Elegant Design

The MT21A is a streamlined version of the MT2A. Its updated styling offers machined grips and smooth, elegant lines. An advanced XP-E2 R2 LED is powered by two AA batteries and intelligent memory circuitry that gives you the best in usability and efficiency. In the past, AA flashlights have had to sacrifice power in the name of practicality but, thanks to ever-improving technologies, Nitecore is able to get more and more impressive outputs from this widely available and inexpensive power source.

Ready for Anything

On top of its brilliant output, the MT21A is also rugged and dependable. A hard anodized aluminum body is perfectly fitted with O-ring seals that give this light an IPX-8 water resistance! That means up to 30 minutes submerged in water two meters deep! The body maintains a slim profile making it easy to carry in any backpack, glove compartment, or emergency prep kit. The MT21A utilizes a tail-switch for activating the light and cycling through its output modes. Nitecore included a 15 lumen low mode for up close illumination, as well as a 60 lumen medium, and 130 lumen high mode. The 260 lumen turbo mode is ideal for long-range lighting thanks to the MT21A's smooth reflector which has been engineered to project light down range.

Choose Your Task

The MT21A offer two separate operating configurations depending on your needs. When the bezel twisted to the left, the MT21A is in its user-defined mode, allowing you to cycle through its four output modes, as well as a blinding strobe by rapidly depressing the tail-switch. The light will turn on its most recent mode. With the bezel twisted all the way to the right, the light is in its turbo mode. Depressing the tail-switch when in turbo mode will automatically engage the light's brightest setting. Turbo mode is perfect when you know you'll need instant access to the light's full power - when you're searching through a field, or looking down a trail. The user-defined mode is more useful in closer situations, when you may want to adjust your brightness repeatedly as you look through a tent or hallway.

Long Throw
April 29, 2020
Very long beam that isn't too tight to see objects outside the beam. Nice usable features, high, low etc. Perfect for an under 200 yds weapons light.

good light

This is another good light from Nitecore. It is bright and throws a good spot over long distance. Good price as well.

Really good start in the AA light family
November 12, 2016
Good fit in the hand with a tail switch. Rotate the head to jump to high power. Has all the standard light levels at this size(high,medium,low,flash SOS,beacon).
Great tight beam that really reaches out there. Good lower power level for walking. I keep mine on low and a quick twist of the head and pow almost a light saber.

Probably the Best Choice for AA Tactical Flashlight
February 15, 2016
I was skeptical about buying a $40 (list) flashlight, but needed to replace my wife's 2 AA Maglite, due to the batteries being frozen inside. Research revealed very positive reviews and tests of the Nitecore MT21A, including long battery life, a solid penetrating beam, and a good choice of brightness settings. I purchased two, one for my wife and one for me. Our main use is for travel, as an emergency flashlight. The bright beam would help us navigate a dark or smoky hallway. The long battery life on low settings would help us if stuck on a cruise ship with no power for a few days. And being compatible with AA batteries makes it easy to transport or purchase spare batteries without running afoul of TSA regulations. I keep lithium batteries in the light and a set of 4 alkalines in the plastic Tenergy battery case.
  • Brightness, battery life, nicely machined, uses common AA batteries.
  • Cannot use rechargeable lithium AA batteries. (Not a big deal, as AA batteries are easy to find, easy to transport spares).

Definite Improvement over Previous Generation (MT2)
December 9, 2014
I had previously ordered and use two Nitecore MT2 flashlights as an inexpensive, AA battery powered, everyday carry light. The MT2's have served me very well. When I went to order a third MT2, it had been replaced by the Nitecore MT21A. IMHO both models are solid every day tactical/safety flashlights with the MT21 an evolutionary improvement over its predecessor.

The main differences I noted are: MT21A has a larger lens diameter, a brighter light, and a bigger center spot. Recommend, especially when on sale. Only reason for 4-Stars is these are not "be all, end all" flashlights, but are reasonably priced and an excellent value.
  • Price, brightness, size, AA batteries,
  • None for their purpose.
1 Question & 1 Answer
from Punta Gorda FL asked:
May 26, 2014
Can this light stay in the strobe mode, so when I ever turn it on or off it will be in strobe mode?
1 Answer
Yes, with the bezel kept loose and the tail cap clicked in strobe mode. The MT21A can be turned on and off in strobe mode.
