The Product
Today I’m taking a look at the EC4GTS that was sent to me by Nitecore. This is the newest light of their EC4 series, which all use two 18650 cells in a side by side arrangement. There are a few other offerings from competitors that have used this form factor, but it’s a relatively unique configuration and one that I’ve wanted to try out for quite some time. This particular model has an XHP35 HD set into a smooth reflector, and is controlled with two electronic side switches.
Spoiler
I’ve already said that this is a form factor I’ve wanted to get my hands on for some time, and I’m happy to finally have one. It’s a bit larger than I expected, but any light with this much capacity isn’t going to be tiny. The UI is good, the runtimes are great, and it fits into a jacket pocket quite well. I like this light a lot, and I really like having a light in my collection with such a unique form factor. |

Naming
When this light was announced, a lot of people were griping about the EC4GTS having less throw than the EC4GT. It’s a valid observation, but it’s important to note that having less throw doesn’t make this a worse light than it’s predecessor. There are now 5 models in Nitecore’s EC4 series, not to mention the similarly shaped SRT9. I put together the chart below to compare the models in this series by output and throw specs.
Build
Starting at the head of the light, there’s a very deep reflector protected by a smooth bezel. The two sides of the head are covered in deep cooling fins behind the reflector.
Flanking the fins, one side of the light is bare except for a serial number. The opposite side has the two backlit switches.
The body of the light is pretty nondescript - There’s some blocking on the two edges, but no knurling or other textures added. There are two long grooves along each of the flat sides of the light that provide a natural place for your fingers to rest while holding it. One side of the light has the product name and some brief labeling, which is the only printed text on the light aside from the serial number. The other side of the body is bare. I have to say, I really appreciate this design, and I’m glad Nitecore didn’t try to cram every empty space with a bunch of text like some other brands have been known to.
The tailcap has two long ears that notch loosely into the body of the light to help align it properly during installation. It’s held in place by a large thumb screw with angled knurling along it’s outer face, providing more than enough grip. There’s a hole in the screw that’s threaded with standard tripod threads. I’m not sure that this is the most convenient space for a tripod mounting hole, but I can see it being useful when coupled with a flexible tripod like a Gorilla-pod. Since the threads are standard, there’s a variety of other third party accessories that could be threaded into this hole as well. The sides of the tailcap both have single holes that can be used to attach a lanyard. The large flat area on the tailcap mean the light will tail stand quite well, although the design of the lanyard holes will prevent tailstanding when thicker lanyards are installed.
What’s Included
This light comes shipped in Nitecore’s standard packaging, a black and yellow card box. In addition to the light, this box contains a lanyard and a sheath.
Ergonomics and Retention
The flat shape of this light fits in a hand really well. Even though there’s not much knurling along the body, I found it quite solid and never felt like it was going to slide out of my grip.
The included sheath will hold the light either bezel up or bezel down. The flap secures the light with a velcro closure. On the back of the sheath there’s one fixed belt loop, one velcro belt loop, and a plastic D-ring.
Modes and Interface
This light has 5 output levels, ranging from 1 to 1800 lumens. Basic operation is dead simple - pressing the power switch will always turn the light on to the last used mode, and another tap turns it off. The mode switch cycles through the modes from low to high when the light is on. More advanced operations are as follows:- From off, long pressing the power button turns the light on in the lowest mode.
- From off, long pressing the mode button turns the light on in turbo. If turbo is left on for more than 2 seconds when started this way, it works as a momentary mode and the light will turn off when the button is released.
- Double tapping the mode button when the light is off starts the strobe/location/SOS mode. Subsequent presses of the mode button cycle through the three flashing modes, and the power button switches the light off.
- From on, holding the mode button momentarily activates turbo. The light goes back to the previous mode when released.
- Pressing and holding both buttons when the light is off enters electronic lockout mode. Repeat the action to unlock. The light turns on when unlocked.
- When on, press and hold the power button to turn off the light and activate the location beacon. The LED beneath the switch will flash every 2 seconds.
- Tapping the mode button when the light is off will indicate the cell charge - 3 flashes for over 50%, 2 flashes below, and 1 flash if the cells are nearly drained.
Light Quality and Beam
The XHP35 HD used in this light is cool white. Nitecore claims a maximum output of 1800 lumens from this LED. This emitter is not as large as the XHP50 or XHP70, which means the light is still reasonably throwy when coupled with the large smooth reflector. The spot of the beam is a great, pure white. The corona and spill show a bit of tint shift, but I didn’t find this distracting in real use. Even though this is a throwier light, I find it comfortable enough for general hiking use as well. I don’t think this beam would be best suited for close up tasks, but there are quite a few diffusers available if you’d like to extend its functionality.
Power and Runtime
Nitecore provided two of their NL1823 2300 mAh cells for testing of this light. Note that cell capacities up to 3500 mAh are currently available, and higher cell capacities will give longer runtimes than shown in the graphs below.
Summary
Pros:
- Indicating switch and battery check
- Great form factor - unique, compact, and solid.
- Amazingly stable runtimes
- Great UI with shortcuts to highest and lowest modes from off, as well as momentary turbo from on and off
Cons:
- Cell polarity stickers could lead to confusion about supported cells
