Almost all Fenix glued. Simple heating using heat gun will remove it easily. I opened 8 Fenix E05 with success.
Heat the head of the flashlight and measure the temp whenever possible. In my case I kept the temp below 120C because E05 uses TIR PMMA lens. LD10 seems to use reflector, I don’t know.
Then after you’re sure the entire head is evenly heated to ~100 - 120C use circlip plier or tweezer (there are two fastening holes) to turn the driver anti-clockwise. Don’t use brute force, the driver board is soft. If you can’t get it in the first try, try to heat it longer (not hotter). The thread locker need sometimes to soften, and when the whole head cools it will hardens back.
At it’s current level swapping to 219C or XPL won’t gain you measurable (by eyes) output, but you should get better runtime. XPG R5 has smaller die, swapping to XPL/XPL2 HD will give you almost almost twice bigger hotspot. Newer LEDs have lower voltage, this should give you slightly better regulated runtime. And the lumen/watt efficiency will be improved because lower output voltage is easier for the boost driver used in this light.
