Product Information

Full details

The Aputure INFINIBAR PB3 Softbox is designed for filmmakers and lighting technicians who require professional-grade diffusion for their 1-foot INFINIBAR LED bars. It provides a soft, flattering light quality perfect for product photography or close-up portraiture while maintaining a highly portable, lightweight form factor. The primary caveat is that it is exclusively compatible with the INFINIBAR PB3 model and cannot be used with other LED fixtures.

FAQs

Can I use this softbox with the INFINIBAR PB6 or PB12?

No, this softbox is specifically sized for the 1-foot PB3 and will not fit other INFINIBAR models.

Is the front diffusion panel removable?

Yes, the diffusion material can be detached, though it is recommended to keep it installed to ensure the intended light quality.

Does the softbox affect the color temperature of the LED?

The diffusion fabric is color-neutral and will not shift the Kelvin rating of your INFINIBAR PB3.

How should I clean the fabric?

Use a dry or slightly damp lint-free cloth to wipe the exterior; avoid abrasive detergents that could damage the reflective lining.

Can I mount the softbox to a tripod while it's on the light?

Yes, since the softbox is lightweight, it does not significantly shift the center of gravity, allowing for standard tripod mounting.

Troubleshooting

Softbox does not fit flush against the light

Ensure the PB3 is properly aligned within the frame and that no obstructions are caught between the frame and the fixture.

Light spill is too high despite using the grid

Verify that the 45-degree grid is snapped securely into the front of the softbox and that the diffusion layer is pulled taut.

Pros and Cons

Pros

Extremely fast, tool-less assembly
Lightweight and compact for travel
Includes a high-quality 45-degree grid
Excellent diffusion for close-range lighting

Cons

Compatible only with the INFINIBAR PB3
Reduces total raw output intensity

Setup, Compatibility & Care

Setup is intuitive: align the softbox housing with the mounting points of your PB3 bar and secure the fasteners. Ensure the interior material is free of dust before attaching the front diffusion panel to maintain light clarity. When finished, collapse the softbox by following the reverse steps; always store it in a cool, dry place to prevent the fabric or reflective lining from degrading. This product is intended for indoor or controlled outdoor use and should be protected from high winds or heavy rain.
