P3X got a new design for better grip-ability. Serration are added for better grip.
R2 Lawman has a rotary knob on top allowing users to adjust type of operation they need. It can be used as a momentary light or a clicky type light. This is something that irked some users as they had to choose between the two when purchasing a light. Now it has been addressed in a very clever way.
Annihilator emits 5000 lumens.
P1R Peacekeeper emits 800/15 lumens. It also features a nice serration.
