    It's almost too convenient.

    Petzl's innovative Reactik Headlamp automatically adjusts its brightness based off distance in order to provide a longer burn time, visual comfort, and minimal handling. Look from the trail ahead of you down to your skis, or your climbing harness, and you'll instantly notice the headlamp adjusting its brightness from a powerful beam to a close-range light. By adjusting the beam's distance from two-hundred to ninety feet, the Reactik's battery is able to stay bright for nearly half a day, and the battery is USB rechargeable so you don't have to purchase new batteries every time you go ski touring, rock climbing, hiking, or backpacking. To make sure you get the most of the battery, Petzl included a lock function that prevents the headlamp from turning on when it's in your backpack. Petzl also added a partially-padded, adjustable, and washable headband, as if this headlamp weren't already completely convenient enough.

    Just Do It!

    • Familiarity: I've used it once or twice and have initial impressions

    Gets the job done! The wide strap is comfy on the forehead. Super fan of rechargeable batteries. Auto-adjusted brightness is a dream.

    Best Headlamp

      Love this headlamp! I unfortunately lost it and immediately had to buy the same one again! Super bright/lightweight and great for ski tours. The reactive lighting feature works very well and is really convenient - it dims when you're adjusting your gear or looking at others who are close, and then brightens once you're on the move again to see far distances! Highly recommend

      Simple, yet technical

      • Familiarity: I've used it several times

      Most of the time, I pretty much just think a headlamp is a headlamp, is a headlamp. In this case though, you get a bit more. You get a number of beam options (pretty standard), an excellently engineered headband (one of Petzl's strengths in my opinion), and the reactive lighting option. This allows you to use the headlamp in changing light conditions without having to fiddle with the buttons, which is essentially the crux of this product and it works well.

      So disappointed

      • Familiarity: I've used it several times

      I love my Petzl Tikka so much I thought Petzl could do no wrong. However with the reactik they really did do a lot of wrong. The unit is too heavy, noticeably heavier than the Tikka. The on/off button is too small making it impossible to turn on if you’re wearing gloves. The three functions are unintuitive and you have no idea which mode you’re using most of the time. The red light function is difficult to access. The light is bright But the adaptive function is still kind of of clunky. I think Petzl tried to do too much with this light and I miss the simplicity of old.

      Petzl Reactik = best headlamp

        I love the Reactik technology. Batteries seem to last forever because of it. This headlamp is lightweight, feature packed, is super bright(when needed), and has great battery life. I own two of them personally and have given one away as a gift. While the price is a bit higher than other headlamps the convenience and economy that the reactive lighting provides worth it. The reative lighting is also nice for your fellow campers. You get the max brightness you want but the light auto-dims when you turn to a buddy to have a conversation without you doing a thing. The idea of a headlamp is to be hands free. The Reactik allows you to be hands free to a whole new level as you doing have to fiddle with it as conditions change.

        Fantastic Lamp-Durable w/lots of options

        • Familiarity: I've put it through the wringer

        Having had numerous headlamps over the years, this is the one I now go to for an outdoor activity. At first was concerned about taking this on an extended outing, but after lots of use, found it to be incredibly durable, functional and with a long lasting charge.
        Reactive aspect is beneficial for longer battery life and for more comfortable lighting options when close up.

        Love it....

          I had purchased two of these a few years ago for hiking and loved them so much that I decided to order more for hunting and just every day use when in the dark. I now own four of them and I am about to order a couple more. I love that I can use my solar charger when I'm out to charge these up so no batteries are a plus to not have to carry around.

          Great headlamp lost to the wilderness

          • Familiarity: I've used it several times

          I bought this lamp for some military field training. It functioned just as advertised. It was sufficiently bright for any activities I needed to perform in the dark. The red lamp was especially useful for not waking up my fellow trainees at night as we changed watches, and it didn't severely impact your night vision when turned on and off. The waterproof rating of the housing was put to the test when we got caught in a torrential downpour for close to an hour. It worked just fine during and after the storm.

          Unfortunately my lamp was lost in the midst of exchanging equipment at the end of training, but when the time comes to buy a new headlamp I will certainly be reaching for another Petzl model.

          The Reactik is the best!

          • Familiarity: I've put it through the wringer

          I have had the previous version of the Reactik (Tikka R+)for the last few years and I absolutely love it. So when my girlfriend's headlamp took a swim on our last river trip I knew exactly what I should get her. The reactive technology is amazing, it senses how much light is around and dims or brightens your beam accordingly. So if you are next to the campfire it will dim automatically, but when you stumble off into the woods to pee it automatically brightens up. It also has a constant setting for those times when you don't want your headlamp to dim (i.e. when you are riding your bike home from the bar at the end of the night). It also has a red light setting for when you want to preserve your night vision or don't want to wake up your tent-mates. Another feature that I love is the rechargeable lithium ion battery which can be charged via USB, so you can charge it with your computer, a solar panel, or just a USB wall charger.

          Also, I should mention that my headlamp took the same swim as my girlfriend's, and thanks to the IPX-4 waterproofing it still works! This thing kicks serious ass!

          Unanswered Question

          The packaging for the Reactiv states max power is 190 Lumens, but Petzl's website states 220. What is correct?
