Skilhunt EC300 Flashlight Review

Skilhunt EC300 Flashlight Review

Skilhunt has released the EC300, a very interesting flashlight that offers USB-C charging, powerbank capability, High CRI, and RGB! Read on!

Official Specs and Features

Here’s a link to the Skilhunt EC300 flashlight product page.


As far as bodies go, there’s just this one grey option. I happen to love this color though, so that’s perfect. There are two emitter options available: CW (6500K) and NW (4000K, High CRI).


The price ranges from $66.90 (CW without 21700) all the way up to $80.90 (NW with battery, as seen in this review.) The Skilhunt EC300 flashlight is available from Skilhunt directly!

Short Review

You might have seen me gushing about this light before… I love it. I love the output, primarily – the 4000K High CRI Luminus SST-20 emitters are great. I love that it’s a quad (I love quads!). The user interface is great. I love that there are secondary emitters and that they’re in the center and not to the side. USB-C charging is fantastic and works great. The powerbank feature works very well too! All in all, this is just an extremely solid light! It even carries well for a 21700-sized light!

Build Quality and Disassembly

Skilhunt EC300 flashlight

The build quality of the Skilhunt EC300 flashlight is fantastic. That’s not unusual for Skilhunt though; they make solid lights.

Only this grey finish is available, but that’s alright because this grey color is great!

I also like that the grip area isn’t aggressive. It’s plenty.

The head has “cooling fins” but really more of a design feature than actual cooling fins, I would guess.

Here’s the tailcap.

That tailcap has a nice beefy spring and no magnet.

The head has a coiled wire too, but I don’t think it’s a spring.

The bezel unscrews easily. I didn’t check, but I think that’s a standard quad optic. As you can see, it’s slightly frosted, which means this will be a more floody light. I will probably swap this with a narrow optic, because a quad in general will give enough flood, and a narrow optic will tighten it up just enough. Someone in the comments can let us all know if SST-20 emitters play nicely with narrow optics!

Size and Comps

115mm x 29.5mm (head diameter) x 28mm (body diameter), and 71.2g without the cell.

If the flashlight will headstand, I’ll show it here (usually the third photo).  If the flashlight will tailstand, I’ll show that here, too (usually the fourth photo).

Here’s the test light with the venerable Convoy S2+.  Mine’s a custom “baked” edition Nichia 219b triple.  A very nice 18650 light.

Also seen above is the light beside my custom engraved TorchLAB BOSS 35, an 18350 light.  I reviewed the aluminum version of that light in both 35 and 70 formats.

Retention and Carry

First is the pocket clip. This is a standard two-way friction fit pocket clip.

Skilhunt EC300 flashlight pocket clip

Being a two-way clip, it should be no surprise that it connects only on one end. In this case, the tail end.

The clip provides a nice and secure attachment, and fairly deep carry too.

Next up is the lanyard, which attaches through these two holes in the tailcap. It seems like the tailcap is longer just to accommodate this lanyard bumpout. I’d happily take a 2mm shorter light and just attach the lanyard elsewhere. But this works very well.

There’s no pouch or magnet or anything else.

Power and Runtime

The Skilhunt EC300 flashlight runs on a single lithium-ion cell. If you go for the package, you’ll get the 21700 seen below, which is a 5000mAh button top. It’s a fine cell.

The cell fits into the EC300 in the usual way – positive end toward the head.

Here are a few runtime graphs.  Note that Skilhunt does spec both the CW and NW output – CW gets much higher lumen values, but the NW provides High CRI.  That’s basically the tradeoff.

The Skilhunt EC300 flashlight has built-in charging, too. That charging is by way of a USB-C charging port in the head.

The charging port cover is held in place by a collar ring style connector. When pushed in, the cover seems very secure.

A cable is provided. It’s USB to USB-C.

USB and USB-C both work just fine. Charging looks very good, at over 2.5A for both USB and USB-C connection. Total charge time is under 3 hours, too. When the light is charging, the switch indicates in red. When charging is complete, the switch turns blue.

One more feature of the Skilhunt EC300 flashlight is that the USB-C port can be used as a powerbank! You’ll need to provide your own cable for this feature. It works quite well, providing over 2A at over 5V for over an hour. The output shut off, and I manually restarted it (you may need to loosen and retighten the tailcap to let the light know you want more), and then it carried on at over 1A for a while. Rinse and repeat at 0.5A, and you can drain the cell down to around 3V before it will go no further.

^ Claims seem to be for the cool white version, and not ANSI standard readings.

Pulse Width Modulation

Fortunately, the Skilhunt EC300 flashlight does not use PWM in any mode.

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  Also, here’s the light with the worst PWM I could find.  I’m adding multiple timescales, so it’ll be easier to compare to the test light.  Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, with is 50 microseconds (50us).  10ms5ms2ms1ms0.5ms0.2ms.  In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line.  I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too.

User Interface and Operation

The Skilhunt EC300 flashlight is controlled by a single e-switch. This switch has a backlight function and can light in red or blue. While the switch is transparent, it has an interesting design pattern printed (?) in the center. It’s another thing to like about the EC300! Not a functional improvement, but a nice touch.

The switch is proud and the action is good.

Here’s the switch lighting in blue.

The user interface could be a bit daunting, but it’s very straightforward when you get used to it. It’s also very logical and provides access to low from off, which is as close to a requirement from a user interface as I have.

Here’s a UI table!

State Action Result
Off Hold Low (Memory between L1 and L2)
L1 or L2 Hold Iterate between L1 and L2
L1 or L2 Click 2x Switch to RGB group
RGB Group Hold RGB advance (Red > Green > Blue)
RGB Group Click 2x Switch to L1/L2 group
Off Click 4x Lockout (Three blinks of main emitters to confirm)
Lockout Click 4x Unlock to Low group (memory, can be L1/l2 or RGB)
Lockout Click 2x Iterate lockout indicator^
Lockout Hold Momentary Output (Appears to be approximately L1)
L1/L2 or RGB Group Click Off
Off Click On in “Main Group” (Mode memory M2/M1/H)
Main Group Hold Mode advance (M2 > M1 > H)
Main Group Click Off
Main Group, Off, or Low group Click 2x Turbo Group (T1/T2)
T1/T2 Hold Iterate between T1 (higher) and T2 (lower) output
T1/T2 Click Off
T1/T2 Click 2x Main Group (memory output)
Main Group, Off, or Low group Click 3x Strobe Group (with memory)
Strobe Group Click 3x Previous Group (T1/T2 or M2/M1/H, depending on how you accessed Strobe Group)^^
Strobe Group Click 2x^^^ Strobe Advance (S1 > S2 > S3 > S4)†
Strobe Group Hold No result

^ Lockout indicator blinks a red switch every 2-3 seconds.
^^ Aside from just general mode memory (which you know I don’t like) this seems to me to be the only place where you may need to immediately remember what mode you were in so you have the experience you expect. However, the difference is getting the two highest white outputs, or the three main white outputs – it won’t be that dramatic even if you don’t remember. Also note that if you accessed the strobe group from off, triple-clicking will not return to off. For continuity, it should! In fact, if you accessed strobe from an off state, a triple-click sends the light to the Main group!
^^^ Seems like the strobe group is the only group that isn’t advanced by a hold. Since there’s no hold anywhere else into or out of Strobe, I am not sure why that user interface continuity wasn’t maintained here.
† Strobes are like this:

S1: Disorienting strobe of White (turbo, ish)
S2: SOS (main white, some mid-High output)
S3: Red beacon (1Hz or so)
S4: Fast blink of red then green then blue

LED and Beam

Skilhunt has smartly offered a CW and NW option in the Luminus SST-20. I have to say, the SST-20 sort of sneaks up on you as being great. Particularly this 4000K version – it’s really, really good.

Skilhunt EC300 flashlight emitters

One more thing to like about the EC300 – this toothed bezel is easily removable (by unscrewing!)

LED Color Report (CRI and CCT)

Same mode order as you’ll see below. First, the 7 white modes, lowest to highest. Then Red, then green, then blue. I find the blue to be quite intense!


These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.

Tint vs BLF-348 ( 219b version) (affiliate link)

I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.

I compare everything to the 219b BLF-348 because it’s inexpensive and has the best tint!


What I like

  • Great build quality
  • Red, green, and blue emitters in the center of the mcpcb!!
  • USB-C charging works great
  • Powerbank feature works very nicely, too.
  • 4000K High CRI Luminus SST-20 emitters are so good (and the claims made about it by Skilhunt are accurate)
  • There’s a neat design on the switch
  • Ability to hit the Low group from off
  • Consistency in the “off” access – From any on state, click turns the light off

What I don’t like

  • RGB each have just one output (and it’s fairly high)
  • A few user interface inconsistencies that can make some modes a bit awkward compared to how you’ve accessed other modes (ie inconsistency of “hold” action)
  • Price – at $80, it’s not inexpensive

    1. “The brightest mode on a good flashlight is usually called “Turbo” mode. In Turbo mode, the flashlight will over-drive the LED to give you extra brightness for a minute or two when you really need it. This usually generates a lot of heat, but once the light has heated up all the way there’s nowhere else for the heat to go. At that point the light will step down to a lower brightness (usually to High mode) so that it doesn’t overheat or burn its user.

      A lot of users don’t like this feature or find the advertised brightness misleading. “Why can’t I buy a flashlight that doesn’t step down?” The reason is that a light that doesn’t step down cannot have a Turbo mode. Would you rather have a light that can only do 500 lumens because that’s what it can sustain without overheating? Or, would you rather have a light that can sustain 500 lumens and do 2000 lumens for a minute or two at a time?

      If you want a light that doesn’t drop in brightness after a minute or two, the best solution is to buy a light that has the brightness you want on High mode, and then use High mode because it won’t step down. Then, when you need some extra brightness you can step up to Turbo.

      It’s also worth noting that it takes 4x the lumens to be 2x as bright, so most Turbo stepdowns are not as visually significant as you would think based on the lumen numbers.” – written by u/TacGriz
