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.

 

Construction

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. 

 

Retention

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). 

 

UI

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.

 

Recharging

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. 

 

Conclusion

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.

Wurkkos FC11 Review (Samsung LH351D 5000k 90 CRI, USB-C, 18650, $30) Discount Available

Wurkkos (Pronounced Workos) is a new brand on the market. They are being produced along with the assistance of Sofirn and sharing a factory. The Wurkkos FC11 caught my eye because it was using desirable Samsung LH351D high CRI emitter at 5000k, had USB-C and is pretty affordable. Thanks to Wurkkos for sending this to me to take a look at and review. Be sure to check the description of the video for a discount available to my viewers for this light.

Packaging & Accessories

Packaging is a yellow and white cardboard box with just the company name on the outside. Inside the light came wrapped in a bubble, and accessories include 2 extra orings, generic lanyard, and a USB-A to USB-C cable. The light comes with a non deep carry pocket clip on it and a Wurkkos branded 3000mAh 18650 battery inside. I tested the battery capacity at 2854mAh on my Xtar VC4S charger. I can read the battery code as 01VCEAJ?1224?18CF0000180. 

 

 

Construction

The Wurkkos FC11 is made from aluminum and hard anodized a semi gloss black. Very similar to Thrunite or Sofirn’s lights. The tail is flat, and magnetic, strong enough to hold the light horizontally. The knurling on the tail cap is straight but with some inpercise milled flats around it, It’s not noticeable unless your really looking. Threads are shallow square cut and anodized. 

 

The body tube is ribbed which I like the look of, it’s different, not a grippy design though. The clip only attaches on one end of the tube but the tube is reversible so you could mount it at the front if desired. I do hope Wurkkos releases a deep carry pocket clip for this light as it would improve it’s EDC ability in my opinion. There is a little battery body rattle when the light is shaken violently but it’s minimal, and dual springs in the tail would improve the noise you get if you strike the light, but it didn’t ever lose contact with the battery for me. 

The head is pretty standard looking, the semi transparent button has texture on top and sits fairly flat, it has a blue bezel that kind of reminds me of Olight but looks good. The sides around the pill area have a bit of a fin shape milled in and could use a little more deburring. The USB_C charging port is opposite the button and covered with a large silicone door that fits pretty well. The lens is plain mineral glass, the reflector has a basic orange peel and the Samsung LED is nicely centered. 

 

Size & Weight

I measured the FC11 at 116mm in length. 24mm at the tail, and 25mm at the thickets part of the head. Weight with the included battery and pocket clip was 112.1g. The light is IPX 7 rated (Water upto 1 meter).

Size wise there are a lot of similar lights to the FC11. Length and diameter wise the Convoy S2+ is basically identical but my S2+ is the UV model so not a great comparison for beam shots. My Thrunite TC15 is about 7mm longer and about 1.5mm larger in diameter. 

 

 

LED | Beam Shots  | Heat

The Wurkkos FC11 is using the Samsung LH351D LED, in 5000k and is also considered high CRI at 90. This is a great LED to use, and one of the light communities favorites right now because of it’s high CRI and neutral tint. It’s also my first time getting a hold of this LED and I am a fan. Mine seems to be pretty neutral with just the slightest tint of green but I have heard of others getting a more green tinted LED. That’s how the bin lottery works unfortunately. The light uses an orange peel reflector behind a non AR glass. The beam profile here is does have a bit of a hot center, but fades nicely into spill. No undesirable rings or artifacts in the beam itself. Good for general use.

Runtime & Outputs

For my runtime graphs here I used the included Wurkkos 3000mAh battery and made sure it was fully charged each time. The driver is non regulated FET, and features a timed step down, after that output is linear to the cells voltage. I didn’t notice any slow PWM in the lower modes for this light and have equipment coming here soon so I can measure this on future lights. When it arrives I plan to update my blog post so make sure to check that out.

Turbo is listed at 1300 lumens and started to step down at about 75 seconds and was fully decreased to right about 25% relative output by 90 seconds. From here the light was a very linear decrease out to 425 minutes of runtime where LVP kicked in at 2.825V. I ran this test both from turbo and just high and got very similar outputs. You don’t see that many modern lights that have output graphs that look like this. It’s a cost cutting measure. Personally I would pay a few more dollars to have a regulated driver.

Heat was well controlled during my runtime tests. At 1 minute I measured 85F, at 5 minutes I measured 87F, and at 10 Min I masured 90F. This is actually pretty cool for a modern light.

 

Official outputs are listed as following.

  • Turbo 1300 Lumens
  • High 700 Lumens
  • Mid 300 Lumens
  • Low 50 Lumens
  • Eco 2 Lumens.

UI

The Wurkkos FC11 has 2 UI options for people to choose, a stepped (Default) or a ramping. To change UI while off, hold the button for 3 seconds and the light will flash twice to let you know it’s switched.

 

The light ships by default in stepped mode, and it’s fairly straight forward. From off, tap to turn on, and tap again to advance in mode. You have eco, low, mid and high as part of the normal modes of operation. To turn off Long press when on. Double click to go to turbo, Triple click to go to Strobe, and 4 clicks to enter and exit lockout. The light also has memory mode for the single click modes. This is all pretty standard but at first I found myself clicking and holding to advance modes as many other lights do but this light doesn’t.

 

Ramping mode Is fairly straightforward, the light starts low and ramps up quickly to it’s highest output in about 1.2 seconds, and flashes to let you know it’s at the top. If you release and then press and hold the light will decrease in output in the same amount of time flashing to let you know it’s at the bottom. You can stop at any output and then click again to reverse the direction you were going mid mode. The same shortcuts of double clicking to go to turbo, triple click to go to strobe, and 4 clicks to enter and exit lockout work here too. There is no hold from off to get to low mode like you see on some lights when in ramping. Not a deal killer for me. 

 

Recharging

Recharging here is accomplished via USB-C on the light itself. Unfortunately this requires a USB-A to C cable and USB-C to C is unsupported.  Charging of the 3000mAh battery was very linear during the 4 hour and 37 minutes it took to go from LVP at 2.825V to full at 4.13V. It almost immediately went to charge at 1A and then declined slowly and linearly creating a very linear but not the most ideal curve for a lithium battery. The lights electronic switch flashes fairly bright red while charging and then goes solid green when charged. The light will operate in low mode during charging. 

 

Pro’s

  • USB-C charging but not USB-C to C.
  • Samsung LH351D Neutral white high CRI Emitter
  • Very affordable price for a complete package
  • Magnetic Tail 
  • 2 UI options to choose from, stepped or Ramping

 

Con’s

  • I would prefer a deeper carry pocket clip option, if so this would make a decent EDC option. 
  • Some people have reported a bit of tint lottery with the LED. 
  • Non regulated drive, After initial step down the output is lower and linear based on voltage.
  • Dual springs would reduce the small amount of battery movement noise. 

 

Conclusion

I will be honest, when I first saw that Wurkkos was offering me this light, I didn’t know who they were and didn’t think much of it initially, but I am glad that I looked closer and ultimately said yes to get my hands on it. For $30 at time of filming, a neutral tint, high CRI (90 CRI) emitter, onboard USB-C charging and an included 3000mAh battery, I am impressed. This would make a great gift light to give to someone as a first real flashlight or a good way to experience the Samsung LH351D LED if you haven’t already. While the ribbing on the body isn’t revolutionary it’s nice they decided to do something different to make them stand out a little bit from the other knurled lights on the market.

 

This is going to be my budget 18650 recommendation for people new to the hobby or want a beater light until I run across something better. This is a high value combination, good emitter, 2 solid UI choices and a complete package deal. It’s not perfect but the positives outweigh the negatives. Maybe we will see a slight revised model next year like we have seen from the likes of the WowTac A1 to A1S and they will fix a few of these minor things and stick in a regulated driver. Overall I recommend the Wurkkos FC11 and look forward to see what they do next.

 

Wurkkos has provided a discount till the end of the month to my viewers that I have in the description below this video, so if I have piqued your interest in this nice value flashlight be sure to check that out and save a few dollars while your at it.

Folomov C2 Review (400 lumens, 98CRI, Super small, 14300 battery, Summer EDC)

The Folomov C2, is a very small EDC light with a very high CRI (98CRI) warm beam, magnetic tail cap, and USB rechargeable battery. It might be a just about perfect little summer EDC. Thanks to Folomov (Affiliate Link) for sending it to me to take a closer look at and show to you guys.

Just a reminder to everyone to make sure you join my Facebook page for the YouTube channel and my reviews, where I try to post a few days a week, new arrivals etc, and take a look at the Patreon page I have setup for the channel as well.

Youtube Version of this Review: 

Packaging

Instead of a box, the C2 comes in a small tin with foam inserts. The top cover is laser engraved with the name and brand. It would make a nice gift box. Included with the light is a pocket clip, battery, extra orings, manual and micro USB charging cable.

Construction

The light is made from aluminum and hard anodized a satin black. Starting at the tail it’s magnetic, and flat, so it tails stands well. The tail cap sides have just a little milling in them to add style and a slight amount of grip. Inside threads are anodized and square cut. The body is tiny at only 19mm in diameter, It has 2 flats where the minimal labeling for the light is (Just the brand and model name).

The button and clip segment grow in diameter slightly, similar to the Olight Mini series of lights. Folomov choose a gray button that has 2 LED’s underneath to give a bit of a charge indication. They are green when the battery is charged and turn red when the battery is low. The head section has small teardrop areas milled in. The bezel is a polished aluminum. The glass lens sits recessed a little and underneath is a orange peel reflector.

The clip is fixed in a tip up position and fixed rotation, this allows you to mount the light on the bill of a hat if you wish to do so. The bad part about this clip is the bend at the top is just too tight, there is only about 1.5mm of space at the top of it, so it’s difficult to fit over the brim of most hats, and even pants or shorts pockets are usually thicker than that at the seam. The result is it just doesn’t carry as deep as it could, but it still carries better then many lights.

Size and Weight/Comparisons

This is a seriously small light, I measured length at 55mm, max diameter near the switch at 19mm, minimum at 16mm. Weight only comes in at 31.7 grams with the battery and clip. The light is IPX8 Water rated as well.

The C2 does share a lot of design features with the Olight SMini series of lights, but is about 20-30% smaller. It’s not a revolutionary design but one that works well. For me the C2 has proven to be a great summer carry, as I am wearing shorts more, I want smaller and lighter weight things in my pockets and the C2 fills that gap while still having quite a bit of power. The magnetic tail cap just add to it’s utility. It does only have tip up carry which some people will love, others will hate.

LED/Beamshots/Runtime

The little Folomov C2 is using a Nichia 21A LED. The tint is 3000k and an exciting 98 CRI. The beam has a hot center that covers about 30% of the beam and then a minimal amount of light in the spill. I like warm high CRI beams, I will admit the warmer tints can take some time getting used to especially if you have a lot of cool white low CRI lights now. For me I always will take high CRI if I can get it as I just prefer colors to look natural and it’s good for any photography too.

Folomov rates the light at a maximum of 400 lumens in turbo, 160 lumen in high, 50 lumen on medium, 10 lumen on low, and ½ lumen on moonlight. It also has strobe, SOS and bacon all at 160 lumens.

Runtime is nothing outstanding, due to the 14300 sized battery at 250mAh. It’s just a really small battery in terms of capacity, part of this is to fit the microUSB charging circuit on which barely fits. So in my runtime tests the light was on for 65 minutes. Turbo is really only good for about a minute, before stepping down pretty significantly. The next 30 minutes you get a usable amount of light. The last 30 minutes is just above moon light mode modestly.

Low voltage protection kicked in at 3.08V. The light does have reverse polarity protection and some thermal protection. Parasitic Drain was measured at 2.0uA.

 

UI

The UI is straightforward and logical in illumination mode.  Low, Medium, High, and then it repeats. Direct access to low is available by long pressing from off, and a double click takes you to turbo. Low, Medium and high are available for memory as well. There is lockout mode which you can activate by pressing the button 3 times quickly, and you do the same to unlock. This mode is very similar to Olight’s UI, so if you know it you will catch on quick.

There is a tactical mode which I think is a little silly on a light this small but it does have it. To go between the two you click the light 7 times from off. It makes the side switch a momentary turbo if pressed and held. If the button is pressed quickly it locks turbo on,and if you double click the side switch you get strobe.

The light ships in the default mode which is where I think most people will want to leave it.

 

Recharging and the Battery

Recharging the 14300 battery is easily accomplished with the MicroUSB port on it’s side. The USB charging circuit sits on top of the battery and has red/green LED to indicate charge status. Full Battery Voltage was measured at 4.207V. Total recharging time took just 1 hour and the maximum charging speed I saw was 0.3A which is appropriate for a cell of this size.

I suspect the battery being used here is really more like a 14200 sized sell with the last 10mm, being the USB recharging circuit. You can see the line in the battery. 14200s are also much more available then 14300s, that said I am not finding any 14200’s that match the capacity here. While I understand why they went with USB recharging especially for such a small cell, it does hurt capacity as it takes up valuable space.

 

Pro

  • Warm White high CRI. 98CRI is just fantastic on an EDC this size.
  • Small size, this was smaller than expected and carries really nice
  • Easy to use UI that’s what you would expect

Cons

  • The pocket clip is narrow, meaning anything but very thing pockets won’t ride all the way down in the clip.
  • Not a common battery size, Folomov says they will at some point have additional batteries for purchase.
  • Low capacity battery at only 250mAh.

 

Conclusion

For me the Folomov C2 is a hit. It’s enough light to get me through an office or light duty EDC use, but has enough power to do a few other small tasks. For any larger tasks I would want a larger light nearby in my home, car, or office. It’s not a light I would go camping with or use for extended times due to the small battery but it’s more useful than most keychain lights without being too big in a pocket. I love the high CRI warm LED, this is what sets it apart from the competition that typically prefers cool white LEDs. My only main concern is the availability and cost of replacement batteries. Folomov has said they will be available but hasn’t said when or at what cost.  Overall it’s a nice light, with a straight forward UI for a pretty affordable price. I recommend it for a very small light weight EDC.
