i have some uses for the strobe mode (only on my Jetbeam lights and Akoray K106 3 mode as i can program the frequency of the strobe):
1. Slow strobe for cycling
2. Beacon (1 blink every few seconds) when night fishing on the shoreline, the light is clipped to my pack so we can locate where we put our stuff as we move up and down the beach to cast.
3. Faster strobe to signal our location to friends looking for us on the beach (of course i could just use the forward clicky on my G2 with R5 but where's the fun in that?)
4. Fastest strobe just for fun
That being said, strobe should be hidden and only used when i want it and the frequency of it being programmable would be a good touch, cannot imagine cycling with a 14-15 hZ strobe causing fits and accidents as i move down the road / track.
