The Lowdown: Gloworm X2

There is a light company from New Zealand called Gloworm. They make extremely well-crafted lights that come in three configurations, the X1, X2 and XS. They are all honest with their lumen output claims and have very compact configurations for bar or helmet use. This year, they are including optional wide beam optics in the package to give the rider the choice of beams that suits their riding. The model reviewed here is the middle X2 one with two LEDs.

Gloworm is an Mtbr forum legend with the X2 model sitting in the sweet spot between the X1 and the XS. This year, the X2 raises its measured output from 1391 Lumens to 1545. Total weight and run time have stayed the same and the price dropped a bit to $255.

  • Great beam pattern
  • Battery is too heavy to mount on the helmet
  • 1545 measured Lumens on a light this size is incredible
  • Programming requires practice (like the GoPro user interface)
  • Both mounts included and remote switch as well
    • Good packaging and materials
    • Lenses are interchangeable with flood, spot or combination
    • Amazing value and quality for the money
    • Light weight relative to its brightness
    • Great run time and available battery option to optimize for weight
    • Extremely compact packaging means it’s very portable

    Gloworm X2 lens is replaceable with different angle optics.

    Full Review: Gloworm X2

    We rode the X2 on our local trail and love all the details of compactness and versatility. The light system comes in a tiny box that one can just keep in the bike bag all the time. The helmet mount and bar mount are included in the package, and the remote wired switch is just something you don’t see these days. It frees up head unit real estate for critical cooling fins, and it protects the user’s fingers from a potentially hot light head.
