2. Important Safety Information
WARNING: Ultraviolet (UV) light can cause damage to eyes and skin. Always wear protective gear, including UV-blocking eyewear and gloves, when handling or working near an active UV bulb. Never look directly at the operating UV light.
- Disconnect power to the UV system before installation, removal, or maintenance.
- Avoid touching the glass part of the bulb with bare hands. Oils from your skin can create hot spots, reducing bulb life and efficiency. Use clean gloves or a soft cloth.
- Dispose of used UV bulbs according to local regulations for hazardous waste, as they may contain mercury.
- Ensure the UV system housing is intact and properly sealed before operating to prevent UV light leakage.

3. Installation Instructions
This UV bulb is intended for use with compatible devices and systems only. Refer to the instruction manual that came with your original equipment for specific installation steps. The following are general guidelines:
- Power Disconnection: Ensure the UV system is completely disconnected from its power source before beginning installation.
- Access the Bulb Housing: Carefully open the UV system's housing to access the old UV bulb. This may involve unscrewing covers or releasing clips.
- Remove Old Bulb: Wearing gloves, gently grasp the old bulb by its ceramic or plastic base and pull it straight out from the socket. Avoid twisting or bending.
- Install New Bulb: Align the square 2-pin base of the new LSE Lighting UV bulb with the socket. Gently push the bulb straight into the socket until it is fully seated. Do not force it.
- Secure Housing: Close and secure the UV system's housing, ensuring all seals and covers are properly reinstalled.
- Reconnect Power: Once the bulb is securely installed and the system is reassembled, reconnect the power.
If you are unsure about any step, consult a qualified technician or the original equipment manufacturer's manual.
4. Operating Your UV System
After proper installation, the LSE Lighting 9W UV Bulb will begin to emit UVC light when the compatible system is powered on. The UV light works to sterilize water or air passing through the system, depending on the application.
- Ensure the system is operating within its recommended parameters as specified by the original equipment manufacturer.
- Do not operate the UV system if the bulb housing is damaged or if there is any visible UV light leakage.
- Regularly check the system for proper function, though direct observation of the UV light is not recommended due to safety concerns.
5. Maintenance and Replacement
The LSE Lighting 9W UV Bulb has a rated service life of 12,000 hours of continuous operation. For optimal performance and effective sterilization, it is recommended to replace the UV bulb annually, even if it appears to be working. Over time, the UVC output diminishes, reducing its effectiveness.

When replacing the bulb, always follow the safety precautions outlined in Section 2. Additionally:
- Inspect the quartz sleeve (if applicable to your system) for any deposits or damage. Clean the quartz sleeve with a soft cloth and a mild cleaning solution if necessary, ensuring it is completely dry before reassembly.
- Do not use abrasive cleaners or materials that could scratch the quartz sleeve or bulb.
