Lamp fully recommend to anyone looking for a super powerful flashlight! lighting 850 lumens is amazing for a lamp of this size. 5 brightness levels enable adaptation necessary, the Strombo mode provides a first level of self-defense. 2 The only negatives I found him are: - No SOS mode (never needed for now but ...) - The lamp does not make sense lighting up (the back button is a bit too rounded for her to balance).
