3. Setup
Follow these steps to properly attach the Godox FLS10 Fresnel Lens to your compatible Godox Bowens Mount LED light:
- Ensure your Godox LED light is powered off and cooled down before attaching any accessories.
- Align the three mounting lugs on the rear of the FLS10 Fresnel Lens with the corresponding slots on the Bowens mount of your LED light.
- Insert the FLS10 into the Bowens mount.
- Rotate the FLS10 clockwise until it clicks securely into place. Ensure it is firmly seated and does not wobble.
- To remove, press the release lever on the Bowens mount of your LED light and rotate the FLS10 counter-clockwise until it detaches.

4. Operating Instructions
The FLS10 Fresnel Lens allows for easy adjustment of the beam angle to achieve desired lighting effects:
- Once the FLS10 is securely mounted on your LED light, power on the light.
- Locate the textured ring on the body of the FLS10. This ring is used for beam angle adjustment.
- To achieve a narrower, more focused beam (spot), rotate the ring in one direction (e.g., clockwise). The beam angle can be adjusted down to 10°.
- To achieve a wider, more diffused beam (flood), rotate the ring in the opposite direction (e.g., counter-clockwise). The beam angle can be adjusted up to 35°.
- Observe the light output and adjust the ring until the desired beam spread is achieved. Markings on the lens body indicate approximate beam angles (e.g., 10°, 15°, 20°, 35°).

5. Maintenance
Proper maintenance ensures the longevity and optimal performance of your FLS10 Fresnel Lens:
- Cleaning: Use a soft, lint-free cloth to gently wipe the lens surface. For stubborn smudges, a small amount of lens cleaning solution can be applied to the cloth (not directly to the lens). Avoid abrasive materials or harsh chemicals.
- Storage: When not in use, store the FLS10 in its included carry bag to protect it from dust, scratches, and impacts. Store in a cool, dry place.
- Handling: Always handle the lens by its body, avoiding direct contact with the optical surface to prevent fingerprints and smudges.
6. Troubleshooting
If you encounter issues with your FLS10 Fresnel Lens, consider the following:
- Lens not attaching securely: Ensure the mounting lugs are correctly aligned with the Bowens mount slots and that the lens is rotated fully until it clicks. Check for any obstructions in the mount.
- Beam adjustment is stiff: Check for any debris or foreign objects in the adjustment mechanism. If the issue persists, contact customer support. Do not force the adjustment ring.
- Reduced light output or uneven beam: Ensure the lens surface is clean and free from smudges or dust. Verify that the FLS10 is fully seated on the LED light.
