Aputure Light Dome III Softbox

Aputure Light Dome III is a 90 cm Bowens-mount circular softbox designed for fast-paced film, interview, portrait and commercial lighting setups. It keeps the familiar deep, round Light Dome format while introducing a redesigned quick-folding speed ring that collapses flatter for transport and opens more quickly on set. Its 32-sided front profile creates a very circular emitting surface, helping produce natural-looking reflections and round catchlights while maintaining the controlled character of a deep softbox.

90 cm circular source for portraits and interviews

The Light Dome III measures approximately 89 cm in diameter and 60 cm in depth when assembled. This gives it a large enough surface to create soft, flattering light on faces while remaining compact enough for everyday studio and location work. The deep shape helps keep the light more directional than a shallow softbox, which is useful when the key light needs to stay controlled around backgrounds and adjacent parts of the set.

Foldable speed ring for faster setup and transport

The major design change is the dual-sided quick-release mechanism and foldable speed ring. The modifier can collapse to approximately 88 × 18 × 5 cm, allowing it to pack much flatter than many conventional softboxes. Sixteen heavy-duty steel rods support the structure and help it maintain its shape during repeated setup and breakdown, making the Light Dome III particularly suitable for crews that move frequently between locations.

Two front diffusion strengths

The softbox includes interchangeable front diffusion fabrics rated at 1.5 and 2.5 stops. The lighter fabric retains more output and provides a slightly crisper result, while the denser option creates a softer and more diffused source. Unlike the Light Dome II, the Light Dome III is designed without a separate internal diffusion baffle, simplifying the internal construction and reducing the number of parts that need to be installed during setup.

40° grid for controlled soft light

A 40° fabric light-control grid can be attached to the front to reduce spill and keep the softened beam directed toward the subject. This is especially useful for interviews, portraits and multi-light scenes where a large soft source is required but the background needs to remain darker or independently controlled. The silver interior helps maintain output efficiency while the front diffusion shapes the final quality of the light.
