At that price you can buy eyes closed, it gives a really powerful light. I have a Fenix TK15 lamp that does not weight! Thanks to the focus we can have a small point which illuminates several hundred meters (I tested) or if the beam is expanded to a diameter of 2.50m so it possible to properly illuminate a close range. Three lighting modes (100%, 50%, strobe) that we change by pressing lightly on the push button. The light always comes in 100% mode when léteint then that the on again. Possibility to put 3 rechargeable AAA batteries or 2 CR 123 and 123A rechargeable batteries or 1 rechargeable 18650 battery. Delivery from GB who has 11 days for the Paris region.
