The lamp itself is small, rotates up and down easily (even with gloves on) and the switch on the left-side is easy to press for illumination. Green shows good power in the battery, red shows recharging or new batteries are required. Silva has created what it calls “customised light distribution”. This means there is a long reach spotlight and a close flood-light incorporated into the light beam. The aim is to give you better vision in the dark, with a longer and closer light distribution. As a user of the lamp, you don’t really know this is happening, except that you do enjoy great night vision.

How long it lasts will depend on the number of lumens and setting you use. Generally, the brighter the torch, the more power is required to keep it shining, so it will burn out sooner.

For many runners, brightness is the top consideration when finding the best running headlamp. However, it’s worth noting that brighter is not necessarily better. We believe there is such a thing as too bright, and we’ve found both too much light and too little light will cause eye strain. Additionally, too much light can blind your fellow trail users.

The Trail Runner H features what Silva describe as 'true lumens', meaning that they're measured by what they (and we) believe is the most reliable method available - the ANSI FL1 flashlight basic performance standard. This has become the industry standard and acts as a guarantee for more meaningful figures, in a market that can be guilty of some dubious and misleading claims in terms of both brightness and burn time.The reason being weight, comfort, price but most importantly the Hybrid battery combination and the flexibility it brings. Using the battery off the head is a real plus of the Trail Runner Free. Our lumen values are measured 30 seconds after switching the lamp on. We measure lumen according to the ANSI FL1 STANDARD.
