Lumintop IYP07 Flashlight Review

The Lumintop IYP07 is a fun little flashlight that runs on a single AAA cell and has a nice easy user interface. Reas on!

Official Specs and Features

Here’s a link to the Lumintop IYP07 Flashlight product page.

Versions

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

These are going for around $17.95.  Get yours on amazon!  (That’s a referral link.)

Short Review

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:  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.

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.

What’s Included

• Lumintop IYP07
• Spare o-rings (2)
• Glow diffuser
• Manual

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
High	80	30m	85	0.62
Medium	25	4h	25	0.12
Low	1	40h	–	0.01

Pulse Width Modulation

No PWM, yay!

Here you can see a “baseline” – a chart with almost no light hitting the sensor.

Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.

User Interface and Operation

I wasn’t able to disassemble the switch itself, but if this is like its 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 user interface table!

State	Action	Result
Off	Click	On (Mode Memory)
On	Click	Off
On	Half Press	Mode advance (HML)^

The manual mentions strobe in one place, but not in the user interface 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 user interface 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 a 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 always have the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.

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

Not sure if you’ve thought about it til now, 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!!

Conclusion

What I like

• Perfect backup, “forget it’s there” light.
• Single AAA
• Nichia option
• Nice build quality

What I don’t like

• No LVP
