If it is and the lamp still doesn’t work, check for any visible signs of damage to either the lamp unit or battery pack which may have caused the problem. Run time at full power was bang on the 1 hour 30 minutes claimed by Moon too, which is very good considering the amount of power on tap. Each has an ambient light sensor to adjust brightness and you can hook them up via ANT with a Garmin cycle computer for auto on when you start to ride and to swap between modes.

It lives up to Magicshine’s claims, pumping out an incredible amount of well-distributed light for brilliant trail context that boosts rider confidence sky-high. We were impressed with the run time, although switching between modes was a bit tricky, as the top button isn’t illuminated. Beam pattern refers to how the lights disperse light across the trail, and it can be just as important as lumens when it comes to how well you can see.If the LED on the charger remains green, it could mean that the battery protection circuit has been activated. The light will run for three hours, 30 minutes on full-whack and its switch indicates the charge level.

The narrow beam might not suit mountain bikers or bikepackers cycling at night, but there are more StVZO light options becoming available that let you change between high and low beams to get around this issue.This instructable will show how to convert (AA or AAA powered) bicycle lights to use a USB rechargeable lithium battery pack. The other option is to get a light that runs off of common, easily replaceable cells like 14500 or 18650 lithium or standard AA size NiMH. Its maximum 7,200-lumen output is as powerful as it sounds, and it has a super-focused centralised spot, meaning no obstacle goes unseen. The spot is fairly focused on the front of the bike, but its good power output means beam spread is okay (though not amazing) with the standard lenses installed.

Alex is also a dedicated eMTB rider, and still dabbles in racing of a sort, doing his best to top the Strava leaderboard on the steepest, gnarliest and twistiest trails the Tweed Valley has to offer – just for fun, of course.

It even has a USB port to allow you to use it as a battery pack to charge other gadgets (such as your phone, for example). The Lezyne Hecto Drive XL's 500 lumens is enough for a decent pace on unlit bike paths, though with only one hour of run time at maximum output, the Hecto is best for use as an urban light. Ideally, the temperature should be lower than 20C – the cooler, the better - so a cupboard in a garage is ideal, but only if it is dry.A gravel bike light should be more powerful than a road bike light to illuminate unlit trails and gravel paths.
