There’s a new US based seller of FireFly lights – FireFlyLite.US. This is a big change, since they’ll be handling warranty work too. Along with this change comes a change in name of the FireFly brand – it’s now FireFlyLite. They set an E01, and based on some news I’ve handled over at PhotonPhreaks.com, they have some very interesting lights upcoming! Read on for a review of the E01 they sent to me.
Official Specs and Features
There’s really just one version of the E01 but it’s available in two different finishes. There’s Matte Black, and “Silver” (seen here). “Silver” is really clear anodized aluminum.
These are selling for $49.99 right now at BraynGear.com (affiliate link). (That includes a 21700 cell and charger, too!!) The price gets you into the free shipping tier. And it ships from the US, so there’s no long wait!
I really liked the FireFlyLite E07, and this one is similar enough to be enjoyable in the same way. They’re very different lights though and compliment each other well. This is a good mix of “EDC” and “throw” and I have to tell you, I love the clear anno finish. Love it.

Package and Manual
There’s a manual included in the form of this:
It’s a nice little laminated card, with English (as seen above) on one side, and Chinese on the other. I guess this was my first time seeing the Chinese version of the Andúril diagram.
Build Quality and Disassembly
Alright, you probably didn’t buy this light without having experienced clear anodized aluminum before…. So you already know that it’s awesome. I love it. Not only does it have a great feel in-hand, but the threads on these lights are so smooth.
I don’t know it for certain, but I think this bezel is aluminum. I wouldn’t have been surprised to see a stainless bezel on here, but it looks and feels aluminum.
There is minimal branding, and even that branding is fairly faint. It feels laser etched.
The switch has backlight function, too!
What you see below isn’t so much “knurling” as just a milled pattern on the body. It’s adequate for added grip, and well finished.
The tailcap also provides adequate grip for removal. Again, these threads are so smooth that it wouldn’t really matter if the tailcap was blank.
The head has some grooves that to me look remarkably like tritium slots. These would be long slots, and what an interesting addition to the light!
The head has big and deep cooling fins. Also note that these cooling fins don’t have sharp corners. They’re beveled just a touch, which means they won’t hurt to grab.
This little bit among the cooling fins is the lanyard hole. More on that later.
The threads on the tail end are anodized (clear!), square, smooth, and a bit long.
The tailcap has a nice big beefy spring.
The cell tube is completely removable, but is not reversible. This does mean that the clip, which fits on the tail end, fits only on the tail end. The ends of this cell tube are threaded differently – you won’t install it improperly.
The head end also has a nice beefy spring, which has the spring bypass mod already done. I’m no flasher, but I’m fairly sure those 7 little dots on the head end at the 7 o’clock position are exposed programming pads, too. So if you wish to reprogram the E01, you can do so without any disassembly at all!
Here’s the other bit of laser etch branding. It includes a serial number!
Size and Comps
Size: 120mm (L)x 34mm(Head) x 26mm(Body)
Net Weight: 96 gram
If a light will headstand, I’ll show it here (usually the third photo). If a light will tailstand, I’ll show that here, too (usually the fourth photo).
Here’s the test light with the venerable Convoy S2+. Mine’s a custom “baked” edition Nichia 219b triple. A very nice 18650 light.
And here’s the light beside my custom engraved TorchLAB BOSS 35, an 18350 light. I reviewed the aluminum version of that light in both 35 and 70 format.
Finally, here’s the E07 beside the E01.
Retention and Carry
Included, but not installed by default, is a pocket clip. It’s a friction clip, and only fits on the tail end of the light – bezel down carry. It’s not a deep carry clip, but proportionally not a bad placement.
The clip has a couple of places for a lanyard to attach. First in the side of the clip.
And secondly, in the tip of the clip.
There’s another place for a lanyard to attach, too:
Right there amongst the cooling fins is a tiny hole suitable for a lanyard. Reminder: a lanyard is not included.
Power and Runtime
The E01 is powered by a single 21700 cell. Any type will work: flat or button, protected or unprotected. But the cell needs to be of the shorter variety – there are some button top 21700s that won’t make contact right. The right type cell is included anyway, so it’s not something you’ll need to worry about. Included is a 10A 4800mAh 21700 (similar to the Samsung 48G) (not what is pictured below!)
Don’t use an extremely high discharge capable cell in this light! There’s just one emitter and you can damage this emitter with too much current! (“Too much” is probably anything over 10A or so.)
FireFlyLite also includes a 21700 to 18650 adapter. There’s a little brass button in there, too.
Here are a couple of runtimes: Turbo and High. Turbo is the “double click from on” Turbo (which is the full FET output). And “High” is the “highest mode in the stepped group.”
This isn’t a charger review, but I went ahead and logged the charging done by this XTAR MC1S, which is included. It’s a simple single bay charger, and works adequately.
Modes and Currents
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps|
The first mode (at left) is the lowest of the ramping UI section. The rest are the stepped modes (in order low to high). You can also note from this, that the lowest mode of the ramping UI is lower than the lowest stepped option.
For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. And here’s the worst PWM light I have ever owned. Also one of the very first lights I ordered directly from China!
User Interface and Operation
There’s one switch on the E01. It’s a side e-switch, with four purple indicating LEDs. It’s quiet, but very clicky, and the rubber cover is nice and grippy.
This light ships with Andúril by ToyKeeper. Andúril is a fantastic UI, and extremely versatile!
In the photo below, the switch emitters (4) are actually lit.
And here’s a night shot of the same.
First off, here’s the UI chart made by ToyKeeper.

LED and Beam
The FireFlyLite E01 Luminus flashlight utilizes one main emitter in the E01. (In fact you could have guessed the “01” refers to one emitter, just like in the E07, the “07” refers to 7 emitters.) This emitter in the E01 is a Luminus SST-40 in “NW” but specifically 5700K. That emitter is under a TIR.
These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
Test light is on the left!
I compare everything to the KillzoneFlashlights.com 219b BLF-348, because it’s inexpensive and has the best tint!
What I like
- Good performance
- The clear anodizing is great!
- Tritium slots tucked away on the head?
- Andúril user interface
What I don’t like
- I don’t really need a crenelated bezel on this light
- The 5700K temperature comes with a bit of green.
- This light was provided by BraynGear.com for review. I was not paid to write this review.
