K1-L 13 Lumens, 15m, IPX4 Uses 4 AG3 - This is a flashlight to be admired! Although it only weighs a few grams and is hardly any bigger than a matchstick, it is far brighter than you would suspect, given its size. The luminous ring gives the flashlight an additional special feature. It is also practical that you can be seen within a 270?? angle.
