JetBeam E40R EDC Flashlight Review (Finito!)

Jetbeam E40R Review

!DSC_6287!

Hey folks its been a few months since my last written review. Christmas was a busy period. So over the next few weeks I have a few reviews to post up!

I have EDC this light for over a week and think this may be my first proper 18650 EDC. I would carry the E40R as an EDC.

I was contacted by Gearbest and they offered some lights and I chose the Jetbeam E40R. Any one who is regular knows how much I like Jetbeam so prepare your self for some favoritism. We do not hear much about Jetbeam any more but they still make some great lights. I like the design of the newer Jetbeam lights they stand out.

Purchase link
Price: 36.99 USD

What is included? (Everything you need)

  • Jetbeam E40R
  • Jetbeam JL26 18650 cell
  • Holster
  • Lanyard
  • Clip
  • USB cable
  • Clip
  • Spare O-rings
  • User manual/ Warranty Card

!DSC_6253!

Build
As usual Jetbeam has come thru with a winner in the E40R. The E40R is built to the highest quality standards. Every thing on the E40R is good all the machining looks perfect and the threads are all perfect. The lens is clean and no marks are to be found any where on this light. No defects in the E40R what so ever!

!DSC_6318!

The E40R is one of the smallest 18650 flashlights on the market. It is smaller than most common flashlights like the Convoy S2+ and BLF A6. The Jetbeam E40R is on par with many 18650 headlamps coming in only a few millimeters bigger than the HC30 and H03. It must be noted that the E40R does include USB charging while these headlamps do not. The E40R is actually smaller than some 14500 flashlights i own.

!DSC_6322!

Size

  • Length: 106.25mm
  • Head diameter: 26.7mm
  • Tail diameter: 25mm
  • weight 67.2g without the battery
    The overall Size of the E40R is amazing. The E40R would have to be one of the smallest and lightest brand name high output 18650 flashlights on the market.

!DSC_6327!

The E40R has all the usual bells and whistles that you would find on a high end flashlight. Plus extra!

  • AR coated glass double sided
  • Hard anodizing type 3
  • Coated metal reflector (Op style)
  • Aero grade aluminum alloy
  • Anti abrasive Grey finish (anodizing)
  • USB charging

!DSC_6285!

*Design *
I guess design and build fit closely together they could even be the same category. Design wise the E40R is amazing Jetbeam seem to be coming up with different looking flashlights all the time. I like the finish on the E40R the gray anodizing looks awesome. The anodizing on the E40R is a similar color to the Jet MK1 and 2 but the anodizing does looks a little darker on the E40R. This could be because of the lighting conditions.

!DSC_6298!

I can guarantee you that this anodizing is very hard wearing. I did EDC both the jet MK 1 and 2 and they still look new. That is how good the anodizing is on these jetbeam flashlights. I never take care of my EDC flashlight as they are meant to be used and abused.

!DSC_6337!

The side switch on the E40R is a bare metal color with an LED light that activates when charging a cell inside the E40R.
The side switch on the E40R sits flush with the body. You will not have any issues with accidental activation on the E40R. Plus there is a slight delay when turning on the E40R to help eliminate accidental activation. This feature can be a tad annoying but I can see why they done it. There is a way to bypass this any way.

!DSC_6336!

I think any EDC style flashlight can use a lockout but there is no option for lockout on the E40R unless you undo the tail cap.

Not only is the E40R a good looking light it has the specs and features to back up its good looks. Drop resistance is a bit average but seeing as the E40R can run on 2 CR123s it will be using a buck driver which are a bit fragile.

Durability specs

  • IPX8
  • 1m drop resistant
  • 2m water resistant

Performance
What can I say?
The E40R performs very very well. I mean class leading performance? The E40R uses a Luminus SST40. Just to change it up from the usual Cree LEDs.
The use of the Luminus SST40 is what sets the E40R apart from other flashlight in this category. The SST40 is a performance monster stock running at 5amps this LED is capable of putting out 1800 lumens (using the top bin LED).

!DSC_6347!

This performance comes from a single die LED these output figures are ones we would see only from a worked XPL or stock XHP35.
Output wise Jetbeam rate the E40R at 1150 lumens . I am honestly not sure why Jetbeam didn’t use the standard current of 5amps or are claiming they dont?. I can say my output figures are different from the Jetbeam output numbers the E40R is super bright. Its probably just the stock cell holding the E40R back from its full potential.

Luminus SST40 (Looks similiar to a XML2)
!DSC_6312!

The E40R uses a single 18650 which is included with the light. The stock cell is fairly average it is the JL26 (2600mah) cell that came with there headlamp years ago. Jetbeam state they achieve there output numbers with a different cell the 3500mah. I will be using either a Samsung 25r or a Sony VTC5.
Jetbeam also say performance will vary depending on what cell is used. Which gives us hope that a high drain cell will increase performance.

The E40R is using an OP style reflector or what Jetbeam calls a Coated metal reflector. The reflector is designed by Digital optical system I did Google them and found no info on them. The beam pattern is nice its very even and has no rings. The beam is wide but still offers good throw for such a small reflector.

!DSC_6233!

Throw specs

  • 195 meters
  • 9600cd

The SST40 in the E40R is cold white as you would expect. Even more so because luminus is not yet selling other variants. By looking at the light output its hard to tell that it is cold white it almost matches Crees NW tint. So the LED comes of as being a NW emitter even though it is cold white.
The SST40 has more of a green tint which I like it gives it a warmer feeling. Al thought is it only CRI70 I think you will be surprised by the tint.
Its a bit hard to explain so I will leave some beam shots here so you can see for your self.

E40R left (SST40) and SP32 Right (Cree XPL2)
!Sp32!

The Jeatbeam E40R also has a memory function it will remember last used mode.

Output and modes

  • High: 1150 lumems at 2H
  • Medium: 310 lumens at 4.5h
  • Low: 35 lumens at 50h
  • Ultralow: 3 lumens at 270h
  • Strobe: 1150 lumens

!DSC_6226!

My tested output on high mode is higher than Jetbeams this could be for a few reason. First I could be completely wrong but I doubt I am completely wrong maybe a bit off but not out right wrong. Also the fact that Jetbeam tests with a standard cell a re-badge Panasonic NCR18650. At the same time I retested my BLF A6 and got a usual number just to be sure.

Jetbeam E40R Real Output

  • High mode: 1430 lumens

Not a bad effort by the E40R it holds its own. This is the number I would expect once we take away light loss from the reflector and lens. Seeing as I measured the driver at 5amps it would equate to around 1600 LED lumens.

!DSC_6222!

Mode spacing is okay I do not like the massive gap between high and medium I could see a 600-700 lumens mode being handy. Technically speaking there is a 700 lumens mode that autocratically activates after 3 minutes of the E40R being on high mode. So that is a bonus.

Current readings (Samsung 25r)

  • Standby current: 55 milliamps
  • High mode: 5+ amps

!DSC_6317!

Driver features

  • High efficiency Constant Current driver
  • Temperature regulation
  • USB charging
  • Reverse polarity protection
  • Low battery protection
  • Memory function

!DSC_6295!

UI
The UI on the Jetbeam E40R is super simple. Its a simple push and hold to turn on and than you push the side switch to changes modes. The E40R does have a quirk of taking 3 seconds to turn on from off. Its different I can say that!
Not such an issue unless it was an emergency situation? If you double tap from off the light will turn on in strobe mode straight away with no delay this may help If you are in an emergency. I guess I can see why Jetbeam done this its kind of a lockout so you do not accidentally activate the E40R but on the other hand its a tad annoying. Well at least for me because I am impatient.
I can not see any instant access to Ultra low or high from from off unless its saved by the memory. As I said a super simple UI.

!DSC_6292!

The E40R has 5 modes as listed below

  • Ultra Low
  • Low
  • Medium
  • High
  • Strobe

!DSC_6276!

Thermal regulation
When running the Jetbeam E40R in high mode the flashlight will be become hot. Actually extremely hot lol! I have a new laser thermometer lets try it.

E40R temperature test in Celsius
Room Temp: 26c

  • 30 seconds: 42c
  • 60 sec: 48c
  • 90 secs: 55c
  • 120 sec: 58c
  • 150 sec: 60c
  • 180 sec: 65c

!DSC_6248!

Its actually not as hot as I thought it would be I would have guessed around 60 degrees Celsius after 1 minute.
Any way the E40R does have thermal management. The E40R will step down from high mode to a secondary high of sort which is 65% of total output after 3 minutes of operation. Why not just use medium mode?

!DSC_6282!

USB charger
The Jetbeam E40R does have inbuilt USB charging it uses a standard micro USB cable and has an input of 5v @ 1amp. The E40R charges a standard 18650 at 750mah. It should take around 4 hours for a standard cell to be fully charged. The E40R side switch does blink green when charging. The side switch changes to constant green when the charge cycle is complete. I did notice the green light change a bit early before charge cycle was complete when I checked the cell it was at 4.10v. If left on a bit longer after the light turns straight green the battery voltages at 4.21v so perfect.

!DSC_6331!

Overall the Jetbeam E40R is an awesome light. Defiantly worth the buy! The build quality is top notch and second to none and the output is more than respectable. The push and hold to turn on is a bit annoying I hate waiting 3 seconds but if you can looks past its flaws the E40R is a great buy.

Thanks for the review!

I have a E40R and really like the design, how compact it is, the modes (a nice low moon mode), and the beam. I changed the SST40 to a warm 90CRI XM-L2 but that is just because I can’t like cool light, the tint of the SST40 is pretty good.

But those 3 seconds to switch it on and off…… Tired

Too bad, the light has a very nice looking form factor. But the UI and the green tint would bother me.

That was a really thorough review! Nice light, but the 3 second push for on and off is a deal-breaker for sure.

Yeah, what is it with JB and green tints??

My Jet-Is and Jet-II all have rather nauseating green beams. ‘Swhy I relegate them to “emergency only” lights, ‘cause it’d drive me buggy to keep looking at a green beam.

Really great lights otherwise, but damn that green…

Nice review EDSG.

I like the style of most Jetbeam, and the UI of my Jet II Pro’s.
My gripe, and I know I can not be the first to mention this, they need to make the pocket clips universal for both directions. It would be real nice if I could clip to the bill of my hat!!

Did you do an output test? Its fairly bright how does it perform with the XML?

I like the tint on the SST40 i would say its more appealing than the cold whites from Cree? This would be a 6000k+ tint.
The tint would be on side of a Nichia tint. But it is only 70CRI.

I bought 4 of these SST40 from Kaidomain i will dedome 2 and put them in semi throwers the others i want mega output from. I am yet to check if the tint if the same on my SST40 compared to the E40R.

The XPG2 in the Jet MK1 is a bit blue i think that is all CW XPG2s when they are under driven not helped by the SMO reflector.

Yea i would love a resealable clip but they are few and far between on lights. Then i can wear it on hat makes it extra handy!

I never measured the output stock, but on the XM-L2 3000K 90CRI it puts out 725 lumen @ 30 seconds.

so i got this one…iam fallin in love into this smallies:)
but,the rubber of usb cover is even opened,when i try to remove the torch from trousers…but this is ok.
The modes selection-the start with turbo is not good…and the on/off waiting is really almost 3 seconds…..this is the dealbreaker for many…its my new toy and iam ok with it…Finally something original..Its very sexy and compact…But the waiting time is bad..Shortcut to strobo and then to normal mode is very heplfull but….Yes,its annoying…But its very nice flashlight.Anyway SST40 is not for everyone…Too COLD/GREEN.
