Despite its price, this three AAA battery powered light is a genuine Petzl product, meaning excellent reliability. If the lamp finds more use than originally expected, you can upgrade it later with the Petzl Core battery, thus converting it into a rechargeable light. In addition it can be used with separately available AAA size NiMH batteries. Battery life chart as extra image: the upper part refers to use with AAA cells, the lower part with the separately available [Core battery](/core-2). Use the separately available [Bike Plate 2 adapter](/bike-adapt-palte-2) and [Adapter Kit](/adapter-kit-tikka-zipka) to mount this helmet on your bicycle's handlebar or bicycle helmet. Climbing helmets, work safety helmets and skate style bicycle helmets have their [own adapter plate](/mountplate-helmet-adapter/). Updated model: the battery run time is now 30 minutes longer and the lamp contains a lot of recycled materials. - Wide, comfortable headband - Three power settings, maximum running tim
