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.

 

Retention

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.

 

Outputs

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. 

 

UI

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.

 

Recharging

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.

Thrunite BSS W1 Review (693 Lumens, SST20, 16340 Battery, Onboard charging)

Thrunite has a new light in their BSS (Black Scout Survival) series of lights this time focused on the compact small EDC market. This light produces 693 lumens from an SST20 LED and a 16340 battery. It has a deep carry pocket clip, and is available in two different colored bodies. It’s very similar to the Wowtac W1 I looked at earlier in the year with a few differences. Thanks to Thrunite for sending this too me to look at, if I have a discount for it make sure to check the description below.

Packaging & Accessories

Packaging here is a rather small cardboard box that folds up from the top. On the side it lists the option the light is in, interestingly a black version and NW is optional here but those options are not listed for sale currently. Inside you get the light itself, along with a 16340 battery. Mine here happens to say it’s a Wowtac (Sister company) so maybe they had some wrappers leftover? Other accessories include the pocket clip, microUSB to USB cable for charging, manual and a bag of 2 spare orings, 2 spare USB covers. 

 

Construction

The W1 is made from aluminum and at current time is available in an OD Green and a Blue. I like the green color here myself quite a bit. The back end is mostly flat, it has a small milled center thats slightly lower with the Black Scout Survival logo engraved in the center. On mine the logo doesn’t really seem to be lined up at all with the head. The tail is magnetic and pretty strong, it has no trouble holding the weight of the light up. 

The pocket clip attaches at the rear of the light only, it’s a non captured clip and the tail and body are a one piece design. The groves milled into the body section are nice, they give quite a bit of grip but should clean up much better than traditional diamond knurling. The body also tapers in, to give the light the feeling of thinness

The head section of the light is a decent amount larger than the body, especially around the button and USB port area. This does change how the clip fits the light, more on that in a minute. This larger section serves as kind of an anti roll ring. The button is slightly recessed and protected with the aluminum around it. There is a LED underneath to give a charging status. Opposite the button is the charging port. It’s covered with a silicone cover. Not the best design I have seen but effective for the price. The front has a very shallow bezel that’s smooth. It looks to be a 2 piece design but I can’t get it to budge. The lens is anti reflective coated and the reflector does have an orange peel. The LED centering isn’t perfect but this doesn’t seem to have a noticeable effect on the beam.

 

Size & Weight

I measured the length here at 67mm, maximum diameter at 23.22mm at the head, and minimum diameter at the body at 18mm. Weight with the battery and clip was 51.5g. The light is IPX8 water rated.

 

The Competition

The closest light I have to the Thrunite BSS W1 is the Wowtac W1. As you may or may not know Thrunite and Wowtac are sister companies, and these two lights are very similar in terms of physical appearance, design, and shared parts. There are some differences, most obvious is the body tube differences. The Thrunite BSS W1, has in my opinion a more attractive body tube, with its linear milling, it’s also a little slimmer by 2mm. The heads are the exact same design with the only difference being color, and accents. They have the same button, USB Cover, bezel, lens, and reflector. The heads are also interchangeable between lights. 

 

The Olight S1R Baton II and S1 Baton Mini are both smaller then the Thrunite BSS W1, in terms of length, and as far as the mini has very similar maximum performance. One big difference is that the Olights carry bezel up, and the Thrunite is bezel down carry.  

 

Retention

The Thrunite BSS W1 uses a non captured dual direction clip that only fits on the tail of the light. It’s a pretty tight clip, enough so that it does scratch the anodizing, it’s very deep carry which is great and has enough space to fit over the pocket of my jeans to clip onto the pocket. The light also has a small place in the tail to allow a small diameter lanyard to be attached if you wish.

 

LED & Runtime

The Thrunite BSS W1 uses a SST20 LED in Cool White. No tint data is given directly. When I compare the beam to the Wowtac W1 it’s very similar, the SST20 in the Thrunite is slightly more neutral in tint to the Cree G2 in the Wowtac. The beam hot spot is slightly large as well. On this style of light I personally prefer a TIR style optic, because I think it provides a better overall beam for EDC use, that said the traditional reflector design here does throw further. 

 

Thrunite lists the output specs of the BSS W1 as the following.

  • Firefly 0.5 Lumens
  • Low  7.5 Lumens
  • Medium 58 Lumens
  • High 215 Lumens 
  • Turbo 693 Lumens with step down to 215 lumens after 1 min.

 

Heat & Runtime

Turbo runtime on the BSS W1 was 1:15 before step down, relatively short but this is a small light. Past here it seems to follow the curve of a non regulated driver. It ran at 30% relative output for right at an hour before slowly stepping down. Total runtime was 1:43:00 before the light shut off with the battery measuring 2.925v.

 

UI

UI here is extremely simple. From off, long press to enter firefly mode at 0.5 lumens. Once on long press to cycle through the 3 normal modes. Double press to go to turbo, or triple press to go to strobe. There is memory mode here. No lockout mode is here but you can mechanically lock the light out if you wish by a ¼ twist. 

 


Recharging

Recharging is accomplished via MicroUSB onboard the light. The charging port has a small silicone gasket that’s hinged at the top at one point. It’s not the best design I have seen, not the worst either. Charge time took 1:21:00 in my testing, with the max charge rate being .46A which is safe for this small of battery. The fully charged battery measured 4.145V. 

 

Pro’s 

  • Very inexpensive (Less than $30)
  • Only a cool white emitter available at this time.
  • Blue and Green anodizing are available.

 

Con’s

  • Not a crazy amount of performance but it is small.
  • MicroUSB instead of USB-C
  • Bit of a green tint on lower power modes.

 

Conclusion

If you are new to EDCing a flashlight, and wanted to try something small out, this would be a great option to try without breaking the bank. If you just wanted a small flashlight to use on a hat, carry in a bag or purse, or just wanted an impulse buy in a color you liked this fits all those applications here too. 

 

For EDC this is a decent light. The clip design allows for a pretty deep carry which I like, but the head design means I need to pull it out slightly to slip the clip over the side of my pocket. I like that it’s available right away in colors, and that they didn’t wait for a special edition with colors later on. It’s a little disappointing to see that it didn’t go to USB-C for the onboard recharging. 

 

The Thrunite BSS W1 is very similar to the Wowtac W1 that I reviewed last year. The exterior designs are slightly different, and I prefer the Thrunite BSS W1 here. I like the two anodizing colors being offered here an OD green and a nice blue. The SST20 LED is a little brighter than the Cree emitter used in the Wowtac W1. For the minor price difference (Around $25 total price) here between the two models and the availability of body colors, I would say to  buy the Thrunite BSS W1 over the Wowtac W1 at this time but I can’t say you would be wrong choosing either.
