Now featuring a 250-lumen beam and a lighter, smaller, tighter waterproof body with an updated user interface, the Cosmo 250 can handle everything from your evening bike commute to that weekend backpacking trip.
Black Diamond says:
With 250 lumens of power housed in a super compact, waterproof body, the Cosmos 250 is perfect for urban adventures and overnighters in the woods. The Cosmo’s new, compact body, is more ergonomic with a lower profile for improved balance, and the updated user interface includes a second switch for easy lens selection. In addition, the updated optical efficiency not only provides brighter light, but also saves battery life. And thanks to its fully waterproof construction, the Cosmo keeps lighting the way through full-on storms, whether you’re forced to bike home in the rain, or you’re hiking back to camp in an unexpected downpour.
Black Diamond's Cosmo 250 Lumens Headlamp is great piece of kit. A simple, effective, and very bright head torch that is designed for a range of activities. The Cosmo uses 3 AAA batteries to provide up to 250 lumens of light. With modes for red light and strobe flashing it is much easier to use and cycle through than many other models. The waterproof rating is pretty impressive more most people's use and the additional features like the lockout mode are a nice touch for a headtorch at this price.
Some people prefer the battery option to the rechargeable cells so that you can replace them on extended trips or overnight outings where the light from the headlamp is critical. For multiple-night trips I much prefer this option and the Cosmo provides all the light needed for the campsite through to night navigation needs - with the added bonus of being able to take spare batteries that are quickly and easily changed.
