3. Setup
Setting up the Godox Parabolic Deep Reflective Umbrella is a quick process, typically taking 2-3 seconds.
- Unpack: Remove the umbrella from its storage bag.
- Open Umbrella: Hold the umbrella by the shaft and push the mechanism until it locks into place, similar to opening a standard umbrella. The 16 fiberglass ribs will extend to form the parabolic shape.
- Mount: Insert the umbrella shaft into a compatible light stand bracket or light head. Secure it firmly.
- Attach Diffuser (Optional): If softer, more diffused light is desired, attach the white diffuser cover over the front of the umbrella. The diffuser typically has an elastic band or drawstring to secure it around the rim of the umbrella.

4. Operating Instructions
The Godox Parabolic Deep Reflective Umbrella is versatile for various lighting scenarios. Its deep parabolic shape allows for precise light control, while the white interior provides soft, even illumination.
4.1 Light Shaping
- Direct Reflection: Without the diffuser, the white reflective interior provides a broad, soft light source with a slight punch, ideal for portraits, product photography, and group shots. The deep shape helps to control light spill.
- Diffused Light: When the white diffuser cover is attached, the light becomes softer and more uniform, reducing harsh shadows and creating a flattering light for subjects. This setup effectively transforms the umbrella into a large softbox.

5. Maintenance
Proper maintenance ensures the longevity and performance of your reflective umbrella.
- Cleaning: Gently wipe the reflective interior and exterior fabric with a soft, damp cloth. Avoid abrasive cleaners or harsh chemicals that could damage the material.
- Storage: After use, allow the umbrella to dry completely before folding and storing it in its provided carry pouch. This prevents mold and mildew.
- Handling: Avoid sharp objects that could puncture or tear the fabric. Handle the ribs carefully to prevent bending or breaking.

6. Troubleshooting
If you encounter issues with your Godox Parabolic Deep Reflective Umbrella, consider the following:
- Umbrella not opening/closing smoothly: Check for any obstructions in the mechanism or bent ribs. Ensure the release button is fully pressed when closing.
- Uneven light output: Verify that your light source is centered within the umbrella. If using the diffuser, ensure it is evenly stretched across the umbrella's opening.
- Light spill: Adjust the position of the light source within the umbrella or the distance of the umbrella from your subject to control light spread.
