QF35 23" Octa Softbox Kit

The QF35 kit delivers a 23-inch octagonal softbox with a silver interior, producing soft and even illumination for professional portraits and product photography. It is built for photographers using Quantum Instruments Qflash T, X, and TRIO series strobes who need reliable light shaping on location or in the studio.

Removable fabric grid and direct mount

A removable fabric grid narrows the beam and minimises spill, giving you precise directional control and added contrast for dramatic effects. The softbox attaches directly to compatible Qflash units and the Streaklight 360 without requiring a separate speed ring or umbrella shaft mount, simplifying setup and reducing gear bulk.

Carrying sleeve and compatibility check

The kit includes a convenient carrying sleeve for transport and storage, supporting mobile workflows such as weddings or outdoor shoots. Before ordering, confirm your flash unit is a Qflash T, X, or TRIO series model or a Streaklight 360, as the integrated mount will not fit other strobe systems or standard speed-ring configurations.
