Biolite energy

Invest in for both the outdoor and emerging markets.The CommunityAnytime we tell someone that the smoke from indoor cooking fires kills four million people annually, we’re almost always met with a gasp followed by “I had NO idea.”That’s where this community comes in – getting the word out. But we’re not going to do it through doom and gloom; we’re doing it with real solutions and some serious perseverance. And that takes all of us. Your support is a signal to the broader world that this is something worth caring about and that you believe we all have the potential to unlock a world of better energy. And your actual use of our products is instant proof to new BioLiters that we’re creating solutions that really work.Each time you tell a neighboring camper about BioLite, email a friend about our Kickstarter campaign, or share how you’re bringing #energyeverywhere on Instagram, you’re helping grow the BioLite community. That, in turn, grows awareness about our mission and helps us gain momentum to grow and reach even more households living in energy poverty. This public display of support not only inspires our team to keep going (we love your emails!), it helps build confidence with our HomeStove customers. They take pride in the fact that the technology inside their HomeStove is the same inside the award-winning products that you purchase right here at the BioLite Shop.The ImpactThis global community has made some amazing things happen.Together we’ve enabled 1,400,941 people to bring clean, reliable cooking and energy into their lives. 1,499,535,545 watt-hours of electricity have been generated in off grid households and 403,427 tonnes of CO2e have been offset. And we’re just getting started.We said it in the video above, but we’ll say it again: Thank You.Thank you for helping us grow, staying engaged, and showing the world, one campsite at a time, that good energy is all around us.Editor's note: This article was originally published in 2016 as a part of our Business of Impact Series.

That's incredibly lightweight. The rear red beam is an unusual feature, handy for group situations.This headlamp is useful across a variety of situations, including for astronomers and astrophotographers, although it was initially designed for people who like to run in the evenings. As we discussed in our BioLite HeadLamp 425 review, one of our favorite things is how comfortable the headlamp is. Its battery is also placed at the back of the band, which means much better weight distribution and it doesn't feel too cumbersome to wear on the forehead. The power button also sticks out enough so it's easy to locate, even if you've got your running gloves on.That said, some might find having a battery pack on the back of your head isn't all that practical. If you're going to be laid down — whether that's reading in bed or working under your car late at night — it's going to be uncomfortable to lie on. If those are primary uses for you, you might want to choose something else rather than a BioLite headlamp, which all mostly share this design choice. But for most other uses where you're upright and moving around, having less weight at the front of your head is a major plus.Furthermore, USB-C charging is a great bonus—no need to dig out batteries or find older cables! It charges quickly too: the BioLite can go from empty to full in just about two hours. And when it's in use, we've thoroughly enjoyed its four tilt positions, which make it very versatile and allow you to see both distant and close objects.One last plus: by buying it you're even supporting BioLite's mission to reduce CO2 emissions and increase access to clean energy.Read our full BioLite HeadLamp 425 reviewSwipe to scroll horizontallyTest ResultsAttributesNotesDesignThe lamp sits flat to your forehead, the battery sits at the back of your head so it's pretty comfortable, its available in three colors FunctionalityUSB-C charging with a 'reserve mode' that provides an hour of backup lightPerformanceThe battery lasts a long time and it's very comfortable to wear, the red rear flood is novel tooBack to the top ⤴Best general purpose headlampThe only thing that would improve this headlamp is USB-C charging instead of micro USB.(Image credit: Tantse Walter)Best general purpose: We love this reliable headlamp and its hybrid batterySpecificationsLED Color: White and redBrigntness (Lumens): 450Runtime: 2 hrs (highest setting), 130 hrs (lowest
