4000LM LED Flashlight with Adjustable Zoom and Five Modes, Aluminium Alloy Build

This high-output LED flashlight delivers up to 4000 lumens with an irradiation range of 200 to 500 metres, suited to outdoor pursuits such as mountain climbing, camping, hiking, and forest exploration. Its telescoping head allows you to switch between a focused spot beam and a wide flood beam depending on your task. The aluminium alloy casing provides a robust, skid-proof grip, while the IPX5 water-resistance rating and 1.5-metre shock resistance add reliability in unpredictable conditions. Weighing only 87g and measuring 12.9cm in length, this torch is portable enough for a jacket pocket or a backpack side pocket.

Features and Construction

The flashlight is built around a bright XM-L T6 LED array and a constant-current driver that makes full use of the battery charge. The body is machined from aluminium alloy with a textured, skid-proof surface for a secure hold even with wet or gloved hands.

Brightness and Beam Control

With a maximum output of 4000 lumens, the flashlight can illuminate objects at distances between 200 and 500 metres. The telescoping head mechanism lets you narrow the beam to a concentrated spot or widen it to cover a broader area, giving you flexibility in tight spaces or open terrain.

Lighting Modes

Five modes are selectable with a single button: high, middle, low, strobe, and SOS. This allows you to conserve battery in low-light situations, signal for help, or disorient in emergency scenarios.

Water and Shock Resistance

The flashlight is rated IPX5 for water resistance, meaning it can withstand low-pressure water jets and rain. It is also shock-proof to approximately 1.5 metres, reducing the risk of damage from accidental drops.

Power and Battery Options

The flashlight accepts either one 18650 Li-ion battery or three AAA batteries (both sold separately). The 18650 battery recommended is a 3.7V 4200mAh protected Li-ion cell with over-temperature, over-current, and short-circuit protection.

Battery Compatibility

Using the 18650 format provides a longer run time and higher current delivery. The internal constant-current driver works across a wide voltage range, extracting maximum energy from the cell before the light dims.

Charging the Battery

If you choose the rechargeable 18650 option, the required charger accepts AC input 110-220V at 47-63Hz and outputs 3.7V at 450mAh. No battery or charger is supplied with the flashlight.

Uses and Placement

This flashlight is designed for outdoor activities where reliable, adjustable lighting is important. Its compact dimensions (12.9cm long, 32mm head, 25mm base) and 87g weight make it easy to carry on long walks, climbs, or camps.

Outdoor Adventures

Ideal for cavers, forest explorers, hunters, and fishers who need a strong beam that can cover both short-range close work and longer-distance scanning. The zoom feature is particularly useful for spotting wildlife or navigating uneven ground.

Home and Workshop Use

Around the house, the flashlight helps with repairs, finding small objects in dark corners, or providing emergency light during a power cut. The strobe mode can also be used as a safety signal.

Benefits and Buying Value

The combination of a high lumen output, adjustable beam, multiple modes, and a durable aluminium body makes this a versatile lighting tool. Its lightweight design means it adds negligible weight to your pack or pocket.

Reuse and Low Maintenance

With the rechargeable 18650 battery option, you can reuse the cell hundreds of times. The constant-current circuit prolongs battery life by drawing power evenly until the charge is depleted.

Why Choose This Product

This flashlight offers up to 4000 lumens in a compact, shock-resistant, and water-resistant form. The built-in zoom and five lighting modes provide flexibility that a fixed-beam torch cannot match, all without relying on batteries that are supplied, so you can choose your preferred power source.
