Discussion : - Utorch UT01

Thanks for sharing. I may end up using this light with a 14500.

Not the highest quality torch, but it’s not bad.

I got one during 11.11 event in NW XPL V6-3D

But compared to my other lights including the Q8 it is definitely a 4000K emitter
anyone else have too warm emitters?

My Manker E11 is very warm / amber colored while the UT-01 is pale white.
Both were the NW version of each.

Same here. The one I received a couple of weeks ago seems warmer than 5000k.

Mine too.
I like it.
But the switch problem… :person_facepalming:

too warm for me, sounds like they get a ticket

I ordered the CW version now, hoping I will like it better. Just keeping my fingers crossed that the switch is not broken.

I mentioned the 4000K two weeks ago in the other UT01 thread. I like it too, but it is way off the 3D tint that the site and the package claims.

Last night I was comparing some lights.

I have some 5A tints in other 1xAA lights (emitters that I got from Intl-Outdoors), and these ‘alleged’ 3D UT01’s are remarkably close - which is fine by me. :+1:

I have Astrolux S1 3D (neutral white), the tint of which I like.

Comparing the UT01 neutral white (supposedly “3D” tint), this is a much warmer — in fact I compared it with a Convoy S2+ (XM-L2 T6-4C tint), and the two tints are closer to each other, or the UT01 “3D” could even be very slightly warmer…

Decided to do some more pics while I’m at it…

Not a fan of this NW tint on UT01. I’m hoping I like the CW version better.

Any idea about the current draw or lumen output for those three options on the firefly mode?

How did you know yours were off-center?

Here are some Lumen output numbers with NiMH…

Not sure what it is with a 14500.

Thanks, I only use eneloops so I don’t want to know 14500. I’ve been reading a lot about UT01 in this forum and it seems there are problems when using NiMh so I guess I won’t be buying this and go for Sorfirn SP10B instead.

That would probably be wise.
I am not sure what the current draw is. FWIW I leave my UT01 on candle mode overnight all the time… many nights in succession. I use it as a nightlight with a 2000mah eneloop.

I got my CW UT01 finally. For walking outside, I think I do like the CW tint better.

CW and NW optional?

Welcome to BLF LTVictor.
The light is available in Neutral white or Cool white.
I have the NW and it is warmer tint than the described 5000K. I would say closer to 4000K.
