Palmblaze K2 demountable ?

[Flymo]

Can you tell if it is possible to unscrew the head of a Palmblaze K2 for LED replacement.

The advertisement say's that the LED have a bulb life of 500 to 1000 hours, that is not much, IMHO...., so after that time is the LED replacable?

And does it accept 18650 batteries?

Thanks !

1: Yes, its glued on, just try hard (I put some tape around the head, then put 4 nails into the notches and clamped the whole head into a vise. Then use something to turn body)
But I have not yet been able to remove Led or optic

2: light output degrades (= gets weaker and weaker because of darkening of transparent emitter covering and degradation of the phosphorous). Will be more quick when emitter runs hotter than spec (and that light runs hot),
but it wont be burnt out like a halogen

3: no, and not enough material in body to bore out
