I was down the local hardware and happened to spot these little gems. $8 with a spare set of batteries.
On a purely subjective test, i.e. shining them in my yard, it is slightly less bright than the Nano, but would do just as well to light up a dark path or as a personal beacon.
It beats the hell out of the LED in my Climber-Lite (Spartan-Lite plus scissors) and except for run time would top a Mini-Mag
I grabbed two and with the mini carabina included, the black one is going on my keyring and the red one just became permanent partner for my red/black Dime.
