Recently I picked up a new head torch to help with the dark early morning runs. Some paths that I use have no lighting and can be dangerous, like this week when I avoided a 30cm dugite. I had been using a Petzl head torch for about 6 years and had been very happy with it but it was not holding a charge and was pretty dirty, so I picked up the equivalent model as a bit of a treat.
It is super bright, with its maximum 900 lumen led and auto adjust brightness based on ambient light. I find that I use the lowest setting mostly and sometimes the middle one. I could imagine if I was trail running the high setting would be very helpful.
It is very easy to use, there is one button that rotates through low, medium, high and off. You can switch between auto adjusted to fixed brightness by holding the same button down for a few seconds. I like auto adjust because it means that if a car is coming the other way, I know I’m not affecting the driver.
The battery is great, especially on the low setting.
It is really comfortable to wear, which is important when heading out for hour long runs.
The Swift RL is highly recommended.
