Just a standard internal thread heatsink there, holes for Tri leds on the final version.
Sounds good for the switches then, I will get the plans altered for the red thumbscrew.
We can now think about the recharge socket going in the pommel, will have a word with the FR guys about a speaker holder combo, this would work as the end op the pommel will unscrew.
I am also having a few doubts about the detailing next to the led, for the Plo I have it as a 3mm led in bezel, the Luminara looks like two.
Anyone got more info on these???
