Review: BlackShadow Eva [AAA Flashlight]

BlackShadow Eva AAA Flashlight

As a collector of AAA flashlights, I'm always looking for something new. The BlackShadow Eva caught my eye because it's a simple design coupled with higher end fit and finish, which is something I'm not used to seeing. So, I bought one from llumination Supply. They are currently offering 25% off on all BlackShadow flashlights, and with their reasonable shipping rates, I got the Eva for only $17 shipped!

Product Description

Price: $20 online

The Eva is a single mode, twisty AAA flashlight. BlackShadow seems to be going for the simple and elegant vibe with this one. Single mode lights like this one are nice because it's not possible to be confused when operating it. Twist to get light, twist the other way to turn the light off. It's stupid simple.

Overall Design

BlackShadow Eva AAA Flashlight - Packaging Open
The Eva has a fairly elegant design. First off, it appears that this is just another pretty looking light with a slippery bezel which makes the light a pain to get enough grip on twist on/off. But the stainless steel ring is just part of the head. Right below it is a band of nice, grippy knurling. So, the light is easy to operate one you figure out that the knurling is part of the head. The stainless steel looks good but doesn't get in the way of operation. You get form and function.

The rest of the body of the light has several ridges on it for anti-roll purposes. It's only marginally effective to stop rolling, so I'm guessing it's as much for looks. The ridges also serve as a sort of counter-grip to twist the head.

The design claims that the light is capable of tail standing, but that's a stretch. It's only possible on a perfectly flat surface if you are very patient, which I am not.

The Eva uses a Cree XP-G R5 emitter, which is well suited to the AAA form factor of flashlights.
The R5s tend to have a cool white tint, which this sample has. The emitter uses a centering ring, which is normally found on larger, higher end lights.

The Eva has some interesting optics. The beam on mine looks a little lopsided even though the emitter is well centered.

The beam on the Eva has a fairly tight hotspot for this class of AAA light. Not as tight as the throwy Thrunite Ti or the Streamlight Microstream, but a little more throw than I would expect for this type of EDC light. 

Run Time Test

2 hours, 1 minute.

I did my own test running on a 2nd generation Eneloop straight off the charger. The light started to dim noticeably almost at the 1 hour mark exactly and hit sub-lumen output at about 1:20. At 1:50 I could barely see any light, and it finally konked out at 2:01. It's nice to see companies finally giving conservative run time estimates. And it's nice to see lights that will go "vampire" and squeeze out every little bit of juice from a battery.

The run time seems pretty typical of lights in this class running on high. I hope they make an XP-G2 version, which would kick up the run time even more.

Fit And Finish

BlackShadow Eva AAA Flashlight - Closeup of Threads
The Eva looked beautiful in the photos and it's just as nice in person. This thing looks like it belongs in a tuxedo pocket or something. There's no discernible flaws in the anodizing, scratches or tool marks. The lettering on my sample is crisp and the LED appears to be intentionally well centered as part of the reflector design.

The threads look good. They are typical triangular, anodized and lubricated like they should be. There does however appear to be a little bit of dirt on the threads from looking at the pictures.


The usability of this light really surprised me. I had forgotten how useful a single mode light could be for EDC. And with the solid grip twisting it on and off, this light has held its own day to day. The Eva also has an EDC friendly beam. It's a good combination between flood and throw, with a tighter hotspot than most of my other AAA flashlights.


This light has turned out to be a gem, and will probably be destined for keychain duty and definitely for when I'm wearing with a suit or need to dress up like an adult. I'm sure in the end I'll go back to a multi-mode light like the Olight I3S for EDC, but this is a really useful light, and the single mode would probably be better for most people.  I intend to give some of these away as gifts.

BlackShadow hasn't been around very long, but just weighing this light on its own merits, I think it's a winner. I normally prefer multi-mode lights, but I wouldn't change a thing about this one.

Review: Nitecore EA4 Pioneer [AA Flashlight]

Nitecore EA4 Pioneer 4xAA Flashlight - New In BoxIt was AA flashlights that helped make me a "flashaholic." But, like most flashaholics, I soon moved on to Lithium-ion flashlights, which pack more of a punch, though li-ion batteries can be dangerous if not handled with care. Multiple AA, high output lights have been around for a while, but the Nitecore's combination of features and its compactness intrigued me, so I bought one from Amazon.

They had it almost 15 bucks less than the nearest competitor, though the instructions were in German.

Product Description

Price: $55-$70 Online

The box says "compact searchlight" and that's the best description I can think of. The EA4 takes 4 AA batteries and has output comparable to a high end, Lithium-ion powered 18650 tactical flashlight. And due to its large, smooth reflector, probably out throws most of them.

Since my sample came with instructions only in German, I am linking the user manual in case anyone else needs it.

Official Specs

Here's the product link on Nitecore's web site.

    Nitecore EA4 Pioneer 4xAA Flashlight - Out of Box
  • Takes 4 common AA batteries
  • Cree XM-L U2 emitter
  • Includes spare o-ring, lanyard and nylon holster
  • Two state electronic switch (similar to a camera)
  • Switch lockout feature
  • Can tail stand
  • Uses deep, square cut threads
  • Blue beacon light in switch doubles as voltage meter

Overall Design

The predominant feature of the EA4's design is the two-stage, electronic switch on the side of the body, near the bezel. A slow half press on the switch gives you a momentary on lower mode, and a slow full press on the switch gives you momentary turbo mode. If you give the switch a full press or half press, the light stays on in those modes. Once the light is on, further half presses cycle between low-med1-med2-high and further full presses cycle between turbo and high. The hidden strobe is accessed by 3 quick full presses. I wasn't sure I liked this user interface, but the more I use it, the more I like it. At first it seemed clumsy, but now I can see that it's actually very well thought out.

The rest of the design is pretty much straight forward. You load the 4 AA batteries in the back, and use the side switch to access the flashlight. There's a lanyard hole in the tail, though this light seems a bit bulky for a lanyard. 

The cooling fins on the body also give the light a better grip. The only knurling is at the tail, where you unscrew the cap to access the battery compartment.


Nitecore EA4 Pioneer 4xAA Flashlight - Shown With EneloopsNitecore EA4 Pioneer 4xAA Flashlight - Shown With Tail Cap RemovedThe EA4 uses 4 standard Alkaline or Ni-MH rechargeable batteries. I am assuming that it will take lithium primaries. I'm normally brave when it comes to trying Li-ion batteries, but not even I am brave enough to try 4 14500's in it. 

The batteries get loaded straight into the battery compartment. There is no caddy to load them into like some lights in this class use. There are two pins to align the springs, and the entire circuit board in the tail rotates freely. Interesting but effective.

When batteries are loaded into the unit and the tail cap is screwed on, the blue indicator light will flash quickly giving you two sequences: the volts and the tenth of volts.


Nitecore EA4 Pioneer 4xAA Flashlight - Closeup of Threads
The threads on this light are square cut and deep, which is nice. They are also anodized. Overall they have a really good feel, and it's one of the things that gives this light a high end feel to it. The only knurling on the entire light is on the tail cap, which only adds to the good feel.


The large, smooth reflector gives the EA4 a nice, tight hotspot for an XM-L, though at the expense of the off-colored rings, also common to the XM-L. Normally I would trade a nice looking beam for a little throw, but in this case, I like it just the way it is. Don't mess with my throw, bro. There's just enough spill to be useful at close range, but again, that's not what this light is really intended for.

It's been reported that an Olight M21 diffuser will fit almost perfectly on the EA4. When I bought the EA4 it hadn't dawned on me what a great lantern it would make with the right diffuser, but after seeing pictures on CPF, I'm sold, and I intend to buy one.

Fit and Finish

Notice the uneven gap in between the bezel and body
The fit and finish on my sample is good. My sample has the tiny gap between the bezel and the body that some have reported, though it's easy to miss. I do not know if this is an intentional part of the design or a fit and finish issue. I don't believe that it makes the light any less waterproof. My only other gripe is that the threads were over-greased, but most companies don't put enough grease, so I'm happy to remove some of the excess.
Nitecore EA4 Pioneer 4xAA Flashlight - In Sheath
It has an above average quality nylon holster
Overall though, the fit and finish is more than acceptable. The threads are perfect and there's no scratches or flaws in the anodizing or tool/machine marks anywhere to be found. The emitter is well centered.

The ballistic nylon holster also has a good fit and finish. The stitching on the holster is above average for a holster in this class, and they make liberal use of velcro. This is one of the better holsters I've seen, on any light. The belt loop even has its own velcro to make it easier to get the holster on and off of your belt.


The high output, compact size and great throw make this light well suited for large, open, outdoor spaces like for camping or on the farm. The brightness levels are well spaced and well thought out. I have seen a few people complain on the forums that there's no low-low mode, which is true. I'm personally a big fan of the so-called moonlight modes, but I don't see the need for this light.

This is the kind of light that sits on your holster and allows you to see a couple hundred yards away in the forest. It's not well suited for a nightstand light, and the levels and spacing reflect that. Having said that, I wouldn't complain if there were a low-low hidden mode that was tucked out of the way like the strobe.

Though I'm still waiting for good camping weather, I have tested this unit extensively outside. Standing on my street, the light has so much output that the bounce-back from the road sign all the way at the end of the street is blinding. When I activated the strobe, a couple neighbors came outside to see what it was!


This flashlight is everything I hoped it would be, though the little gap in the bezel takes away from the high end fit and finish.

But all things considered, this light is worth every penny and more. I don't know how I got it for $55 shipped from Amazon, because they seem to have raised the price more inline with other vendors. But it's still a bargain at $70.

I look forward to using this light for camping when the weather gets a little warmer. I normally bring an 18650 size tactical light with me, but I intend to just bring the EA4 as my primary "is that a bear?" thrower. It's currently sitting on my desk next to my Maxpedition EDC pouch, which my wife calls the "man-purse."

Knife Steel Comparison App for Android And iOS

I have seen people on some of the EDC and knife forums mention a free knife comparison app. I had watched a youtube video showing the app, but I didn't realize it was available as an Android app as well. As suggested in the video, I did a search for "knife steel comparison" and this app came right up. Now I have it installed on both my Android phone and tablet, both of which are running Ice Cream Sandwich. I have no idea if it works on Gingerbread.

The company which created this app is zviSoft. Their web site is and their apps can be downloaded straight from the web site.They also have a blog on the site, but it appears mainly to just be release notes for the various service releases of their app. There doesn't appear to be a Windows version.

The app is easy to use. Just find the steel you want, and it will tell you everything you want to know. It's a great little app!

Searching for "S30V" gave me an info screen:

Then I clicked the settings button and chose the graph:
