Details:
The Nitecore EC23 is a high performance compact flashlight utilizing a Cree XHP35 HD E2 LED to emit a scorching 1800 lumen output.
One of the brightest flashlights of its size, the lightweight and compact EC23 can be easily stored in pockets, packs or bags for quick access to light anywhere you go.
Powered by a single IMR 18650 battery, the EC23 has a max runtime of 330 hours and a max beam intensity of 16,200 making it perfect for outdoor use and everyday carry.
The EC23 can also be powered by normal 18650 batteries, 2x CR123A or 2x RCR123 batteries in a pinch. (We recommend using the Nitecore IMR 3100mAh 18650 battery which can be added via the drop down menu.)
An innovative all-in-one control switch located on the side of the flashlight allows easy one-handed operation of five brightness levels and three special modes.
The addition of a tailstand provides the ability to light up an area and frees up hands for working or maneuvering.
A combination of features such as Advanced Temperature Regulation which regulates output and adapts to the ambient environment and an IPX8 rating ensure the EC23 is a premium EDC flashlight for all-weather applications.

Comparism and teardown:

Size compared to other 18650 lights the G35 compared to my other lights the biggest but not heaviest

Beam color is cold around 6500K with a Cree XHP35 HD E2, the beam is a mix of flood and throw for a normal 18650 EDC but it shows a pronounced donut hole with tint artifacts

The reflector has no imperfections and is free of dust particles that can be seen when the light is off
The lens is AR coated

Light color compared to other lights
from left to right the lights get warmer, picture taken @5000K camera setting
left Nichia 5000K, Nitecore EC23, XPL HD 6500K

The lights head is heavily glued with red locktite

The light has a tail cap with two holes for a lanyard
The light stands on the tail

The head has a diameter of 25.4mm 19mm visible reflector

The light can be run by one high drain 18650 battery which is included


the battery is in the light insulated with Kapton tape

The light can be physically locked out by twisting the tail cap or tube to the head

The Head

The tube light has 25.4mm diameter

The light is waterproof, the tail cap and head o-rings and threads are lubed

.

Tube and Tail

The tail cap is fully anodized and has a spring board glued in it

the tube is build for one battery, my Klarus High drain batteries with 69.7mm barely fit, it’s hard to screw down the tail cap with it, the spring gets fully compressed and the battery gets pushed pretty hard to get the tube to make contact

The tube threads are square cut and fit nicely

.

Driver and Battery

The light shows no PWM in any mode using falling water drops

The battery is a high drain with 2500mA, I tested it with about 2500mAh under 1.5A discharge and 39mOhms in my Miboxer C4-12

The light has a some mass to absorb and surface to spread heat, the tube is relatively thick

The light steps down at 61°C head temperature

Activating turbo after the step down again reaches a max. head temperature of 70°C, the light immediately steps down when that hot

the light uses a single solid contact on the driver and a big thick copper alloy spring in the tail

The mode spacing is OK, the moonlight has about 1 lumens

The light uses a boost driver for the XHP35

Tail current for modes

M 13mA
L 120mA
M 580mA
H 2.4A
T 6.5A

The side switch status LED shows the battery level when the battery is connected it blinks 4 then 2 times for 4.2V
Also when the battery gets low it will start to flash to indicate to charge the battery

Modding:
It is very hard to get to the LED as the lights head is glued, I will try to change focus to eliminate the donut hole and put a NW LED in it

User Interface

The light has a strange UI
I would describe it as sort of forward clicky with a momentary Turbo
short click for on and off
from Off 0.5s long press for moon

from Off 1.5s to get to turbo
within 3 seconds after switching on hold the button to cycle modes, this mode gets saved
after the light is on more than 3 seconds a long press goes into momentary turbo, a short press switched the light off
triple click to get into strobe from on or off, hold button longer than 1 second to get to the special strobe modes SOS and Beacon

.

Conclusion

Positive:

- mechanical very good production and engineering
- solid head, DTP MCPCB
- AR coated glass lens
- proper LVP and low battery warnings
- low resistance copper alloy springs
- good moon mode and mode spacing
- good thermal management gets a lot output for some time
- good high drain battery with 39mOhms and 2500mAh

Neutral:

- the UI is strange but if you are used to it is useful, just changing normal modes after the light is on is not possible, you have to turn the light off for a moment, but it has then a momentary turbo

Negative:
- Donut hole in the beam, so reflector focus is not right
- head is glued, so hard to fix donut hole or change to NW emitter

Thanks for the good review. A beam like that would not be acceptable to me.

You may want to change ‘Klarus’ in the title to ‘Nitecore’ ?
