Construct High quality and Disassembly
Similar to different lights on this form class by Nitecore, there’s a complete lot to love in regards to the EDC37 Flat EDC flashlight. I’ve reviewed others, just like the Nitecore EDC23 Saber. These are very stable lights! Similar to the EDC27 UHi and EDC23, the Nitecore EDC37 Flat EDC flashlight has a steel physique. The truth is, it’s stainless-steel, and the metal is coated with “titanium-colored PVD.” It’s a pleasant look. Additionally, it feels nice to make use of!
I didn’t disassemble the Nitecore EDC37 Flat EDC flashlight in any respect. It does look to be held along with a lot of TORX screws, although! This one has simply 4 screws per aspect.
The EDC37 options these attention-grabbing screws on the entrance bezel. I suppose they’re tactical (ish) but additionally might be used to reduce burn potential when the sunshine is on and headstanding. Thankfully, Nitecore contains some spare different screws which can be flat
The photograph beneath is meant to indicate that these cooling … holes within the head go all over a part of the physique. I suppose they supply higher cooling, or doubtlessly preserve your gentle elements away from the most well liked elements of this gentle.
Right here’s a little bit of branding on the switch-end of the Nitecore EDC37 Flat EDC flashlight.

If the flashlight can headstand, I’ll present it right here. If it might tailstand, I’ll additionally present that right here!
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 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 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 Whole Tesseract in brass. I like the Trident, and it’s a hanging distinction to the cheap Convoy S2+, one other nice SRM.
Retention and Carry
This pocket clip that ships connected is awfully beefy! It’s so peculiar, the truth is, that I really feel prefer it in all probability matches some position I simply don’t even find out about – prefer it’s utility-built and matches some particular [whatever] [wherever] (like MOLLE attachments do.)
The clip is held in place by two screws – two screws that additionally in all probability maintain elements of the physique collectively.
The included lanyard is paracord with a kind of D-clip which is plastic with a steel gate.
That’s it for included carry choices.
Energy and Runtime
Nitecore says the EDC37 Flat EDC flashlight runs an 8000mAh 28.8Wh battery, however doesn’t say a lot else. It’s not supposed for trade by the consumer. It’s not area serviceable!
I examined the best two modes one of the best ways I may take a look at them. They’re very a lot “momentary” ranges. Not simply that, however as you employ both of these, the ability display screen on the OLED exhibits the ability degree dropping. As soon as it’s expired, the sunshine steps down and 1) cools off and a couple of) energy “recovers.” So in each of those highest-mode exams, I waited till the ability degree had absolutely recovered, then held the swap till energy (adequate for top modes) was depleted. In neither case was the battery absolutely depleted, thoough – it learn 98 and 94% in these modes. However you must have the ability to get the thought.
The temperature traces 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. Temperature sensors are connected nevertheless possible and never at all times on the bezel or hottest spot (assuming that may even be clearly outlined). Even with supreme placement, too many variables have an effect on temperature to definitively state a selected max worth.
Charging
The Nitecore EDC37 Flat EDC flashlight has built-in charging by means of a USB-C charging port within the tail close to the switches. A press-in cowl protects this charging port.
An acceptable cable is included: USB to USB-C. Whereas charging, the OLED shows battery voltage.
Charging is fast! The speed is sort of 2A and in complete takes solely round 2 hours. That’s nice! 
Modes
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens |
|---|---|---|---|
| Lumin Protect (Floodlight) | 8000 | – | 8139 (0s) – (30s) |
| Search (Highlight) | 3000 | – | 2882 (0s) – (30s) |
| Excessive | 1500 | 7h30m | 1357 |
| Mid | 400 | 8h30m | 365 |
| Low | 100 | 30h | 88 |
| Ultralow | 15 | 190h | 10 |
Pulse Width Modulation
There’s a little bit of ripple on a few the decrease modes, and the best degree appears to have what appears like PWM however may additionally simply be larger ripples.
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 put up about it to clarify PWM! Listed below 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 put up additionally explains why I didn’t take a look at the WF-602C on the normal 50us scale.
Consumer Interface and Operation
First, there’s a bodily lockout swap close to the OLED.
With this swap within the locked place (as seen beneath), the OLED responds with “LOCKOUT” however the gentle is not going to output any gentle.
As soon as out of lockout, two switches management the Nitecore EDC37 Flat EDC flashlight. There’s an influence swap – you possibly can see it beneath on the left. The opposite, larger, and flatter swap is a mode swap. Each are e-switches.
The OLED shows fairly a bit of knowledge. It’s a pleasant addition.
Right here’s a consumer interface desk!
| State | Motion | Outcome |
|---|---|---|
| Off | Click on Energy Swap | On (Mode reminiscence) |
| Off | Maintain energy swap (half press) | Momentary Ultralow |
| On | Click on energy swap | Off |
| On | Half press (and maintain) energy swap (if OLED is energetic) | Momentary Ultralow |
| Off | Half press energy swap (if OLED is just not energetic) | Activate OLED show – Continued half presses advance the modes with out the sunshine being on |
| Off | Full press energy swap | On in mode reminiscence or purposefully chosen mode (see steps in earlier row) |
| Unlocked or Lockout 1 | Half press mode swap | Momentary Search (Highlight) |
| Unlocked or Lockout 1 | Full press mode swap | Momentary Lumin Protect (Floodlight) |
| On | Half press (click on motion) energy swap | Mode advance (Lowest 4 modes) |
| Lockout 1 | Energy button | No change in state. OLED will nonetheless show the memorized mode and battery info. |
LED and Beam
The Nitecore EDC37 Flat EDC flashlight makes use of two NiteLab UHi 20 MAX emitters. These emitters look so attention-grabbing!
Regardless of having two emitters (with large footprints), evenly orange peel and small reflectors, this gentle does have a surprisingly tight beam profile.
LED Colour Report (CRI and CCT)
I don’t see wherever that Nitecore makes this declare, however this isn’t a (correctly) cool white flashlight. It’s impartial, with low CRI. The best two modes step down too quick for me to learn the CCT/CRI on these! It’s fairly constant on these 4 examined modes, although, so you possibly can in all probability make correct inferences.
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 (beneath 3000K) is taken into account heat gentle, whereas a better CCT (above 5000K) offers cooler, bluish gentle.
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, just like how they’d look below the solar.
Beamshots
These beamshots at all times have the next settings: f8, ISO100, 0.3s shutter, and guide 5000K publicity. These photographs 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 preserve the take a look at flashlight on the left and the BLF-348 reference flashlight on the appropriate. These photographs 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 perfect tint!
Abstract and Conclusion
These flat-style lights appear very fashionable these days, and the Nitecore EDC37 Flat EDC flashlight is a superb instance. The steel physique is stable, the output is briefly unimaginable, and the decrease modes present a pleasant flat output. USB-C charging works very effectively, and the consumer interface is acquainted and feature-rich. It’s an excellent model of a high-output flat gentle from Nitecore!
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 certain quantity of distinction (say, 10 or 15%) is completely affordable.
What I like
- Sturdy construct – it’s stainless-steel!
- Not simply stainless but additionally coated which in all probability makes it extra sturdy
- Twin swap interface is fairly good
- OLED show appears adequately taken benefit of
- USB-C Charging works nice and is fast
- Output is really outstanding if transient
- Does hit the output claims!
- No proximity sensor
What I don’t like
- Battery is just not replaceable
- Constructive Duv output (inexperienced)
- Low CRI
- “Turbo” modes step down soooo shortly.
