LEDLENSER MH4, 750 mAh, 400 lm, Headlamp

The LEDLENSER MH4 Rechargeable Headlamp is a compact LED light designed for hiking, camping, and hands-free work in low-light environments. It produces up to 400 lumens and throws a focused beam up to 180 metres, allowing clear visibility over long distances. The runtime extends to 35 hours on the lowest output setting, making it suitable for extended overnight trips. A manual focus system lets the user switch between broad-area illumination and a concentrated spotlight.

Weighing 94 grams, the headlamp uses an ABS plastic housing that withstands drops from up to 2 metres. An adjustable headband and a pivoting lamp head direct the beam where needed without shifting the entire unit. Power comes from an included 750 mAh 14500 lithium-ion battery that recharges via a magnetic USB cable in 2.5 hours; a standard AA battery can also be used as a backup. The light features three modes, including a red night-vision setting to preserve dark adaptation. An IP54 rating protects the internal components against dust and water splashes.

• Detachable strap enables the light to be used as a handheld device
• Battery-level indicator provides real-time status of remaining power
• Operating temperature range from −20 to 40 °C supports varied climates
• Controls via buttons and a rotary dial allow adjustments while wearing
• Minimum beam distance of 40 metres provides closer proximity visibility
• Lowest output setting produces 20 lumens for up-close tasks
