Regulated lights emit over their entire burn time a constant amount of light due to an electronic regulation system. Is the battery (pack) empty, can’t the same amount of light be emitted anymore, than the light will automatically turn off. Because you don’t want to be surprised, these lamps feature a battery indicator.
