The BioLite 200 headlamp has a lot going for it. One, it’s super-lightweight and low-profile, so it won’t bounce. Great for runners. Two, it’s rechargeable, delivering its ample 200-lumens of LED for up to 3 hours on high & up to 30 hours on low, with no alkaline batteries for the landfill. The light also tilts for hands-free utility & it switches modes between, high, low, strobe, & red.
