Nice I tired something like that, you going to want to bungee the 360 to the bracket. I've tighten the lock screw on the head to hold it on and it pulled the bulb out and the 360 dropped off after doing a shake test.
Thx, gonna do that then or something else like that.
Did you also try with umbrella holder on ? I think it can make it hard to get lose with that one on.
