Thanks for bringing that up. You are correct, the New Model will fit a Protected 18350, the Original will not, it only fits the UnProtected 18350
.
what Im getting from the poll, is that over 75% of participants want whatever Clemence has to offer, and I agree 100% 
Clemences new version RRT-01 Hight CRI offerings, and details about what LEDs and optics will be used, will be posted in a separate thread.
Vinh also is building new version RRT-01 with various LEDs.
.
Im thinking about buying 10 Original Model RRT-01 to be modded to High CRI N219b and made available for purchase. They have short pocket clips. :-). Please PM me if any of you would like to know more details.

If anyone wants to buy an Original Model RRT-01 in stock form, you can get them from the link in this post:
