I got my TR-J12 5 x XM-L a few days ago, it was held up by Australia mail redirection because i moved house over the new year, as we all know now the king Kong's are a no go fitment wise out of the box.
I'm impressed with the build quality of the light it works well and is much brighter to my eyes playing out the back at night in the dark then the TR-3T6.
First impressions is its a nice looking light, looks much better then the TR host,s and its going to be a decent run time torch.
I have not been able to do to much testing except for current draw and a bit of running in the back yard.
