I have one and it looks the same, but I'm not sure if it's the same. I bought it here in Spain.
It has 3 Leds and the switch works 1 led, off, 3 leds, off and so on.
1 Minute crank = 1 hour and 20 minutes light with one led.
Inside is a LiIon button cell, so after a few years the batt must be changed.
Best regards
