Here’s the second of a few lights I received from Neal’s Gadgets. I’m happy to be reviewing these FireFlies lights. This is the E07, a 7 emitter light, with a few emitter options. And Anduril firmware! Read on to see how it performs.
Official Specs and Features
There are many versions of this light! Let’s start with the body colors. There’s Gun Grey, Clear-Anodize Aluminum Alloy, Matte Black, and a color which doesn’t seem to be listed at the FireFlies site, which is what I have here: champagne (called “yellow” at Neal’s).
Then there are emitter options, which are as follows:
XPL Hi V3 3A 5000K Neutral White (+$20.00)
XPL Hi V3 1A Cool White (+$20.00)
XPL Hi V2 5A 4000K Neutral White (+$20.00)
SST20 10W 5000K NW
SST20 10W NW 4000K CRI95
Neal’s Gadgets even has some special models:
7x Nichia 219B R9080 CRI98 3500lm (my review sample)
7x SST20 6500K CW CRI66 4500lm
Then there’s the color of the Auxiliary LEDS: Blue, Purple, Yellow, or Red
So there are a ton of options. Plenty of opportunity to get a setup you like.
Price and Coupon
Here’s a tracking link to Neal’s store. These start at $55, and go up to around $80, depending on the configuration you choose.
Neal gave me a 10% off coupon for this light, too! The code is NDFFE07.
This is definitely a fun little light. I like that it uses 21700 cells (with the option to use 18650 cells with the included adapter). I love 219b emitters, too! I think this is a nice light for the price, and I recommend it. I’d pick the cell you use carefully, though – don’t get a cell that would overpower the emitters you choose!

Package and Manual
Fireflies has a special embossed box, with foam inside holding the parts in place.
The end of the box has a sticker that includes the details of the light you’ve ordered. Model name and emitters, in specific.
Here’s the manual:
Fairly simple, but the bases are covered.
Build Quality and Disassembly
The feel of the anodizing is the first thing you’ll notice when holding this light. It’s a very matte finish. Not quite Armytek, but just enough so that the texture could be considered part of the grip. Based on the photos of the other models (particularly the clear aluminum version) I think the others may not be quite as matte as this Champagne.
The center also has some grip pattern.
The tailcap threads are anodized and square cut, and quite long (lots of twisting).
The threads on the head end of the cell tube are even longer, and also threaded finer, so the cell tube is not reversible.
Below, note the head and tailcap springs. Both thick and beefy, and the spring on the head end has already been bypassed for better current flow!
The bezel unscrews easily, and the optic comes right out. There’s a lens under the bezel over the optic (pictured, but probably impossible to see, below).
I have included a bunch of shots of this driver, because it’s incredible. I love looking at it.
The mcpcb actually consists of two boards. One houses the main emitters, and the other is placed on top of that, and contains the secondary emitters. If you order the light with no secondary emitters, that board is excluded entirely. In the shot below, you can see the hole cutouts for the primary emitters. Also note the three potentiometers on the secondary board. Using these pots, it’s possible to adjust things about the secondary emitters.
Their brightness, their level of LVP, and something else, none of which the manual covers. ToyKeeper tells me the following about those pots:
FWIW, the 3 screws control the brightness of 3 channels of aux LEDs, not the aux LED board’s LVP level. It should turn itself off at about 3.0V.
The main driver also has LVP, but it’s set to turn things off at about 2.8V, so the 2.9V value used in the review isn’t high enough to trigger the final LVP shutoff. However, even that won’t turn off all the switch LEDs. Two are hardwired to power.
Overall, the build quality is good. The beefy springs on both ends mean it should withstand a bit of abuse.
Size and Comps
Size: 112mm (Length) x 37.5mm (Head) x 26mm (Body)
Net Weight: 125 gram
A couple of in-hand shots.
And I think you really need to know how the reference light (Convoy S2+) fits in my hand for the above shots to be meaningful, right? Here’s that reference photo:
Retention and Carry
Included, but not installed by default, is a black pocket clip. Fireflies recommends dabbing a bit of oil on the clip before installing it, so that the anodization on the light doesn’t get scratched. That’s a sensible move.
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.
A lanyard is also included. It could attach through a hole or areas on the pocket clip, but ideally one would attach the lanyard through this tiny hole in the head.
That’s all that’s included. There is no pouch, and there is no magnet.
Power and Runtime
The E07 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.
Anyway, the cell needs to be capable of high current as this is a FET light, but not too much current, or you’ll fry the emitters (because this is a FET light!). Some of the emitter choices will be ok under higher currents, but the 219b that I have is probably the least capable. I am choosing the Samsung 50E cell, because it’s max current rating is around 10A. Since this light has 7 emitters, and the cell shouldn’t push more than 1.4A through each, things should be ok. (Read on to see if that’s true!)
Also included is an adapter which will allow using 18650 cells. That’s a great option, if for no other reason than your’e probably more likely to have lower current max 18650 cells laying around than you will 21700 cells. (To wit: every 21700 I have except this 50E is ~30A max!).
An 18650 is fairly centered when using the adapter.
Here’a runtime on complete default settings. This is the FET Turbo run. Note the temperature. A head temperature of ~65 degrees C is quite high! Turbo output steps down pretty quickly after a minute or so, but the 30s output is around 3000 lumens!
Below the runtime is of the max of the ramped settings.
The light switches to a very low output, even though there doesn’t appear to be any LVP.
User Interface and Operation
The UI is just like on the Fireflies ROT66. So for the most part I’m just going to paste that UI section to this review.
There’s one switch on the E07. 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!

LED and Beam
My emitters, as mentioned above, are the Nichia 219b emitters. Easily my favorite emitter, I am basically hoarding all the lights that have this emitter. There are 7 of them, and also 6 secondary emitters (purple, in my light).
Here’s some detail on the purple. (Also seen is the PL47, which has teal secondary.)
I often set the light to the stepped option for testing, and that’s the beamshots you see below. The far right is the FET turbo mode. Even on the 10A 50E, the shift to pink is noticeable. It’s probably a bad idea to drive the 219b version of this light much harder than this!
Tint vs BLF-348 (Killzone 219b version)
I compare everything to the Killzone 219b BLF-348, because it’s inexpensive, has the best tint, and [probably] still available! Even though they’re both 219b, some variation is to be expected.
Random Comparisons and Competitive Options….
I’d really only compare the ROT66 to this light. You can see my review on that light here. I like that light as well. The E07 is probably a little more manageable in hand, though.
What I like
- Nichia 219b is an option!
- Some other great emitter choices, too
- 21700 light – I’m liking these more and more
- Package includes adapter for 18650
- Secondary emitters are fun, and great for locating the light at night
- Nice unusual color option (the Champagne/Yellow)
What I don’t like
- Unsure of LVP on the light, and it absolutely needs it (with the always-on secondary)
- Indicating switch doesn’t do enough – I’d like to see it blink battery check, or something.
I’ll have another flashlight on Friday! I don’t have much on tap for Tuesday/Thursday reviews lately, so the focus has been flashlights, of which I have a few!
