✅ Advantages
Relatively large light source for its compact size → softer shadows, nicer fall off vs a small modifier or bare LED head.
Square shape tends to give more even falloff in edges vs rectangular boxes, and reflections (catchlights) in eyes are square which some prefer.
Lightweight and collapsible, owns portability. Good for location or mobile setups.
Two diffusion strengths + grid give good control over contrast, softness, and light spill.
Bowens mount is very common, so you can use this with many different lights in the amaran/Aputure ecosystem.
⚠️ Considerations / Limitations
Because of depth (30 cm) plus front diffusion, there will be some light loss. If your COB light is not super powerful, you may need higher ISO or slower shutter / more power.
Larger modifier = more space required, especially if the light is close to subject; also needs sturdier stands, good mounting.
Setup still involves rods/insertion; not instant though it's fairly quick.
When using with very tight ceilings or in cramped setups, 45×45 may get in the way.
Portability is good, but it’s not as compact as softboxes that fold or umbrella‑type ones.
