At full power, the Xera can spread intense light across the width of a carriageway, reaching beyond 15m.
Low mode doesn’t provide enough light to see by, but flash mode is strong and strobe-like. Optics for 14 and 16-degree beams are also provided, but there's no side visibility.
The light snaps into a bungee-secured clip, but its anodised aluminium body causes it to wobble, and the beam isn’t angled away from oncoming traffic. The power button can be too sensitive at times (press hard to turn on, press lightly to choose mode – or turn it off by accident!).
