I just received this light today and discovered an undocumented mode that's probably worth adding to the review text. There's a 5th beacon mode (Location beacon). If you turn off the light in L2 and then triple-click to activate the beacon modes, the .2hz low mode will then become a location beacon. Turning the light off when in L1 and then doing the same will revert it back to its default mid-output .2hz mode.
I expect this to be useful to anyone (like me) who has inadvertently gotten it into this mode and doesn't know how to get it back to normal, or to someone wanting to use the location beacon function. By the looks of the specs, it could probably be left on indefinitely without any significant impact to the battery.
