| Glass Material Type | High-transmittance pure quartz | Low-grade quartz or synthetic soft glass |
| Base Stabilization | High-temperature resistant G23 structure | Cheap plastic prone to thermal cracking |
| Ozone Output Control | Exact 253.7nm filament filtering, zero ozone generation | Unstable wavelengths creating chemical odors and ozone residues |
Standardized installation and maintenance are essential to guarantee the 9,000–13,000 hour long service life of PL-S Series H-Shaped UV Lamp PL-S13W. Please follow the protocols below:
Do not touch the quartz glass tube with bare hands. Skin oil residues will form hot spots during operation, cause quartz recrystallization and reduce UV transmittance. Please wear cotton gloves or hold the plastic G23 base for handling and installation.
For water treatment application scenarios, clean the matching quartz sleeve with alcohol or dilute citric acid every 3–6 months to remove mineral scale and sediment, avoiding UVC light blockage and reduced disinfection efficiency.
Tube end blackening is mainly caused by excessive cathode sputtering during frequent start-stop cycles or uneven filament heating. Kingrate adopts precise automated filament manufacturing technology, matching with dedicated electronic ballasts to output stable preheating current, which greatly reduces filament wear during startup and avoids premature blackening.
This PL-S Series H-Shaped UV Lamp PL-S13W supports both horizontal and vertical installation. For horizontal installation in water treatment chambers, ensure the G23 socket is tightly sealed with a waterproof quartz sleeve to prevent moisture from invading the contact pins and causing circuit failure.
This fault is mostly caused by mismatched electronic ballast parameters or loose G23 socket contact. PL-S Series H-Shaped UV Lamp PL-S13W require precise starting and operating currents. The use of underpowered or uncalibrated universal ballasts will lead to startup failure or trigger the ballast over-current protection mechanism.
