Before You Buy

If you are in the market for a compact, yet powerful EDC light you want to make sure you purchase the best one. With how many choices there are it can be hard to pick just one. Before you purchase your light you want to narrow down your choices by looking at certain key features. With a compact light, size is important. You want something small enough to carry, but big enough to fit comfortably in your hand. How many lumens the light can emit is also important, you need enough light to get the job done. Not all jobs will require a lot of light. Look for a light that offers different output modes so you have the ability to select the right amount of light for the task at hand.

Nitecore EC4S

NiteCore EC4S 2150 Lumens XHP50 Flashlight with LumenTac Battery Organizer

The Nitecore EC4S is the upgraded version of the original Nitecore EC4. The biggest upgrade to the Nitecore EC4S was the quad-core CREE XLamp XHP50 LED. This upgrade allows the compact light to emit a maximum of 2150 lumens. While the Nitecore EC4S can use four CR123 batteries, for the best performance and run times you need to use two 18650 batteries. With the two 18650 batteries, the light emits the maximum 2150 lumens for 45 minutes compared to 30 minutes with the four CR123s.

Using Unique Integrated Technology the EC4S is extremely lightweight and compact. The die-cast body is a single piece made of aero grade aluminum alloy there is no separate battery compartment. Molten aluminum is injected into the mold cavity using high pressure to create a body that is 200% stronger than an ordinary light. To make the Nitecore EC4S as compact as possible the two 18650 batteries sit side by side with no gap. A rear thumb screw lock gives the light the ability to connect to a tripod.

Nitecore EC4S Features & Benefits

User Interface


Featuring a dual switch user interface the Nitecore EC4S offers five brightness levels and three special concealed modes. The bottom switch is used to power the light on and off, while the top switch is the mode switch. Pressing the mode switch while the light is powered on allows you to cycle through the various brightness levels. To enter into the special modes you must press and hold the mode switch for over one second repeatedly until the desired mode is found. Ultra low and Turbo mode can be directly accessed when the light is on by pressing and holding either the mode or power switch. To enter lockout mode press and hold both switches for over one second.

Battery Indicator Light

The Nitecore EC4S features a battery indicator light to alert users to the lights current battery power. To activate the feature simply press the mode switch while the light is powered off. The blue light will flash in various patterns based on battery levels. The light will blink three times when the battery level is over 50%. When levels drop to below 50% light will then blink twice. When the battery is close to being drained the light will begin blinking once.

Overheat Protection


With the ability to emit a maximum of 2150 lumens overheating is a real concern. The Nitecore EC4S offers extreme cooling performance to help prevent the light from overheating. Low thermal resistance and the Nitecore EC4S structural integrity allows the heat to be distributed quickly and evenly to the surface of the light. The cooling fins provide a 30% larger cooling surface compared to ordinary lights. The ATR Intelligent temperature control keeps the cool both inside and out by adjusting the output based on the lights internal temperature.  The light will get warm, but it will never get hot even working long hours on high outputs.

Social Proof

I have spent hours reading through Nitecore EC4S reviews. Most of the reviews that I have read talk about how amazing this light is. Most reviewers mention the die-cast body as it adds to the durability of the light. Several reviewers talk about how bright the light is, especially for its compact size. Even with all of the positive reviews, the Nitecore EC4S isn’t without its flaws. One thing that a reviewer took note of was the tail cap threads. They were a bit tricky to get lined up just right. The other concern from a reviewer was the irregular hot spot pattern. Neither one of these concerns is enough to prevent you from buying the light.
