1. Introduction
This manual provides essential information for the safe and effective use of the Philips 210641 18-watt PL-L TUV Germicidal Light Bulb. This compact UVC lamp is designed for disinfection purposes in residential water and air treatment units.
The Philips TUV PL-L lamp utilizes short-wave UV radiation (UVC) with a peak at 253.7 nm to deactivate bacteria, viruses, and other microorganisms.

4.1. General Installation Guidelines
- Power Disconnection: Before attempting any installation or replacement, ensure the power supply to the UVC unit is completely disconnected.
- Handling the Lamp: Handle the lamp by its ceramic base or ends. Avoid touching the glass portion directly with bare hands, as oils from the skin can create hot spots and reduce lamp life. If touched, clean with a lint-free cloth and rubbing alcohol.
- Base Type: This lamp features a 2G11, 4-pin base. Ensure your UVC unit's socket is compatible with this base type.

5. Operation
The Philips 210641 lamp operates by emitting UVC radiation to disinfect water or air as it passes through the UVC unit. Once installed and powered, the lamp will illuminate, and the UVC unit will begin its disinfection process.
- Automatic Operation: In most residential UVC systems, the lamp operates automatically when the system is active (e.g., water flowing, air circulating).
- Indicator Lights: Many UVC units include indicator lights to confirm lamp operation or signal when a lamp replacement is due. Consult your UVC unit's manual for specific indicator meanings.
- No Visible Light: While the lamp emits UVC radiation, the visible light output is minimal. Do not rely on visible light as an indicator of proper UVC output.
6. Maintenance
Regular maintenance ensures the continued effectiveness of your UVC disinfection system.
6.1. Lamp Replacement
- Lifespan: The Philips 210641 lamp has a rated average operating life of 9000 hours. For optimal disinfection performance, it is recommended to replace the lamp annually, even if it still appears to be functioning. UVC output diminishes over time, even if the lamp is still glowing.
- Replacement Procedure:
- Disconnect power to the UVC unit.
- Allow the lamp to cool down if it has been recently operating.
- Carefully remove the old lamp by gently pulling it straight out from the socket.
- Dispose of the old lamp responsibly according to local regulations for mercury-containing products.
- Install the new Philips 210641 lamp following the "Setup and Installation" guidelines.
- Reconnect power and verify operation.
6.2. Cleaning
- Quartz Sleeve (if applicable): If your UVC unit uses a quartz sleeve around the lamp, it may require periodic cleaning to remove mineral deposits or debris that can block UVC transmission. Refer to your UVC unit's manual for cleaning instructions. Always disconnect power before cleaning.
- Lamp Glass: If the lamp glass itself becomes dirty (e.g., from accidental touching), clean it with a lint-free cloth moistened with rubbing alcohol. Ensure the lamp is completely dry before reinstallation or operation.
