Package and Manual

I’m not sure this is the officially official manual. But it’s the one I have.

Build Quality and Disassembly

The FLGEDC MR01 long-range flashlight is made of 6061-T6 aluminum alloy, and anodized in an interesting splatter pattern. (In years past, I think we decided to officially call this a “splattern” right?)

The light is very slick in the “twisting” direction, but the body ridges offer great grip in the “slipping out of hand” direction. So this is a bit of a wash on grip. Good one way, slick the other.

This isn’t really a tactical light, so having a spring only on the tail end is acceptable. The positive connection is a button.

The cell tube is not reversible. And look how long those head threads are! Because of this, it’s much easier to unscrew and remove the tailcap for cell swaps.

The bezel has some interesting cutouts. I had to say these seem like an afterthought, but they don’t really seem to provide much function.

The cooling fins on the head are very deep! These should provide good cooling.

Size and Comps

Length: 147 mm
Head Diameter: 41 mm
Body/Tail Diameter: 29 mm
Weight: 180 g without battery

Here’s the light in hand:

Here’s the test light with the venerable Convoy S2+. This is a brass version, which is a good bit heavier than aluminum, but has the same dimensions: 24mm in diameter by 117.5mm in length.

Also in the photo above, my Standard Reference Material (SRM) flashlight is the Hanko Machine Works Trident, an 18350 light. While I have not reviewed or tested the Gunner Grip version seen here, I have tested a Hanko Machine Works Trident Total Tesseract in brass. I love the Trident, and it’s a striking contrast to the inexpensive Convoy S2+, another great SRM.

Retention and Carry

The FLGEDC MR01 long-range flashlight includes a lanyard, which can attach only through these two holes in the tailcap.

I’m glad there are two holes, because when properly installed, the FLGEDC MR01 long-range flashlight should still be able to tailstand.

That’s it – there is no pocket clip, magnet, pouch, or anything else.

Power and Runtime

The FLGEDC MR01 long-range flashlight runs on a single lithium-ion battery. My kit and I think all kits included this EVA 50E 21700. It’s a standard flat-top cell.

It goes into the FLGEDC MR01 long-range flashlight in the usual direction: positive terminal toward the head.

Below are runtime tests on the highest four modes. Performance is good, and the stepdown even on Turbo is after a reasonable time at the highest output. Medium of 1000 lumens steady is the real star, though.

The test above should be “Medium1” and the test below should be “Medium2.”

The temperature lines in these charts are included as general context, not precise measurements. The values represent the range (min to max) during testing, but should not be taken as exact readings. A temperature sensor is not always attached to the bezel (or even the hottest spot, assuming that could be defined). Even with ideal placement, too many variables affect temperature to definitively state a specific max value.

Charging

The FLGEDC MR01 long-range flashlight has a USB-C charging port on the head. This port is on the opposite side from the e-switch, and there’s a good chance they can be confused. But the charging port cover is flat.

A cable is included for charging. It’s A to C.

Charging C to C looks great. A to C is fine too. Both finish in under 3.5 hours.

Modes and Currents

Mode	Mode Claimed Output (lm)	Claimed Runtime	Measured Lumens	Tailcap Amps
Turbo	2000	5m+105m	1912 (0s) 1773 (30s)	5.05
High	1450	8m+110m	1415 (0s) 1399 (30s)	4.24
Medium1	1050	120m	997	2.44
Medium2	540	4h30m	512	0.97
Low	200	13h30m	186	0.30

Pulse Width Modulation

None of the modes use PWM. What you see below is probably SMS ripple.

Click here to see a “baseline” – a chart with almost no light hitting the sensor.

Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.

User Interface and Operation

The FLGEDC MR01 long-range flashlight has two switches. The first is a tail mechanical switch that serves as a mechanical lockout. If this switch isn’t “on,” the light will not do anything!

That shroud completely protects the switch from side access. It also allows tailstanding.

The other switch is a side e-switch. It does appear to have an indicator feature in the center, but I’m not sure there’s an LED under there.

Here’s a user interface table!

State	Action	Result
Tail switch off	Any e-switch action	No change
Tail switch off	Click tail switch	Mode memory (including “off”)
Tail switch on	Click tail switch	Light is off
Tail switch on	Click e-switch	Iterate no output (faux-off) and output (memory)
Tail switch on, light on	Hold e-switch	Mode advance (excluding Turbo)
Tail switch on, light on	Double click e-switch	Turbo
Tail switch on, light on	Triple click e-switch	Strobe
Tail switch on, light on	Click e-switch	Faux-off

I just double-checked the indicating e-switch, and it DOES light in blue (for certain), and probably red. But it’s very faint. So faint you’ll wonder if it’s just light from the main emitter bleeding through inside the body. But the indicating switch does (seem to) work.

LED and Beam

The FLGEDC MR01 long-range flashlight uses a Luminus SFT40 emitter at 6500K. The light has a smooth, wide, and deep reflector. It’s a good combo to help the light live up to the “long-range” moniker.

Optional, FLGEDC includes three filters.

They have a hinge, so you can use the light as a white output light, or with one (at a time) filter color.

The three filters are amber, green, and blue.

LED Color Report (CRI and CCT)

The CCT is cool white, but not as bad cool white as we might imagine. Often, when a brand claims 6500K, what we actually see is >7000K. Not the case here, with the highest, hardest-driven mode hitting around 6700K. CRI is low.

CCT (Correlated Color Temperature) refers to the measurement of the color appearance of light, expressed in Kelvins (K), which indicates whether the light is warm (yellowish) or cool (bluish). A lower CCT (below 3000K) is considered warm light, while a higher CCT (above 5000K) gives cooler, bluish light.

CRI (Color Rendering Index) is a measure of how accurately a light source renders colors in comparison to natural sunlight. Scored on a scale from 0 to 100, higher CRI values indicate that colors appear more true to life and vibrant, similar to how they would look under the sun.

Beamshots

These beamshots always have the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.

There’s surprisingly little difference in feel between the highest two modes. The lowest mode is also remarkably bright.

Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)

I keep the test flashlight on the left and the BLF-348 reference flashlight on the right. These photos are taken around 18 inches from the door.

I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!

Summary and Conclusion

The FLGEDC MR01 long-range flashlight is a capable long-range flashlight with excellent output and, more importantly, impressive sustained performance. Medium 1 holds nearly 1000 lumens for two hours, a highlight of this light. Build quality is good, USB-C charging works well, and the optional color filters are a fun extra. The cool-white, low-CRI SFT40 is ok, and not as cold white as it could be. And I just don’t love the implementation of the mechanical tail switch and side e-switch. At $59.99, there’s a lot to like here, particularly if sustained output and throw are your priorities.

All my FLGEDC reviews!

^ Measurement disclaimer:  Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.

What I like

• Excellent sustained output, particularly Medium 1
• Good runtime and reasonable Turbo stepdown
• Impressive throw
• USB-C charging
• Includes a 21700 cell
• Useful cooling fins
• Optional color filters are a fun addition
• No PWM

What I don’t like

• Cool-white, low-CRI output
• Slick body in the twisting direction
• No pocket clip or magnet
• Two-switch operation and mechanical lockout are unnecessarily complicated
• Very faint switch indicator
• Bezel cutouts don’t seem to serve much purpose
