Cyansky P10 Portable EDC Flashlight Review
The Cyansky P10 is a portable flashlight well-suited for EDC tasks. Small enough for a keychain, it runs a single AA and has a great beam!
Official Specs and Features
Here’s a link to the Cyansky P10 portable EDC flashlight product page.
Only one emitter option exists for the Cyansky P10 portable EDC flashlight, but that emitter is available in three body colors – red, green (seen here), and black.
MSRP for the Cyansky P10 portable EDC flashlight is $24.95. The flashlight is available at cyanskystore.com right now!
The Cyansky P10 is in fact a portable EDC flashlight. It’s nice and small and runs a single AA cell. I like those things about it. I also like the beam profile (nice and tight) and the user interface is very simple. I do not love the green aspect of the beam, which is quite prominent outside of the hotspot. I also wish the P10 would accept a 14500 cell, for more versatility (and maybe higher output). Still, at $25 it’s a good value!

Package and Manual
Build Quality and Disassembly
Build quality of the P10 is great. There’s not a whole lot more to say. It has a great, high-quality feel in hand.
A distinguishing feature of the P10 is this flared head. That does aid grip when removing the head, and doesn’t get in the way of using the P10 (but it still seems a little unusual.)
Threads on the P10 are some of the smoothest I’ve had in a while. Removing the head for cell swaps is a breeze. The threads are anodized and have lube.
The head has only a button, but the tail end (inside the cell tube) has a spring.
Size and Comps
Officially 20.55 mm x 17.5mm x 89.3mm, and 31.5g (without battery or accessories).
If the flashlight will headstand, I’ll show it here (usually the third photo). If the flashlight will tailstand, I’ll also show that (usually in the fourth photo).
Here’s the test light with the venerable Convoy S2+. Mine’s a custom “baked” edition Nichia 219b triple. A very nice 18650 light.
Also above on the left is a new feature light!! Laulima Metal Craft sent this Todai in tumbled aluminum for some size comparison photos like the ones above. Laulima has a bunch of incredible items. I’ve tested one (the Laulima Metal Craft Hoku) (the official site for Hoku is here) that was a Friend Fund Friday review. I was impressed enough by that Hoku that I bought a Laulima Metal Craft Diamond Slim (also in tumbled aluminum) (review is upcoming!) These lights by Laulima have impeccable build quality and not only that, they’re quite configurable. There are some (great, actually) default configurations, but Joshua Dawson (of Laulima Metal Craft) is open to ideas and emitter options and the like. I haven’t reviewed this Todai, but I have to say, it feels absolutely fantastic and I love it thus far. (Notably, I love how warm and eggy those emitters look through the TIR.)
Retention and Carry
A pocket clip is included and attached from the factory on the Cyansky P10. This is a standard two-way clip and has a lanyard hole in the shoulder.
The clip can attach only on the tail end, but because it’s two-way, allows the light to be used on a cap, for example. The clip is a friction-fit variety.
Also included is a simple lanyard, which attaches through the hole in the pocket clip shoulder.
Power and Runtime
The Cyansky P10 portable EDC flashlight runs a single AA cell. It accepts any type of 1.5V cell and includes an alkaline primary AA cell. All my testing was done with the Amazon Basics NiMH rechargeable AA cell seen below. Cyansky offers a different output level for the NiMH cell type – output is a bit higher with those (according to the manual). Runtime should be a good bit longer with primary, though.
The AA cell goes into the P10 in the usual way – positive end toward the head. The tailcap does not come off of the P10.
Here are a couple of runtimes. I can’t really say that the light has LVP, but with only 1.5V cell support, that’s not really a surprise either way. Output drops very low even when the cell is around 1.15V.
Modes and Currents
|Mode||Mode Claimed Output (lm)||Claimed Runtime||Measured Lumens||Tailcap Amps (@1.5V)|
|High||350||2h||265||4.5 (on power supply)|
Pulse Width Modulation
There’s no PWM on any mode, which is great.
For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor. Also, here’s the light with the worst PWM I could find. I’m adding multiple timescales, so it’ll be easier to compare to the test light. Unfortunately, the PWM on this light is so bad that it doesn’t even work with my normal scale, with is 50 microseconds (50us). 10ms. 5ms. 2ms. 1ms. 0.5ms. 0.2ms. In a display faster than 0.2ms or so, the on/off cycle is more than one screen, so it’d just (very incorrectly) look like a flat line. I wrote more about this Ultrafire WF-602C flashlight and explained a little about PWM too.
User Interface and Operation
A single mechanical tail switch controls the Cyansky P10 portable EDC flashlight. The switch is a forward clicky so momentary actuation is possible.
The switch is quite nice, really, and has a very positive feel. In fact, it feels like many tactical switches – good resistance and a specific actuation point.
Here’s a UI table!
|Off||Click||On (Mode Memory)|
|Off||Tap||Mode advance (LMH)|
LED and Beam
Cyansky states on the product page that the emitter here is an Osram P9. I don’t really question that, but I will say that the TIR used here does disguise the emitter quite a bit. There’s a sort of center opening or something – you can see that below. That hole is only through the TIR and not felt on the surface. I would guess there’s a lens over the TIR.
The TIR is of the smooth variety.
This photo doesn’t demonstrate it too greatly, but the TIR above and the emitter used gives a beam profile that I really love. A nice tight hotspot that’s even nearly all the way across. There’s spill too, but not too much.
LED Color Report (CRI and CCT)
These beamshots are always with the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
I keep the test flashlight on the left, and the BLF-348 reference flashlight on the right.
I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!
What I like
- Low cost
- Very simple user interface
- Runs AA cells (ubiquitous)
- Good quality pocket clip
- Great beam profile
What I don’t like
- Green output, particularly outside the center of beam
- Does not run 14500 cell
