The ones from the Lightning are the Behotec C50's. You can get them along with several different sizes/styles of struts from Peter at Altecare:

He's been great to deal with for me and the Behotec gear for the Flash (C36/2) have been great - once I modified them for 8mm pins (the C50's already use 8mm pins, I believe).
