The 151 g flashlight is generally comfortable to hold for extended periods and easy to carry in pockets or bags. They are suitable for various applications such as camping, hiking, or emergency situations. A 120-gram flashlight strikes a good balance between functionality, convenience, and weight. The length of the EA41 flashlight can affect its portability. A shorter flashlight is generally easier to carry in a pocket, bag, or pouch, making it more convenient for everyday use or when you're on the go.

The aluminium body of EA41 has excellent thermal conductivity, meaning it can effectively dissipate heat generated by the flashlight's components, such as the LED or battery. The HAIII coating provides excellent corrosion resistance, protecting the underlying aluminum from exposure to moisture, humidity, and other corrosive elements. It helps maintain the appearance and functionality of the flashlight, even in harsh environments. The EA41 flashlight is offered in a stylish black color.

System

Emitter	Cree XM-L2 U2 LED
Color temperature	6500 K
Reflector	SMO
Lens	toughtened AR coated glass
Switch	dual electronic side

Cree LEDs are commonly used in a wide range of lighting applications. Their products are trusted by lighting professionals and have gained a strong reputation for quality and performance. The choice of color temperature depends on the specific lighting application and personal preferences. With the smooth reflector of the EA41, the beam tends to have a well-defined hotspot at the center, which provides a concentrated beam of light for long-range applications.

The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. This can increase the overall brightness and efficiency of the EA41 flashlight. The EA41 has electronic switch. Some flashlights with electronic switches have programmable features that allow users to customize the behavior of the flashlight. This may include setting specific modes, configuring brightness levels, or enabling unique functions according to individual preferences.

Performance

Flux	1020 lm
Intensity	28276 cd
Throw	336 m
CD/LM factor	27.72

With 1020 lm, the EA41 flashlight will offer a brighter and more powerful beam of light. This higher output can be advantageous in various situations where you require enhanced visibility or need to illuminate larger areas. The EA41 flashlight with 28276 cd has an extended throw distance, allowing you to illuminate objects or areas at greater distances. This can be advantageous for outdoor activities, search and rescue operations, or scenarios where long-range visibility is required.

The throw is the calculated distance in meters at which the flashlight produces a light intensity of 0.25 lux. Candela per lumen (cd/lm) is a measure of a flashlight's beam intensity relative to its total luminous flux or output. It quantifies the concentration of light emitted by the flashlight in relation to the total amount of light produced.

Software

Modes	5 modes
Mode memory	yes
Ramping mode	no
Strobe	yes
SOS/Beacon	yes

Modes on a flashlight refer to different output settings or levels of brightness that can be selected to suit different needs and preferences. The EA41 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. Strobe mode on EA41 flashlight produces a rapid, repeated flashing of light. It can be used for signaling purposes, self-defense, or attracting attention in emergency situations. SOS mode of the EA41 produces a specific sequence of long and short flashes to signal distress or emergency situations. It is commonly used in outdoor adventures or survival scenarios.

Features

Battery	4 x AA batteries
Battery indicator	yes
Charger port	no
LVP	no
Thermal regulation	no
Protection	IPx8
AUX LEDs	no
Magnetic	no

The EA41 flashlight utilizes 4 x AA batteries as its power source. The EA41 has a battery indicator. A battery indicator is a feature that provides information about the remaining power level of the flashlight's battery. It helps users monitor the battery status and estimate how much runtime they have left before the battery needs to be recharged or replaced. The EA41 cannot charge batteries directly. You may need an external charger to keep your battery going.

A protected battery is recommended as the light itself does not have low voltage protection (LVP). This flashlight doesn't have built-in temperature control. Flashlights without thermal protection may rely on other design elements for heat dissipation, such as heat sinks, fins, or body materials with good thermal conductivity. The "8" in the IPx8 rating indicates the highest level of protection against water ingress.

Accessories

Package contents	lanyard nylon holster spare o-ring

The holster provides a reliable and convenient way to keep your flashlight securely protected when not in use. The lanyard prevents accidental loss of the flashlight. Instead of searching for compatible O-rings or waiting for replacements to arrive, having spare O-rings readily available allows for convenient and immediate repairs or replacements.

The performance of the Nitecore EA41 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.
