The centering ring looks okay, but the mcpcb is way off. It is glued down. It also looks like the positive wire is barely attached. This looks like a good opportunity to do some mods.
Get a brighter emitter with a copper mcpcb. Unlike most cheap copper mcpcb's, this one provides a better thermal path from the LED to the copper.

Do all this and your light may be twice as bright. For a little more oomph, you can get a new lens with anti reflective coating.

And since the top of that pill is wider, now you can use a 20mm copper mcpcb.
