Headband flashlight Petzl E104BA00 LED 500 lm USB rechargeable

The Petzl E104BA00 headband flashlight delivers up to 500 lumens in a compact, lightweight design weighing approximately 79 g. Its hybrid concept accepts the included CORE rechargeable battery (USB rechargeable) or three AAA/LR03 batteries, allowing flexibility for extended outings. The ultra-thin lamp body and AIRFIT semi-rigid headband place the energy source at the rear for balanced wearing comfort and reduced bulk. Multiple LEDs provide even light distribution with selectable beam types and brightness levels for close-range tasks and movement at distance. The unit is water-resistant to IPX4 and can be converted into a lantern using the storage pouch.

Advantages

The lamp combines high light output and low weight for reduced fatigue during prolonged use. The AIRFIT headband and rear-mounted battery pack distribute weight evenly, improving comfort and stability in dynamic activities. Multiple LEDs and two beam shapes ensure homogeneous lighting and adaptable illumination for various tasks. The HYBRID CONCEPT lets you use the CORE rechargeable battery or standard AAA cells, and the micro-USB charging port simplifies recharging. Additional features such as a battery charge indicator, lock functions to prevent accidental activation and reflective elements on the rear increase practicality and safety.

Usage recommendations

For longest runtime, use the included CORE rechargeable battery and lower brightness levels; keep the headband dry and rinse off dirt after contact with heavy sweat or mud. Use the lock function when storing the lamp to avoid accidental discharge, and periodically check the battery charge indicator before long trips.
