Package deal and Guide
Construct High quality and Disassembly
Construct high quality of the Acebeam K1 EDC flashlight is simply effective. Nice, even! This can be a small gentle however has uncommon knurling (or “ridges”) alongside nearly the complete size of the cell tube. So it’s fairly grippy!
The pinnacle has the male threads, which is a bit unusual. Nonetheless, that works simply effective! The pinnacle has two little contact factors. I’m unsure why there are two, however this would possibly forestall flat high cells from working.
Contained in the cell tube (and never pictured) is a spring. It’s not a brilliant heavy spring, nevertheless it’s appropriate for this small gentle.

Right here’s the sunshine in hand:
Right here’s the take a look at gentle with the venerable Convoy S2+. The model beneath is a customized laser-engraved Convoy S2+ host by GadgetConnections.com. I did a full submit on an engraved orange host proper right here! Or go straight to GadgetConnections.com to purchase your Convoy S2+ now!
Additionally within the photograph above, my Normal Reference Materials (SRM) flashlight is the Hanko Machine Works Trident, an 18350 gentle. 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 really like the Trident, and it’s a hanging distinction to the cheap Convoy S2+, one other nice SRM.
Retention and Carry
The Acebeam K1 EDC flashlight incorporates a screw-in pocket clip. Two sides of the Acebeam K1 EDC flashlight are flat, and the pocket clip lives on a kind of flat sides. The clip is lengthy, and there’s a pleasant little bit of flex, nevertheless it’s very appropriate for pocket carry.
A lanyard is included (pictured beneath), and the one great spot to connect it’s by means of the pocket clip.
Energy and Runtime
The Acebeam K1 EDC flashlight features a single lithium-ion cell. It’s a 1000mAh 14500, and is a typical button high.
The cell goes into the Acebeam K1 EDC flashlight within the traditional orientation – optimistic finish towards the pinnacle.
In case you neglect that, you may have a look at this notification on the cell tube.
The Acebeam K1 EDC flashlight will even capably run a single AA cell (NiMH or alkaline). That’s an enormous characteristic!
The temperature strains in these charts are included as normal context, not exact measurements. The values signify the vary (min to max) throughout testing, however shouldn’t be taken as precise readings. A temperature sensor is just not at all times connected to the bezel (and even the most well liked spot, assuming that could possibly be outlined). Even with ideally suited placement, too many variables have an effect on temperature to definitively state a selected max worth.
Charging
Whereas the Acebeam K1 EDC flashlight itself doesn’t have charging, the included 14500 cell does. There’s a USB-C charging port on the optimistic finish.
A brief USB to USB-C cable is included.
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens | Tailcap Amps |
|---|---|---|---|---|
| Excessive | 1000-650-110 | 1m+30m+4.5h | 831 (0s) 776 (30s) |
2.61 |
| Medium | 200 | 2h40m | 174 | 0.29 |
| Low | 9 | 60 | 9 | [low] |
| Laser | – | – | – | 0.03 |
| UV – Excessive | – | 3m+120m | – | 0.84 |
| UV – Low | – | 180m | – | 0.21 |
Pulse Width Modulation
The bottom LED mode has a little bit of sawtooth, however not PWM. The opposite two modes are very regular.
Click on right here to see a “baseline” – a chart with nearly no gentle hitting the sensor.
Then there’s the Ultrafire WF-602C flashlight, which has among the worst PWM I’ve seen. It’s so unhealthy that I used a submit about it to clarify PWM! Listed here are a number of timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make evaluating this “worst” PWM gentle to the take a look at gentle simpler. That submit additionally explains why I didn’t take a look at the WF-602C on the traditional 50us scale.
Person Interface and Operation
The Acebeam K1 EDC flashlight is managed by a single mechanical tail swap.
The swap is proud however flat and doubtless metallic, so it could possibly tailstand (principally).
Motion may be very deep and optimistic.
The output choice is made with a rotating ring across the head. It selects LED, Laser, and UV (in that order).
Right here’s a consumer interface desk! Usually, I’d say have the rotary within the place you need earlier than turning on the sunshine, however that’s not likely required. You possibly can rotate whereas the sunshine is on, and it’ll nonetheless work effective.
| State | Motion | Consequence |
|---|---|---|
| Off | Click on | On (low, usually) |
| On | Click on | Off |
| Off | Repeated faucets | LED output advance (LMH) or UV advance (Low > Excessive) |
| LED on | Rotate to the laser, then again to the LED rapidly | LED Strobe |
LED and Beam
Acebeam calls this a Cree XP-LR emitter and states it’s 6500K. The emitter has a clean reflector.
UV has a tiny reflector, too.
The white LED is pretty throwy, or not less than has a pleasant tight beam profile.
The laser on this Acebeam K1 EDC flashlight doesn’t have any modes, nevertheless it’s fairly highly effective, as a “3R” laser.
I just like the bezel, too!
LED Coloration Report (CRI and CCT)
Acebeam claims 6500K for the white LED output, and I measure it as “a bit higher” than that – when you contemplate much less cool white higher. The CCT ranges from round 6000K to round 6500K with a low CRI throughout the board.
CCT (Correlated Coloration Temperature) refers back to the measurement of the colour look of sunshine, expressed in Kelvins (Ok), which signifies whether or not the sunshine is heat (yellowish) or cool (bluish). A decrease CCT (beneath 3000K) is taken into account heat gentle, whereas the next CCT (above 5000K) offers cooler, bluish gentle.
CRI (Coloration Rendering Index) is a measure of how precisely a lightweight 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 underneath the solar.
Beamshots
These beamshots at all times have the next settings: f8, ISO100, 0.3s shutter, and guide 5000K publicity. These images are taken at flooring stage, and the beam hits the ceiling round 9 ft away.
Tint vs BLF-348 (KillzoneFlashlights.com 219b model) (affiliate hyperlink)
I hold the take a look at flashlight on the left and the BLF-348 reference flashlight on the fitting. These images are taken round 18 inches from the door.
I evaluate every little thing to the KillzoneFlashlights.com 219b BLF-348 as a result of it’s cheap and has the very best tint!
Abstract and Conclusion
The Acebeam K1 EDC flashlight is a neat little gentle and has a bunch of enjoyable options. I don’t love UV (as traditional), nevertheless it’s simple sufficient to keep away from on the K1 (simply by no means rotate the rotary to that place). The consumer interface is straightforward for the white LED, and strobe is appropriately tucked out of the way in which. I really like that the Acebeam K1 EDC flashlight can use each the included 14500 and an AA cell
The Huge Desk
^ Measurement disclaimer: Testing flashlights is my passion. I exploit hobbyist-level tools for testing, together with some I made myself. Attempt 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
- Makes use of each 14500 and AA cells
- Normal 14500 included
- Easy consumer interface
- Helpful laser
What I don’t like
- Would love a 4th white LED mode
- Cool white and low CRI
