The Doiron Design LS220N-SR1 lighting system is designed to combine the light output of two Nikon SB-800 Speedlights and direct it into an umbrella or softbox. A RadioPopper PX transmitter is attached with Velcro onto a Nikon SU-800 commander in the Master configuration and mounted on camera and one RadioPopper PX receiver slips into a receptacle on the LS220N-SR1 and provides full RF linked TTL control including high speed sync. There is no line of sight requirement between camera and off camera speedlights. A fiber optic splitter directs the signal from the RadioPopper PX receiver to both speedlights. One or two speedlights may be used as required.
The LS220N-SR1 supports the use of umbrellas up to 7 feet parabolic such as Westcott #4632, #4633 and #4634. An included spacer maintains the speedlights at the proper focal length for uniform light distribution with the Westcott parabolic umbrellas. Do
