Learn how to assemble and attach the Godox QR-P120 quick release parabolic softbox to a Bowens mount studio light. Step-by-step guide with common mistakes to avoid.
Quick Answer
Assemble the Godox QR-P120 by unfolding the parabolic frame, attaching the inner and outer diffusers, then mounting it onto a Bowens-compatible studio flash using the quick release mechanism.
Why Parabolic Softboxes Are Different
The Godox QR-P120's parabolic shape produces a more focused, wrap-around light compared to flat softboxes. This design gives you a softer falloff with more directional control, ideal for portraiture. The 120cm size provides a large light source that still fits in a standard studio setup.
One trade-off: the deeper profile can be harder to position in tight spaces. Plan your light placement before fully assembling the softbox.
Step-by-Step Setup Guide
- Unfold and Shape the Frame: Remove the softbox from its carry bag. Hold the central hub and gently pull the rods outward until the parabolic shape locks into place. You should hear a click at each rod joint. Common mistake: forcing the rods too quickly can bend them. Work slowly and evenly around the frame.
- Attach the Inner Diffuser: Locate the smaller, inner diffuser panel. Hook its corner loops onto the corresponding tabs inside the softbox frame. Start with one corner, then stretch and attach the opposite corner to avoid sagging. Checkpoint: the inner diffuser should sit taut with no wrinkles, as wrinkles create uneven light patterns.
- Attach the Outer Diffuser: Place the larger outer diffuser over the front opening. Use the Velcro strips along the rim to secure it to the frame. Ensure the diffuser is centered and pulled tight. Common mistake: overlapping Velcro strips can leave gaps that cause light leaks. Align each strip carefully.
- Mount to the Studio Light: Hold the softbox by its speed ring (the metal or plastic ring at the back). Align the ring's tabs with the slots on your Bowens mount light. Push the ring onto the light and turn it clockwise until it locks. Checkpoint: confirm the locking pin or lever engages fully. A loose mount can cause the softbox to fall during a shoot.
- Adjust and Test the Light: Power on your studio flash at a low setting. Point the softbox at a white wall or subject and check for even illumination. If you see hot spots, adjust the diffusers or the distance from the light head. Common mistake: assuming the softbox is ready without testing. Always do a quick test shot to catch issues early.
