Nitecore EC20 LED Flashlight

Compact and Capable

The Nitecore EC20 LED Flashlight is a powerful and highly portable LED flashlight that is perfect for every-day-carry. Measuring in at 5" long and weighing less than 3 ounces, the EC20 is a pleasure to hold. Constructed from aero-grade aluminum alloy with a military grade hard-anodized finish, the durable EC20 will stand up to most impacts and the wear and tear of frequent use. The EC20 is IPX-8 waterproof, meaning that it can be submersed under water up to 2 meters with no problem. The next time it rains while you're out or you accidentally drop the light in a puddle, no need to worry.

Lighting Technology

The EC20 is equipped with the latest CREE XM-L2 (T6) LED, which can produce an extremely bright 960 Lumens of illumination while on its highest output. In addition to its highest output, the EC20 features three dimmer brightness levels, as well as a trio of special tactical outputs including a Strobe function, a S.O.S. Mode, and a Location Beacon, all of which are accessible using the light's intuitive side switch. The light is equipped with a high-efficiency regulation circuit that will provide constant output and prevent any possible dimming. A memory function allows you to return to the most recent output before you turned it off, so there are no surprises, while out in the field.


The EC20 is capable of running on either a pair of CR123A batteries or a single 18650 battery. Maintaining battery life is a breeze, as the EC20 features an integrated power indicator in the side switch that will flash in different patterns to indicate remaining charge. When power levels reach 50%, side switch will flash once every two seconds. When power levels are low, the side switch will blink quicker. Each time the batteries are inserted, the side switch will blink to indicate battery voltage. Reverse polarity protection ensures safety against improperly inserting batteries in the EC20.

My second EC20. My favorite flashlight
May 10, 2022
I purchased a second Nitecore EC20. It is my favorite flashlight. It has the best features, is easy to use and very Bright.
Battery Junction is the only source i could find for this model that has been discontinued by Nitecore. Battery Junction was the only place I could but the EC20 and an NO 1823 battery which was the Nitecore original battery for the EC20.
I have purchased multiple batteries through their Web site..

This light and all Nitecore lights are pure garbage.
July 20, 2018
Battery Junction is great, this light is not. Both of mine have failed as have all other Nitecore lights that I own other than 1. All of my higher end lights like S------E and such are still kicking. Many that are much much older and have been used way past what they are designed to handle. I too had a positive response when using these lights like many of the reviewers but trust me when I say they are way too fragile and prone to failure whether used light or used hard. My family uses flashlight like some people use their TV remote and in no way shape or form should you count on the EC20. Save up and get a real flashlight especially if you need to count on it.

Mighty White Light
November 28, 2017
This little gem gets a perfect ten! Size is just right for a guy's pocket, the switch is where it should be, and the light is a just-right white with great spread. i have a collection of LED flashlights, and this is one of my favorites. The only thing that would make it better is if it were $24 instead of $34.
  • Side switch, color temperature, solid case
  • You can get larger, brighter flashlights for about the same price.

What are the differences between the EC20 and the P12 that I currently own? Other than the price.
1 Answer
The P12 is slightly longer with a tail switch and side switch, while the EC20 has only a side switch. Also, the P12 puts out 950 lumens and the EC20 outputs 960 lumens, which wouldn't be noticeable to the eye.
