It differs from the other two in that it is activated by a tail switch and then the modes are accessed by two buttons on the side up by the head.

I played around with all the modes to get familiar with them. Pretty straight forward. Goes from a 1 lumen low-low to a 920 lumen turbo (on an 18350 battery. About half that on a CR123 which is still very bright). Has the blinky functions of strobe, beacon and SOS which I think are important in an EDC prep light. Also has Red continuous, Red to indicate battery charge and Red that goes off every three seconds or so to indicated it's location. In that mode it lasts 6 months according to the instructions.
Took the dog for a walk just now and since it's dark it gave me a good opportunity to test it out. The turbo is definitely bright! Lit up the woods really well and for a decent distance as well. I found that the low setting (between low-low and medium) at 70 lumens was bright enough for walking through dark areas and seeing the sidewalk. Rated for 5 hours on that setting and I think that will be my go-to setting. Since it has memory it will come on in low when I click the tail cap.
While I certainly like high and turbo, I like run time even better. 5 hours at 70 lumens is going to be good for most needs like walks, power outages etc.
