Armytek Zippy Keychain Flashlight Review

Armytek Zippy Keychain Flashlight Review

The Armytek Zippy Keychain Flashlight, with the “Extended Kit”, is tiny!  Great for keychains but better as a reading headlamp.  Read on!

Official Specs and Features

Here’s a link to the Armytek Zippy Keychain Flashlight product page.


There’s the Zippy, and also the Zippy Extended Kit (seen here).  Both are available in multiple colors:  Blue Sapphire (seen here), Green Jade, Grey Onyx, and Yellow Amber.  There aren’t any emitter choices.


These go for $19 right now at

Short Review

I liked this light much better after I opened it – it’s well built.  As for usage, it’s good enough.  Probably best for reading and not a whole lot more due to that it’s basically a mule.  The headband and all that is good, too.

^ 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.  In the case of this light, I didn’t perform calibrated runtimes.  Basically, I accepted their 160-lumen value and adjusted my graphs to that.  My calibrated setup won’t work well with a light that produces maybe 180 degrees of output.

What’s Included

  • Armytek Zippy Keychain Flashlight
  • Armytek headband
  • Headband mount that includes a magnet
  • Manual

After this first picture, I’ll go ahead and address the watermark you’ll see on these photos.  In the past, I’ve had photos used in a way I didn’t consent to.  Not much more to it than that, and so I’ll leave it at that.

Package and Manual

Build Quality and Disassembly

Build quality on the Zippy is surprisingly good.  It’s a fully plastic body but actually quite rigid.  There are some accessories attached – more on that later.

Two attachments you see here actually detach fairly easily – the black magnet part, and the pocket clip.

The magnet part (which attaches on a ball to the headband) slips out easily, and “locks” into the light magnetically.

This isn’t the magnet you’ll use to stick the light to things.  But the magnet is strong.


With all the external parts removed, it’s a nice tiny slim pocket light.

Just four screws hold the body halves together.  These unscrew easily but hold the body very snugly together.

The little metal loop is held in place by friction here – it is easy to remove once the body is separated.  It’s not held in place by anything.

Size and Comps

59mm x 25mm x 9mm in size, and 12g in weight.

Retention and Carry

Below is the headstrap mount.  This attaches to the light on a ball-type clip-in system.  This clip also offers another belt loop connection option.

The ball allows the light to be oriented quite freely.  There’s also a magnet in this base, so it can be used without the headband altogether.  Thus, the light can be mounted easily and then oriented in just about any direction.

The black plastic mount also has slip-in headband connectors.

The headband is as below.  It’s slim and stretchy, and very branded.

The light doesn’t attach to the headband except on the black plastic piece.

There’s also a metal loop, mentioned above.  Good for keyrings and the like.

Also included is a metal pocket clip, which is removable.  It only attaches in one spot and one orientation (otherwise it’d block something).

This could be a hatlight, but the output would end up pretty close to your eyes, and generally probably not be all that ideal.

Power and Runtime

The Zippy is powered by an internal lipo battery, which is soldered to the contacts.  These are fairly accessible, so technically the battery is replaceable.  (But not really).

Here are a couple of runtimes.  Again these aren’t calibrated, so the 30-second value of “160” and “50” are just taking Armytek’s word for it.

Output on Medium is fairly respectable, holding mostly steady (but still unregulated) for over an hour.

The Zippy also has on-board charging.  There’s a micro-USB port on the side.  A charging cable is not included.

Charging is around 1C, which is good enough.  This takes just one and a third hours.

Modes and Currents

Mode Mode Claimed Output (lm) Claimed Runtime Measured Lumens Tailcap Amps
High 160 17m ^
Medium 50 1h ^
Low 5 10h ^

^ Runtimes were uncalibrated

Pulse Width Modulation

No PWM on any mode (LMH order).

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, which 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

There’s just one switch on the Zippy.  It’s an e-switch, right near the middle of the front.

The switch is very close to the body, and not all that easy to feel without looking.

Here’s a UI table!

LED and Beam

The emitter is not specified in the Zippy.  That said, it looks very much like a Samsung LH351d LH351b, which has been very popular in the enthusiast community.  This sample isn’t the best tint/temp of that emitter, but it’s still pretty good.

I’m not sure what the pad under there is like, but it’s probably not any harder to emitter swap this than any other light.

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

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

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


What I like

  • Good build quality
  • Pretty good choice of emitter
  • Good for book reading
  • Very simple UI

What I don’t like

  • Short runtimes
  • Sort of weird beam profile
  • Switch is hard to find without looking
