Use the MagicArm set with the Walimex Aptaris cage and an LED head light. The arm can be well fixed to the cage and you can choose between the attachment to the hot shoe or a 1/4 "threaded select (a 1/4" thread for the LED to fasten light and on the other side either threaded or hotshoe attachment). For an LED head light the length of the arm is very good and compact for an external monitor, the arm but too short and you should choose the longer variant.
