Mimicking natural light and incorporating additional settings and brightness levels, the BioLite AlpenGlow Lantern 250 ups the ambience for your next outdoor adventure. In addition to cranking out up to 250 lumens of bright illumination, the innovative rechargeable light also doubles as a charger for small electronics. A unique shape and design allows light to emanate from almost every inch of the 3.7' x 3' lantern. A simple easy-to-use button lets you choose from cool, warm, and color modes and full or half settings. The integrated 3,200 mAh battery provides 4.5 hours of burn time on high. The battery is recharged via a micro USB input and a USB A output enables you to power up your phone, a headlamp, or other small devices.
