Bundle and Handbook
Construct High quality and Disassembly
The Cyansky Ark II EDC flat flashlight is one other flat mild! Possibly the primary one by Cyansky, and it gives some good diversions from the opposite flat lights available on the market. I’ll point out most of these later, however to summarise: no Laser, no UV. However a lot of white LED!
The construct high quality is sweet, however the mild will not be supposed to be disassembled. There are a few screws (TORX) on the tail, however you wouldn’t use these to swap a battery within the area.
Dimension and Comps
4.41″D x 0.67″W x 1.06″H, 16oz.
If the flashlight can headstand, I’ll present it right here. If it could possibly tailstand, I’ll additionally present that right here!
Right here’s the check mild with the venerable Convoy S2+. The model under is a customized laser-engraved Convoy S2+ host by GadgetConnections.com. I did a full put up on an engraved orange host proper right here! Or go straight to GadgetConnections.com to purchase your Convoy S2+ now!
Additionally within the picture above, my Normal Reference Materials (SRM) flashlight is the Hanko Machine Works Trident, an 18350 mild. Whereas I’ve not reviewed or examined the Gunner Grip model seen right here, I’ve examined a Hanko Machine Works Trident Complete Tesseract in brass. I like the Trident, and it’s a putting distinction to the cheap Convoy S2+, one other nice SRM.
Retention and Carry
The Cyansky Ark II EDC flat flashlight has a two-scre pocket clip alongside the COB aspect (aka the “again”). I fairly just like the clip.
It’s correctly deep carry, however the screws and clip do sit off the sunshine physique only a bit.
Within the tailcap there’s a magnet, which is sufficiently robust for holding the Cyansky Ark II EDC flat flashlight.
Energy and Runtime
The Cyansky Ark II EDC flat flashlight runs on a built-in 1000mAh LiPO battery. I can’t say something extra about it than that; the battery isn’t accessible in any respect.
Beneath you may see a bunch of runtimes – principally the best modes, however for all of the white LED choices. That’s a bunch of runtime assessments.
The Cyansky Ark II EDC flat flashlight does shut off, in a approach that appears to be low voltage safety. It additionally has 4 indicator LEDs beneath the rotary controller. You may see these under (three inexperienced, one unlit.)
The temperature strains in these charts are included as normal context, not exact measurements. The values characterize the vary (min to max) throughout testing, however shouldn’t be taken as actual readings. Temperature sensors are hooked up nevertheless possible and never all the time on the bezel or hottest spot (assuming that may even be clearly outlined). Even with splendid placement, too many variables have an effect on temperature to definitively state a particular max worth.
Charging
USB-C is used for charging the Cyansky Ark II EDC flat flashlight. There’s a press-in silicone cowl. It’s ample, and I’ve no complaints about it.
The charging port does appear to have only a little bit of wiggle contained in the physique. It really works superb, however I might not abuse it.
A USB to USB-C charging cable is included.
Each A to C and C to C work superb and have very related profiles. Charging is form of sluggish, at round 0.5A, and takes nearly 3 hours.
Whereas charging, the 4 indicator LEDs beneath the rotary blink because the cost will increase. When charging is full, all 4 LEDs are stable inexperienced.
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens |
|---|---|---|---|
| Turbo – Each | 1500 | 10s+2.5h | 1825 (0s) 196 (30s) |

Pulse Width Modulation
Nearly each mode of the Cyansky Ark II EDC flat flashlight makes use of PWM. Simply turbo (high row, rightmost) for “each” (the one precise turbo mode), and the best COB white (4th row, third column) and regular COB pink (4th row, 4th column) don’t use PWM.
Click on right here to see a “baseline” – a chart with nearly no mild hitting the sensor.
Then there’s the Ultrafire WF-602C flashlight, which has a number of the worst PWM I’ve seen. It’s so dangerous that I used a put up about it to elucidate PWM! Listed here are a number of timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make evaluating this “worst” PWM mild to the check mild simpler. That put up additionally explains why I didn’t check the WF-602C on the standard 50us scale.
Person Interface and Operation
The Cyansky Ark II EDC flat flashlight has a rotary management and an e-switch. The rotary has very aggressive edges, and far to my shock, I fairly like this. It’s potential to show this rotary from the aspect (as seen under) with the rotary in any place. As a result of there are bumpouts on the highest (corresponding to the place the lock icon is), it’s additionally potential to show this from the highest aspect, too. It’s fairly good.
The rotary management order is a bit uncommon, although. With the rotary in COB place, the order is as follows (twisting within the clockwise course). COB, each entrance, lock, spot entrance, flood entrance. I suppose having lock within the center is the only option, even when we’re used to it being off on one aspect or the opposite.
After making your output choice, you may change the modes of that output with the e-switch.
Right here’s a person interface desk! The person interface is essentially the identical for every rotary choice, however some alternatives have fewer modes. One factor that I feel the handbook actually fails at is describing turbo. There’s just one turbo – that’s the best output for each entrance emitters. Within the desk, it seems to be like spot and flood entrance emitters each have a fifth mode. They don’t. They every have solely 4 modes. (That’s not an issue, however the desk ought to be clearer.)
| State | Motion | End result |
|---|---|---|
| Lock | Any motion on e-switch | Each entrance LEDs and inexperienced indicator LEDs blink to point lockout |
| Rotary in any place apart from lock, in any state | Double click on | Turbo |
| On | Click on | Off |
| On | Maintain | Mode advance for chosen output (excludes ECO, even on COB white) |
| Off | Maintain | ECO mode for chosen output |
| Off | Click on | On – mode reminiscence |
LED and Beam
Cyansky doesn’t say that the emitters are. The flood emitter (left under) has an fascinating design on the TIR. This most likely aids in dispersing the output. The throw emitter (proper) has an optic designed for throw.
Right here you may see the COB output in white and pink.
LED Colour Report (CRI and CCT)
Output is cool white. CRI is low.
Solely the aspect white COB isn’t cool white. Sadly, it’s low CRI like the opposite white outputs.
CCT (Correlated Colour Temperature) refers back to the measurement of the colour look of sunshine, expressed in Kelvins (Okay), which signifies whether or not the sunshine is heat (yellowish) or cool (bluish). A decrease CCT (under 3000K) is taken into account heat mild, whereas a better CCT (above 5000K) provides cooler, bluish mild.
CRI (Colour Rendering Index) is a measure of how precisely a light-weight supply renders colours compared to pure daylight. Scored on a scale from 0 to 100, greater CRI values point out that colours seem extra true to life and vibrant, much like how they’d look beneath the solar.
Beamshots
These beamshots all the time have the next settings: f8, ISO100, 0.3s shutter, and handbook 5000K publicity. These pictures are taken at ground degree, and the beam hits the ceiling round 9 toes away.
Tint vs BLF-348 (KillzoneFlashlights.com 219b model) (affiliate hyperlink)
I maintain the check flashlight on the left and the BLF-348 reference flashlight on the precise. These pictures are taken round 18 inches from the door.
I examine the whole lot to the KillzoneFlashlights.com 219b BLF-348 as a result of it’s cheap and has the very best tint!
Abstract and Conclusion
I do know flat lights are standard, and it’s good to see Cyansky get within the recreation with the Cyansky Ark II EDC flat flashlight. It’s possible the least expensive flat flashlight obtainable on this dimension, in order that’s nice. I additionally like that it doesn’t have a laser, and I like that it doesn’t have UV. These are each wins for me. Charging may very well be a superb bit sooner (1A can be affordable), and I dislike how dramatic and fast the stepdowns are. For $35, the construct high quality makes the sunshine value contemplating. Possibly it might be potential to place a greater collection of emitters within the entrance slots!

^ Measurement disclaimer: Testing flashlights is my pastime. I take advantage of hobbyist-level gear for testing, together with some I made myself. Strive to not get buried within the particulars of producer specs versus measurements recorded right here; A specific amount of distinction (say, 10 or 15%) is completely affordable.
What I like
- Low price
- No UV
- No Laser
- Aggressive rotary management edges
What I don’t like
- Dramatic stepdown on turbo
- Excessive CCT
- Low CRI
