The Profoto RFi Speedlight Speedring allows you to use an RFi softbox with speedlights. You can also mount not just one, but two speedlights on a bracket. Each speedlight can be adjusted in the softbox, allowing you to create even light with no hotspots. The RFi Speedring also comes with an attachment for Profoto Air Remotes.
The RFi Speedlight Speedring is designed so that the RFi softboxes can be rotated 360°, allowing the photographer to adjust and shape the light on the fly. The color codes make the softboxes easy to assemble and disassemble, and all speedring adaptors are robust and painted with heat resistant lacquer.
