Package deal and Handbook
Construct High quality and Disassembly
I’m not going to belabor the textual content of this assessment. It is a $24 gentle – please test the testing for the most particulars!
The Sofirn ST1 rechargeable flat EDC flashlight is just not capable of be disassembled in any respect. All components are press-fit from one finish or the opposite
It is a very modern gentle! There isn’t any pocket clip and nothing in any respect to catch or snag. It’s fairly distinctive in that.
Measurement and Comps
Measurement: 28 × 16 × 120 mm
Weight: 100g (3.53 oz) together with built-in battery
Right here’s the sunshine in hand:
Right here’s the check 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 placing distinction to the cheap Convoy S2+, one other nice SRM.
Under you may see the Sofirn ST1 rechargeable flat EDC flashlight with an Olight ArkPro.
Retention and Carry
The one technique of carry for the Sofirn ST1 rechargeable flat EDC flashlight is an included lanyard. It’s a really minimal lanyard!
Notably, there’s no magnet (anyplace) on the sunshine. Particularly within the tail, for the reason that tail is the place there’s a USB-C charging port!
Energy and Runtime
The Sofirn ST1 rechargeable flat EDC flashlight has a built-in battery, and Sofirn says it’s 2100mAh.
The battery is just not discipline replaceable, and is admittedly not serviceable in any respect.
Under you may see the runtime exams on the three highest modes.
There’s an indicator characteristic across the change that may let you understand when cell voltage will get low.
The temperature strains in these charts are included as basic 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 all the time connected to the bezel (and even the most popular spot, assuming that may very well be outlined). Even with superb placement, too many variables have an effect on temperature to definitively state a particular max worth.
Charging
The Sofirn ST1 rechargeable flat EDC flashlight gives a USB-C charging port within the tail. There’s a press-in cowl. It’s actually quite simple, however I like that the sunshine doesn’t have a charging port on the aspect – one much less factor to snag!
Sofirn features a quick C to C cable.
Charging by way of C to C works nice and takes simply over 2 hours. A to C works too (however I appear to have misplaced the logged information for that check!)
When charging, the indicator across the e-switch is purple. When charging is full, the indicator turns inexperienced.
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens |
|---|---|---|---|
| Turbo | 1500-600 | 2m+100m | 1226 (0s) 1148 (30s) |
| Excessive | 800-600 | 10m+100m | 610 (0s) 601 (30s) |
| Medium | 350 | 3h30m | 277 |
| Low | 10 | 100h | 8.5 |
| Moon | 1 | 450h | 0.34 |
Pulse Width Modulation
Each mode makes use of PWM.
Click on right here to see a “baseline” – a chart with virtually no gentle hitting the sensor.
Then there’s the Ultrafire WF-602C flashlight, which has a few of the worst PWM I’ve seen. It’s so dangerous that I used a submit 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 gentle to the check gentle simpler. That submit additionally explains why I didn’t check the WF-602C on the regular 50us scale.
Consumer Interface and Operation
The Sofirn ST1 rechargeable flat EDC flashlight makes use of an e-switch close to the top for operation. As you may see beneath, there’s a sign characteristic across the change.
The change is somewhat proud, however not problematically so. It’s sufficient proud, although, that when you relaxation the sunshine on a flat floor and press the change towards that floor, the change will be actuated. So perhaps it’s a good suggestion to lock the sunshine out electronically.
Right here’s a consumer interface desk!
| State | Motion | Consequence |
|---|---|---|
| Off | Click on | On (Reminiscence) |
| On (Besides Turbo) | Click on | Off |
| On | Maintain | Mode advance (L>M>H) |
| Off | Maintain | Moonlight |
| On | Double click on | Turbo |
| Turbo | Double click on | No change in state |
| Turbo | Click on | Earlier mode |
| Lockout | Maintain | Momentary Low |
| Lockout | Click on | Change battery indicator |
Technically, this isn’t an actual customary Sofirn e-switch consumer interface, nevertheless it’s shut sufficient that you just’re unlikely to have issues with it. Notably, there are no strobes on the Sofirn ST1 rechargeable flat EDC flashlight.
LED and Beam
Sofirn says these emitters are SFT25R 3V 6000-6500K *1, CSP1313 5000K *4. They will’t be operated independently, which is a little bit of a shock. And there’s no secondary (like purple, UV, or laser).
Under you may see it – all emitters on without delay.
LED Colour Report (CRI and CCT)
The mix of assorted CCT emitters brings this gentle into impartial at first, however by the upper modes, it’s cool to very cool white. CRI is low throughout the board.
CCT (Correlated Colour 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) provides cooler, bluish gentle.
CRI (Colour 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, increased CRI values point out that colours seem extra true to life and vibrant, just like how they might look underneath 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 stage, and the beam hits the ceiling round 9 toes away.
It’s fascinating that the bizarre emitter array doesn’t actually change the beam profile from a normal circle.
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 correct. These pictures are taken round 18 inches from the door.
I evaluate every thing to the KillzoneFlashlights.com 219b BLF-348 as a result of it’s cheap and has the most effective tint!
Abstract and Conclusion
The Sofirn ST1 rechargeable flat EDC flashlight may be very good for what it doesn’t deliver to the desk: confusion, strobe, further options, and better value. That’s refreshing, actually, and price taking a look at (as a present gentle, if nothing else)! At $24, this can be a sensible choice for somebody who desires a flat gentle however doesn’t want strobe, ramping, secondary emitters, or UV or a laser, and can possible carry this in a bag.
The Huge Desk
^ Measurement disclaimer: Testing flashlights is my interest. I exploit 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 cheap.
What I like
- Low value
- Sparse options
- Beam profile
- C to C charging
- No pocket clip or screws (once more, carrying on the sparse theme)
- No strobe
What I don’t like
- Very cool CCT on the best modes
- Consumer interface is somewhat uncommon (double click on lockout)
- Battery not replaceable
