Color temperature5500 K
Switchelectronic side

Color temperature is a characteristic of light. It is measured in units called Kelvin (K) and is used to quantify the color appearance of light sources, particularly white light. This TIR lens offers flexibility in achieving various beam patterns, from wide-angle illumination to focused spotlights, depending on the specific design of the lens. The E03R utilizes electronic switch. Electronic switches on flashlights provide a range of advantages and additional features compared to mechanical switches.


Flux260 lm
Intensity430 cd
Throw41 m
CD/LM factor1.65

If you mainly need a flashlight for basic tasks like finding keys, navigating in dimly lit areas, or occasional use around the house, 260 lm can be adequate. 430 cd can provide a reasonable level of luminous intensity for many everyday lighting tasks. The throw distance refers to the maximum distance at which the flashlight can effectively illuminate an object or target. The stated throw distance typically indicates the point at which the brightness falls below a specified threshold, such as 0.25 lux. Flashlights with a higher cd/lm ratio typically excel in long-range throw and focused beam applications, while flashlights with a lower cd/lm ratio may provide a wider and more evenly distributed beam for closer-range illumination or general-purpose use.

The Fenix E03R flashlight is powered by integrated Li-Ion battery. The battery indicator lets you know when the battery is low, charging, or fully charged. USB rechargeable flashlights have become increasingly popular in recent years due to their convenience and sustainability. This flashlight has a built-in low voltage protection (LVP) to prevent damage to the cell from over-discharge, so protected cells are not necessary.

The E03R has thermal protection feature. The thermal protection mechanisms are designed to monitor and regulate the temperature of the flashlight during operation. This feature helps prevent overheating, which can be detrimental to the flashlight's performance, battery, and overall safety. The "6" in the IP66 rating represents the level of protection against solid objects, specifically dust and foreign particles. It indicates that the E03R flashlight, is fully protected against the entry of dust and other solid objects. The IP66 rating indicates that the E03R flashlight has a protection against water jets.


Package contentsUSB Type-C OTG cable
