A head torch with red light is a head torch that, in addition to the usual white light beam, produces red light. The advantage of a red beam is that you won't lose your night vision. Red LED lights often don't have a high light intensity. All because a red beam is not meant to reach far. A bright red beam could namely still make you lose your night vision.
A 5-lumen beam is more than enough to see something up close or to light up the path in front of you. When using red light making a distinction in colours is more difficult, but the contrast is bigger.
What do you need to pay attention to when purchasing a head torch with red light?
When purchasing a head torch with red light you need to pay attention to the way you switch between the white and red beam. Depending on what you will use the head torch for other things are important here. While hunting, for instance, it is important you don't accidentally turn on the white beam and scare off animals. In those situations you prefer a separate button to turn the red light on. If you easily want to switch between white and red light (when camping, for instance) a turning wheel is better.
