Seguin Island lighthouse in Maine is visible up to 14 miles out. The LEDs replaced a 1 KW halogen bulb that was no longer practical when the underwater power line failed in 2019. If you ever wondered what it would be like inside your flashlight, here you go. Do not look into the light.

This is the Z1 Artemis, a recent release from FireFlies powered by a 18650 Li-ion battery, with the FFL5009R 5000K LED, with advertised 2000 lumens and 185m of throw, tail magnet, AUX lights and more!

• My opinion:

The Z1 Artemis is really and awesome flashlight. It was even hard to find things I disliked on it. The LED is really amazing, 5000K with a little of rosy tint, excellent Lume X1 driver, AUX lights with locator and fun RGB, type III Hard Anodizing. It's truly and amazing flashlight with much features designed towards enthusiasts. Loved it.

A point I would like to highlight to that could improve this light even more are: add compatibility with protected cells/cells with USB-C, it would increase size by much, and would make this light even more versatile.

PROS	CONS
Type III Hard Anodizing	Doesn't accept button top or protected cells
Pretty High CRI and awesome tint FFL5009R emitter	Turbo steps down fast, but this is expected on a high CRI high power flashlight like this
Excellent Moonlight mode	*No USB-C charging
AUX with locator and battery indicator
Recessed switch to prevent accidental activations
Excellent Lume X1 Driver

• Price

The Z1 Artemis in Matte Black Type III Hard Anodizing with FFL5009R is currently priced at $57.00 on FireFlies Official Store

• Body and build quality

Anodizing Colors/Material Options: The Z1 is currently available in Matte Black (Type III Hard anodizing), Astral Aluminum, Void White and Polished Brass.

Main body/Grip: The Z1 is super compact for a 18650 flashlight, it almost looks like a 14500 flashlight. The battery tube has a diamond-like knurling, like the X4Q Comet, the head has heat dissipation cut lines, the button area is higher than the rest of the body, making finding the button easier.

Material: The main body is entirely made of 6063 Aluminum Alloy, a more resistant alternative to common 6061 alloy, and this Matte Black version has Type III Hard Anodizing. The Bezel, main button and clip are all made of Stainless steel

Threads: The threads are trapezoidal and anodized therefore, this light has mechanical lock by unscrewing a little the flashlight head.

Clip: The flashlight comes pre-installed with a standard FireFlies stainless steel clip, the clip is sturdy and clips very well. You can easily removed by unscrewing the tail cap where the magnet is located.

Tail stand and rolling: It does not roll much, has the button area is higher than the main body, stopping the rolling, it also has the clip to help. It tail stands and head stands normally.

Magnet: It features a N52 Neodymium magnet, usually used on all FireFlies flashlights, it's one of the strongest Neodymium magnets available; it holds the flashlight pretty well on all surfaces I tested, it, of course, needs a little of steel or other magnetic materials to get a good grip, but as the flashlight is pretty light, the magnet can hold it in almost any orientation. [10th picture]

AUX lights: The Z1 features AUX lights in the TIR and the main button, the AUX is awesome, can be set to very dim or bright and much more. It is controlled by the Anduril UI and can be used as a battery indicator, as a locator to find it in the dark and, of course, for fun!

Buttons: I loved this new flat recessed stainless steel button design, it is, of course, recessed on the body to prevent accidental activations and it fells more premium than the "dome" button other FireFlies flashlights use. The click is pretty nice. It has a white translucent plastic on the center to let the AUX light pass. I don´t know if it's intentional, but when you turn the light ON, a little bit of it illuminates the button plastic center with a green/cyan tint, so you can see the button in the dark, the brightness of it depends on the main light brightness level. [11th picture]

Battery contact: Contact is made with the battery by a Brass button contact with a Beryllium Copper alloy spring plated with Silver on the driver end, and slightly thicker a Silver plated Be-Cu alloy spring on the tail cap. [12th picture]

Bezel: The Z1 uses a standard slim EDC stainless steel bezel, it doesn't have protruding ends and the bezel sits a little higher than the main body to prevent scratches on the lens and main body.

Water Resistance: It features IPX8 rating, O-rings on all threads and glass lens/bezel. I don't see any problems with water resistance, seems perfectly sealed against water. The tail cap is totally sealed against water as it's not unscrewable. The tail cap is actually unscrewable, but has a short thread and it's easy to damage the O-ring there, so I recommend putting some grease there and unscrewing only the head part to swap the battery.

Size comparison: On the left is the FireFlies X4 Stellar, on the middle the FireFlies Z1 Artemis and on the right the Convoy S2+. [13th picture]

• Weight and size

Weight:

- Without battery (with SS clip): 50.3g

- With battery (Samsung 35E): 98.4g

- Battery (Vapcell F38): 48.2g

Size: 92.7mm x 27.9mm x 23.5mm (height x head diamter x tail diameter)

 

• Battery, runtime, and charging

Battery: The Z1 uses a single 18650 unprotected battery, be sure to use a cell with at least 12A CDR for the best performance. FireFlies was kind and sent me a Z1 with a Samsung 18650 35E battery for testing, so all tests will be made with it. Protected cells and batteries with USB-C charging on the cell do not fit on the Z1, making them compatilble with the Z1 would make it more versatile and wouldn't increase size much. [14th picture]

Battery Indicator: This flashlight has 2 battery indicator methods: The classic main light blink, on which the main light will blink the amount of times corresponding to the battery voltage; and the Anduril AUX color battery indicator, the AUX lights will light up to a color corresponding to the battery voltage everytime the flashlight is turned OFF.

Charging: The Z1 doesn't feature charging on body.

 

• Modes, Runtimes, Throw, Candela

Modes: The Z1 has 7 main pre-configured modes, but the brightest one, which I will call L7, can only be accessed momentairly by clicking the button 2 times and holding the button, as this mode is too bright and heats up to fast. All modes, except the Turbo, can be configured into the desired brightness level on Anduril UI.

Advertised specs:

Mode	Brightness (Lumens - Advertised)	Brightness (Lumens - Estimated)
L1 (Moonlight)	Sub-lumen	~0.1 Lumens
L2	-	~10 Lumens
L3	-	~100 Lumens
L4	-	~300 Lumens
L5	-	~800 Lumens
L6	-	~1200 Lumens
L7 (Turbo)	2000 Lumens	~2000

*Estimated brightness by comparing brightness levels from different flashlights, the actual brightness can be different, so use these values as a reference only.

Turbo: Turbo mode is pretty bright for a high CRI emitter in a 18650 battery flashlight, it, apparently, has 2000 Lumens as advertised. It heats up pretty fast as it has much lumens and is a high CRI flashlight. As pointed in the comments, the turbo level can be configured on Anduril to be the top base level, so you could access it normally without it being momentairly.

Moonlight: The Z1 moonlight is, as most FireFlies, amazing. It comes pre-configured with a pretty dim sub-lumen moonlight mode, that can be configured to be even dimmer! Perfect moonlight as usual from FireFlies.

Blinkies: One of the coolest things about Anduril is it´s blinkies modes, I really love the “Candle mode” and the “Lightning” one. You have some fun blinking modes, and others like tactical strobe to choose from.

Lockout: It features electronic lockout on the Anduril 2 UI, by clicking the button 4 times the flashlight will lock and only moonlight will be available for use; and also, mechanical lockout by slightly untwisting the head.

Throw: FireFlies advertises 185m of throw with the FFL5009R LED in 5000K, this light is very floody, so don't expect light to go much far. As you can see on the beamshots on this review, the light can reach around 100m easily on the higher modes.

 

• Emitter, reflector and CRI

Emitter: This Z1 Artemis uses a FFL5009R LED in 5000K. This LED really surprised me a lot, 5000K LEDs usually have a slightly yellow tint, but this one has a slightly rosy tint, it looks SUPER clean, probably one of my favorites 5000K LEDs now. This LED is domeless, but there is a domed FFL5009D version. [15th and 16th Pictures]

Lens: There is an AR coated glass lens in front of the TIR.

Reflector/TIR: The TIR has a clear squares on the area sorrounding the LED and a frosted circle where the LED is, ensuring a floody beam with no donut holes.

Beam profile: The beam is very floody, with a diffused, but present, hotspot that throws light to slightly longer distances, FireFlies rates throw for this model around 185m. [17th Picture]

CRI: The CRI is amazing, having ratings around 98 CRI and 97 R9 as measured by FireFlies.

*I will make a test of this LED CRI, CCT and Lux soon

[20th picture] – Z1 Artemis - L5 mode

I always try to match what my eyes can see on the beamshots, so camera settings may vary.

 

• Driver and UI

Driver: The Z1 uses a Lume X1 32W driver, one of the most efficient and best quality drivers available on the market, with up to 95% efficiency and UDR (Ultra Dynamic Range) technology, providing sub-lumen moonlight modes while also having super bright turbo modes. Excellent driver, moonlights are super dim and turbos super bright.

UI: The Z1 Uses Anduril 2.0 UI, it's a very customizable UI, with a lot of options and settings to have fun with. I will no elaborate much on it as it would extend much the review.

Low Voltage Protection/Warning: The battery indicator will turn red and the main light will flash when the battery level is too low.

Reverse Polarity Protection: This flashlight has reverse polarity protection so you will not damage the flashlight easily by inserting the battery the wrong way.

Temperature Control: It has dynamic temperature control, by default when it reaches 45°C (113°F) it will lower the brightness to prevent driver and LED damage, when the flashlight cools down the driver will allow the flashlight to increase the brightness again. This can be changed on the Anduril UI, but be careful not to damage your flashlight by setting the stepdown temperature too high.

 

A special thanks to Ivy from FireFlies for sending this flashlight for me to review!

*I am not being paid to do this review, everything here is my honest opinion.

Thank you for reading my review <3

 

>Unboxing the Wurkkos K1, a small portable flashlight with multiple lighting modes, ahead of its sale on September 9. This overview highlights the box contents, the flashlight’s compact design, available modes, and what to expect at purchase.

Did a mod to give it a try. Brass and green t6, custom copper spacer with a quad center mpcb, ffl351a 4000k , convoy 3v 10amp driver. I have it set to group 8. This thing is crazy definitely burn hazard which is why I have it set to max at 50% with group 8.

It had a very old lead acid battery inside that I haven't been able to get above 4v but I had success hooking it up to a car battery. Kitten for scale.

S21E BE35AM 3500k
M21F XHP70.3 HI R70 4000k

Went with Vapcell F66 for both.

Now help me with my next order, lol.

My daughter wants one so she’s getting a red T7 4000k (she said she likes that “color” light better), will get it with the 519A and use AA for her.

I want an orange T9, but can’t decide on LED type or which battery. Think I’ll take the F15s as I care more about longevity than pure power. Split between 4000k or 5000k. Given what I have, what would you get?

Lastly, I want one bigger light. 3x21? L21B? Want to stick to two battery types for simplicity. Also going to pick up a Vapcell Q2S-C charger.

Help me make bad choices!

Check out the full comparison with an interactive comparator and a graph viewer:

Convoy L21B | Emitter Comparison

And yes, I do have an L21B F150R on the way. It will receive its own special comparison against other emitters.

I bought a flashlight and it came with a dirt in the reflector, can this interfere with something? Should I complain?

Convoy Brand

Worth noting: the M21K with the 3° TIR and F150R gets an incredibly ringy beam profile that I'm definitely not a fan of. It doesn't look too bad in the beamshots, though it's still quite visible compared to the LHP73B, but in person it's a lot worse than the photos suggest.

I'm also getting fewer lumens out of the 3V 20A driver in the M21K compared to the 20A driver in the other lights I've tested, 4600 in the M21K versus 5200 in the others.

Convoy M21K, 3° TIR — F150R vs LHP73B (4000K)

Emitter	Output (lm)	Lux @5m	Intensity (cd)	Ratio (cd/lm)	ANSI Throw (0.25 lx)	Usable Throw (1 lx)
F150R	4,600	7,787	194,675	42.3	882.4m	441.2m
LHP73B	5,350	4,853	121,325	22.7	696.6m	348.3m

So I normally only carry a few flights at work, but before coming in I was told some a section had gone out so I brought most my lights, to give to the folk on my tours so they could see, I ended up carrying 4.695 Lb of lights for the day, also my obsession with lights was justified for this one very specific circumstance.

List of lights in no particular order: HD02, HD02 pro, TD04, 2 S2+ (one copper one brass), 2 T3 (one UV), T4, S21E, Walmart laser/light thing, a 310nm UV, and a 255nm UV

I googled Chris Ploof and he looks like a jewelry maker that specializes in Damascus jewelry

Two months ago I received this Convoy T8 (didn't take beamshots until a few days ago) and I wanted to showcase it because it's a build combination I haven't seen around here before.

Specs:

Host: Convoy T8 Dark-green.

Emitter: KT CSLNM1.13 (Osram W1 verdure).

Driver: 3V 5A Buck.

Battery: Vapecell K10.

Accessories: Stainless Steel bezel, Stainless Steel screw-on clip.

I don't have and I don't see any real use for this flashlight other than it being fun, but in my mind it was going to be a really cool build with the dark-green and ss parts, and a nice host to try the osram .13 emitter.

I also wanted to test the color difference with the W2 .F1 I have on the S8, and wow. The F1 is a pleasantly green color, but the .13 is an amazing laser green. The .13 has a "tint shift" (if you can call it that) that at higher levels tends almost towards the cyan side of the spectrum that makes it even more appealing to me.

Beamshots:

Same camera settings on all of them, WB: 5200k, they are a bit out of focus. All flashlights at 100%.

Sorry, I don't have any measurements and there are different size reflectors and emitters, but I hope they're useful to someone.

1st location. The T8 and S8 throw more or less the same but the S8 is more useful with a bigger hotspot and a lot more spill. I added a lhp531 4kk s2+ copper shorty that I've got recently.

2nd location. Same as the 1st and the color comparison between .F1 and .13.

*Side note: On the copper s2+, if you replace the original O-ring with a clear one, the bezel halo will project the copper-colored ring that you can see on the road in the 1st location beamshot, pretty cool.
