Package deal and Guide
Construct High quality and Disassembly
The JETBeam E28 EDC Multi-mode Flat Tactical flashlight has a high quality construct high quality. It has a construct design very like another current fashions. One instance is the LoopGear SK-05 Professional – the format is a bit completely different, however they’re very comparable lights.
One nice characteristic is that the cell might be swapped. The tail finish opens and there’s a locking mechanism too (so it received’t by chance open.)
The tailcap has twin springs.
The top has simply buttons for contact with the optimistic ends of every cell.

Right here’s the sunshine in hand:
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 hanging distinction to the cheap Convoy S2+, one other nice SRM.
Retention and Carry
There’s a pocket clip included right here, but it surely’s not hooked up by default. It simply requires two screws, and an additional is included. A TORX driver can also be included!
The included lanyard might be hooked up via this gap on the hinge facet of the tailcap.
It’s a quite simple lanyard.
The tailcap additionally has magnets which might be sturdy sufficient to carry the sunshine in place.
Energy and Runtime
The JETBeam E28 EDC Multi-mode Flat Tactical flashlight makes use of two 18650 cells. The 2 which might be included are 3500mAh normal 18650 cells.
Each cells go into the sunshine with the button (optimistic finish) towards the pinnacle. They’re parallel, too, so that they each go in the identical path. This does imply that the sunshine can run with only one cell!
Runtime assessments are under. I examined the upper two modes with each kinds of output (spot and flood). I didn’t check the output with each emitters, although. I don’t consider the guide makes any declare about that output stage. (That is precisely the identical state of affairs because the LoopGear SK-05 Professional, truly!)
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 isn’t all the time hooked up to the bezel (and even the most popular spot, assuming that could possibly be outlined). Even with preferrred placement, too many variables have an effect on temperature to definitively state a particular max worth.
The sunshine shuts off with low voltage safety. There’s a distinguished facet RGB COB that alerts the person to the approximate cell voltage at startup. The colours point out as follows:
Inexperienced: 100-35%
Orange: 34-10%
Pink: <10%
Pink flashing: <5%
Charging
UBS-C charging is used for the JETBeam E28 EDC Multi-mode Flat Tactical flashlight. The port is close to the pinnacle and has a press-in silicone cowl.
A C to C charging cable is included.
Charging works simply high quality from each C to C and A to C. There’s a bit of blip within the purple graph line – that’s simply the place I knocked the sunshine off my desk. (oops). However charging works simply high quality! (Right here’s one distinction on this mild and the SK-05 Professional, although – this one appears to all the time cost at 5V!)
Powerbank
The guide states that the JETBeam E28 EDC Multi-mode Flat Tactical flashlight can be utilized for discharging at 5V/3A. I didn’t check that, however doubtless will.

Pulse Width Modulation
Not one of the regular modes make the most of PWM.
Click on right here to see a “baseline” – a chart with virtually 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 clarify PWM! Listed below 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 normal 50us scale.
Person Interface and Operation
There are two methods to work together with the JETBeam E28 EDC Multi-mode Flat Tactical flashlight. First, there’s a rotary dial. It has 4 positions. Locked, flood, spot, and facet (or “different” possibility, actually, as a result of this covers RGB, UV, and Laser features).
Subsequent is the e-switch, which is on the facet of the JETBeam E28 EDC Multi-mode Flat Tactical flashlight.
The setup is completely different than that of the LoopGear SK-05 Professional, however the features are very a lot comparable.
As acknowledged above, there’s a rotary dial with 4 positions. You’ll wish to rotate this dial to your output of alternative, then observe the actions within the person interface desk under! Be aware that the person interface for Spot and Flood appears to be the identical.

LED and Beam
There are two choices right here for output. Within the picture under, the left emitter is the flood output. That is an unidentified 5000K emitter. The opposite emitter is a Luminus SFT42R and has a easy reflector.
LED Colour Report (CRI and CCT)
I don’t see the data wherever on my bundle, however this flood emitter seems to be the 5000K model (surprisingly!). And it measures very a lot in that vary, too, which is nice! The spot emitter is cool white, however doesn’t recover from 6100K (one other nice shock). Each emitters are low to very low CRI.
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 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 beneath the solar.
Beamshots
These beamshots all the time 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 toes away.
That third row picture is each emitters.
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 images are taken round 18 inches from the door.
The third row right here is the laser output.
I evaluate all the pieces to the KillzoneFlashlights.com 219b BLF-348 as a result of it’s cheap and has the very best tint!
Abstract and Conclusion
I just like the JETBeam E28 EDC Multi-mode Flat Tactical flashlight almost as a lot as I’ve favored any of those flat side-by-side 18650 lights. This one has so many options. Laser is a pleasant bonus right here. I’d like an adjustable CCT facet white output, however that’s not truly the most important deal. I’m more than happy that this primary iteration from JETBeam does have (simply!) detachable and normal 18650 cells. Actually, it could possibly be acknowledged higher – these cells are field-swappable, which is a really good characteristic. (And it could actually even run on only one in a pinch!) The worth of $136 is certainly a problem, however no less than JETBeam is a good model.

^ Measurement disclaimer: Testing flashlights is my passion. 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 cheap.
What I like
- Strong construct high quality
- Cells are simply accessible (aka “supposed for entry”)
- Makes use of normal 18650 cells
- Intuitive person interface
- RGB facet choices are enjoyable!
- C to C charging works properly
- Can run off only one cell
- Presents 5000K within the flood channel
