Group Buy: Wuben TO50R HC ("The Flashlight") - 90+CRI, 2500+lm, EDC - CLOSED!

Maybe that fade is working similar to a soft start …
I wonder if it was designed that way, or resultant.

Probably a resultant of the boost driver circuit that gradually discharged itself once the power is cut off. I’m not sure of that though but seems logical if there is a capacitive effect involved.

EDIT : A pity that there is no glass lens in this flashlight. :person_facepalming:

I think the fade out may be due to the phosphor that is used. Fluorescent tubes have a fade out, or decreasing afterglow that is similar.

All the LH351Ds I’ve used have a slight glow for 5+ seconds after being turned off.

My Zebralight have a a much more noticeable “fade” when shut off too, always assumed it was the boost driver.

This board could be configured as 6V or 12V but not sure if it could actually be modded to fit with no screw holes.

CCT taken at “High”

CCT = 4816K (Duv 0.0040)

Color Rendering Index (Ra) = 90.1 [ R9 = 52.4 ]
R1 = 89.7 R2 = 91.2 R3 = 92.9 R4 = 91.5 R5 = 89.7 R6 = 88.4 R7 = 93.6

Moon: 0.57lm
Micro: 14lm
Low: 56lm
Mid: 272lm
High: 1333lm
Turbo: ~2680lm at 30s

Tail standing for like ~8-10 minutes on turbo got about 930lm

Thank you Contactcr for the values! That’s interesting, it confirms my impression that the CCT is a slight bit under 5000K and the CRI right around 90.

I just received mine today and this is a great light! I’m already liking it very much!
I definitely appreciate the ability to run on high for lengths of time, running a battery with enough capacity to support that. The Moon is a great level, and I’m very happy about the nicely logarithmically spaced brightness levels!

Just got mine today and I love it so far!!

I got mine. Looks like 2 legs are crushed :confused:

Pink color - holes for legs on the mcpcb.

Does anyone else have this problem?

Edit:

This post shows the cause - there are screws in wrong holes. Just like E07 :person_facepalming: :weary:

Edit 2: prototype version looks OK

My first of two arrived … I love it. Installed my Towild silicone diffuser and instantly turned my new TO50R into a lantern. The Towild diffuser is a perfect fit. I am super pleased with all aspects of this setup. Acebeam 21700 5100mAh batteries are a perfect fit as well … :slight_smile:

Mine is also broken


Mine also - guess they all have broken legs

Have not received mine yet. Tracking shows the package has not moved since 12 days. Last time I saw that, the package was sent back to China because of li-ion battery and tracking will not show you that. I wrote to Jason from Wuben 2 days ago to check if they did not received it back but I never had any answer…

:neutral_face:

These legs are specially broken to screw mcpcb into the flashlight. It’s the same in D4. Look again at my comparison picture:

The screws are in good holes. These next to don’t coincide with the holes in the flashlight.

The prototype had no screwed mcpcb.

I also think that all four legs should be untouched, and screws in places intended for this purpose.

But what will you do …? ¯\

I would say that is because they drilled the holes in the wrong place. The mpcb looks perfectly fitted for screws in the adjacent hole with enough space to fit the optic in without issue. Someone, somewhere along the line screwed up and they used a patch job to fix it…

By the way has anyone else’s flashlight come with oil and aluminum shavings in the top threads? I had aluminum shavings underneath the o ring, in the threads, and inside the battery tube that I had to clean out when I got mine. The bezel had machining oil on it as well, inside the three indentations. Also, aren’t the square threads a bit… thin for what you would normally find on a flashlight of this price? It’s a nice flashlight and all, but the build isn’t exactly up to snuff for what it was billed as. The finish quality and attention to detail of my C8F is above that of this flashlight, and I paid significantly less for it. I know we’re mostly paying for the driver, but still…

I disagree, you can clearly see in the photos from straight above that the unused screw holes are further in from the edge of the MCPCB, I can’t imagine them lining up with where the screws are actually mounted.

The finishing issues sound like a bummer though.

My point was that the screw holes themselves were cut in the wrong place because there is nothing that could possibly be obstructing them to prevent moving the screw holes a bit inward. The only things that need to be there are the aluminum that forms the shelf, the wires (which run down the center), and those two screws.

If you want the LED to be aligned in each corners of a square when you are holding the flashlight with the switch above, two legs of the TIR need to be on the vertical axis, the 2 others are on the horizontal axis.
They drilled/tapered the 2 holes for the screws on the horizontal axis while they should have drill it with an angle compared to the horizontal axis, right here :

They used 2 holes reserved for the legs of the TIR so they needed to cut it.

Ah I see exactly what you mean, the screws are 90 degrees from the leg holes vs those spots being used for the legs.

I guess I’ll give them the benefit of the doubt and assume there was some reason for it? I know the D4 and PL47 both cant fit all 4 legs of their optics for whatever reason either.

Got mine today, nice quality beautiful beam and tint.

Knurling pattern is very attractive but the entire light is very slippery in hand.

I wonder if I could bead blast areas of the surface (to gain tactile grip texture) without removing the anno completely.
