Introduction:

If you stumbled upon this review without knowing what an LEP flashlight is… I’ll do a quick introduction. LEP stands for Laser Excited Phosphor, and it’s using a laser as the lighting source, instead of an LED. The laser shines onto (with the older LEP modules) or through (like this one) phosphor, to change the color and width of the beam. So they don’t look like laser pointers but like regular flashlights. The body and shape of an LEP flashlight don’t look any different from an LED flashlight, but the source of light is.

We’ve reviewed a few dozen LEP flashlights so far, so we’re quite familiar with them. If you want to have the best and farthest-reaching LEP flashlight, check that list.

I’m the first here to admit that this is our first Mateminco branded flashlight we review, but we’ve reviewed many built by the same company, but sold with a different name.

Package quality.

I don’t think the box that I received represents the actual packaging you will receive when buying this. So this is not very important for you, because the actual box and accessories will differ from mine.

  • The flashlight: Mateminco FW2
  • Battery adapter for 18350 batteries

When you buy one, you’ll probably receive a manual, and other stuff. And even the UI is likely to change, unfortunately. So all of our tests are based on the unit we receive, and may not be the same as the actual flashlight you get your hands on. We’ll update the review when we hear about changes.

Flashlight in use

Nonshrouded. That was my first reaction to it.

That may not sound too familiar to some, but it basically means that the tail switch sticks out and there’s no aluminum ridge surrounding it. With most flashlights, you can put the flashlight on its tail end, and the switch doesn’t touch the surface. This one sticks out very proudly.

The switch is reverse-clicky. You have to hear a click to turn it on. Tapping will change modes.

Because of the anodization and lack of knurling, it feels pretty slippery.

Build Quality, and Warranty

In the flashlight communities, we know that Mateminco = Astrolux, so it’s not a surprise that they look identical. At the time of reviewing this light, there hasn’t been an Astrolux equivalent announced yet.

The anodizing isn’t your typical black HAIII but it has a slight charcoal/satin finish and feels slippery. It also doesn’t have the typical knurling, which makes it even more slippery. So keep that in mind. But I do like the shape and design of the flashlight. It looks classic, and futuristic at the same time with the glow tubes installed.

These glow tubes are presumably copied from Lumintop, who has quite a few of those. The main difference between (for example) the Lumintop Thor 2 and this, is that the glow tubes on the Thor are actually illuminated from the inside of the flashlight. So Lumintop’s glow tubes are ‘charged’ whenever the flashlight is used. That’s an interesting design because that means you don’t need an external light source to ‘charge’ these turbo glow tubes. Unfortunately, that’s not the case with this Mateminco, so you still need an external light source to charge them.

Besides that, there is no way to attach a lanyard because it doesn’t have any attachment points. There’s also no pocket clip included with my package.

Warranty? I do not know, since it didn’t include a manual, nor does Mateminco have a website.

LED, Lens, Bezel, Beam, and Reflector

LEPs are available in 2 tastes… sour and … just kidding. There are 2 types, 1 is the classic version with a mirror reflecting the laser onto phosphor, and the newer one with a translucent Phosphor layer and the laser shining through the phosphor. The Mateminco FW2 is the latter type, which makes it thinner and shorter than the older mirror modules.

So in that regard, I welcome the newer types, but in terms of performance, the former ones are generally speaking still better performers.

The bezel protecting the glass lens is flat, and has the same color anodizing, and is likely aluminum. I’d like to see some more lego-able flashlights where you can mix and match certain parts of the flashlight. Kind of like with the older P60 style, where you have all sorts of switches, tailcaps, bezels, heads, etc.

There is a glass protective lens in front of the convex lens, so that’s a good thing. Replacing a standard glass lens is much cheaper and easier to find, than a convex lens with the right angle.

Driver & User Interface:

The driver in the FW2 has 3 modes… but not the greatest UI

Fortunately, I did all the testing before I broke the light, but I can’t test the UI fully, because that’s too late.

Available modes:

  • Low, High
  • Strobe

From OFF:

  • Single-click: Turn on

From ON:

  • Half-press: Toggle between Low and High
  • Single-click: Off
  • Double tap: Strobe

Shortcuts:

  • To High: none
  • To Low: none
  • To Strobe: double click from on

Mode memory:

  • It looks like it doesn’t have mode memory, and always starts in low.

Blinky modes menu:

  • Yes, double click for Strobe.

Low battery warning:

  • No

Lock-out mode:

  • Not that I know off

PWM:

  • Not visible

Conclusion:

I don’t particularly like the strobe so easily activated. I know, you only have 2 modes, so why would you tap twice… but hey, I like playing with that switch.

Batteries & Charging

Well, the good thing about the FW2 is that you can either use a 18350 or 18650. There is one dedicated tube for each battery, and no extension tubes are needed, unlike some other brands. I personally don’t like using extension tubes, so it’s great to have 2 dedicated battery tubes instead.

18350: you can only use short 18350 batteries, like unprotected, without a USB port. I tried a Weltool UB18-12P and it won’t work. Short batteries like unprotected Keeppower 1200mAh IMR18350 fit perfectly.

18650: Don’t try to use protected 18650’s!

Mine broke because of trying to use a protected battery! I tightened it, and it didn’t turn on, tightened a bit more, still nothing. Then reverted back to the unprotected cell, and that didn’t work anymore either. Tried the short tube with 18350, also didn’t work anymore. So learn from my mistake, don’t use protected cells, and try to tighten the tailcap.

Performance

Lumen measurements:

All output numbers are relative to my homemade Integrating Sphere. It is set up with an Extech SDL400 Lux Meter for measurements including a Kenko PRO1D ND-16 filter. The base measurement is done with a Convoy S2+ that has been tested at 255 lumens.

For Amp readings, I use a Fluke 77III DMM. For higher amps I now use a Fluke 325 True RMS clamp meter. For microamps, I use a cheap DMM with an easy-to-use micro amp setting.

Used a Samsung INR18650 30Q for testing.

Parasitic drain:

  • Didn’t measure parasitic drain before it broke.

Runtime:

The runtime test was done with the 50cm integrating sphere, including the Kenko Pro1D ND-16 filter and Extech SDL400 data logging Lux Meter.

High: total runtime 1h18min.

Low: 3h02min

And I did 1 test with a 1200mAh battery, and the total runtime for High is: 28min. You can see the graph below. The output drop happened at the same time as with the 18650 battery.

Throw Measurement

Measurements were taken outdoors at 20 meters, with a professional Hagner E4-X Lux Meter. Measurements were taken 30 seconds after turn on.

Reviewer Marco

4 stars: ★★★★

Activating strobe is a little too easy when changing modes. But performance-wise, the Mateminco is not a bad flashlight. Not as good as some of its competitors, but it’s very pocketable.

The additional 18350 battery adapter is a great option as well. That makes the light even shorter, and even more ‘pocketable’.
