To maximize disinfection throughput without increasing equipment footprints, buying a wholesale High Output 4P UV Lamp from professional China manufacturers is an efficient strategy. Kingrate uses an ISO9001-certified automated production line to manufacture these high-output lamps, applying an optimized gas-fill ratio that lowers energy consumption while maintaining a 9,000-hour service life. The single-ended 4-pin layout makes it easy to install liquid-tight seals, helping global environmental systems integrators simplify their product designs.
Single-Ended 4-Pin Integrated Wiring Design: Both cathode circuits are concentrated on a single base, realizing one-sided installation and replacement. It eliminates external return cables, avoids light shielding and wiring chaos in narrow equipment cabins, and greatly improves maintenance efficiency of closed-chamber sterilization systems.
High-Current Density Reinforced Filament: Different from the 425mA conventional current of standard lamps, this High Output 4P UV Lamp supports 800mA-1.2A high-current operation. Equipped with double-wound heavy-duty tungsten cathode and high-density emissive powder, it resists high-current electrical stress, avoids burnout, and achieves nearly double UVC output of lamps with the same length.
High-Strength Ceramic Base: The vitrified high-density ceramic base is resistant to UVC radiation aging, ozone corrosion and high-temperature thermal stress, maintaining stable insulation and structural integrity throughout the service life.
• Terminal Connector Type: Single-Ended 4-Pin Base (Ceramic Construction)
• Operational Wattage Spectrum: 18W to 150W configurations
• Target Driving Current Density: 800mA to 1.2A high-intensity plasma arc
• Peak Germicidal Output Line: 253.7nm (Pure Ozone-Free C-Band UV)
• Base Thermal Threshold: Engineered to operate reliably up to 250°C without structural degradation
• Commercial Kitchen Hood Grease Control: High Output 4P UV Lamp mounted inside high-volume exhaust hoods to break down airborne oils and grease compounds, reducing duct fire hazards.
• Pharmaceutical Formulation Water Loops: Installed in recirculation storage loops to sanitize pure process water without introducing chemical additives.
• High-Capacity Air Handling Units (AHU): Arranged across cooling coil banks in commercial buildings to destroy mold spores and airborne pathogens.
• Heavy-Duty Ceramic Bases: Low-grade manufacturers often use cheap plastic or low-grade resin connector bases that become brittle and crack under continuous UVC exposure. Kingrate High Output 4P UV Lamp uses high-density, vitrified ceramic bases that are completely immune to UVC degradation and thermal stress.
• Reinforced Filament Structure: Running higher electrical currents (800mA+) can quickly burn out standard filaments. Kingrate integrates double-wound tungsten cathodes coated with an extra layer of emissive carbonate powder, allowing them to withstand high-current operation without premature failure.
Given the long, single-ended profile of these lamps, they are highly vulnerable to bending stress during transit. Kingrate packs each lamp inside an individual, rigid cardboard sleeve, which is then secured within a multi-layered outer export carton. For bulk sea or air freight shipments, cartons are stacked onto reinforced pallets and wrapped in a thick layer of protective stretch film to ensure they arrive undamaged.
A: Because this High Output 4P UV Lamp operates at a higher current density (800mA+), standard ballasts designed for 425mA lamps cannot deliver sufficient current to sustain the high-intensity discharge arc. Using an incorrect or underpowered ballast will cause uneven lamp ignition, flickering, and rapid degradation of the cathode filaments.
A: The 4-pin base is molded from a high-density, vitrified ceramic compound that is completely immune to UVC degradation, ozone oxidation, and high thermal stress. Plastic bases can degrade and crack over time under intense radiation, but our ceramic bases maintain their insulation properties and structural integrity throughout the lamp's lifecycle.
A: This High Output 4P UV Lamp is designed to operate efficiently in both horizontal and vertical positions. However, when mounting vertically, we recommend positioning the 4-pin ceramic base at the top of the assembly to minimize gravity-induced thermal stress on the heavy-duty filaments during continuous operation.
