While most light manufacturers have worked hard to avoid short circuits by waterproofing their lights, some have gone the extra mile and have been awarded an official IPXX (International Protection) rating. You don't need to use StVZO-approved lights anywhere other than on German roads – however, if you ride solely on the road, investing in a StVZO light could be a good idea. However, although the fade-off is very gradual, there isn’t quite enough spread and power to illuminate the margins of the trail as much as we’d like. In the same way that claimed battery life, weight and a host of other things vary from their real-life measures, the number of lumens a manufacturer claims their light has, compared to how many it actually has, can vary significantly.

This works so well it renders manual modes pointless, so you can have an entirely hands-off experience. hours in its 100-lumen mode, but our tester eked out 10 hours using the mode that alternates between blinking and constant.To use, unscrew the connector on the HL65 Headlight between the switch and battery pack, remove the battery pack from the HL65 (no tools required) and connect the extension cable and battery. The discharge current was set at 2A, which is pretty much the high setting of most Led type lights so this would give a fair time reference of using either battery in your light. Generally speaking, if your light is putting out enough lumens to cast shadows during the day then it’s going to require more power to generate that brightness and last for any significant amount of time.

It’s powerful enough for most black-graded trail centre runs and the beam’s white hue with brown/red highlights illuminates trail surfaces well adding good depth. And, just in case the hub dyno fails, you should be carrying some kind of backup for it anyway (Scout motto). There are a total of eight standard modes, but you can also use Knog's Modemaker app to programme your own settings if you want something specific. New: A brand-new, unused, unopened and undamaged item in original retail packaging (where packaging . They usually use a standard USB cable, although this isn't the case for some lights which have a USB cable with a proprietary connection to the light.

It'll last three hours in high-power mode and all day in lower settings, which are more than adequate after dark.
