5. Operating Instructions
Once the flash tube is correctly installed, you can operate your Godox K150 or K180 strobe unit as usual. Refer to your strobe unit's main instruction manual for detailed operating procedures, power adjustments, and synchronization settings.

6. Maintenance
Proper maintenance will help prolong the life of your flash tube and ensure consistent performance.
- Cleaning: If the flash tube becomes dirty, gently wipe it with a clean, soft, lint-free cloth. For stubborn marks, a small amount of isopropyl alcohol can be used, ensuring it evaporates completely before use.
- Handling: Always handle the flash tube by its base or ceramic parts, avoiding direct contact with the glass.
- Storage: When not in use, store the flash tube in its original protective packaging or a safe, dry place away from dust and extreme temperatures.
