Acebeam E75 Review (Best Flashlight of 2023 so far!)

Subscribers to the channel may have noticed I have been slowing down in reviews a bit, and part of that’s being really selective in what I review. When I saw the Acebeam E75 announced, I knew I wanted to review it, well and let’s just say, I’m not disappointed. The size, LED’s (Nichia 519A available) and UI make this a win in my book, maybe the best of the year so far. Thanks to Acebeam for sending this to me to review, any sales or discounts that are available will be in the description below.

Packaging & Accessories

I will quickly go over the packaging and accessories that came with my light and then get to what you really want to know. It’s a nice full-color black box with the outline of the light on the front. The side gives a few highlights and the specs of your model, and the back more detailed stats. My light came with 2 spare orings, a charging cover, a generic lanyard, USB-A to C charging cable, and an Acebeam branded 5000mAh protected 15A 21700 li-ion battery, and the standard paperwork. 


Construction & Design

The light is currently being offered in aluminum, anodized in 4 colors, Black, Gray, Blue and Dark Green, and I have the dark green model here. Interestingly the photos on Acebeam’s website don’t show a blue model, but 2 shades of green instead, a grass green which is what I have and a teal green seems to be what they are calling blue. 

The light itself has a flat tail, with a very strong magnet and easily holds itself horizontally on painted slick surfaces. The tail cap has nice functional straight knurling. Internally there are springs on both ends and threads on the tail are square-cut. 

The body tube and head are integral and made of one piece of aluminum. The tube has spiral unidirectional knurling. It’s fairly smooth and could be a little more aggressive in my opinion. 4 large flats are milled in to break it up. 

The e-switch has a black aluminum cover, with a clear plastic ring surrounding it. Underneath there are the 4 LED power level indicators. These are multi-color but all behave the same. They are green when the power is greater than 20% remaining, turn red under 20% and blink red when under 10% remaining. One interesting thing to note is the 4 green power level LED’s around the button are always illuminated. This isn’t a big deal during most operations but is less than ideal when in moonlight mode. I have been told there is a revision where the LED indicator brightness will be less. 

The charging port is opposite the button and has a good-fitting silicone cover. I’ll talk more about it and the pocket clip more in their respective sections. 

The front bezel has moderate crenulations that are reasonably sharp. Mine is glued in place and I would guess made of steel. The lens is glass and AR coated, below it is the quad optic and in my case the 4 Nichia 519a LED’s. 



The UI here is what I’ll call the standard flashlight UI. It’s one many other manufacturers use and is logical. From off, long press on the button to turn into firefly mode. A short click from firefly will shut it off, and a longer click from Firefly will turn it to low. When already on in the standard modes the longer click will allow it to cycle up through low, med1, med2, and high. Turbo is a double click and strobe is a triple click. Both Turbo and Strobe shortcuts work when the light is off too. To turn off from any mode it’s a simple short click. There is memory on the normal modes, and lockout that can be activated when the light is off by holding the button for 3 seconds, and the unlock is the same procedure. 



The lanyard attachment point on the E75 is on the tail cap, similar to a lot of other lights. It’s sufficient but nothing special. Let’s talk about the clip on this one though. It’s a little different design than I have seen on most other lights. It’s screwed on just under the charging port and runs most of the length of the body. It’s a dual-direction clip but neither is what I would say is great in my opinion. Both directions leave about 1” to 1.75” sticking out of your pocket both of which are more than I would like. With the diameter of this light and clip configuration for me, it’s not going to be an EDC in my front pocket. In a back pocket, it’s ok. There is no included holster which I would like for this size of the light, and something some of the competitor lights includes. 


Size & Weight

I measured the length of the e75 at 5.1”, the diameter of the head at 1.38”, and the diameter of the body at 1.04” on the flats. Weight with clip and battery 7.64oz, or 216.7g. Slightly heavier than the Olight Seeker 3 Pro at 7oz or 198.9g. 


Here are a few size comparisons with similar lights that I own. 


LED & Beam

The Acebeam E75 is available with 2 LED options, a cool white 6500k option that’s not specified officially producing a peak of 4500k, and a neutral white Nichia 519a option which is what I have here. On my Opple meter, I measured the Nichia 519a LED’s at 4701k tint and at a 98Ra (CRI). Both are excellent and my personal preference, there was nothing negative to measure with the DUV here either. PWM was not to be found here as it’s a constant current driver.


The beam shape coming out of the quad LED’s isn’t perfect. On my Nichia version, there is some flower petal effects going on, at about 5ft or further though these are very minimal and not something thats a big deal. What you do notice is that the spill isn’t round, but the center is fairly round. I would put this as more of a floody light than thrower, but not pure flood. 



Here is an output chat, and it’s nice Acebeam includes measurements for both LED’s not something all manufacturers do these days. Moonlight through High I saw numbers that were reasonably close to the claimed numbers at the 30-second mark (FL1 standard). Turbo on my homemade TexasAce lumen tube read low, and this is a trend i’m seeing above 3000 lumens. It’s something I’m going to have to investigate further. 


Heat & Runtime

Runtimes came in at what was expected for the most part. You can see that turbo starts stepping down at the 1-minute mark over the next minute before being at the 1000-lumen mark. Heat peaks at the end of the first step down out at the 1:33:00 mark at 54C .Starting in turbo and running to exhaustion ends at 4:10:00 which is pretty solid. You get 93 minutes of runtime on high of around 1000 lumens. Skipping turbo and going straight to high doesn’t yield much more only about 7 more minutes in high and 18 more minutes in overall runtime. Medium 2 lasted a total of nearly 7 hours runtime. The lack of a rubber grip here does make it a little toasty if you heat peak temps but it’s only after running for 90 minutes continuously, assuming you are not spamming turbo.



The E75 uses onboard USB-C recharging and I had no issues with any of the cables or charges I used. PD support was good. The included cell is a 15A cell model number IMR21700NP-500A, is a button top, long, and protected. I measured it at 75.29mm, and my longer battery from my brass E70 worked fine which is even longer. Most button-top cells should be fine here, but not the ones with dual pole contacts on one end. 

Charging time in my test took 3:10:00 from LVP at 3.009v to full at 4.134v. During this time charging speed hit a maximum of 2A with a pretty substantial ramp down beginning at the 2 hour mark. One note on the termination voltage. The 4.134v is when the lights voltage indicators went from red flashing to green solid. If you leave it plugged in it will trickle charge a bit closer to 4.2v. 



My conclusion on the Acebeam e75 is that it’s my favorite light of 2023 that I have tested so far. For me the combination of the slightly warm, neutral, high CRI Nichia 519a LED’s, solid beam pattern, and 21700 battery provides a long runtime, and it’s available in green, one of my favorite colors. It’s got an easy UI too without any negatives, and no proxy sensor. This is a form factor I like too, and it’s a step up over the Olight Seeker 3 Pro which has the cool white LED, proxy sensor, and a UI I’m not hugely fond of. 


The clip on the E75 isn’t my favorite, and it’s not going to be a front-pocket EDC for that reason. It also doesn’t come with a holster which is unfortunate, but it does fit in the Olight Seeker 3 holsters. You could also argue it’s price might be a little high if you’re comparing it to something like the D4V2 which is a similar size and performance but if you’re comparing it to the Olight Seeker 3 Pro or Seeker 4 it’s in line with the competition. 


For me the pro’s outweigh the cons, and this ticks a lot of boxes for me for a general-purpose flashlight especially if you value high CRI, warm/neutral emitters like I do. It’s eays for me to recommend the E75. 

Nitecore P20iX Review (4000 Lumens, 4 LED, 21700, USB-C)

Today I have a new Quad LED light from Nitecore with the P20iX that produces up to 4000 lumens on a 21700 battery and it features onboard USB-C charging with Tactical and Daily modes. Thanks to Nitecore Store for sending this to me to look at and review.

Packaging & Accessories

Packaging is a step up, with a nice high quality box full of information. Inside the light is packed in foam with all the accessories underneath. It reminds me a bit of how Olight does theirs. Accessories include a branded lanyard, Extra Oring, USB-A to C Charging cable, Pocket clip, CR123A battery adapter, hard plastic belt holster and a Nitecore specific 5000mAh 21700 battery.



Machining on the aluminum light is good here, and the anodizing is high quality. The tail cap has a large off center mechanical on/off button that’s covered with a textured silicone boot. It stands proud making the light unable to tail stand. Your mode switch is a flat, textured area. This is flush, but protected by the outer rim of the tail cap. For me this was harder to find in the dark and hard to actuate with gloves on. 

The body has some tame knurling on it, the pocket clip attaches near basically the middle of the light in either direction. The head does not separate from the body. On the head you have a large antiroll ring to keep the light in place on it’s side. You do have a blue LED that’s built into the side of the light that’s used as a charging indicator, similar to the MH11 I reviewed earlier this year.  The charging port has a large silicone cover and it fits tightly. 

At the front the light has a short bezel that doesn’t stand out from the lens very far, it has 3 protruding areas each with a small ceramic balls in them, I presume for striking glass that law enforcement may use. I believe the bezel is a little different material due to it’s slightly different finish. The lens is glass, and underneath there is a custom quad silver reflective optic for the 4 leds. 


Size & Weight

I measured the length of the light at 140mm. Minimum width on the body at 25.4mm, maximum diameter on the head at 32mm. Weight with the included battery in the light and no other accessories is 191.7g. The light is IPX68 water rated and drop rated to 2M. 



The P20iX has a couple of retention options that come in the package. First is the lanyard which is primarily slip fit over the light or attached to the clip. The clip which is a press fit is fit down pretty low, which leaves a lot of the tail or the head of the light sticking up out of the pocket. This is disappointing to me personally. That said the plastic belt holster that the light comes with does a pretty good job if you want to carry the light on your belt or on a mole vest. The light clips in with the front bezel facing down. 


LED & Beam

THe light has 4 Cree XP-L2 V6 Led’s in cool white with a maximum output of 4000 lumens. The tint here is cool white, likely around 6000k or a bit higher. The beam is somewhat compromised in this quad. The hot spot is pretty round but it’s not a smooth transition in the spill and you do get some Cree Rainbow. The very outer edges are a bit rough. That said it’s hard to nice in real world use at distance. 


Heat and Runtime

For my Heat and runtime I ran the light with the included 21700 battery. The light will run on 2x CR123 batteries in the included adapter if you wish but you generally get less output and for a shorter time. With the 21700 on turbo the light lasted only 30 second before step down. This was disappointing especially since the heat during this time at least measured externally didn’t amount to much. Step Down was pretty significant as you can see from the graph. As the light continued to run heat pretty quickly increased though up to about 55C, at about 21 minutes. Thermals eventually regulated at about 25C for the duration of the runtime. The light went into it’s lowest mode after about 3 hours of runtime where it continued for another 2hr and 20 minutes for a total runtime of 5:20:00.

I did another runtime graph with comparing runtimes of the 4 highest output modes, Turbo, Highest, High and Medium. The 3 highest don’t have a ton of overall impact on output. Medium ran for considerably longer, a solid 8 hours without stepdown. 



The P20iX has 2 modes, a Daily mode which it ships in with 5 individual modes, and then a Tactical mode with 4 individual modes. To switch between them, you turn the light on, press and hold the mode button on the tail and unscrew the light. It will flash Once for Daily, or twice for tactical and then you screw the light back together for it to be remembered.


Daily mode is where I am using the light most. In this mode the light starts in the lowest output and goes up with each press of the mode button. It has memory so you can shut the light off and when it comes back on it will be in the previously used mode. This mode has outputs of 2,50,300,850,1700 lumens, and then to get turbo (4000 lumens) you hold the mode button in and it works in a momentary manner. Double click this mode button to go to strobe in momentary. 


Tactical mode is similar but it goes from highest output including turbo down, and only has the 4 brightest modes.



The light features a USB-C port on the side covered by a tightly fitting silicone rubber cover. I used the included 5000mAh 21700 battery to run my charging tests and found total charge time took 3hr and 54 min. Max charge rate I saw was 2A. The light will charge via USB-C PD without issue. While charging the battery in the light, it’s not possible to use the light at the same time. The LED on the side will blink when charging and go solid when charged. When a battery is inserted it will also blink the voltage. 


The included battery looks to be custom with a negative terminal on the positive end. It’s a long protected battery with a shallow button top. It fits in my Vapcell S4 Plus charger and works just fine there. Due to that length I wasn’t able to find another battery I had that fit this light



This is a pretty nice high power flashlight from Nitecore. I like that it has a pretty practical daily mode, and that it’s not all tactical. It’s an interesting choice to have Turbo be only in momentary in daily too. I do wish Turbo had more runtime before step down though.


The clip on belt attachment here works well, and I suspect that or in a bag is how most would carry this light. For me the pocket clip is super impractical due to it being so far down the light, and that’s a disappointment. 


I wish the battery was more universal, but this semi proprietary format with the protected batteries and positive and negative terminals on on side of the light seems to be the way most manufactures are going with their 21700 light that have onboard charging. It’s a disappointing industry trend in many enthusiasts minds. To be clear this is an industry thing, not just Nitecore. 

Overall this is a solid light for general purpose and has some nice tactical features without being 100% tactical. I can see this being a good option for many if you don’t mind the cool white LED’s or short turbo runtime.
