Rechargeable Lithium Battery Pack 8.4v 6400 mAh & Pouch Bicycle Bike Cycle LED Light

Product Information

You may prefer a gravel bike light with more power than this if you prefer technical gravel riding and taking your bike down the odd section of singletrack. The cylindric lithium-ion comes in a standard size and therefore cannot be produced in other shapes or sizes. I don't have an hour meter on my flashlights but I've used them 2 winters riding at night and every other non dark ride as a front blinky and countless times as a regular flashlight. To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. If you’re being picky and are worried about the sorts of conditions you’re going to be riding in, pick a light with the highest rating.

The rate of deterioration will be influenced by various factors, including the frequency of charge/discharge cycles, the operating temperature, storage temperature/conditions, etc.Some lights are now also marketed for daytime use, with the appropriate brightness and flash patterns to help keep you seen in bright sunshine and low light.

These cube-shaped Bontrager lights are compact, but the front still puts out 200 lumens and the rear 90 lumens, with both lights offering flashing, constant and constant/flashing modes. A super-bright light that only has enough battery power to put out that headline figure for half an hour isn’t likely to be particularly useful, especially if you’ll need to use the most powerful setting for extended periods. And, just in case the hub dyno fails, you should be carrying some kind of backup for it anyway (Scout motto). Most riders will use a high-powered light on the handlebars for general illumination, alongside a secondary light on their helmet.You can customise the optics of the Gloworm’s three LEDs by replacing the lenses, with spot, honeycomb and wide angle options and there’s a smartphone app, so you can fine-tune the light to match your riding. The addition of a mode or battery indicator would be an area for the brand to explore in a future iteration, otherwise it's top marks.
