It depends on what the dedolight connector is. If it's a standard 5/8 ("baby", like a c-stand arm or pin) there's one made that's a simple 5/8 post. I have a couple older 2" fresnels with 1/4" mounts, no superclamp stud for that, you'd need a 5/8 to 1/4 post adapter (not threaded). If it has a female threaded scket (like some consumer gear or hotshoe mount stuff) of 1/4-20 or 5/8-16, there are studs that have male threaded posts.
