Intro

When it comes to exotic flashlights such as this beast, supply is limited to certain stores. Wallbuys happened to offer this flashlight for the lowest price, and appeared to be a reputable distributor of flashlights amongst other gadgets.

I have been asked on multiple occasions about my enduring obsession with flashlights, and more specifically, owning the most powerful flashlights. I have also been asked why I spend so much money on flashlights, and this light is a prime example. Many people could not imagine spending over $200 on a flashlight, for obvious reasons. However this light is not just a flashlight. This light is the pinnacle of exotic “pocket-sized” flashlights; the offspring of motivation, inspiration and a passion for wickedly bright flashlights. And whilst this flashlight may not be the most practical in many situations, it represents perfection and the human desire for improvement and “more”. That being said, this light would be suitable for caving, hunting, and search and rescue operations.

Fire-Foxes is a Chinese owned company that specialise in HID flashlights, despite also selling LED flashlights. The predecessor to this flashlight is the FF3, which is also an amazing flashlight. Their flagship flashlight, the FF4, is recognised as one of the world’s most compact HID flashlight. Let’s have a closer look.

Initial impression (Unboxing)

Wallbuys shipped this flashlight in its retail box, enclosed with Styrofoam in another cardboard box. Despite their fantastic packaging, the inner box was slightly crumpled at one corner, although the thick foam that surrounded the flashlight ensured that it was nice and safe. The retail box also contained a piece of fluoro paracord (black would have been better?), a lens cap, a spare reverse-clicky switch, an information pack and of course, the flashlight.

The information pack consisted of a Chinese Manual, warrantee cards as well as an authenticity verification card.

The lens cap appears to be a camera lens cap for 67mm diameter filter threads, and is attached to a handy string. The addition of the lens cap is a unique touch of elegance that looks cool as well as being functional.

Build Quality

I was surprised by how light the flashlight was when I first picked it up. Weighing in at a mere 500g without batteries and just over 700g with, this is one of the lightest HID flashlights. Despite this, the build quality was superb; the machining was perfect, threads were cut nicely (albeit a bit dry) and the reflector was spotless.

The design in general is quite eye-opening; the beefy heatsink on the head, the rubber covered clicky switches, and the rectangular cut knurling all look fantastic. Grooves are cut out of the primary heatsink to prevent rolling. “Fire-Foxes® FF4” is laser engraved onto the head, and on the other side, “Caution hot” (wise words of warning as this beast does get quite toasty after a while). This light tailstands very well.

The anodisation is outstanding, and is very matte unlike the Skyray King. This is probably the best anodisation that I have ever seen. There are no missing patches or scratches to be seen anywhere.

The threads are of a round cut and are anodised like the body. Possibly the only complaint I have about this flashlight is about the dryness of the threads and o-rings. This is an expensive flashlight; would it really be that difficult to lube the threads at the factory? The harsh creaks that I heard as I unscrewed the tailcap were subdued by some synthetic motor oil, and a good cleaning. It may be the anodisation that caused the squeaking, which is quite reasonable.

The pair of switches that tame this stallion are positioned on the bottom and side. Both are covered with a silicone boot. The side switch is black, and is surrounded by a thick stainless steel ring secured by four hex screws, adding to visual aesthetics. This switch seems to be a momentary switch, similar to the SRK. The bottom switch is a reverse clicky switch covered by a true GITD tailcap that illuminates when it is activated (more about that later). Both switches have a very solid tactile feel and seem to be of good quality.

The reflector is a SMO reflector, and is made of high grade polished aluminium. The reflector is flawless; there are no bumps, impurities or scratches, allowing for maximum efficiency. The custom parabolic design is suited for HID lamps, and as a result the shape is distinct from LED reflectors. The bulb is centred perfectly, allowing for a clean, circular beam pattern. Kudos to Fire-Foxes for perfecting the reflector!

The lens of the flashlight is made of uncoated glass, which is slightly disappointing. All lights in this price range should have an AR coating, and many do, but this doesn’t. Bummer.

Size comparison (From the left: Skyray King, Coca-Cola, Fire-Foxes FF4)

Overall, this flashlight’s build quality is by far the best I have ever seen. The only shortcomings were the dryness of the threads (although to be fair not many flashlights come with lubed threads) and the uncoated glass.

Operation

This light accepts 4 unprotected 18650 batteries, which appear to be wired in parallel (poles are aligned), but are actually wired in series. Four Li-ion batteries wired in series can be a ticking time bomb if the batteries are not matched, therefore care must be taken to ensure that good cells are used. Batteries with protection PCBs will not fit, though trimming the springs will allow for protected cells to fit. The battery carrier houses a protection circuit, as well as the clicky switch. The carrier is built quite solidly, with solid copper positive contacts and thick gold plated springs. The carrier sits flush with the body tube of the flashlight; there is no rattling at all when the flashlight is shaken.

Battery carrier

Due to the high current draw, good quality cells should be used with this light. Many recommend the Panasonic NRC18650B (3400mAh), which provide adequate current and a fairly long runtime (1+ hours on 40W).

This light has 3 modes; high (40W) and low (24W), with a hidden turbo mode (60W). The quoted luminous outputs are 2000, 4000 and 6000 lumens respectively. I do not own a light meter, though others have confirmed that these ratings are quite close to the actual output. On click of the tail switch illuminates the green standby LEDs under the tailcap, and puts the light into standby mode. A press of the side switch initiates the ignition of the lamp at 40W. Being an HID flashlight, this light requires about 10-20 seconds to warm up to full brightness. A second press lowers the lamp down to 24W, and any further presses switches between these two modes. A long press of the side switch while in low mode brings the light into turbo mode. Turbo mode will cause excessive heat to be produced, therefore after a few minutes in turbo mode, the temperature sensor will trip and bring the light back to 40W mode. The light will step down to low mode when the batteries are nearing depletion, or if it gets too hot.

Even the 24W low mode is enough to blow many LED flashlights out of the water. The Skyray King cannot compete, neither can the Ultrafire C series or the HD series. The eBay HID had more throw (bigger reflector), but its 85W mode was equivalent to the 60W mode of the FF4. The eBay HID also had a comparatively colour temperature, 6000K, compared to the much more pleasing 4300K of the FF4. Side by side the eBay HID’s spot seems blue.

At 60W, this light outputs enough photons to blind a bear. The amount of light emerging from this tiny flashlight is incredible, and cannot be described with words. It truly is pocket sunshine.

The ballast would consume an extra 25% of the nominal power output, but the light is still very efficient.

At 60W the FF4's beam completely destroys the LED lights in terms of output. The 85W eBay HID is comparatively bright, but the colour temperature is much higher.

Outdoor beamshots are taken in a suburban backyard. Trees are around 50m away. Back fence is around 15m away. All photos have been taken with ISO 1000, f/4.8 aperture, and 1/8" shutter speed.

The throw on the FF4 is definitely not as concentrated as the eBay HID, although the wide area illuminated is as bright as the spot that the eBay flashlight illuminates. This light is a photon cannon.

Conclusion

This light is just amazing. The build quality is amazing, the light output is phenomenal, and the compact form factor makes it even better. Obviously, this flashlight is not for everybody, but for those who are true flashlight enthusiasts, there is nothing else this small that comes close.

This is my first experience shopping with Wallbuys, and I must say that I am very impressed with their service. The staff were professional and courteous when I queried about the product. They shipped the flashlight on the same day that I ordered it and it arrived within 2 weeks!

This is not a budget flashlight. That is why I took off 0.5 from the score. But even so, it is worth every cent for every eye-searing lumen in the portable form factor. I recommend this light to anyone who is looking for the brightest “pocketable” flashlight, because it truly is!

Great photos, thanks for the review. :slight_smile:

Amazing! can you get spare parts if needed?

To my knowledge doingoutdoor.com sell a spare battery carrier. As for the rest, I’m not too sure.

The bulb has a ~2300 hour lifetime, so sooner or later that will need replacing. I haven’t heard about anyone selling a spare FF4 bulb.

Plus there's a ballast that could go bad as well. I'll tell you though, it's very tempting to buy one of these. I can't believe how bright it is! Totally insane!

Thanks for the review. I was looking for a review like this before I bought mine but there wasn’t any good ones around.

I agree with all you have said. My FF4 still blows me away when I use it. Everyone else I show just stands there shocked at its output.

nice light… but how long can you use it before it shutdown by itself?

the light is just: wow!

thanks for the review

Thanks for the great review. Look at that gorgeous tint when compared to SRK!

Congrats on that awesome light and thank you for a great review. I've wanted one of those lights since I first laid eyes on one. You just made me want one even more.

HID's don't get much love here. Nice to see there are a few HID fans still around.

The ebay HID looks to have just slightly more throw, but that FF4 really shines with the massive flood and very respectable throw.

I imagine it has something to do with the reflector. My [generic 75w HID] has a pretty cheap reflector, but that ff4 reflector looks dang near perfect.

I like that it uses 18650's instead of cheap chinese priority crap . This may be my next major flashlight purchase...

Whoa! 8^°
droooll….
…but costly…

Not in any way possible to adjust the focus, by moving the bulb more in or out somehow?
I like the big flood of light though!

PS:
Advantage of dry threads is you can drop parts in sand or what not, won’t stick in the threads when dry.

For sheer power, with plenty of throw, currently nothing beats this light, relative to size.

Theoretically, if one were mechanically inclined, one could make a reflector extension to screw into the light... reduce the spill, and probably gain quite a bit more throw.

I know a lot of people that had purchased this light or any other HID have gotten rid of them because of the 10-15 sec warm up time. But even while warming up the lights will still output more light than many high-output LED lights. The FF4 is around 7000 Lumens on turbo and I measured 428K lux.

Even though I probably haven’t used my lights nearly as much as they deserve, I’m still keeping them. The ability to switch between modes on the FF4 is a huge advantage over the FF3, but, I actually prefer the simple single on/off operation of the FF3 and it has much better balanced feel. FF4 has a SMO reflector and FF3 has LOP.

Anyone considering one of these should first check this out:

More output, smaller, LED, but much less throw I’m guessing.
Even more expensive though…

The difference in the throw will be huge. The MM15vn will be a flood monster, with ok throw dedomed, probably around 40kcd, but that pales vs the FF4 throw with 400kcd+.

This, and the VN costs more. I imagine it wont handle the heat those emitters produce as well as the HID handles the minimal amount of heat generated.

It really depends on the batteries used and the mode.
With Panasonic 3400Ah NCR18650B, runtime should be 60+ minutes on 40W before it shuts down, and probably 75+ minutes on 24W.

60W shuts off within 5 minutes no matter what batteries you use, due to the thermal switch being tripped.

Although the thermal switch would probably trip before any of the aforementioned runtimes are reached

True, the MM15 will be a ridiculous wall of light, like a SRK on steroids. I imagine the FFIV would be like a TK75 on steroids (alot of throw and spill)
