PHILIPS TUV PL-S 11W/2P | Germicidal UV-C | 253.7nm Disinfection | G23 2-Pin Base

Philips TUV PL-S 11W/2P (Order Code: 28565-0) is a specialized germicidal UV-C lamp designed for the professional disinfection of air, water, and surfaces. Emitting a concentrated peak of ultraviolet radiation at 253.7nm, this lamp effectively deactivates bacteria, viruses, and other microorganisms by disrupting their DNA. Featuring a compact PL-S 2-pin G23 base, it is an essential component for residential water purifiers, air sterilization units, and laboratory pond clarifiers.

Product Overview

Philips TUV lamps are world-renowned for their high-quality UV output and reliability. The TUV PL-S 11W series utilizes a special glass envelope that filters out the 185nm ozone-forming line, ensuring ozone-free operation while maximizing germicidal efficacy. Its 2-pin base includes a built-in starter, allowing for immediate ignition when paired with compatible electromagnetic ballasts. With a maintainable UV output that stays consistent throughout the life of the lamp, it provides long-term peace of mind for sensitive purification applications.

• Targeted Disinfection: Emits short-wave UV radiation with a peak at 253.7nm (UVC) for maximum germicidal effectiveness.
• Protective Coating: Internal lining ensures that the UV output remains stable over the entire 9,000-hour lifespan.
• Ozone-Free: Specialized glass prevents the formation of ozone, making it safe for indoor air purification systems and standard water treatment.
• Compact Form Factor: Short PL-S design is ideal for space-constrained residential water filters and portable sterilization devices.

Additional Information

The Philips 28565-0 is a critical maintenance component for maintaining sterile environments. To ensure continuous protection, it is recommended to replace germicidal lamps every 9,000 hours (approximately once per year), as the UV-C output diminishes over time even if the lamp remains lit. As a mercury-containing device, please follow local regulations regarding the proper disposal and recycling of fluorescent germicidal lamps.
