Attention must be 3 R20 batteries, not 2! Perfect lamp for lighting a cellar powerful light very well distributed and warmer color than traditional LED (Comparisons with a recent model of another brand) I have not found a strobe function (no need for me), against 1 by pressing the button gives maximum power, another pressure off the lamp. For the half-power, 2 pressure on pou turn, another press to turn off. This is very convenient to use, especially as the half power is already comfortable. Otherwise, little bulky lamp easy to squeeze.
