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.
