Pro X Lightbanks feature recessed front screen that is removable, while Pro II lightbanks have a flush, sewn-in front screen.
As a result, Pro X lightbanks with the recessed front have a bit more dramatic falloff or edge transfer and less spill compared to a Pro II lightbank.
While both lightbanks have removable inner baffles, the Pro II front screen is not user-replaceable.
Many users of the Pro X opt to purchase optional diffusion screens for their lightbank, available in 1/2 Grid Cloth Diffusion and 1/4 Grid Cloth Diffusion.
