Thanks for the concern, Tom E! Very sorry to hijack your thread, elnino.
I’m not in USA so it’s not possible to send it over.
I managed to screw this thing out, tested for continuity with multimeter on the two metal wires on the black “CREE XML” plate, and it cannot conduct, so I suspect the driver (which is hidden inside) is damaged, but I’m not very sure.
But I couldn’t take the East-092 driver out. Perhaps I try with a flat-end screwdriver to leverage it out?
However if there’s a already-assembled working pill like this to purchase, it’ll be great!! I just need to unscrew this pill and replace it with a new one. Save the trouble sending it back to Tmart, or waiting for replacement, or any modding trouble (I don’t know how to).
