The EC300 is a peculiar light. When I first read about it I was surprised: somehow the idea had never occurred to me to combine a normal quad emitter light with an RGB emitter in the center. The more I thought about it, the more interested I was. What I was most intrigued by was the fact that these were emitters, not aux LEDs. Well, with it in hand, it certainly delivered.

Package quality.

Skilhunt packaged the EC300 quite nicely in a stylized retail box, along with some accessories. The light is held in a little vacuum formed tray, with the accessories and manual stashed underneath. Nice and premium for a premium little light.

• 5000 MAh Skilhunt 21700
• Two spare o-rings
• USB-C cable
• Lanyard
• Pocket clip
• Manual
• Pouch

In a word, it’s excellent. The light feels great, it is a very nice size that stacks up against many of my 18650 lights. The pocket clip permits mostly deep carry, though the lip could be a little bigger. The tailcap has a hole for a lanyard that I opted not to install, and has a little recess, in the end, should you wish to place your thumb in it. For me, it was not very well located, but maybe that’s just my hands.

The EC300 uses a side electronic switch that is nicely situated and easy to press, however a tiny bit mushy. It also has an LED under it to indicate charge status which is easy to read and can be used to locate the light. The light has an internal USB-C charge port which is covered by a rubber cap. Uniquely, the cap is secured by a rubber ring that runs around the head of the light to prevent it from fatiguing where it attaches. Clever! The light can tail stand just fine, and the cooling fins on the head have a flat spot to prevent rolling.

The light is excellently built, barring one issue I’ll come to shortly. The knurling is very nice, grippy enough to stay in your hand but not so aggressive it becomes an issue. Made of aluminum it has a gray matte anodization, with light gray accents around the switch and optic. The threads are square cut and come factory lubed, however, when unscrewing the tailcap the pressure from the spring results in them binding and grinding against each other. 

I did have a fairly significant issue with the unit Skilhunt provided, where a portion of the diffused coating on the optic was missing. Upon opening the lens, there was some sort of liquid or lubricant trapped between it and the optic which had eroded the coating. While not a fatal error, this is certainly something that consumers should be aware of. Skilhunt is providing a replacement at no charge.

Skilhunt offers a free replacement of any defective parts within 15 days, and within two years of purchase free repairs. A limited lifetime warranty is in place where they will charge for parts/shipping and not service for repairs.

The unique feature of this light is its LED configuration, combining a quad TIR optic with a RGB emitter in the center behind a crenelated bezel. The TIR optic with a diffusion coating on it produces a very nice balanced beam which is extremely floody. There is no defined hotspot and blends very nicely. The tint on the SST-20 LEDs is excellent and makes for a very pleasant beam.

The RGB emitter certainly impressed me. I have to admit I was expecting something more similar to the aux lights that come on some flashlights, however it is a bonafide emitter. You certainly do not get a lot of output or throw from them, however it is certainly usable for most tasks a light like this is suited for. The red light in particular is very useful at night to preserve night vision. The one issue is that due to the placement of the emitter in the center, the red, green, and blue portions are slightly off and result in an almost “square” beam as they interact with the optic.

Opple measurements were taken at 6.3 meters on high.

Flashlight size comparison with its competition

The light uses its own custom UI built by Skilhunt with multiple main modes and “submodes.” While it has a great deal of complexity and could (and should have on some other lights) be replaced by Anduril, in this particular case with the RGB emitter I think it was the right call to stick with their own. That being said, some consistency between UI’s within Skilhunt’s own lights would be great to see.

The EC300 is powered by a single 21700 cell, Skilhunt shipped it with their BL-250 5000 mAh battery which was used for these tests. The light has an internal USB-C port for charging which has addressed one of my biggest complaints when lights do this externally, which is the rubber boot. They have designed a rubber ring that runs around the head of the light to prevent the fatigue that happens at the traditional “pin” installation of one of these protectors. While I would prefer it be installed in the threads internally behind an O-ring, it is a very nice solution to the problem. 

The BL-250 battery is a protected cell, however one of my Molicell P42A 21700 cells fit without issue. There is some slight side-to-side rattling that takes place, but never enough to dislodge the contacts. Internal charging takes place at 2A as I measured and was around 3.6 hours to fully charge the 5000 mAh battery. The light can also act as a powerbank with actually compliant USB-C behavior, and discharges at 2A as well.

Lumen measurements

 Lux readings were taken with a Triplet LT68 data logging meter, as were candela measurements. Lumens were calculated using an integrating tube I built, calibrated with a Convoy S2+ that had been sent to a calibration lab for a report.

Mode	Specs	Lumens @turn on	Lumens @30 sec	Lumens @10 minutes
Low	5	13.1	12.9	12.9
Medium	150	58.9	58.8	58.3
High	420	452	445	440
Turbo	2300	1165	1070	369.5

Battery Life: Runtime graphs

Runtimes were measured using the BL-250 5000 mAh 21700 from Skilhunt, fully charged before each test

Mode	Specified runtime	Measured runtime (ANSI)	Time till shut off
Low	270h	16h+	16h+
Med	16h	16h 2min	16h 2min
High	6h	5h 45min	5h 45min
Turbo*	3h 42min	3h 20min	3h 39min

ANSI FL1 standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries.

Peak beam intensity and beam distance measurements

Lux was measured at six meters using my luxmeter and converted to candela and throw distance using known formulas.

Mode	Specs	Candela measured	Meters	Yards
Low	–	90.8 cd	19.1m	20.9 yd
Medium	–	504 cd	44.9m	49.1 yd
High	–	1080 cd	65.7m	71.9 yd
Turbo	6300 cd	6696 cd	163.7m	179.0 yd

Extra info: Peak beam distance according to ANSI FL1 standards: The calculated value of distance in meters at which the flashlight produces a light intensity of 0.25 lux. (0.25 lux is about the brightness of a full moon shining on an object). Columns Meters and Yards show rounded numbers

Beamshots were taken with a Canon EOS Rebel at 1/15 seconds, F5.6, ISO 1600
