Nitecore EA21 specifications

Flashlights are unlike ambient or overhead lights. They let you aim the light where you need it.

Body, materials, weight, colors

The EA21 is small, compact, and designed for ultra-portability. The length of a flashlight can affect how it feels in your hand and how you can grip and maneuver it. The aluminium body of the EA21 has excellent thermal conductivity. This means it can effectively dissipate heat generated by the flashlight's components. The body of EA21 flashlight treated with a Type III hard-anodized, anti-abrasive finish. The EA21 flashlight comes in a stylish black color.

System, LED, lens, reflector

Cree is a US-based LED manufacturer. It is well-regarded for its high-quality products and innovation in lighting. Color temperature is a characteristic of light. It is used to quantify the color appearance of light sources. The EA21 has a smooth reflector. The right reflector focuses light well. It gives you a better hotspot, and it throws better. The AR coating reduces the loss of light due to reflections, allowing more light to pass through the lens. The flashlight has electronic switches. They have many benefits and extra features compared to mechanical switches.

Performance, flux, intensity, throw

360 lm can provide a decent amount of brightness and be suitable for many everyday tasks. The EA21 flashlight has 7000 cd. It provides a much brighter and more intense beam. The throw is the distance in meters at which the flashlight produces a light intensity of 0.25 lux. The cd/lm factor is the candela-to-lumen ratio. It shows how concentrated a light source's output is.

Software, user interface, modes

A flashlight's modes are different output settings or brightness levels. They can be chosen to meet different needs and preferences. The flashlight has mode memory. It remembers the mode you were using when the light was last turned off. It stays in that mode when you turn it on again. You can use Strobe for signaling purposes. It can also be used for self-defense or to attract attention in emergency situations. The EA21's SOS mode produces a specific sequence of long and short flashes. It signals distress or emergency.

This flashlight lacks low voltage protection (LVP). Flashlights without thermal protection may rely on other design elements to dissipate heat. These elements include heat sinks, fins, or body materials with good thermal conductivity. The "8" in the IPx8 rating means the highest level of protection. It is against water ingress.
