DQG Tiny 4th Flashlight Review


I happen to love reviewing DQG flashlights. I’ve reviewed a bunch, and while they aren’t always the best quality, they are often special on some way. This is no different. Read on to see where why!!

Official Specs

The DQG Tiny 4th is the latest edition to their tiny series of portable EDCs. This LED light still weights only 36 grams, measures about 86mm long and therefore is perfect for use as an EDC light. Featuring Cree XM-L2 LED, Tiny 4th produces 850 Lumens with 4 output modes. The TIR lens distributes the bright beam more consistently, giving you a better overall lighting experience. The beauty of the Tiny 4.0 is that you don’t have to sacrifice power for portability.

Upgraded Features:
● Upgraded side switch: Located below the surface to prevent improper operation
● Better heat dissipation allows heat to filter away from the body so that it can stay cool in high brightness level
● Optimized operation: Press to select high, mid, low three outputs, double press for Turbo mode plus instant Turbo mode

Universal Features:
● Cree XM-L2 LED is able to emit a bright 850 Lumens light with a lifespan of 50000 hours
● 4 modes: Turbo – high – mid – low
● IPX8 waterproof rating meaning that it is ready for all weather conditions and can even withstand being dropped in bodies of water
● Low voltage warning reminds users of low power
● PMMA lens provides a better overall lighting experience
● Reverse polarity protection prevents from improper battery installation
● Over 2000000 hours (about 200 years) standby time
● Impact resistance / tail stand capacity / super low 1.5uA standby current


There are two body color versions (Black and Gray) and two tint options (CW and NW) for this light.  Mine is the NW Gray.

Short Review

This is a special little 18650 light. One I’d definitely recommend owning, even if quality could be improved. I like it!

Long Review

What’s Included

  • DQG Tiny 18650 4th
  • Spare O-ring

Package and Manual

DQG doesn’t spend their R&D budget on packaging.  As with most of (all?) their other lights, this one arrives in a very simple cardboard box, with a universal sticker of all DQG models and options, with the light-specific choices indicated.

There is actually no manual.  Other DQG models do include a manual, so I’m not sure if one was accidentally excluded from this box, or if none of these models have a manual.  The UI is simple enough, but some other specs might be nice to have.

Build Quality, Disassembly, and Durability

The one issue with DQG lights in the past is that the build quality.  While this light does work and it seems “good enough,” the build quality is just that; good enough.  If things were cleaned up with this light, it’d be a real huge winner!

Of particular issue is the side switch and how it connects to the board.  This is a tenuous connection, and one that can break.  In fact I had one sample of this light where the switch did break off of the board in the usual way.

The anodizing feels a little thin, and as you can see below is not all that even.  The knurling is very grippy.

It’s possible to disassemble this light very thoroughly.  The tailcap comes off – note the many (“long”) threads.  It takes a lot of twisting to get this tailcap fully seated.  Contact is made early in the threads though, so long protected cells may be used.  Note also the tailcap – there is no spring, but there is a soft donut.

The head and tail come completely off the cell body.  On the head end there’s a brass ring.

That brass ring that goes on the head end is actually for polarity protection.

The mcpcb is removable too.  Remove the bezel and TIR, and it’s possible to push (with a little effort) the mcpcb out of the light (in the direction of the tube).  These mcpcbs are held in place with some …. thermal glue (or the like).


Now we get to the reason this light is special. It’s tiny, for an 18650 light anyway.

Officially the light is 87mm x 25mm.  Due to the thin metal parts, it’s also quite light.


The light comes with a clip installed.  There’s no lanyard, and no real means to connect one except on the pocket clip, where there is a hole down the center.

10 - A0tP87l


The light is powered by a single 18650.  It’ll work with any kind of 18650 (flat/button, protected/unprotected).  In the absence of a manual, I didn’t test my luck with 2×18350 cells.

Output on high is fairly stable, after the steady drop to ~80% output.  Low voltage protection shuts the light off with around 2.75V, which is good.

User Interface and Operation

There’s a single side clicky for operation of this light.  It’s a simple UI.  There are 4 modes, one of which is a “hidden” turbo (ie not in the normal rotation).  From off, click for low.  Hold the switch for mode cycle, and release on desired mode.  From off, hold for turbo (and click to go back to previous mode, or low, depending on how you got to turbo).  From on, double click for turbo.  From off double click for medium.  There are no strobe modes (yay!).

The switch itself is quite small, but rubbery and easy to find.  It’s a little hard to press; one must really get the tip of a finger in there.  But it’s clicky and responsive.


Mode Mode Claimed Output (lm) Mode Measured Lux Tailcap Current [Series Measure]
Turbo 850 8170 2.150A
High 300 5080 0.491A
Mid 80 1642 0.183A
Low 3.5 74 0.011A

Those higher modes are rated at higher amperage, but remember I’m using a series meter, which is likely measuring low.

LED and Beam

DQG has put a Cree XM-L2, with the option of CW and NW.  That emitter is behind a clear TIR optic.  The beam is very spotty – very TIR.  Probably my favorite beam profile, really.  Very broad even spot, with little spill.
