Overview

The Aputure Light Box 4545 is a square softbox accessory designed to mount directly onto Aputure and Amaran COB LED video lights, including the Amaran COB 60X S, 60D S, Aputure 100D S, and 200X S series. Its purpose is straightforward: transform the concentrated, hard output of a COB light source into a broader, softer, and more even spread of illumination. With built dimensions of 45 x 45 x 30 cm, the square shape produces symmetrical catchlights and an even field of diffused light that works particularly well for interviews, product shots, and small-scale studio setups.

Portability is a key part of the design. The softbox collapses to a slim 48 x 26 x 50 cm profile that packs flat alongside other grip and lighting gear. Setup is quick, letting videographers and photographers spend less time rigging and more time shooting. The square form factor also stacks and stores more efficiently than octagonal or parabolic alternatives. For creators already working within the Aputure and Amaran ecosystem, the Light Box 4545 adds a practical and affordable diffusion option that scales from small COB fixtures up to 200W units without requiring additional adapters or mounting hardware.
