Lumintop FW3A

Lumintop FW3A review (BLF & TLF) triple XP-L Flashlight (2800 Lumens)

Introduction:

This is one of the most anticipated flashlights of 2019. A team of BLF and TLF members started the build of this flashlight back in 2017. Lumintop stepped in to be the manufacturer of the flashlight. The project started back in 2017, with a total of about 3000 lights on preorder.
The Lumintop FW3A accepts 18650 batteries with a size of a normal 18350 flashlight. Yes, it's that tiny. It is probably one of the shortest 18650 flashlights on the market, or even The Shortest.

You looking for a short flashlight, that takes 18650 batteries, using a Triple XP-L, a pocket clip and 2,800 Lumens? Than definitely take the FW3A into consideration.

What you'll get:

  • Lumintop FW3A
  • Box
  • Spare O-rings
  • Manual
  • Pocket clip (already attached)

Handling of the light and knurling

The BLF/TLF team has been putting their heads together to come up with the best bang for the buck and the shortest possible 18650 light with a triple XP-L engine.

That being said, the Lumintop FW3A is definitely a short flashlight. It's actually one of the shortest 18650 flashlights on the market. It's barely longer than an average 18350 or even an AA flashlight. This makes it a great EDC flashlight. That being said, you shouldn't think this is one of the best tactical flashlights out there, since it's not tactical. The UI is too complicated to depend your life on! I would never use this a a self defence (tactical) flashlight, ever. It's great for every day carry, or for camping though.

The body is smooth and tapered so there is only knurling on 2 parts of the body, the head and tailcap. The switch is an electronic switch without a 'click'. Mine also squeeks, and I will try to find a way to get rid of the sound, but it might be the design of the switch.

Pocket clip
The pocket clip was already attached when I received the light. It's pretty stiff, and seems like good quality.

Warning: 
Please do not take off the tailcap, since you might end up losing small parts of the tailcap and ruin your flashlight.

Tailstand?

  • Totally cool, since the button (switch) is not protruding.

Build Quality, anodization

Lumintop makes some great products, and the FW3A seems to be a great fit to their current line up. Knurling and anodization are done well. No missing spots or blemishes can be found anywhere on the light.

One thing I'm not really sure about is the switch. After taking the tailcap apart and putting it back (right after I received the package) the switch felt really uncomfortable. It squeaks when you press the button from the side, and it misses that "clicky" feel that I am used to with other flashlights. I complained in the Budgetlightforum thread, and it seems that there were a few batches with this "sqeaky" sound and a little uncomfortable switch.

In the second row of pictures you can see the rubber button. In the center of the rubber button is a very tiny piece of rubber that can be taken out. Make sure you don't lose this! Or your switch may not work properly anymore.

Lumintop now also offers different versions:

Lumintop FW3A Titanium

Lumintop FW3A Copper

Besides these special editions, they also have a Green version, a Purple and a Blue

Lumintop-fw3a-blue-purple-green

Threads and O-rings

On both ends of the battery tube are O-rings. They are lubed and fit well. Threads are not annodized except for the one near the bezel. The threads run really smooth, so that is nothing to complain about!

LEDs, Lens, Bezel and Reflector

If you are trying to replace the Bezel, lens, or reflector for the Lumintop FW3A, you may be disappointed. Why? Because the FW3A doesn't have all those!

It's using a matte Carclo 10511 TIR optic to smooth out any artefacts in the beam.

I chose for the  Cree XP-L HI 3D (NW 5000K) since that was the brightest option in a Neutral White tint. It's also available in Nichia 219 Hi CRI, but I just wanted a bit more punch. I prefer NW over CW for general use. CW is needed to reach maximum output though, and I only have 1 WW (warm white) light in use. And it's currently used as my kid's bedside flashlight. It's not used often these days, but it's great for darker areas without 'hurting' your eyes, or waking up somebody!
But here I chose for a NW LED!

Dimensions:

This is one of the main characteristics of the Lumintop FW3A. Accepting a 18650 battery in a 18350 sized body. Amazingly short for this type of light. Flashlight manufacturers mainly show dimensions in millimeters. Since the body is tapered, it's kind of difficult to show a "body diameter". If you look at the pictures below, take a look at the difference between the Nitecore MH25GTS and the FW3A

  • Length : 92.5mm / 3.6"

Weight:

  • Weight empty: 53gr / 1.8 oz.

User Interface:

One of the reasons this light is so popular, is because of its Anduril UI. This UI has been put together by BLF member ToyKeeper. She has been groundbreaking with her fully programmable flashlight firmwares. Many flashlights currently use this UI, since it's a mix of ease of use, and programmable at the same time.

When you receive the Lumintop FW3A, you'll notice that the default menu is a simple stepless dimming mode. When you press the button it ramps the brightness up really smooth, en repeat to ramp its brightness down again.

For Download: You can check out the full Anduril UI manual here

From OFF:

  • Single click: ON
  • Double click: Turbo
  • 3 clicks: Access the blinky / utility modes.

Enter Special/Fun modes from OFF:

Protection Features (Low Voltage Protection)

LVP makes the light step down to a lower level when the battery is low, and if the light is already at the lowest level, it shuts itself off. This activates at 2.8V. LVP adjustments happen suddenly..

Thermal regulation attempts to keep the light from overheating, and otherwise adjusts output to stay as close as possible to the user-configured temperature limit. Thermal adjustments happen gradually, in steps so small they are difficult for humans to perceive.

Lumintop FW3A Troubleshooting

If for some reason you have found that the FW3A is acting up, follow these steps:

  1. Make sure the battery is fully charged
  2. Make sure head and tailcap are tightly screwed down
  3. Make sure if you have a Turbo mode (if not, you are probably in Muggle mode)

Batteries and charging:

Warning:
Insert the batteries from the top, not from the tail. If you do it from the tail, the switch may fall out! Make sure the positive terminal of the battery is pointing towards the head!

To keep cost down and maximize the potentials of this little gem they decided not to include a charging system. So if you are looking for a flashlight with a built-in charger, this may not be your best choice.
Powering 3 pieces of the CREE XP-L, you need some serious power, and that can be provided by using a single High Amp 18650 battery, like the Samsung 30Q, or Sony VTC4, VTC5 etc.
These are great batteries for maximize it's output!

Non-protected batteries only

Since Lumintop kept the body size as short as possible, you can't use any protected 18650 batteries. You need to stick with high amp non-protected batteries.

Performance:

Many people are mostly interested in this part, and I can totally understand. This part makes reviews so interesting. It's always interesting to see if the claims are actually true. Many cheap flashligts you can buy on eBay make some rediculous claims. Major brands like Lumintop don't do that as much. But at the same time, I have seen time after time that even the bigger flashlight makers tend to exaggerate a bit. Because why showing 9100 Lumens if you can just show 12000 Lumens. But anyway, let's take a look wat this bad boy has to offer.

Runtime:

Runtime was taken using a pink Samsung 30Q 18650 High Amp battery. The runtime was taken with Max Output (not Turbo). It has almost no meaning of doing a runtime test with these kind of flashlights, since everyone is using a different battery, but to know how the flashlights behaves etc. a runtime test can be very helpful.

runtime graph of lumintop fw3a

The output drop took about 8 minutes from max to a pretty stable 17%. The rough graph for the first hour has to do with the setup. I put the light + phone in a box, so the light bounces around. If I moved the camera (lightsensor) 5 mm to the left or right, the numbers would be different.
If you do a runtime test, its better to do it in a integrating sphere. But mine isn't set up for that. Still have to make a box to fit my 50cm styrofoam ball.

Runtime was 452 minutes (7.5 hours) for the first major drop. And then another 20 minutes till its about 1% output. 7.5 hours of runtime at about 160 Lumens.

Low Voltage Warning

There is a low voltage warning at 2.8Volts according to the Andruil firmware manual. During my runtime test it went down to 2.93V, but it didnt turn the light off yet.

PWM:

  • Nope. At least I couldn't detect it by eye.

Throw:

Throw was measured indoors at 5 meters. The battery used was a Samsung 30Q, fully charged. The highest lux number I got, I recorded. Lumintop says the throw should be 10.000cd, which I easily surpassed. Theirs might be measured with different LEDs, optics or tint.

  • Lumintop FW3A throw measured at 5 meters: 18500 cd

Overall conclusion

Pros:

  1. Extremely short 18650 flashlight
  2. Anduril firmware with great amount of options
  3. Affordable

Cons

  1. non-protected batteries only
  2. squeaky and uncomfortable switch (my copy)

Overall Rating: very good

If you are looking for an EDC flashlight and really like to use the capacity of a 18650 battery in the smallest possible form.. have a look at the Lumintop FW3A. It's far from perfect, but for the characteristics and price this one is hard to beat. 2000+ lumens, a pocket clip and the size of an AA flashlight, makes this one of the most popular and talked about flashlights of 2019, and maybe even 2020.
