The Ledlenser ML4 Warm Light Lantern is a compact rechargeable mini lantern designed for camping, backpacking, travel and everyday ambient lighting, providing a soft, comfortable glow in a lightweight and portable design
Built for outdoor adventures and relaxed evenings, the Ledlenser ML4 Warm Light combines efficient illumination, versatile power options and practical mounting features in an ultra-compact package. Its warm white light creates a comfortable atmosphere in tents, campsites and living spaces while reducing glare for more pleasant use in low-light conditions.
Featuring Micro Prism Technology, the ML4 Warm Light delivers efficient, even and glare-free illumination with excellent light distribution. The warm white LED produces a natural 2500–3000 K colour temperature with CRI 80 for comfortable, eye-friendly lighting, while the additional red light mode helps preserve night vision during camping, navigation and other nighttime activities.
The lantern offers flexible power options with Dual Power Technology, allowing it to run on the included rechargeable 14500 Li-ion battery or standard AA alkaline and NiMH batteries when charging is unavailable. The convenient Magnetic Charge System enables easy USB charging, while integrated battery and charge indicators help monitor remaining power.
Designed for easy use outdoors, the ML4 Warm Light features an integrated carabiner clip for hanging from tents, backpacks, branches or gear. Glow-in-the-dark elements make the lantern easy to locate at night, while Smart Light Technology provides multiple lighting modes controlled through a simple front switch.
Despite its compact size, the Ledlenser ML4 Warm Light delivers up to 300 lumens in Boost mode and offers up to 40 hours of runtime on Low Power. With IP66 dust and water resistance and 2-metre drop protection, it is built to handle outdoor conditions while remaining lightweight and easy to carry.
