Lumintop has expanded the In Your Pocket (“IYP”) series of lights by two recently. There’s the new IYP25, which is a 2-up AA light, and the IYP07, which is a single AAA light. Today I’m having a look at the IYP07…. a light I’m very excited about!!
Official Specs and Features
There are three body colors (black, pink, silver) and two emitter choices (Nichia 219c, Cree XP-G3). I have the black body, Nichia version.
Price and Coupon
These are going for around $17.95. Get yours on amazon! (That’s a referral link.)
The IYP07 has given me a backup to replace my broken Eagtac D25AAA. It’s nearly small enough to disappear, and it’s nearly bright enough to be useful in most backup situations…. It’s nearly perfect.

* 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).
The specs specify many things for the Nichia version specifically, but I think that throw calculation is likely for the Cree. So don’t expect this to be a thrower with the Nichia, and don’t worry that it’s not hitting spec there.

- Spare o-rings (2)
- Glow diffuser
Package and Manual
Standard Lumintop box. The back has checkboxes for the specifics of the light (body color, emitter).
Good manual, too.
Build Quality and Disassembly
The IYP07 fits perfectly with the other IYP series lights. Good build quality, nice brass adornments, and a very sleek design.
I couldn’t get the driver to budge, despite it having two holes that look to be grippers for screwing… The tail end has a spring.
This little (probably not solid) brass ring comes off fairly easily when the head is removed. That o-ring you can see there helps hold it in place.
The threads are triangle cut, and have very little if any lube. It’s no issue; they’re plenty smooth (and anodized). Mechanical lockout is possible with a very short twist, loosening the head.
There’s a tiny green glow ring in the head.
Size and Comps
Officially 81.5mm long and 14.5mm in diameter, and weighing in at 18.5g. I measure 81.63 and 14.55. Close enough.
Here are a few other AAA lights, including the Eagtac D25AAA, which died on me. I really did like that one, even though it’s a twisty. I understand why the IYP07 is longer, but if it was sized like the D25AAA this would be an absolute must have.
Retention and Carry
The only thing included for carry of this light is a pocket clip. It’s a collar type clip, so very secure. There’s a nice balance with it too. It’s not deep carry, but it’s not that far off. While writing this review I gave another shot at removing the tailcap, and did finally unscrew it. The clip removes very easily, and the light works fine without it there. The gap where it goes, remains, though.
Power and Runtime
I tested the IYP07 with an IKEA AAA cell, the LADDA NiMH AAA. Primary AAA cells will work fine. Lithium ion 10440 cells will not work, and probably will kill the light.
High is very stable, and also hits the claimed specification for the Nichia version very well. Eighty lumens is a little low – I’d love a bit higher top end and maybe on extra mode, but that’s nitpicking. I do appreciate that the output is stable for over 30 minutes, though. (Disregard the bouncing between 75 and 85. That’d my meter being stupid, not the light.)
Medium output is equally stable.
There isn’t LVP, but the light does flash to warn the user that the cell voltage is low. Also the output drops so dramatically it’s impossible to not notice the cell is low voltage.
Modes and Currents
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps|
Pulse Width Modulation
No PWM, yay!
For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. And here’s the worst PWM light I have ever owned. Also one of the very first lights I ordered directly from China!
User Interface and Operation
I wasn’t able to disassemble the switch itself, but if this is like it’s bigger brothers (and I’m pretty sure it is), then this is a mechanical reverse clicky switch. The cap is metal, and very clicky, with around 2mm of travel. Mashing the edges won’t do it – you’ll need to cover the switch to get it actuated.
Note that the switch is big enough and flat enough that the light will tailstand. Fairly well, actually.
Here’s a UI table!
|Off||Click||On (Mode Memory)|
|On||Half Press||Mode advance (HML)*|
The manual mentions strobe in one place, but not in the UI section, and I can’t find a strobe in the light. ¯_(ツ)_/¯
- The manual calls this “Medium Low High” and while I don’t know the difference, I’ll mention that’s how they say it.
The UI is very simple.
LED and Beam
In my review copy, Lumintop has a Nichia 219c. It’s a good temperature, too – warm. Stated as NW but quite warm NW. It’s perfect for this light, and this style light.
There’s a reflector, which has light orange peel.
Sorry about that pic above, not sure what was in focus there. Just rely on the one below, please:
Low is low. Very nice and low. The Nichia claims 1 lumen, and that’s good for a low on a light like this.
The diffuser fits fairly well, but has to be shoved on further than you’d expect. It diffuses diffusely.
These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure.
Tint vs BLF-348 (Killzone 219b version)
Not sure if you’ve thought about it til not, but this light is basically exactly like my tint reference light – single cell AAA light with Nichia. Only it does better – three modes. I should put a 219b in here….
I compare everything to the Killzone 219b BLF-348, because it’s inexpensive and has the best tint!
Random Comparisons and Competitive Options….
Here’s a link to a relevantly filtered page on parametrek.com. I use that site a lot!
Of the competition there are two types: Headlamps, which aren’t really competing with the IYP07. And a Maratac light, which claims Nichia but is probably actually not (and is also probably actually made by Lumintop anyway.) I’d buy the IYP07…. It’s a very great little light, and I’m super happy Lumintop listened to us and made a single AAA version!!
What I like
- Perfect backup, “forget it’s there” light.
- Single AAA
- Nichia option
- Nice build quality
What I don’t like
- No LVP
- This light was provided by Lumintop for review. I was not paid to write this review.
