I was surprised by the luminous power of the torch, especially as it works with one AA battery only. It is small, compact and fits nicely in the hand. The zoom allows for a large surface when light is near. The brightness makes really good view over a wide area. If it is greater, it can use the zoom and focus the beam. In more concentrated, we do not see a light round but the square of the diode, which is surprising when you first use. Given its price, its lighting power and the use of a single AA battery, I have ordered several others to leave in the car, as a backup torch and offer.
