POST #15: Beamshots and Comparison

Hi BLF! This is the review of the Wuben E10 flashlight.

The flashlight was sent by Wuben for review, with no other compensation than keeping the flashlight and accessories. Thanks Jelina for sending the flashlight!

Despite this, I will do my honest and critical review on this light!

You can find information about this flashlight here: http://www.wubenlight.com/product/1040

There are also some video and written reviews here:

————————————————————————————————————————

PACKAGE: THE FLASHLIGHT & ACCESSORIES

The Wuben E10 box arrived well packed in a cardboard box and wrapped in bubble plastic. Inside, the flashlight box was also protected by a plastic bag.

In it we find some very general information about the type of batteries to use, output, runtime, and other aspects.

Inside, we will find: Wuben E10, Wuben branded lanyard, 2 spare o-rings, Wuben branded holster, User Manual, and Warranty card.

Please note that this package does not include battery!

THE FLASHLIGHT
The Wuben E10 is being presented as a “suitable for one hand operation flashlight”! And I guess they are right! The flashlight can be used in a simple way and it’s shape even allows using it in “cigar” style if needed.

Not being the smallest 18650 light we will find, it has a medium size that is a compromise between EDC and back-up light.

Out of the box we find a very well built flashlight, with excellent anodizing, being this a Wuben characteristic, at least in the lights I have.

It has soft and matte anodizing, even the knurling in the tube and tailcap is not aggressive. It has some slight machined grooves in the head and tube.

The flashlight is sort of tube light, with lines that resemble a “bigger” Lumintop Tool AA/AAA flashlight!
It is composed by 2 parts (head & battery tube + tailcap), assuming that both the battery tube and the bezel are glued, which I didn’t manage to disassemble (yet)!!

About the engravings, it has the brand, model, serial number, CE info and the “hot” marks in the head and in the tailcap it presents the orientation of the battery for its correct placement into the light. (+ to top, - to bottom).

The threads on the bottom of the battery tube are trapezoidal, arrived well lubbed and are also well machined, with no traces of aluminium chips or dust. There is a thick o-ring to protect from water infiltration in this part.

The tailcap, itself, has 2 lanyard holes, a Wuben branded silicone button, and inside we find a somewhat “different” reverse clicky switch with gold plated tough springs.

Through the battery tube we can see the driver part. It seems to have the same type of springs, and also has a black plastic protection/insulation. Not portrayed in the photos, I can see some blocks of solder which I think they are keeping the tube “glued” or held in its place. I may be wrong, though.

Already installed in the flashlight we have a non-deep carry pocket clip, which attaches the light to our jeans or backpack. It is a strong clip, with good anodizing. Due to the tube shape, this clip is not reversible.

About the head, as I couldn’t get the bezel out, I can say that the Osram P9 LED is perfectly centred, that the bezel of the flashlight has some “grooves” (as a ‘tactical’ bezel), and that the lens is AR coated, with a purplish tone.

The bezel is smooth (SMO), and despite it is flawlessly machined, it provokes some rings in the beam as I’ll show later.

About the battery fitting, this flashlight accommodates protected and unprotected 18650 batteries. On the left there is a protected Wuben battery (from the TO46R) and on the left a sony VTC6.
I couldn’t test it with CR123As as I don’t use that type of non-rechargeable batteries.

***As there is no explicit information about Low Voltage Cut for this light, I suppose that protected batteries are the best option in order to avoid eventual drains.*¬

I may do a test later with some “depleted” batteries to test the cut-off voltage level.

The use of 2 Li-Ion Cells (16340s or 18350s) is not permitted as it will burn the driver.

About its dimensions and weight, this is what we get:
(I forgot to measure the diameter, I can do it later if needed. The specs indicate 25.4mm (head and tail, as the but is slimmer).

Just a small comparison with other lights and a Wuben family photo

————————————————————————————————————————

USER INTERFACE

This flashlight as a simple User Interface, composed by 4 regular modes (Low, Medium, High and Turbo) and 2 special modes (Strobe and SOS). All the operation is controlled by the tailswitch.
The flashlight has “memory”, but I will explain and show how it behaves.

FROM OFF:
Full press = ON.

FROM ON:
Full press = OFF.
Single tap = advances to the next mode
Double tap = enters Strobe
Triple tap = enters SOS

How does MEMORY work?
a) Turn the flashlight OFF > Wait about 8 seconds = flashlight will turn ON in the last used mode.

b) Turn the flashlight OFF > Quick turn ON (from 0 to 7 seconds) = flashlight will turn ON in the next mode. So…it also has something like “next mode memory”.

This is a weird and eventually annoying feature of this flashlight!!! I asked Jelina about this situation and reported that this “next mode memory” is not a nice thing to have in such a nice flashlight. I am waiting for a reply and will check what she says on this, to check if it is a feature or a “bug”.

Meanwhile, I made a video showing how the light behaves, basically showing the UI:

I also found out that if we are making a double/triple tap to enter the blinky modes and on the last tap we switch the light OFF, it will turn ON in the special mode we were “aiming” (accidentally or intentionally). To avoid this we need that 8 seconds wait… :person_facepalming:

As with the “next mode memory”, I also find this a weird and eventually annoying feature of this flashlight!!! I only found it today, so I could report back to Jelina yet. Will do it later.

————————————————————————————————————————

OUTPUT AND RUNTIME

Wuben seems to bet on good performance flashlights and this one seems no exception to that. I didn’t carry any tests yet on the drop down from turbo, and no tests on the light’s body temperature as well. Will do it later and post my relative and non absolute results.

Low : 1 lm ///// 514 h
Medium : 100 lm ///// 21 h
High : 300 lm ///// 6.5 h
Turbo : 1200 lm > 700 lm///// 1m > 110min

Strobe : 1200 lumens
SOS : 200 lumens

The levels are well spaced, not only on paper, but also to the eyes, being this a Wuben’s apanage as well.

————————————————————————————————————————

ACCESSORIES
As mentioned above this, flashlight comes with some accessories.
The pocket clip has been referred before and comes pre-installed in the flashlight.

The User Manual, as for other Wuben flashlights, is written in 4 different Languages (English, Deutsch, Chinese and Japanese). English is well written and explains pretty much what we need to know about this flashlight.
The points addressed in it are: Warnings; Products List; Product Features; Product Operation (Structure, Installation, Operation); Parameters; Optional Accessories; FAQs; Warranty Policy (Under and Beyond Warranty).
Not all the information about the light is there, so a quick check on Wuben website is a complementary way to get more information!

Some things I miss there, explicitly, are Low Voltage Cut-Off information and Reverse Polarity Protection. Especially once this light may use different types of batteries.

The holster is quite good as well. It has a place for the flashlight itself and also for spare batteries (1x18650 or 2xCR123A). That side compartment fully covers a protected 18650, avoiding it to be exposed or to fall.

On the back it has a permanent belt loop and another with hoop-and-loop fastener, that allows some more versatility to put it on/take it out!

The lanyard, is Wuben branded, as is quite similar to others used in Wuben light’s. It can be attached to the tailcap of the flashlight!

————————————————————————————————————————

BEAMSHOTS

As mentioned before, this flashlight uses an Osram P9 led. This is the first flashlight I have with such LED, so I’m still trying to compare it with other LEDs.

In this flashlight, mostly due to the SMO reflector, the beam divides itself into 4 visible zones: hotspot (homogeneous), corona (limited by a ring provoked by the reflector), spill and outer spill.

The hotspot is more neutral white, corona more yellowish, the spill and outer is cold white (and probably has influence from the lens).

I haven’t tried it yet, but this seems the case where a lens diffuser as Dc-Fix or similar, will act greatly!!

PWM & BEZEL
(LEFT)This light has no visible or non visible PWM. It has a “constant current control design” into the driver avoiding those effects.
(RIGHT) Due to the bezel shape, if the light is left ON while facing towards a flat surface it will be possible to notice this through the “holes” left by the bezel.

TINT COMPARISON
Well, probably not the best way to compare tints, but this is a comparison between the:
Sofirn C01 (Yuji 3200K) > Wuben E10 (Osram P9) > Sofirn C01 (5700K)

BEAM PATTERN
And these are some photos with the beam pattern.
Please notice (if possible due to the photos quality :zipper_mouth_face: ) that the ring is not only visible in a white wall but also on some darker places.

BEAMSHOT COMPARISON
I picked my Zanflare F1 (right) to make a 1st comparison of beam with the E10 (left).
In the next days I will post some more beamshots and outdoor photos to show the potential of this light and how does it compare with other flashlights!

————————————————————————————————————————

GENERAL IMPRESSION

The Goods:
1 – My general impression is quite positive, despite there are some aspects that are bugging me a little.

2 – The flashlight has tremendous quality in body construction and seems very reliable in terms of working and wearing.

3 – Also, even looking slightly “thinner” it is very robust and seems capable of taking a beat and being carried in a bag or a pocket for an extended period.

4 – Indeed, this is a light that can be easily used with just one hand, and the shape of it allows a cigar grip, that can be useful in many situations to get a sharper orientation of the beam. It also allows a comfortable grip when holding it “tactically”.

5 – The tailswitch can be modded, and I put a forward clicky switch in it as an experiment. The flashlight still behaved well

6 – Despite not tested, the runtime that this flashlight offers in Low mode is a good plus when travelling and going out for some place! It is indeed a positive aspect.

7 – The holster, well done, slim and practical is a great accessory

—————/////—————

The “suggestions to improve”:
Apart from personal preferences, there are some things that can make this flashlight a hit. But they probably need to change.

1 – The User Interface. Having next mode memory when turning OFF/ ON quickly is quite annoying. Even if I was a muggle, I would probably complain. Specially when we need to wait around 8 seconds to “fix” the last used mode.

2 – The double/triple tap & OFF. In my opinion, if the light is turned OFF even if it was double or triple tapped before, it should turn ON in a regular mode, not a special mode. Special modes, in my opinion, shouldn’t be memorized at all, even if by accident.

3 – The reflector / beam pattern. The perfection on the reflector machining provoked that artifact in the beam and it distracts me most of the time. Maybe a Orange Peel reflector would improve the beam avoiding rings and also the shift it has. Or, changing the profile of the reflector itself, maybe it helped…

4 – Low Voltage Protection & Reverse Polarity Protection. I guess this should be specified well in the Manual.

—————/////—————

SUGGESTIONS BY PERSONAL PREFERENCE
Simple:
1 – Change modes (Low , Medium , High , Higher + Turbo + Strobe) and implement double tap for Turbo, triple tap for Strobe.
2 – I will not say “abandon memory” because sometimes it is nice to have a light with it. But I wouldn’t be annoyed to have this light without memory!!!
3 – At least Neutral White LED would also make my day

This said, thanks Wuben for sending the light and thank you for reading.
Comment, question, critize folks

Best regards!

EDIT #1:
Diameter measuring!
I forgot before, but here it its now.

LED Closeup!
Here is a closeup of the LED, lighted and OFF Sweet

EDIT #2 (6 July)
Table’s reformulation

Drop Down and temperature
Please see this values as mere indications, and not as something strictly scientific. They intend to show how the light behaves shortly.

Please note that the light and luxmeter have been moved between tests, so let’s not focus on the exact values but on their behaviour!

So, in the common checkpoints we have between Test 1 and 2, the drops are not that distant, revealing consistency and agreement with the specs (after the 1 minute, it will drop and the stabilize).

Within the same period of time (0 to 2m30s) the temperature rose about the same thing between tests checkpoints, although on the Test 2 the starting point was already higher as I didn’t let the flashlight cool down completely.

Thank you
BTW, I updated post #2 so you can take a look at the LED from the closeup

Also added photos with diameter measuring, and tables with luminous drops and temperatures.

mrheosuper · 2019-07-06T15:13:30.000Z

judging from your pics, the die of this osram led is a little bigger than xpl-hd

Did anyone overdrive this led, i’m interested in this led

I guess you are right! I don’t have an objective way to compare the LEDs, but the P9 seems to be larger but shorter in tall than an XP-L HD.
This is a photo side by side with the Klarus XT1C with XP-L HD. (click for bigger image)
In abother perspective that I can’t quite capture on camera, the XP-L looks taller, but I can’t be sure.
The P9 dome is wider and has bigger “yellow” area.

TrueRMS · 2019-07-06T16:02:51.000Z

What exact led is this? It appears “P9” is just nomenclature as a Google search for “osram P9” returns results for a wide variety of LED’s from high voltage COB arrays to single die, medium power, no thermal pad having but super high light quality emitters.

Hum, maybe it is this one:
OSCONIQ® P 3737 (3W), GW PUSTA1.PM

ams-osram

OSRAM OSCONIQ® P 3737 (3W), GW PUSTA1.PM White LEDs - ams-osram - ams

High-power LED with high performance, superior robustness and long lifetime.

(had to shrink the URL due to error)

I actually don’t know and don’t have much information from this one but it has similar look to the one in this flashlight!

BTW, I reformulated the tables above into this, trying to put the info together:

Interesting led-choice, it seems to me that the Duris in its specificationshas no advantage over the Oslon Square.

I would like to say something relevant about that but I have no clue about that djozz :person_facepalming:

My impressions on this led are mostly based on what I see, than about specs or performance.
I still have to test it tonight to check how the beam looks in the real world. So far it seems to produce an interesting white (neutral) beam mostly noted on the hotspot.

Not sure about other information.
I wish Wuben could publish that information more clearly on the LED, specially as it seems to be a quite unknown/recent one!

BTW, based on the specs would you say this is a good performance LED?

djozz · 2019-07-06T18:49:25.000Z

Yes, it is a good led but floody.

TrueRMS · 2019-07-06T21:03:31.000Z

Just noticed thermal pad is not neutral (it’s led-). Yuck.

Assuming it’s the same thing as identified above: Datasheet page 14 (not pdf page 14, actual page 14!)

Look at the pad layout drawing on the right, it labels both the cathode strip and the center pad as “cathode”.

EDIT #3
Beamshots & Comparison with other flashlights

Grip

Beamshots
Here are some “stand alone” outdoor photos of the Wuben E10 beam and range. This light has an intermediate beam, not being very floody (despite the Led) but also throwing a good distance well above the 100meters and at almost 200meters as the photos show.

Beamshot Comparison
Part 1 – Comparison with Nitefox UT20 (XML2 CW, SMO, 4 mode – 1000lumens) & Zanflare F1 (XP-L HD CW, SMO, 4 modes used - 1350lumens)

I opted by these 2 comparison lights due to the type of CW LED they have, and also because of the mode spacing that is somewhat similar to the Wuben E10 . However, the Zanflare F1 modes used were ML , L, M & Turbo, meaning that High was not used.

ORDER: Nitefox UT20 >>>>>>>>>> Wuben E10 >>>>>>>>>> Zanflare F1

1

2

3

Part 2 - Comparison with Zanflare F1 (XP-L HD CW 1350lumens)
In this part I will only make some comparison with the F1 due to the lumen output, that is higher in this flashlight. The UT20 is good, but being around 900-1000 lumens and XML2 Led, it stays a bit below the E10 specs , so I shortened the competition.

ORDER: Wuben E10 >>>>>>>>>>>>>>>>>>>>>>>>>>>>Zanflare F1

OVERAL APRECIATION AFTER THIS!!

So, this light is quite incredible in outdoor environment! It doesn’t do something that others don’t do, but it is very competent and has a very nice throw and intermediate beam that I wasn’t expecting.

Outside, the rings in the beam that were felt indoor, are not felt anymore as it blends with the environment. It matches the competition of several different types of lights such as the ones I tested, but I believe that it’s stability will take some advantage throughout the way if compared again.

Being coherent with what I mentioned in post#1, the UI is the things that will bug me the most in this light. If it had no memory or at least a real “last mode memory” it would be a winner. But not knowing which mode I will get when I turn it on is kind of a bummer specially if used constantly. Used as a backpack light, however, it will be great, as you would remember the last used mode probably. Also, its performance and also the blinky modes make it a great light for “emergencies”.

Yeah, indeed it took me some hours to put all the things together, photos, gifs, text, tests. Still, it is far from the rigour that many members here are able to offer, or demand, and also it its far from the “number exhaustion” that many folks can do!

I hope you appreciated it, though

Great review! Very thorough. An inspiration to other reviewers.

One minor typo… in one place you wrote “THE FASHLIGHT”… missing the “L” after the “F”.

Great review! Very thorough. An inspiration to other reviewers.

One minor typo… in one place you wrote “THE FASHLIGHT”… missing the “L” after the “F”.

Thank you very much for your words and also for pointing the typo, I corrected it already
BTW, I’m not sure about the inspiration, I just do what I can to show the best I can how a flashlight is and what it can do
