ULANZI 18ft Parabolic Softbox Quick Release - Portable Bowens Softbox

In this review of the ULANZI 18' parabolic softbox, the bottom line is simple: it is a compact, travel-friendly modifier that gives a soft, controlled beam for run-and-gun interviews and small studio setups. The reviewer found the original quick release structure genuinely fast to use, making on-location swaps painless, and the combination of inner and outer diffusers plus the included grid delivers a versatile range of softening and direction control. This makes the softbox a sensible choice for photographers and videographers who need portability without sacrificing light quality.

Key Features

• Quick release installation: The original quick release structure allows the softbox to be installed or removed in about 15 seconds, saving time on location changes.
• Portable construction: The foldable design and included carrying bag keep the unit lightweight and travel-ready at roughly 709-790g depending on measurement cited.
• Adjustable light shaping: Support for one to three layers of diffusion (inner baffle, front diffuser and grid) provides options from wide soft fill to a tightened beam for controlled highlights.
• Bowens mount compatibility: The included Bowens speedring adapter works with many mainstream strobe and LED heads with Bowens mounts for broad compatibility.
• Durable frame: Stainless steel brackets and an aluminum alloy speedring give the softbox enough toughness to resist deformation during repeated use.
• Reversible deflector: The deflector design reduces the center hot spot and improves evenness across the parabolic surface.

Who It's For

This softbox suits portrait and interview shooters who move between locations and need a lightweight modifier that still yields professional-looking soft light. It is also useful as a hair or rim light when paired with compact Bowens-mount LEDs or small strobe heads, offering tighter beam control with the honeycomb grid.

Photographers who require very large soft fields or those using non-Bowens proprietary mounts should look elsewhere; compatibility reports are mixed for some models, so double-check your fixture fits the included speedring adapter before purchasing.
