The Gloworm Alpha bike light was clearly designed by folks who spend a lot of time riding their mountain bikes in the dark. This new, 69g light (lamp only) is the lightest and most compact in the Gloworm line, yet it still offers almost all of the bells and whistles the brand is known for.
Gloworm Alpha specs
- 1200Lm max brightness
- Weight: 69g (Light only) = 17.39Lm per gram
- Runtime: 2hrs at max
- Mounts: Handlebar and helmet included
- Price: $139 MSRP
- Available from Gloworm or compare prices
The Gloworm Alpha includes swappable optics so buyers can create either a tight or wide beam pattern, depending on local conditions and riding style. Not only that, light modes can be customized beyond the stock super dim, low, medium, and high modes.
Because the Alpha lamp and battery are so lightweight, mounting the entire system to a helmet is comfortable enough that there’s no need to carry the battery in a pack or jersey pocket separately. At the maximum, 1200Lm setting, the Gloworm Alpha light promises about two hours of battery life; for an extra $40, the Alpha Plus doubles that to four hours.
A remote control is available for purchase separately, and can be used to operate the Alpha alone, or in tandem with another Gloworm light. Gloworm lights utilize a GoPro-compatible mounting system, and everything needed to mount the light and battery to a handlebar or helmet is included in the box. Note that the included handlebar mount fits 31.8mm diameter bars so if you’re running 35s, you’ll need to purchase a larger mount.
