Acebeam E70 Mini Review(Triple Nichia 519a, 2000 Lumens, 18650)

Acebeam has a new light, in the E70 Mini, it’s a smaller version of the E70 but this time it’s running on an 18650, and runs triple Nichia 519a LED’s. The Nicha 519a LED is the new hotness in the enthusiast flashlight communities. It’s the successor to the popular Nichia 219b, but the new version is brighter, and more importantly, has become known for being very neutral and rosy if you want. Thanks to Acebeam for sending this to me, and these thoughts and opinions have not been influenced by anyone.

Package & Accessories

The E70 Mini arrived in a white retail package with a clear window showing the light inside. Pretty minimal info on the package, but it is surprisingly compact. Inside the accessories and extras included, a 3100mAh button top protected 18650 battery with onboard USB-C charging, Short USB-A to USB-C charging cable, Acebeam Lanyard, spare o-rings, warranty card, and manual. 


Construction & Design

The E70 Mini for all intents and purposes a scaled-down version of its larger brother the E70 with a few minor exterior changes. For now, it’s available in aluminum that’s anodized matte black. It’s a premium feeling of anodizing, and the inner tube is the same blue aluminum we have seen on other E70 versions and the RX Ryder. I would expect to see different colors or materials of the E70 Mini at some time but for now just aluminum.


The tail features the same style of a flat metal button over the eswitch, it has a shiny finish that matches the clip well and is probably made of stainless steel like the clip. It has some interesting mounting options at the rear I will cover a bit later in the review. The light will tailstand too but it’s not magnetic.

The body tube has the same milled pattern as the E70, with a similar inner liner of blue aluminum and at the top 6 slots for 1 x 6mm tritium tubes, where the head has slots for 6 more. Threads on the body are square cut, and anodized. Inside you can see the spring at the tail, and head. Longer batteries or protected batteries are required, here, unprotected flat top 18650s are just too short to make contact. The bezel on the head is made from the same steel as the clip and rear switch. It has a crenulated bezel but it’s not sharp. The bezel does unscrew pretty easily too which should make maybe dedoming those LEDs (A popular thing to do with the Nichia 519s) possible without too much effort. The TIR optic sits behind an anti-reflective coated piece of glass with an o’ring keeping everything watertight.



The rear of the light has 3 wing like parts spaced out evenly around the light, and each is unique, you have the stock clip that comes on the light, with spacing that’s slightly wider than the more standard “Steel Flame” style clip, but to the left, there are threaded holes that fit the standard “Steel Flame” sizing, and then the third has larger unthreaded holes for the lanyard. 

The clip itself is stamped steel but slightly curved and uses a milled piece to make it stand out a bit. I found this to be a fantastic clip. It reminded me more of a custom light with this clip than a production light. It carries pretty deeply in the pocket too. I like the glossy finish here, it seems to almost take on a little color with oils from your hands. I carried this around the 4th of July holiday and found it to be nice and secure in shorts. 


Size & Weight

I measured the length at 111.34mm in length, 25.96mm at the head, and 23.39mm at the body. Weight with the Acebeam battery and clip installed came in at 124.8g or 4.4oz. It’s impact resistant to 1M and water-rated to IP68 (2 Meters). Here are a few photos of similar sized or spec’d lights that I have in my collection. 


LED & Beam

As mentioned the E70 Mini is using the latest LED from Nichia the 519a. This LED has quickly gained a cult-like following over on /r/flashlight and on the BLF forums because of its great neutral tint, that leans to the rosy side of things and high CRI. With my Opple meter, I measured 4973k and 97 CRI. The DUV of the light is very neutral as you can see. It’s the most neural emitter I have seen in a production light this year for sure. No PWM was observed either.

The TIR optic here produces a large even hotspot with basically no spill. It’s in that middle ground between thrower and flood, good for EDC type users, and the optic does a good job of diffusing that there are 3 LEDs here. I will be interested to see if people dedoam the light as that show make it throw a bit more, and rosy up the tint. I measured the parasitic draw at 72.1µA.



I measured outputs in my Texas Ace PVC Lumen tube and came a bit short in most of the categories, but everything was within 80% of the claimed lumens after 30 seconds.


Heat & Runtime

I tested my runtimes with the optional 3100mAh Acebeam battery. Turbo was good for right at a minute before stepping down to around 500 lumens. The heat peaked at 57C (135F) at the 1:15 minute mark, so this is mostly a thermal-based step-down. You can trigger turbo manually again and I did this during filming some night shots a few times and the light did get hot enough where it was too hot to hold. Running from turbo after the initial step down is pretty flat for 1:45:00 then gradual step downs for another 45 minutes till it shuts off.  

I did runtime measurements for Turbo, High, Mide 2 and Mid1 as well and plotted them all on one graph here. Turbo and High give the same total runtime which was a little bit of a surprise. Mid 2 was good for 3:51:00, and Mid1 shut off just shy of 8 hours. 



The UI here is as far as I can tell the same as what was in the full-size E70. It’s a little different from other lights but easy enough to understand once you know you have to double press to turn on and it’s this element that builds safety into not turning on accidentally. 


To turn the light on you can double press the tail switch to turn the light on in low, the light does have a memory so if it’s recent it will turn on in the last mode used excluding turbo. Once on, long press and hold to advance into the 4 available modes. Double press to turbo, triple to strobe. The light also has moonlight mode which you can access from off by long pressing, as well as lockout. Lastly, to turn off it’s a simple quick press to turn off.



The Acebeam E70 Mini doesn’t have onboard USB charging. Instead, it has an optional Acebeam battery with onboard USB-C charging on its side. I had no issues charging via USB-C PD, or C to C cables on a variety of chargers. The battery is a 3100mAh button-top protected cell that I measured at 3049mAh in my Vapcell S4 Plus charger. 

I measured LVP of the cell at 2.931V and charged the battery to full at 4.131V in 3:02:00. Charging curve looked good and the battery charged at an average of around 1A, definitely on the conservative side. The battery does seem to have a powerbank feature, that I can charge my Samsung Galaxy S22 Ultra with. With a meter and load, I was able to pull 2A without a problem. 


Final Thoughts

I had a positive review of the Acebeam E70, mine was in brass and has the High CRI LED, but it was too big and heavy for a front pocket EDC for me. The E70 Mini solves that problem, with the smaller size it still fits nicely into my hands, but the smaller diameter and lighter weight make it much more carryable. It’s still not a small 18650 light with its dual-wall construction but it’s a lot more doable. 

The best part for me might be the LEDs and beam pattern. The Nichia 519a LEDs live up to the hype for me. I have done LED Swaps on one of my Reylight LANs and a Reylight Pineapple Mini in Timascus where I dedomed it too and the result is just a pretty much perfect tint in my opinion. If you are a tint snob it’s a fantastic LED. It’s not the brightest LED available but it produces one of the best quality light/tints in my opinion right now. The TIR optic makes for a very usable beam too.

It’s not perfect, the UI here with the long press to turn on takes getting used to but it’s really only that small change. It’s not ideal in my opinion but it does provide extra protection so that it won’t come on accidentally in your pocket. It also doesn’t accept flat top unprotected batteries which I happen to have a fair number of. I do wish turbo lasted a bit longer before stepping down on its own too without retriggering, and the markings on the light don’t line up with the clip on my light. I do really like how they put some markings inside the battery tube to hide them.

This is probably going to be my new pick for someone wanting to spend between $50-100 on a 18650 sized flashlight with a tail eswitch, especially if LED and Tint is important to them. While there are cheaper ways to try a Nichia 519a LED this would be a great way to get into one with a great light around it.
