Lumintop EDC 2AA Flashlight Review

Lumintop EDC 2AA Flashlight Review

The Lumintop EDC 2AA is a flashlight with an interesting user interface. It runs on 2 AA cells (1.5V only) and has a Cree XP-L2. Read on!


Official Specs and Features

Here’s a link to the Lumintop EDC 2AA flashlight product page.

Versions

I believe there’s just one version of the Lumintop EDC 2AA flashlight.

Price

Looks like the going price for the Lumintop EDC 2AA flashlight is around $31. Lumintop’s official site has it for $30.95.


Short Review

I’d say this isn’t the most interesting or exciting light that Lumintop makes, but the user interface feature is pretty neat! Depending on how tightened the head is, you are accessing either three steady modes or two strobe modes. It’s a nice feature if you need that!

^ Measurement disclaimer:  I am an amateur flashlight reviewer.  I don’t have $10,000 or even $1,000 worth of testing equipment.  I test output and such in PVC tubes!!  Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).

Build Quality and Disassembly

Below you can see how the interesting user interface works. If the head is tightened so that the ring on the MCPCB and the threads are touching the cell tube, you’ll have the steady modes. If you loosen the head so that only the threads are contacting, you get the strobe modes.

The tailcap has a nice beefy spring.

Overall, the build quality here is just fine.

Size and Comps

Size 148 x 22mm
Net Weight 76g

If the flashlight will headstand, I’ll show it here (usually the third photo).  If the flashlight will tailstand, I’ll show that here, too (usually the fourth photo).

Here’s the test light with the venerable Convoy S2+.  Mine’s a custom “baked” edition Nichia 219b triple.  A very nice 18650 light.

Also above is the light beside my custom engraved TorchLAB BOSS 35, an 18350 light.  I reviewed the aluminum version of that light in both 35 and 70 formats.

Below you can see the Lumintop EDC 2AA flashlight beside another 2xAA light I’m playing around with right now. Fairly different lights, though.

Retention and Carry

The Lumintop EDC 2AA flashlight has a friction-fit pocket clip.

It allows quite a deep carry, too.

The tailcap has holes for attaching a lanyard, but no lanyard is included.

Power and Runtime

Lumintop includes the type of cells that are needed for the EDC 2AA flashlight. Those are AA cells, of the “primary” (disposable) variety. I tested with the NiMH cells seen below – Amazon Basics. They’re good and fine cells for this light! If you want to check them out, use my referral link to amazon, for the Amazon Basics rechargeable NiMH AA cells!

Honestly, the fit is very snug with these cells… Primary cells can be inserted through the head or tail, but these Amazon Basics would only come and go through the tail!

Here are a couple of runtime graphs.

I didn’t really observe low voltage protection.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps (@3V)
High 450 35m 506 2.00
Medium 80 6h30m 70 0.28
Low 3 168h 5.2 0.01

Pulse Width Modulation

The mode order used by the Lumintop EDC 2AA flashlight is HML, so below, the PWM graphs are in that order. High is at left. Both of the lower modes have PWM and I’d say it’s PWM at a speed that isn’t all that desirable. If you’re sensitive to PWM, you’ll likely notice this PWM.

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.  Also, here’s the light with the worst PWM I could find.  I’m adding multiple timescales, so it’ll be easier to compare to the test light.  Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, with is 50 microseconds (50us).  10ms5ms2ms1ms0.5ms0.2ms.  In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line.  I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too.

User Interface and Operation of the Lumintop EDC 2AA flashlight

There’s a single switch on the EDC 2AA. It’s a mechanical tail reverse clicky.

Here’s a UI table!

State Action Result
Off (with head fully tightened) Click On (Mode Memory)
On (with head fully tightened) Tap Mode advance (High Medium Low order)
On Click Off
Off (with head loosened a bit) Click On (Mode Memory; Strobe or Beacon)
On (with head loosened a bit) Tap Mode advance (Strobe or beacon)

This is a very uncomplicated user interface.

LED and Beam

Lumintop has used a Cree XP-L2 emitter in the EDC 2AA.

That emitter is coupled with a smooth reflector, and the bezel has a bit of a shape so that light will escape while headstanding.

LED Color Report (CRI and CCT)

The output is very cool, ranging from 7500K to nearly 8000K. That’s not ideal, I would say.

Beamshots

These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.

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.

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

Conclusion

What I like

  • Great size and shape in hand
  • Very simple user interface
  • Can avoid strobe modes completely if you wish to
  • Runs AA cells, including NiMH

What I don’t like

  • Very cool white output
  • High medium Low mode order
