Rated 3/5 based on 258 user votes.

Flashlights are compact and lightweight, making them highly portable. They can easily fit into pockets, backpacks, or glove compartments, allowing you to carry them wherever you go.


Weight842.5 g
Length175 mm
Body diameter55 mm
Head diameter82 mm
Materialaluminium alloy with HAIII hard-anodized finish

This 842.5 g flashlight is quite heavy for a handheld flashlight. The increased weight can provide advantages such as longer runtime, enhanced durability, and the ability to project a brighter and farther-reaching beam. The length of a flashlight can also impact its balance and weight distribution. A well-balanced flashlight, where the weight is evenly distributed, can be more comfortable to hold for longer periods and reduce hand fatigue.

Aluminium body of LR40R V2.0 is known for its durability and strength. It offers excellent resistance to impacts, scratches, and corrosion, making it suitable for rugged outdoor use or in demanding environments. Hard-Anodized Type III (HAIII) is a specific anodizing process that creates a thicker and harder oxide layer compared to regular anodizing. It involves subjecting the aluminum to a higher voltage and a sulfuric acid bath, resulting in a dense and durable coating. The LR40R V2.0 flashlight is available in black.

Luminus has established a positive reputation as a reliable LED manufacturer, and their products are widely used and trusted by lighting professionals and enthusiasts alike. Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. The primary function of the smooth reflector (SMO) is to precisely focus and project the light emitted from the light source into a defined beam pattern. The smooth surface allows for greater reflectivity and light concentration, resulting in a more focused and intense beam with a longer throw distance.

This flashlight has an AR coated lens. This Anti-Reflective coating is a thin optical coating applied to the surface of the lens to minimize reflections and improve light transmission. The LR40R V2.0 has electronic switch. The electronic switches may have a higher likelihood of standby drain compared to mechanical switches since they require a small amount of power for operation.


Flux15000 lm
Intensity202500 cd
Throw900 m
CD/LM factor13.5

The LR40R V2.0 flashlight can produce 15000 lm output. Flashlights with very high lumen outputs demand a substantial amount of power. Ensure you consider the battery capacity, runtime, and rechargeability of the flashlight. The LR40R V2.0 is a 202500 cd flashlight. Flashlights with extremely high luminous intensity often require significant power and generate more heat due to the increased energy output.

The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. The cd/lm factor (candela-to-lumen ratio) provides information about how concentrated or focused the light output of a light source is. A higher cd/lm ratio indicates that the light is more concentrated in a specific direction, while a lower ratio indicates a more diffused or spread-out light output.


Modes4 + 5 modes
Mode memoryyes
Ramping modeno

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The LR40R V2.0 has mode memory. Mode memory means that the flashlight will remember the mode you were using when the light was last turned off, and when you turn it on again. The strobe function on the LR40R V2.0 flashlight is a feature that produces a rapid and repetitive flashing of light. It is designed to create a disorienting or attention-grabbing effect. The LR40R V2.0 has an SOS signal mode. The SOS code consists of three short signals, followed by three long signals, and then three short signals again.

The power source of the LR40R V2.0 flashlight is 3 x integrated 21700 Li-Ion batteries, providing reliable and long-lasting energy for optimal performance. Having a battery indicator on a flashlight is beneficial as it allows users to monitor the battery status and make informed decisions regarding recharging or replacing the battery. It helps prevent unexpected power failures during critical situations and ensures that the flashlight is ready for use when needed.

This flashlight can charge the battery with an integrated charger, and it works with a USB power source. When the LR40R V2.0 flashlight detects that the voltage of the battery has dropped to a certain threshold, it automatically reduces or cuts off the power output to prevent further discharge. This helps to preserve the battery's capacity and prevent it from reaching a critically low voltage level.

The built-in thermal control automatically adjusts brightness output to prevent overheating. The "6" in the IP68 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the LR40R V2.0 flashlight, is fully protected against the entry of dust and other solid objects. The "8" in the IP68 rating indicates the highest level of protection against water ingress.

This flashlight is designed to withstand impacts of up to 1 m without sustaining significant damage, ensuring its durability and reliability even in challenging conditions. The LR40R V2.0 is equipped with USB port that enable you to connect and charge various devices, such as smartphones, tablets, or other USB-powered gadgets.


Package contentsUSB Type-C cable
nylon holster

The package includes a holster to safely store your flashlight. When gripping the flashlight with the lanyard around your wrist, it provides a more secure and stable hold.

The performance of the Fenix LR40R V2.0 flashlight is measured according to the ANSI / NEMA FL1 Standard 30 seconds after switching the light on. The ANSI/NEMA FL1 2009 Standard is a set of flashlight performance guidelines.
