Review: Wuben D1 [20% off coupon added]

Update:

20% discount code:

UN20D1

https://bit.ly/3C8fJEo

I’ve reviewed the D1 on the TLF and planned to completely translate it for the BLF. Fortunately, MascaratumB already did all the tedious work here Party

So, I’ll just add a few missing pieces and my measured data.

Thanks to Cindy from Wuben for sending me a review sample!

The D1 is targeted at hiking, camping, and general outdoor things. IP rating is ok for this (IP68, 2 m wc for 1 h), impact resistance (1.5 m) also. The ultra wide beam (spill 175 °) makes it imo more useful indoors, especially larger rooms/buildings, e.g. urban exploring.

MascaratumB did all the praise and critics already, so let’s stick to the facts:

Technical Data

LED XP-L Hi, 6500K
Max. lumen 1100 (ramping down to 400 within 30 s)
Max. const lumen 400 over 2 ½ h
Min. lumen 5 over 150 h
Max. range (ANSI FL1) 130 m (4200 cd)
Max. range at start 157 m (6200 cd)
Max. range at 400 lm 100 m (2500 cd)
Width of spill 175 °
LVP Yes, standby when battery voltage lower 2.8 V
weight (f/l and f/l+battery) 64 / 117 g

Optics

This kind of optics has been discussed on BLF already.

Wuben D1 on canvas:

Runtime graphs

High

The first few minutes show that the initial brightness is reduced within 30 s. After that, the D1 maintains constantly 400 lm.

Medium

The specs are not met here probably since the battery was not fully charged (stopped at about 4.18 V). Still, runtime with 300 lm is impressive.

Levels

Nice exponential ramp (cd measured).

Mode High Med Low Moon
Lumen 1100 – 400 300 100 5
Time 30 s + 2,5 h 5 h 30 h 150 h
Current 3 / 1 A 710 mA 165 mA 9 mA

PWM

None. There’s a little ripple, but not noticeable:

Moon:

Low:

Finally … the breathing:

Love

I think that’s about it for now. I’ll add outdoor beamshots probably tomorrow.

Thanks for reading,

Thomas

Here we go:

Moon – Low – Med – High

ISO 800 / 0.7’‘ / f 4.5

Focal length: 18 mm on APS-C

Edit: The reflector is 23 m away (thanks notta for your comment).

Hey, Unheard, thanks for your data and also the correction about the LED used in this flashlight. Thumbs Up
I would never guess it is XPL-HI, always thought they would go for Osram.

I will correct my review Thumbs Up

Also, thanks for the stepdown and runtime data Wink

You’re welcome, MB. And thank you for your wonderful review and personal insights on this light.

Yes, the Osram is often used [in cheaper lights, right?], and Wuben is somewhat silent about it, except for the blog entry. Can’t understand really. No need to hide any information on this light. Seems to be top notch in every detail.

Thanks for your words, too, Unheard Wink

Hum, the Osram seems to be used in several lights (E10, E12R, H3 but also L50, C3, the new T2, and eventually others), some of them are not “cheaper” although they are not their “top lights”.
I remember that someone commented that the P9 would be an efficent LED, so maybe Wuben opts for that one due to that (in combination with their already efficient drivers). Just like Olight opts for some CW emitters.

After all this time with the D1 I wasn’t able to open the flashlight bezel. I guess I may damage it hard while trying so I am not sure how much I will be able to dig into the head Big Smile But if I can, I’ll show it Wink

Thanks again Thumbs Up

Not that Unheard’s review is useless. It corrected a led mistake. Butt ya I much prefer Mascaratum’s review primarily becuz he doesn’t resort to MIT-style graphing in a guise to appear defacto more scientifically accurate and relevant. Also he doesn’t need to banter that he posted it on TLF butt is doing us a favor by translating (usually inferior) from his native language into our’s.

To wit…..“I’ve reviewed the D1 on the TLF and planned to completely translate it for the BLF. “

Geez I can hardly wait. I think I’ll just learn German. Who needs inherent translation inaccuracies which then I gotta double check on cuz it doesn’t read quite right? Ya know German into English is no easy feat. Especially German. LOL

There’s a human touch there in MascaratumB’s which gives the reader the sense that he actually really handled the flash in a real-world diverse environment and not in some confined apartment or out in some back alley with no distances or heights indicated to give an idea of proportionality and perspective. Those kinds of details are important in a quality review. This said in hope Unheard benefits from constructive criticism.

The current extreme over use of impressive looking graphs describing the attributes of a given flash when instead using a simple direct informational statement is better, goes something like this……

“The flash ran for approximately 5 hrs at approximately 300 useful lumens then suddenly dropped off to where Vf kicked in and then it died was nonetheless especially impressive from a single cell.” No large essentially sometimes confusing graph necessary taking up bandwidth trying to “scientifically” say the same. Save any graphs for truly complex notions.

Well, just being Notta here I guess. Wink Shocked

PS. Watt’s the TCR look like? Oh that’s right TCR doesn’t enlighten. Ok, how about CRI specs vs watt ya see? Oh that’s right ya can’t trust watt ya see color-wise butt ya can trust reading PWM in a random apartment’s hallway. Gotch ya.

Thank you for your comments, Whacky. I’ll see if I can find better locations for beamshots.

Sorry if that sounded arrogant. It was not meant to and I had no idea you’d see it so. Keep in mind english is as difficult to master as german. Grammar is easier, but expressions are likewise critical. Wrong wording can (obviously) turn a neutral statement into something harsh.

So, to explain: I really thought people could see this as addition to MBs review, find here some data that might be interesting. Cindy never asked for a review on BLF, my only intention was to show some additional information.

Hope you understand.

Oh I understand alright. Nice snark. Ya know, “Whacky”. Actually my comments were meant to show your true demeanor. You try to sound nice and demur after yer nailed but in effect it’s just snarky retaliation, right?

PS. Just post yer TLF review in German here. One can use Google translate which will prolly be almost as accurate and maybe moreso in certain cases than an inferior English translation attempt to begin with. I mean unless you’re a professional German to English translator. I can only imagine how hard TLFers would laugh if someone took an English review and tried to amateur-translate it into German. No offence butt us Yanks kinda do the same cuz it just doesn’t come across quite right to our ears, ya know? LOL Shocked

Re your edited posting: I measured CRI 72 with substandard equipment. Can’t tell by eye.

I have two classes: Acceptable for the intended application or not. The D1 belongs to the former.

Edit: Calm down, mate.

How about you do the same instead of constantly calling me insulting disparaging names then? That’ll improve things right off the bat.

How do you come up with CRI 72? Watt does the manufacturer internal specs say? Your CRI equates to something like a 6.5 on a TCR rating. Sounds too sh*tty to me. Or 7 total TCR flaws. I doubt it.

Measured with an Opple Lightmaster III, which is not a true spectrometer, but uses color filters and CCD, probably just a regular Bayer-matrix.

I have no part number of this LED, so can’t tell. It is likely a ‘Minimum CRI 70’ version.

Not a ‘conclusion’. Conclusions have to be anchored beyond guesses which this was. Totally. Just took .5 × 7 = 3.5 + 6.5 = 10 TCR. Pulled it outta my a*s just to illustrate watt if. LOL Butt was hoping ya had a least some kinda Reference Standard flash in hand that CRI’s well enuff to your eyes so that ya could reasonably assess to compare. Substandard equipment is no way to go through flash analyzing life. Butt I digress.

Ya havta have a Reference Standard to start with, right? The best most affordable way is through a flash. If you could get an Ozark Trail OT 50L which Reference Standards to a TCR ‘10’ for example you’d have that for an investment of $1.00. You must have something around over there that compares to the OT 50L’s TCR capabilities I would imagine?

PS. The true litmus test for determining TCR is shining off the color White. If your flash because of color-temp or tint influences pure White to look other than what it is in sunlight then ya got a TCR problem that could be important depending on its application. Like for instance reading all the colors in electrical wiring. The OT 50L shines off white just the way the white looks in sunlight. No flaws. No tint pollutions, etc. Just plain white is white. And that’s why it’s a TCR ‘10’. Grad

Yes. That will be the sun. Some may find it too greenish, but I always liked it. If it were on sale, it would be mine. Not that I’d dislike rosy tints, just the opposite. I have lotsa sw45k lights and like them indoors.

Ok Notta, you want to know how colors are rendered under the light of the D1, right? The answer is: Sufficiently well. Actually rendering is so good I don’t see where I would benefit from a higher CRI, taking into account lower output and/or runtime. There are mostly academic discussions ongoing about shades of green or brown in reflected light, and the probabilty you’re getting into a desaster when dandelion leaf looks like daisy leaf, but this is pointless in actual use. Todays CW LEDs are all good, at least the common ones. TUV (True Usablility Value) of 10.

Ok ya admit official CRI numbers are unknown at this time. Yer equip ya admit is substandard. So ya havta go by yer eyes that CRI is essentially excellent.

Fair enuff. Your eyes don’t necessarily lie, do they?

And you just made one of my main points in that TCR although subjective can also be more accurate than measuring equipment. Along those lines then the D1 may become yer Reference Standard moving forward in future reviews as it’s so good for TUV/TCR – since ya can’t get an OL 50L to do a side be side comparison.

I can confidentially now assume If the D1 is that good at TUV and TCR then I would bet a U2 boatload of Nitecores that the official LED CRI will be more like 90 or so. Certainly not 70, correct?

So by your TCR assessment I now might be more inclined to order a D1 someday. I sure as h*ll wouldn’t even consider it at CRI 70.

PS. Get rid of inferior equipment. It does ya no good credibility-wise. Yer eyes are clearly and by far more accurate. Shocked

Yer thread. Done. Bagging out now as requested. Have fun. Smile

At now reconsider the outdoor beamshot. What do you see? Not so much from the trees, I admit. It’s a location I used for a more throwy light also.

You see the concrete (grey), red clinker bricks, a green door, quite a standard color, easy to see if it’s rendered good or bad. The socket of the building is dirty white. You see a reflector in the rear part, the only thing indicating the light is on in moon-mode. Distance is 23 m to flashlight. There’s a tree right behind it.

Anyway, like what you see?

And it’s not only about rendering, look at the spill. Focal length of the camera is 18mm. Light everywhere. Ask if you want a comparison with a reflector light.

That’s what this is about, showing what the D1 can do. Amazing, isn’t it?

Excellent TCR assuming yer camera is accurate. I would likely give it a ‘10’ based primarily on the dirty white rendition and grey transitions. I see no overlaying tints either. I see no flaws. Beam is superb. Well done, Wuben. This again is likely a CRI 90 led or better.

I think you have a TCR Reference Standard now in yer hands. So now ya can compare yer other flashes ya have to this.

The only point I’m further curious about is the reflective sign on the brick wall.

Watt sunshine color is it?

Since it appears you and the camera are in great sync, could you take a noonish sunlit shot of everything too? I don’t expect any surprises butt it wouldn’t hurt to have it either.

In any case depending on price I’ll now prolly get one. Then I’ll reassess watt I see against especially whites and if it’s flawless I’ll put it in my signature as a TCR Reference Standard as well.

Congrats. Grad Thumbs Up Beer

PS. The browns/beiges in the far tree trunk is another tell here. This is most likely a TCR 10 flash. Flawless.

Nice review, sorry they are giving you such shit here. It’s a nice enough like but the UI leaves a lot to be desired in 2021. I personally did not like the cold white, low CRI output but that’s open for preference. If they are using an XP-L then that’s way behind the times too…
