Short Review

The body of this light is as good as any 10180 sized keychain light, but the parasitic drain means this light doesn’t last more than a single day without charging.  I would not recommend to buy this light.  (There are other better options!)

^ 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.

What’s Included

• Lumintop EDC Pico
• Charge cable (USB to micro-USB)
• Keychain connector
• Split ring
• Spare o-rings (2)

Package and Manual

Standard Lumintop package.

Standard Lumintop manual:

Build Quality and Disassembly

The build quality of this light is excellent.  The anodizing makes it easy to grasp and twist, and feels very smooth.  There’s ample knurling on both parts of the body.

It’s sort of…. impossible to photograph adequately, but the head has a sort of “double-threaded” build – Unscrewing the head “all the way” doesn’t immediately reveal the charge port.  The top has to be pulled to reveal the thread, and then may be fully unscrewed, completely off.  It’s a bit unusual, but works fine.  The threads are unanodized.

Size and Comps

Officially 41.5mm x 14mm, and 11.8g.

It’s tiny!  Don’t let that last picture fool you, it’s a twisty (and no momentary, really).

Retention and Carry

There is only the small loop which can accommodate the included split ring, and the keychain connector.  Those things are included.  It could also accept a lanyard, but that isn’t included.

Power and Runtime

Power comes to the EDC Pico by an internal and built-in cell.  The cell is not replaceable, and is charged via micro-USB.  The claim is that the internal cell is an 80mAh 10180.

I performed a runtime test for both modes.  Don’t read much into the squiggly lines – my lux meter just doesn’t like these low modes….  The runtime is unremarkable.  Output is unregulated, and drops to almost nothing within 40 minutes.  There does not appear to be low voltage protection.

The onboard charing claims to be “57 minute fast charge” and that seems to be more or less the case.

The chargetime reveals something interesting, however.  Charging does shut off after around an hour… but in the second test note that charging spins back up 30 minutes after charging.  That’s the parasitic drain.  The parasitic drain is ridiculously high….  10mAh over 30 minutes.  Recall that this cell is only 80mAh?  So 4 hours from a complete charge (roughly speaking), the cell will be dead.

Possibly I just got a bad unit, but who knows really.

Modes and Currents

Mode	Mode Claimed Output (lm)	Claimed Runtime	Measured Lumens	Tailcap Amps
High	130	25	104	0.36
Low	15	4h45m	15	0.02

Pulse Width Modulation

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

The EDC Pico is a twisty.  Twist the head tighter to turn the light to low, and twist the head even tighter for High.  Loosen the head to turn the light off.

LED and Beam

The emitter Lumintop used in this light is an unusual Osram Pusra1.  I don’t have experience with this one, but I’m open to new things.  This new emitter is behind a TIR, which has dimpling, and provides a nice even beam.

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)

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!  I’d recommend any of those lights over this one.  The parasitic drain kills this light.

Conclusion

What I like

• Build quality is good
• On board charging works

What I don’t like

• Parasitic drain makes the light useless
• Don’t love the tint of the Osram emitter.
