Answering both questions about the Amutorch VG10 (old version):
a) The driver is 23mm diameter. The “pill” diameter (that is not a pill, it is the head the flashlight) is about 22.5mm. Thanks for referring the thread, Lux, as I forgot to upload more photos to clarify that. Will do it after in some minutes!!
b) The flashlight is moddable, but some things must be take into account, namely the tail and the clicky switch, as it is “shaped” for a big Forward Switch. This said:
1) the driver can be replaced easily, but its diameter must be taken into account. I don’t know if a 22mm driver will fit completely well, but with some “fix” it will fit!
2) the emitter/MCPCB can be easily replaced, you have access through the head to de-solder the wires. I am thinking about that on mine, I’m just deciding if I will opt for a “throwy” LED (the reflector produces a nice throwy beam), or a quad :smiling_imp:
Here are some photos (I will add them on the my review thread as well).
