Profoto 100504 RFi Speedring Adapter Bowens Mount

The Profoto 100504 RFi Speedring Adapter bridges the gap between Profoto's popular RFi softbox line and the widely used Bowens bayonet mount system. If you shoot with Bowens-compatible strobes from brands like Godox, Interfit, or Calumet but want to take advantage of Profoto's well-engineered light shaping tools, this adapter makes that possible without replacing your existing lights. The twist-lock bayonet mechanism provides a solid, rattle-free connection that holds up during long shoots and frequent repositioning.

Setup is streamlined by Profoto's color-coded rod system. Each softbox rod is marked with a color that corresponds to a matching socket on the speedring, so you can assemble any RFi modifier — whether square, rectangular, or octagonal — quickly and correctly every time. The adapter is built from durable metal and maintains a low profile, keeping your softbox close to the light source for efficient light output. For studios already invested in Bowens-mount equipment, this speedring is a practical way to access Profoto's modifier ecosystem without a full system changeover.
