Lumens are a measure of the total amount of visible light from a light source. The higher the lumen rating the “brighter” the light will appear.

The head torch is great, sits well on your head whilst running with the silicone against your skin and doesn't feel too tight or restrictive. Loved the customisable features for beam direction and height, perfect feature as it doesn't have any adjustment like typical head torches.
I've had the Knog 80 for a few years now and I love it. It didn't take long to decide to add the Bilby400 to my collection. Comfortable - perfect light. I use my lights for auto detailing and hammock camping. Did I say how comfortable this headlamp is?
So much good to say about this headlamp. from how it feels when wearing it to all the light options. the ease of getting the setting you want. top feature is that it is waterproof and rechargeable. no more carrying extra batteries backpacking.
Easy to use, great performance
This headlamp is great for running in the dark. It makes me easy to see and it makes my oth easy to see as well. The silicone strap is really nice too!
