Headlamp 800 from BioLite is a light headlamp with a slim design for hiking. A normal headlamp usually adjusts the light as the battery decreases, but with the Constant Mode mode, the lamp maintains the selected brightness until the battery runs out or until you choose to change it yourself. If you need a longer battery life, you can easily connect the headlamp to a power bank (not included) and use the lamp's Pass-Thru+ function to charge the lamp while you use it.\n\nThe rear light with red light in flood or strobe/flashing mode provides increased visibility in the dark.Battery: 3000 mAh Li-ion with Micro-USB chargingBrightness: Low 5 lm / Medium 250 lm / High 500 lm / Burst 800 lmBattery time: 150 h / 4 h / 2 h / 30 secondsLight modesWhite light: spotlight, spotlight + flood, flood, strobe/flashing, 30 second burstRed light: flood, rear flood, rear strobe/flashing BioLite Headlamp 800 Grey/Black | Buy BioLite Headlamp 800 Grey/Black here | Outnorth
