Compare the Aputure Light Dome 40 and the STORM LightDome 150 to find the right softbox size for your shoot. Learn which light modifier fits your studio, location, or cinema work.
Quick answer
For compact, on-the-go lighting with the STORM 80c, choose the Light Dome 40; for large, ultra-soft diffusion on high-power fixtures like the STORM XT52, go with the STORM LightDome 150.
Size vs. portability trade-off
The main difference between these two softboxes is scale. The Light Dome 40 is a 40 cm mini softbox designed specifically for the Aputure STORM 80c, making it ideal for tight spaces or quick setups. In contrast, the STORM LightDome 150 spans 1.50 m and is built for high-power fixtures like the STORM XT52, delivering a much larger, softer light source.
Because the LightDome 150 uses a 16-rod architecture, it produces extremely even, hotspot-free light—critical for cinema, fashion, or product shots. The Light Dome 40 is simpler and faster to deploy, but its smaller surface area means less diffusion and a harder shadow falloff.
Mount compatibility matters
The Light Dome 40 uses a Mini ProLock mount that attaches directly to the STORM 80c. The STORM LightDome 150 uses an A-Mount and is optimized for Aputure Smart Mount fixtures. If you own multiple light heads, check compatibility before buying—these softboxes are not interchangeable between different mount systems.
Trade-offs at a glance
- Light Dome 40: 40 cm diameter, Mini ProLock mount, designed for STORM 80c. Compact and quick to set up, but limited diffusion area. Best for portability and small spaces.
- STORM LightDome 150: 1.50 m diameter, A-Mount, 16-rod architecture. Produces extremely soft, even light but requires more space and a compatible high-power fixture. Best for maximum light quality and large subjects.
- Mount compatibility: The two softboxes use different mounts (Mini ProLock vs A-Mount). They are not cross-compatible without adapters. Check your light head's mount before purchasing.
