Just got my Nitecore Defender in today and just a few minutes ago was fooling with it and my old Fenix L2T CR123.

Seems that the L2T head will fit the Nitecore body, but the Nitecore head just doesn't want to thread onto the CR123 L2T body I have.

I need to dig out the original 2AA L2T body and try it with the Nitecore head.

Might have some interesting Lego combinations with the old Fenixs and the Nitecore.

Shame I gotta run and hit the road for Christmas Eve dinner. At least I get to show off the Nitecore!!
