I took mine apart.
The bezel and head are glued but it only requires a little (lefty loosey) torq from a strap wrench.
I was able to remove the reflector by the lifting from opposite side of the emitter with the non sharpened part of safety razer and then carefully sliding it out. The reflector is made of plastic.
The emitter sitting on a thin aluminium mcpcb that is held in place with some thermal paste.
The driver looks to be press fit/glued. in fear of breaking things I didn’t not attempt to access the driver. 
A big mess of glue on the threads
On different note the included holder snapped in half while I was installing it. It was made of hard brittle plastic 
It’s a good thing I had this holder as backup.
