Smallest P60 Host

Finally I got part of the Host open, the bit that holds the reflector to the head. Some sort of red glue was used.

Cannot get the head open from the body. There is one of two things I can do. One use it as a p60 host but the bezel does not screw down all the way.

Less than 10cm tall

Two Install a XPG R5 20mm star and a 1 Amp 19-20mm Driver. Or should I go with XML?

Look at the pics the round metal ring is the pill.
