prices on 12 models— a sensor that monitors the level of ambient light. Used to automatically adjust the brightness of the flashlight to the environment — increase it in the dark when you need the brightest backlight and decrease it when the ambient light level rises. And when exposed to bright light, some of these models go into flashing mode — in order to warn the user and others that the flashlight is not turned off, and at the same time avoid unnecessary energy consumption.
