Moon - Cerberus Rechargeable Seatpost Mounted Rear Bike Light 150 Max Lumens, Daytime Mode, USB Type C, 140 Hours Max Runtime

Product Information

If you're returning to cycling after a very long hiatus, you'll be pleased to know that bike lights have come a long way this century! The rechargeable, LED light is now king, and unlike the notorious Ever Ready lights that were popular in the '70s and '80s, you don't need to spend a fortune on batteries to get your feeble beam to work for a couple of hours. With the VLS feature, each mode can also be adjusted between the minimum and maximum settings pertaining to the mode. Constant modes are limited to 5-50 lumen while flash and steady flash are limited to 10-100 lumen. Daytime flash can be adjusted to the full range of 10-150 lumen which can push the runtime all the way to 140 hours in the lowest 10 lumen setting. Although the three COB LED design of the Cerberus improves side visibility, due to the narrow profile of the taillight side visibility is limited to around 270°. If you’re looking for better side visibility, larger lights like the NiteRider Bullet 200 should be considered. Also while the COB LED design looks more visually attractive and is visible during daytime, the beam is less focused than lights like the Bontrager Ion RT or Light and Motion Vya Switch which means the Cerberus isn’t as visible from longer distances. THE VERDICT The constant modes are a claimed 3:30 and 1:45 but these can be stretched to 18 hours using the VLS button (variable lumen system), which is basically a dimmer switch to preserve battery life or spare your riding mates' eyes. VLS can also be applied to the flashing modes. VARIABLE LUMEN SYSTEM: This is a feature Moon Sport has incorporated into most of their lights and allows you to adjust the output of each mode independently. Once activated, the light ramps up from minimum to maximum power for that mode (note it flashes at each extreme to indicate a max/min has been reached) slowly until you select the desired level. The chosen output value overrides the factory defaults allowing for full customization. Although it’s a cool feature to see, we imagine most users won’t utilize it as the factory defaults are more than sufficient. And unlike most lights, the Cerberus is not just designed for a round-profile seatpost. The clamp has a clever system whereby two hinged wings and a flexible rubber pad make it fit both round-section and the sharpest bladed seatposts. You choose from three supplied rubber bands in the box to get the right fit, but any rubber band will do, such as the ones that come with Garmin stem mounts.

Do you need to abide by these rules? If you live in Germany then yes, of course! For the rest of us, we can use our own judgement to decide which beam shape and style is best for us. It is perhaps polite and common sense to use front and rear lights that don't dazzle other cyclists, motorists and pedestrians, and if you want to make sure of this then you can look for beams that are StVZO-compliant. The problem is that not many manufacturers outside of Germany make them, with Lezyne and Cateye being two rare examples of brands that sell StVZO-compliant lights in the UK. Some brands such as Ravemen and Moon use refractive lenses to shape the beam so less of it's going into the sky, and we've found Ravemen's version with refractive elements to spread and lower the beam to be especially effective.

This light comes with 3 multi-directional COB LEDs which provides a large, wide beam that produces 270-degrees of visibility - ideal for commuters aiming to stay seen amongst multiple lanes of traffic. Light Modes The USB-C has reliably charged inside 2 hours. There's a tiny LEDon the side of the light that will glow a steady purple when the battery level is low.

Klarna.com/uk/terms-and-conditions The Cerberus light does the business at the far end of the bike with one rear LED and two side COB LED strips powered by a rechargeable 500mAh Li-Po battery. Again the flush side button is awkward to find in gloves, but it toggles through two solid and three flashing modes with a “press until you’re happy with the brightness”‘Variable Lumen System’ setting too. With the 50Lm max in the solid modes, 100Lm in the standard flash modes and a brutally bright 150Lm max in the Daylight Flash mode, no one has an excuse for not seeing you.

In terms of visibility,the Cerberusis great. Road users to yourrear, left and right get a decent blast of light in all modes. From a great distance it's not as visible as some others, but it casts its beam far enough for you to feel safe.Lights for riding off-road at night need to be much brighter, and thanks to modern technology you can get front lights that will illuminate a trail almost like it's daytime. Trail lights will often have beams advertised at well over 1,000 lumens, sometimes as high as 5,000. The Cerberus has a two button interface with both buttons on the top left side of the taillight. The power button is on the top while the one below it is primarily used for the VLS feature. Aside from debossed icons on the buttons, there isn’t any tactile or material difference to them. Because of this, we found the buttons difficult to use with gloves as they are hard to differentiate from the taillight housing. Between the buttons is also an indicator LED that is used to show when charging is active as well as indicate low battery. As with other rechargeable taillights, the battery indicator is subtle and easy to overlook. There is an “auto safe” mode that extends the runtime when the battery is low, but you’ll still need to remember to charge the light regularly to avoid running out of battery while riding.

Also included is the VLS system which allows you to set any lumen you want – simply press and hold the VLS button. When your bike arrives final assembly will be required. Don’t worry we’ve got you covered. Our step by step instructional video can be found here as well as our easy to follow instructions. Emma’s first encounters with a bike were in between swimming and running. Soon after competing for GB in the World Age Group Triathlon Championships in Edmonton in 2001 she saw the light and decided to focus on cycling. A short press switches on the light and you can access 5 different modes, all of which are customisable thanks to the Variable Lumen System. Like so many lights, getting used to how the Cerberus works is paramount to getting the best out of it. Once you’ve got to grips with it, it can genuinely cater for any kind of riding.Das Licht an sicht ist sehr wertig aufgebaut, hat nen abgedichteten USB-C Anschluss, die Halterung des Lampenkörpers selbst ist hervorragend flexibel durch die kleinen in Scharnieren gelagerten "Ohren" und die Leuchtleistung sowie die Möglichkeit, Blinken einzustellen ist ganz wunderbar. Moon’s Cerberus, rear light, comes with 3 multi-directional COB LEDs which provides a large, wide beam that produces 270-degrees of visibility. This is ideal for commuters aiming to stay seen amongst multiple lanes of traffic. Es liegen mehrere O-Ringe dabei, mit denen man das Licht am Rahmen befestigen kann. Ich habe sie gegen ein Gummi ausgetauscht, dass sich für mich etwas passender anfühlte, aber sicher taugen die beigelegten Gummis ebenfalls. The light comes with rugged construction with an IPX7 water and dust resistant certification. In the Box Long Hold: activates the VLS mode and ramps the output from min to max mode slowly, release the button at the desired output
