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. While the interface between light and mount is good, the plastic clamp is hard to tighten, although its narrow width does leave space on the bar. The X-Power 1800’s CNC-machined, black-anodised and polished head unit houses four LEDs that look like they put out more light than Moon’s quoted 1,800 lumens. 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.

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.Battery and LED tech is improving all the time, and although lights with dedicated, separate battery packs will last longer than combined all-in-one units, the gap between the two is narrowing. It’s also important to check out what extras are included with the light such as remotes, extra-long cables to connect battery and head unit, multiple mounting brackets, and whether they’ve got a certified waterproof rating, are shock-resistant and have battery or mode indicators. 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.

With six XPL2 LEDs and 24 modes in total, the Exposure Six Pack is an impressive beast, reflected in its 406g weight.

The light beam has a central focus, illuminating roads well, and the peripheral illumination helps you see what’s at the edge of your vision.

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. High and low beams have different patterns, with the high beam focusing light in the distance and the low beam flooding the closer area. Some of the sets in this list are no longer available, but we have listed the lights individually as we still think they would make good combinations.In an ideal world, you would be able to have a mounting system that is perfectly simple, lightning-quick to install and remove, totally secure and infinitely durable… But in reality, there’s usually a bit of a compromise between those various characteristics. You’ll only get around 80 minutes at this power, but dropping it down to the second highest output (which sits at 500 lumens) provides just under three hours of run time, which ought to be enough for even the longest of commutes. This compatible replacement battery pack from the brand vhbw is suitable for use in your bicycle light or bicycle lamp. Are you looking to mount a light on multiple bikes It's worth paying attention to the extras that come with a light to make sure it is suitable for your specific needs. With the optics swapped out, there was a good spread of light to help pick out turns and a good throw of light down the trail with plenty of illumination, so you shouldn’t need a second light source.

The tough, rubber-band style mounting system makes adding/removing the lights a cinch, though they’re arguably a little less secure than ratcheted or bolt-mounted options.s predecessor, the MagicShine Monteer 8000S Galaxy, also scored a full five stars last year and is worth consideration. Of course, Night Rider will actually test your light if it goes back to them, so weigh your abilities to diagnose other issues that may be battery related vs. On paper, Topeak’s Redlite Aero 1W is nothing remarkable, but it’s always the one that’s ready to go and has never failed us out on a ride. The intermediate settings are well thought-out and, although we’d prefer a slightly smoother transition between these, it is possible to programme the light to suit your needs.
