Materialaluminium alloy with HAIII hard-anodized finish

This 30 g flashlight would generally be considered lightweight and easy to handle for most people. 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 E03R 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.

The HAIII process produces a hard and wear-resistant surface on the aluminum, making it more resistant to scratches, abrasions, and impacts. This improves the overall durability of the flashlight body. The E03R V2.0 flashlight is available in gray.


Emitter1 x unspecified White LED, 1 x unspecified Red LED
Color temperature5500 K
Switchelectronic side

Warm white light is generally considered more comfortable and less harsh on the eyes compared to cool white light. A TIR lens works on the principle of total internal reflection. The TIR lens collimates the LED light into efficient, well-controlled light beams that maximize the usable lumens in the target area. The E03R 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.


Flux500 lm
Intensity2082 cd
Throw91 m
CD/LM factor4.16

500 lm can provide a decent amount of brightness and be suitable for many everyday tasks, it may not be sufficient for certain scenarios or individuals with specific requirements. With 2082 cd, the E03R V2.0 flashlight provides a noticeably brighter and more intense beam of light. It can illuminate objects or areas with greater clarity and visibility, even at longer distances. 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.

This flashlight can charge the battery with an integrated charger, and it works with a USB power source. When the E03R 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 IP66 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the E03R V2.0 flashlight, is fully protected against the entry of dust and other solid objects. The IP66 rating indicates that the E03R V2.0 flashlight has a protection against water jets. The impact resistance of a flashlight can vary depending on its design, construction, and intended use.


Package contentsUSB Type-C cable

The performance of the Fenix E03R 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.
