the head of the torch has its own focusing adjustment, which aint very good...those torch's are designed to use the t20's original focusing threads (the central bit you refer to) but it shouldn't screw off completely
what you should do is screw the central bit as far out as it will go (so the torch is at it longest) then fine tune with the head adjustment until its as you like it, you shouldn't need to touch the head again after that. i don't like to see the lines of the led. some people do
incase you were wondering. i have no involment in ian's business. all it is is that head and torch combo was originally my baby and ian has co-opted it to sell and put his own stamp on
also i cant comment much on the visible light versions as my own are all infra red
