Damn wish I’d seen the Alpha sooner. 
Do you have the AA extender for the Nitecore? Package deal for the Nitecore and Jetbeam?
No extender for the Nitecore. PM sent about package deal.
I used a piece of grey 3M grip tape pressed into the bezel for extra grip to help unscrew the bezel. The bezel was not glued so was fairly easy to remove. With the bezel off the lens can then just fall out. Then insert something under the edge of the o-ring to remove it. With that out the reflector should fall out.
Now comes the tough part:
- The SRT3 has a tiny aluminum star with an aux LED board on top of it.
- The aux LED board has 4 miniscule wires that connect to bondpads on the underside of the board. Even worse, the wires did not appear long enough to get at those bondpads. I quickly concluded that if I desoldered the aux board I’d never be able to resolder it.
- I desoldered the driver wires from the star. Then I tilted up the aux board and lifted and twisted the star around it until I could get it out of the light for the reflow. I did not attempt to desolder the aux board.
Thank you for the info!
