Acebeam E70 Brass Review (95+ CRI, GT-FC40 LED, 21700)

Today I am taking a look at the Acebeam E70 in Brass. This is one of the many variants of the Acebeam E70 that have been made, in many different materials, a few colors, and with LED choices. The one I have here has a new special high CRI large format LED which I will talk about here later on in the review. Acebeam sent this one to me as a gift, but I decided I would do a review for you guys too as this one is pretty cool I think.

Packaging and Accessories

A few notes on the versions of this light, you can go for a black anodized aluminum version, as well as Copper, Stainless Steel, a bead blasted or rainbow titanium and a polished brass which I have here. 

The packaging is a nice cardboard white box, with clear plastic window showing the light itself. In the case of the brass light it came sealed in a vacuum sealed bag, which I opened before I took pictures (a cardinal sin of flashlight reviewing). Acebeam sells this light with and without a battery, but everything else is included. A lanyard, manual, warranty card, and warning card, a Lanyard, extra orings, a felt drawstring bag, and a USB cable allowing you to use to charge the optional battery and use it as a powerbank.



Instead of covering everything on the design here I want to hit the highlights while you look at all the photos I have taken of the light. So somethings to note, the tail is flat so it tail stands well, on my version the electronic button in the rear is brass but this is normally stainless steel on the aluminum version.

The light uses a dual tube design, and they have chosen to mill out areas of the body tube to see the inner anodized aluminum blue tube. This creates a pretty unique look for a production light. It’s also a dirt trap, so probably not the light I would choose to go camping with but fun none the less. The body tube also has a place for 6 small tritium tubes milled, which isn’t seen commonly on production lights.

Threads are square cut and work well, although I had minor issues starting them on this light repeatedly. The head itself has holes drilled for style mainly and I like this look. The bezel is does unscrew and is quite sharp around the outer edges. The lens is mineral glass and the reflector has an orange peel. The internal connection points such as the springs are gold plated. 


Size & Weight

The E70 is a medium sized 21700 light, with length coming in at a measured 128mm in length, 30.2mm in diameter at the head. Weight with the battery was quite heavy on this brass model at 284.8g or 10.04oz. 



The light features a standard clip design with 2 screws, so your popular aftermarket clips will fit here. Kind of unique are the 3 predrilled locations for the clip. The stock clip is good but a little thin in my opinion for this lights weight. The front bezel is also pretty sharp, so I would personally think twice about EDCing this one inside a pants pocket, but it works great in a bag instead. 

LED & Beam

There are 3 LED options available in most but not all of the E70 varients. The base models use a Cree XHP 70.2 LED in either 5000k or 6500k at 70 CRI. Optionally on many but not all of the models there is a new Getian GT-FC40 LED at 4500k producing 95 CRI which is what I have. This required a driver change as well as this LED runs off of 12V instead of the 6V for the Cree. You take a decrease in performance though with the High CRI option at 2800 lumens instead of the 4000 the XHP 70.2 produces. 

The beam is a hot round center with some tint shift a rosy corona out into the spill. At distances this is mostly a flood light with the orange peel reflector and the massive doamless LED. It’s more pleasant to use in my opinion then a mule style flood since it does have a bit of optic but it’s not a thrower. Quite nice for normal tasks. 


Heat and Runtimes

I did my runtime testing with the optional Acebeam branded 5000mAh battery. Output on the GT-FC40 LED in my light here is somewhere between 2500-3000 lumens in turbo, and step down came at 1 minute and seems timed. It then ran at 35% relative output for 90 minutes, stepping down a few more times for total output at a little over 2 hours. While this is producing a lot of light, it’s certainly not the most efficient LED or driver combination I have seen. It also produces a significant amount of heat, that builds over time with this light in a pretty linear fashion. You are going to want gloves or turn it down for sustained use, max heat was at 1:30:00 at a crazy 84.9C (185 F). 



The UI here took me a few times to get used to, but the more I use it, it’s become a good UI that builds in an element of safety. To turn the light on you can double press the tail switch to turn the light on in low, the light does have 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 moon light 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. This seems to be a change over previous versions of the E70.



Charging is not built into this light. Acebeam sells an optional 21700 battery for an additional cost that has a USB-C plug on it. Recharging this cell took  2:07:00 to charge. You can use standard cells inside the E70, but you need to use a longer cell, like something that’s protected or a tall button top. 



My conclusion on the Acebeam E70 is it’s a nice higher end model of production flashlight with a lot of nice features that have been well thought out. I love that Acebeam continues to offer LED tint choices, and on this model different versions of LED’s. For an application like this I will take the GT-FC40 LED every day over a XHP 70.2, especially when I can get a warmer tint and high CRI. 


The brass and copper versions of this light are quite heavy with a battery, so if you were planning to use this as an EDC I would get one of the lighter versions like Titanium or even the Aluminum which also happens to be the most economical. I like that they included a standard clip configuration here so if you want you can further customize the light. I wish they offered a smooth bezel in the box too, this would make EDC in a front pocket a more pleasant experience. That said this is a bigger light and not one you will probably find me EDCing in my pants pocket often as a result. I will use it often for going on walks, etc. 

I can recommend this one without reservations, especially with the GT-FC40 emitter, it’s got a wonderful tint in my opinion and produces enough lumens for most tasks. That said it does get quite hot, but this isn’t because of the LED choice itself.

Reylight Quad Dawn Maratac (21700, 4000 Lumens, Cree XPL-Hi, 5000k)

Today I have the new Reylight Quad Emitter Dawn flashlight by Maratac. It’s a CountyComm exclusive light producing 3200 lumens out of 4 Cree XPL-HI LED’s in 5000k and can be powered from a 21700 or 18650 battery. It’s got this really nice dimpled style texture on the body all done in this grey type 3 anodized body. Let’s take a deep dive on this light and show what it’s capable of.

Packaging and Accessories

The Reylight Maratac Quad Dawn packaging is very simple. It ships in an orange hard plastic case with foam inside, some extra orings, and a plastic spacer for running an 18650 if you want to. The case is nice to store the light in but great to put other stuff in too. CountyComm is shipping these with a Samsung 40T 21700 battery but no charger. No manual is included but it’s a pretty simple 4 mode interface so you don’t need one. 



The light is made from 6061 aluminum and type 3 hard anodized in a gray matt finish. Starting at the tail switch, it’s a recessed textured rubber boot with a mechanical switch underneath. It has a satisfying feel and sound too it. The clip attaches at the edge of the light, using 2 purple anodized titanium screws and a titanium clip. I will talk more about the clip in the retention section. The only branding is opposite the clip, and it has the Maratac logo and the serial of the light. This minimal branding is great! 


The body and tail are a one piece design. I really like the almost golf ball like dimpling on the body of the light. CC says this increases the gripping surface by upto 300% over standard knurling, I don’t know how they come up with this calculation but I just like the feel in my hand and different look to most other lights on the market, and it won’t tear up your pocket insides. The head grows in diameter and has 4 tear drop shapes milled into it the length of the head. It’s a design feature that is common on many other ReyLight designs, like the LAN, and Gemini. 


At the front the bezel is raw aluminum to provide some contrast and when standing on the head it allows light to leak out letting you know if it’s on or not. The lens is sapphire, which is great for scratch resistance. Below that is the quad carillo style optic and LED’s. There is a green glow gasket underneath, it’s reasonably bright but definitely not turbo glow. 




Size and Weight

I measured the light at an overall length of 121.78mm, a minimum diameter of 25.5mm on the body and a maximum diameter on the head at 28.2mm. Weight with my 21700 battery is 140.1g. With a 30Q and spacer the weight was 127.6g.

The light is narrow for a 21700 and quad emitter light. Here are a few comparisons to similar quads or 21700 lights. 



For retention this light has the same pattern Reylight has used on the Dawn and Gemini flashlights. It’s a wide paddle clip that has the popular Steel Flame spacing for the screw holes, so you can upgrade to a skull clip if you like. The stock clip is 1.2mm Thick and quite stiff. It’s a bit of a challenge to get it to clip to my pants pockets. That said it’s very secure and isn’t going to go anywhere once clipped. I like how this light feels in my hand, it’s the perfect size for me and that dimpled texture gives a nice grip.

LED & Beam Shots

The Reylight Quad Dawn by Maratac is using Cree XPL-Hi LED’s in 5000k tint so it fits that classic neutral white tint, but to me it seems on the cool side of 5000k. My preferences in recent years has opted to the warmer emitters but this is nice too. The optic is all flood, and it’s pretty even with no real distortions, not something you see on all quads. The beam has a broad center with a slight corona, and the overall shape is slightly square at short ranges.

The middle 2 modes exhibit some PWM, It’s not bad and my eye or camera can’t see it but my scope can. See the example below. 



Heat and Runtime

The Reylight Quad Dawn by Maratac has quoted outputs of 2 lumens, 250 lumens, 1400 lumens and 3200 lumens. I did my runtime test with an Xtar High Drain (42A) 4200mAh 21700 battery because that’s what I had two of. I did a complete runtime in Turbo, which isn’t recommended because of the extreme heat, but it’s how I test all my lights in the brightest possible mode and see where they go from there. On this light it starts stepping down pretty soon after and a 0:2:25 it’s down to 50% relative output. From here it holds itself for an hour  before stepping down again and ending at around the 1:15:00 mark. During this time the light gets super hot, a whopping 78.9C (174F). This is dangerously hot, for both the battery and your skin. Again this isn’t recommended, CountyComm recommends only using “turbo” for 90 seconds and when you do that the light steps down much less and remains a warm but reasonable temp of less then 60C. I tested High only mode and fell a little short of the 2 hour quoted runtime but my battery is also 800mAh short of what the light ships with so I expect it to hit that without issue. 



The UI here is super simple, it’s a 4 mode flashlight, with moonlight, low, high and turbo. Mode spacing varies quite a bit, between 2, 250, 1400, and 3200 lumens. The mechanical button can accept half presses while on to advance the modes and then a full press to lock in on. There are no flashing modes on this light, which I am cool with. The light doesn’t have memory mode.



  • I love the golf ball style dimpled texture on the body, it’s different and functional. Nice grey anodizing here too.
  • Surprisingly light and small for a 21700 quad light.
  • No stepdowns due to thermals mean it stays bright for as long as possible but gets extremely hot.
  • Simple 4 mode interface, no strobe.



  • In continuous output in maximum output this gets super hot, Up to 78.4C in uncooled runtime tests. This is too hot to hold safely, so run the light only as bright as you need or can stand.
  • The pocket clip is super stiff, it takes effort to clip onto your pocket.
  • Some rattle with the 18650 adapter but that is to be expected.



The full name of the light (Reylight Quad Emitter Dawn Custom Maratac LED Flashlight + Glow Afterburner) is lunacy, but the quality of the light makes up for it. For a 21700 sized light it was smaller than I thought it would be. The slimness of the tube really helps.


It’s not something I will carry often in my front pockets for EDC for office tasks but you could carry it pretty easily in a larger pocket or back pocket if you wanted. It’s not too big in a front pocket either if you wanted. For me it fits great in the hand and that is only made better with the dimples for grip. It’s a great walking the dog type of light, high at 1400 lumens and the floody beam is more then you need, and with 2+ hours of runtime it is plenty for most people. One more mode between low at 250 lumens and high at 1400 lumens would make it a little more useful I think.

That said on Turbo for continuous use this light is dangerously hot, 78.9C (174F) is burn you hot, that said you I only saw this at the 31 minute mark and I don’t think you will see it in the real world because a sane person would shut the light off or turn it way down as you wouldn’t be able to hold it. I don’t recommend running your light in turbo for so long because it’s not good for the battery either. 

Overall this is a nice light at a fair price. I enjoy it and am glad I have one. It’s easy to recommend and is a nice size too.
