Ledlenser ML4 Mini Rechargeable Lantern

The Ledlenser ML4 is an ultra-compact rechargeable lantern weighing just 71g and measuring under 10cm — small enough to clip to a rucksack, hang in a tent or carry in a jacket pocket. Delivering up to 300 lumens of glare-free Micro Prism illumination with IP66 water resistance, a dual power source and six light modes including red light, it is the most portable serious lantern in the Ledlenser range.

Built around a single principle — maximum capability in the smallest possible package — the ML4 is genuinely pocketable yet carries an IP66 water resistance rating and survives a 2-metre drop test. Its dual power source is a standout practical advantage: the ML4 runs on its included rechargeable 14500 lithium-ion battery but also accepts a standard AA alkaline cell when recharging is unavailable — keeping it operational from any outdoor retailer, petrol station or corner shop on extended expeditions far from power.

Ledlenser's Micro Prism Technology across the 9-LED array delivers efficient, even light distribution without the harsh glare of direct LED exposure — available in white (3,700K–4,200K) for bright, neutral task lighting or warm white (2,500K–3,000K) for a softer, more ambient output suited to relaxed evening use.

FAQs about the ML4 Rechargeable Lantern

What is the difference between the ML4 and the ML6?

The ML4 and ML6 are both Ledlenser rechargeable lanterns using Micro Prism Technology, but they serve different needs. The ML4 is the ultra-compact option — 71g, 97mm long, with a carabiner hook for clipping to packs and tents, up to 300 lumens and the significant advantage of AA alkaline battery backup when recharging is unavailable. The ML6 is larger and heavier at 280g and 178mm, but delivers up to 750 lumens, includes a magnetic base for metal surface mounting, a built-in 3,200mAh power bank function for charging other devices and a Bluetooth version with wireless wrist remote. Choose the ML4 for ultralight portability and dual power source flexibility; choose the ML6 for higher output, power bank capability and more mounting options.

Can the ML4 run on a standard AA battery?

Yes. The ML4 accepts a standard AA alkaline battery as an alternative to its included rechargeable 14500 lithium-ion cell — maintaining full functionality without any modification or adapter. This dual power source capability makes the ML4 particularly well suited to remote expeditions and multi-day wild camping where recharging infrastructure is unavailable; AA batteries are available in outdoor retailers, petrol stations and corner shops worldwide, ensuring the ML4 can keep working wherever you are.

How long does the ML4 battery last?

The ML4 offers four runtime options depending on brightness mode: 45 hours at 5 lumens (low power), 8 hours at 50 lumens (mid power), 2.5 hours at 150 lumens (standard) and a short boost burst at 300 lumens maximum. For all-night tent lighting, low-power mode at 5 lumens provides comfortable ambient illumination for nearly two full nights from a single charge. The battery charge indicator and low power warning keep remaining capacity visible at all times.

Is the ML4 waterproof enough for camping in the rain?

Yes. The ML4's IP66 rating confirms protection against powerful water jets from any direction — significantly more robust than a basic splash-resistant rating. For typical UK camping conditions including heavy rain, the IP66 rating provides reliable protection. IP66 does not certify full submersion, so the ML4 should not be dropped into water or used underwater, but for sustained outdoor exposure in all typical British weather conditions it is well protected.

What does red light mode do on the ML4?

Red light mode allows you to illuminate your immediate surroundings — finding kit in your tent, reading a map or moving around a campsite — without disrupting your natural night vision. White light causes the pupils to contract, requiring several minutes of readjustment in darkness; red light avoids this, maintaining your natural low-light vision while still providing practical close-range illumination. It is also less disruptive to other campers nearby, making it the considerate choice on shared campsites after dark.
