Whew! Talk about even! This set up is a “pencil tube” wired to fire from a Dynalite pack. The only drawback is there is no modeling light or fan. The advantage is the travel kit is small and really light. You can pack four into the same space that one normal Dynalite head takes up. I just added a mini mount to the pencil and put it on a FourSquare Block with a 20 inch box. This is one of my regulars when I am using my Dynalite Kit. Happy shooting.
