my Manker E11 is very warm too, much warmer than neutral. Like a yellow-ish beige. I use it late at night for its warm-candle glow. Although with a low CRI, its really nothing to get excited over, IMHO.
[EDIT] But I still think its in the āneutralā 5000K-ish range. Its still considerably more pale than my Surefire incans. I really donāt notice it until I directly compare the two on a white wall.
Yeah, i think itās not 5000k
at first i think they sent me wrong one, then i checked again
One thing for me personally in regards to LED tints, the temperature I see heavily depends on what color my brain happens to be pre-calibrated to. Staring at the pale-blue colors of the BLF forum for example shifts my perception to a colder nominal, so then when I look away everything looks slightly warmer. Try thisā¦ white wall hunt with your warm tint light and note its color temp. Get a yellow-orange construction paper sheet and hold it right up to your face. Shine the light at the paper with it up to your face and stare into the bright orange color for 10-15 seconds, blink a few times. Now go back and white wall huntā¦ what tint is the light now?
Will try it, when i have time and orange paper(:P)
I know our brain is not perfect, today i use ut01 all time, and now all my flashlightās tint are silghtly cooler
I had the same issue with Manker U-11. I won this light and requested NW tint but tint is yellow. Closer to 5A than any other tint. Nowhere near 5000K. Shit Tint Happensā¦
jesus what happen with switch in that flashlight :person_facepalming:
I didnāt receive my UT01, after something like 8-10 weeks, so I submitted a ticket, and paid a little extra for GearBest to send me a 2nd one. I asked if they could test the light before sending it, given all the switch problems reported, and the person told me that all units are thoroughly tested. Weāll seeā¦
I recently got mine and Iām lucky that I havenāt had the switch issue, but Iām having a different issue. I canāt get Eneloops to work consistently. Sometimes it turns on, sometimes it doesnāt. Sometimes you put an Eneloop in and it turns on, then you set it aside for an hour and try again and it wonāt power on. I have no problem using alkaleaks. Works flawlessly every time and just by eyeballing it, both cells appear to be the same length or very nearly so. I just donāt get it and it seems like some of you are using NiMH cells. Any ideas?
Also, Iām disappointed that my Orbtronic protected cell doesnāt fit (should have read this thread first). There are some good suggestions in this thread, should we compile a list of IMR cells known to fit/work?
Also, looks like Iām not the only one to get the āsurpriseā warm tint model. I actually prefer this tint so I have no problem with it. :+1: 
I have a complete dead light and wait for respond from Gearbest, but I have already collected a list of short protected LiIons :
My meassured Tube UT01: 51,9mm x 14,75mm
No guarantee for the list, these are only mentions from other people
- Marsfire
- Trustfire
- AW (short maybe to long) https://www.akkuteile.de/lithium-ionen-akkus/14500/aw/aw-14500-lithium-ionen-akku-3-7v-750mah-protected/a-17006/
- Xstar 800mAh
http://www.xtar.cc/products_detail/productId%3D43.html
- Soshine 14500
There are different infos how long LiIon can be, maybe tolerance from tube or battery
50,8mm wonāt work
50,3mm yes
Q: Manker E11 - Review / Vorstellung / Test | Taschenlampen Forum
The lamp is 84mm long, not 82mm as in the description.
If everything is to long I would go with two 0,5mm thick rings in the head and the tail. Lose in the tail, in the head I would use two solder points as fixation to prevent shorts.

Thanks for that list Joe. Interesting that the Nitecore NL147 works. I wondering if others have had success with the NI14500A cell? I believe Giorgios mentioned using it as well. I think Iām more interested in using an IMR cell in this.
Hope Gearbest can straighten out your issue!
I have two of these lights now. The first one had a faulty switch which made it nearly unusable, so I contacted GB and they sent me a replacement. The replacement is now the wrong tint at cool white, but it works perfectly. Very frustrating. Also, they asked me to respond to the following :-
āPlease follow these steps and kindly answer the following questions, in order to help us review your case:
-Does the package show any signs that it has been tampered with?
-Please send us clear pictures of the box at all angles, including the shipping labels.
-Please tell us the outer weight indicated on the box.ā
:S
Hey no guarantee for the list, itās just what iāve read.
Interestingly some batteries are shorter on the manufactor website than on sellers websites.
So GB have refunded to me, at least their supports work well
17$, what should i grab now
Iām still waiting for mine to see how I made out n the switch lottery.
It is taking an unusually long time to get here. Ordered on Feb 12th but according to the tracking it arrived in New York on the 23rd and has been there ever since.

You can grab another if you still want one working UT01.
Iām still enjoying using 3 UT01 and no sign of switch malfunctioning so far under my normal use.
Hope the switch will last a good time
I dont want another waiting 20+ days just to receive d.o.a product, too risky
Klarus mi7 maybe is a good choice, but the price is quite high
There are codes available for the Klarus Mi7 so it is only a few dollars more. Check with M4D M4X.
The reason I chose the Utorch over the Klarus is the mode spacing.
Bob
Thks, i will pm him
Unprotected 14500 WindyFire button top IMR works perfectly in UT01. :+1:
ETA: WindyFire is an exception to the āFireā rule of batteries. It was tested and approved by HKJ.

Iām using a MXJO IMR 14500 700mah unprotected high drain. Got it from IMR batteries. Works good.
