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 MT21A 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.
Mechanical switches are usually robust. They resist wear and tear and work in many environments. The rear switch is at the end of the MT21A flashlight. It helps you hold it securely.

260 lm can provide a decent amount of brightness and be suitable for many everyday tasks. The MT21A flashlight has 10000 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
Modes | 4 modes |
---|---|
Mode memory | no |
Ramping mode | no |
Strobe | yes |
SOS/Beacon | yes |
A flashlight's modes are different output settings or brightness levels. They can be chosen to meet different needs and preferences. The MT21A flashlight has a strobe function.

The Nitecore MT21A flashlight is powered by 2 x AA batteries. The MT21A 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.
Accessories
