About this deal
Removable and replaceable battery (also sold separately) makes it possible to switch out the battery during use I tried this and I still got confused. Perhaps I am a bit dim or perhaps I need to get more used to the differences but in the end I just switched the beam to standard and got on with my run. I should point out I have used the head torch more than 20 times and in different locations and situations.

The reactive lighting sensor is the circle to the right of the main light 3. Petzl Swift RL headtorch Reactive Lighting Technology
Conclusion
Minimum burn time of 7 hours in REACTIVE LIGHTING® mode (STANDARD level), built to power through long activities The beams are virtually the same on both modes, so once it’s switched on, you don’t really know which you’re in. Another odd thing happened on a chilly evening. My breath appeared to cause the beam to dim, or was it the mist? Anyway, something caused the light to dim, which was annoying at best and dangerous at worst. I don’t want to have a dimmer beam when it is cold and I am breathing out, or in mist/rain/snow.

Visual comfort enhanced by the mixed beam, which provides high-performance lighting for outdoor activities: proximity vision, movement and distance vision If you are running or walking on your own there are far fewer variables for the reactive technology to be influenced by. Even so, I found that the beam didn’t stay as bright as I would wish it to be to be able to see my way ahead. I am wondering if this is because of my myopia. I know I prefer a brighter beam and perhaps I require a brighter light to run by than the reactive beam offers me.Ergonomic and adjustable headband provides the ideal fit, with split construction (Petzl patent); the headband can also be detached and washed or replaced.
