Lumintop ODF30 Flashlight Review

Preface

I’ve started talking to Lumintop directly, but this ODF30 isn’t one they’d planned on sending.  GearBest sent it out, and here’s my test!  It’s a 26650 light with a Cree XHP70.2 emitter – a category that seems to be getting more interest lately.  Read on!


Official Specs and Features

Versions

There’s only one version of this light!

Price

Looks like the going price of this light is around $70.


Short Review

I like the build of this light.  Some small things like the body, with the alternating big blocks, just make it different enough to be interesting.  The UI is pretty good.  I do wish it came with a cell, and it’s a little large to not also include charging.

Long Review

What’s Included

  • Lumintop ODF30 Flashlight
  • Nylon Pouch
  • Lanyard
  • Spare o-rings (2)
  • Manual and paperwork

Package and Manual

The light ships in a standard Lumintop slip-fid cardboard box.  GearBest puts an inventory sticker on the front, but it doesn’t cover any important info.

Here’s a not-great photo of the manual.  It’s a good manual, including all the needed info, and a UI flowchart.

Build Quality and Disassembly

Nothing is outstanding either good or bad about this light regarding it’s build quality.  It’s good enough, just as it should be.  I’m pleased that the threads on the tailcap are square cut, and [just] adequately lubed, but I found that the cell tube couldn’t be removed from the head.  Could be that it’s threadlocked. (More on that below).
But overall the build is fine.  The head has a good bit of finning, which should help with heat management.

I like the body grip pattern.  Not that it’s strictly useful for grip, but it’s neat.  An alternating pattern of large blocks.  Nice to see something unusual, but that isn’t also immediately horrible.

Here’s the reason I wanted to remove the cell tube.  The o-ring that should waterproof this area looks to be sticking out just the tiniest amount, meaning this light could have questionable waterproofness.  If these parts were separable, I could figure out what was going on, and replace that o-ring with one of the spares.

The bezel unscrews fairly easily, though there are no detents for a spanning tool to grab.  Just press the bezel hard against a soft piece of wood or something and unscrew, and it should give.  The reflector and that interesting red o-ring just come right out.

Size

Officially  120mm x 42mm x 32mm, and 133 without cell.

The ODF30 is approximately in line with the other similar 26650 lights I have.  Seen below is the Thrunite TC20, the ODF30, and the Rofis MR70.  Note that both these other two lights have on-board charging (and the MR70 even serves as a powerbank!) (And they also have similar throw.)

Retention

Lumintop includes a nylon pouch, which will hold the light only in a bezel-up direction.  The pouch is a bit unusual in that it has only one loop which is permanently attached.  You’ll have to thread this one on and off the belt every time (no velcro attachment).

The lanyard attaches on the tailcap, through the small hole seen below.

Power

The ODF30 is powered by a single 26650 cell.  This doesn’t have to be any particular type: flat or button top, protected or unprotected will all work.  It does need to be a capable cell though, because turbo draws over 6A.  So, any good 26650 will work.
Below, observe the runtime on Turbo.  The stepdown is gradual until around 4 minutes, where the light steps to around 2700 lumens (much higher than “High” mode) then steps down a few more times until the light shuts off.

The light claims to have intelligent thermal management, which should kick in around 55 degrees C, but I am not sure this graph corroborates that.  The light decreases output over time, yes, but truly intelligent output thermal management would see the light increasing again to turbo (in my opinion!).
And here is High:

The switch is an indicating switch, so it’ll blink red when the cell voltage gets low.  This happens around 3V.  There’s an earlier warning too – at around 3.2-3.1V, the switch will be solid red.  At around 2.6V, the light shuts off completely.

User Interface and Operation

The ODF30 has a single button.  It’s a side, indicating, e-switch, and has a rounded dome like shape.  I’ve become accustomed to flat buttons, so this one is noteworthy in that regard.  The switch is very clicky and moderately loud.  The actual touch pad for switching seems a bit small for me (maybe it’s the dome giving me this impression).  Anyway, it’s a fine clicky.

Here’s a UI table!

State Action Result
Off Click On (Mode Memory)
Off Hold (~2s) “Eco” mode (Very low)
Off Long Hold (>4s) Lockout*
On Click Mode Advance (LMH)
On Hold Off
On Double Click Turbo
Eco Double Click Strobe
Strobe Click Eco

* Lockout of course starts in Eco, but doesn’t switch off when lockout has been enabled.  Instead, it switches to a slow but bright flashing.  The switch is capable of momentary in this setting. To exit lockout, the tailcap must be unscrewed and tightened.
Something about the switch on mine doesn’t seem quite right.  I’m pretty used to UI’s and switches of all types, and… something just doesn’t always work on this one.  I’m not sure if it’s the switch (likely) or something else electronic that makes things not work exactly correctly.  Overall I can make the light do what it is supposed to do, but there are sometimes when it just seems like the light gets confused and things stop doing what you’d expect.  Most often in these cases, the light just stays in the mode it’s in.

LED and Beam

Lumintop has a Cree XHP70.2 in this light.  It’s a usual choice for this type light, and not a bad one.  The reflector is broad and shallow, and orange peel.  There’s a nice centering gasket around the emitter.

“Eco” isn’t all that low.  It’s fairly low, but not a beam you’d want to look directly into, for example.  I like lower lows than what is offered here.
The beam has a good spot and rolls off pretty smoothly into spill.

Random Comparisons and Competitive Options….

Of course the other two lights in this post are good competitors here.  The Rofis MR70, which adds charging and a powerbank feature, and a side NW emitter is a great offering.  The Thrunite TC20, which has on-board charging as well, is a nice competitor too.  I like the build and the look of the Lumintop, and the indicating switch.  The throw on the Lumintop gets a bit of an edge, I think.

Conclusion

What I like

  • I like the build quality of the light, and the overall look is nice
  • Output hits the rated lumens and throw
  • Indicating side switch

What I don’t like

  • Switch issue caused me to be frustrated with the UI
  • Lacks on-board charging or other features of similar sized lights
  • Doesn’t include a cell (and there are already Lumintop branded cells!)

Up Next

I have a few non-flashlight things to post, just need to do a bunch of writing on them first.  Hopefully I can wrap some of that this week!
