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

Flux360 lm
Intensity7000 cd
Throw167 m
CD/LM factor19.44

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.

The Nitecore EA21 flashlight is powered by 2 x AA batteries. The EA21 cannot charge batteries. You may need an external charger to keep your battery going. Use a protected battery. 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.
