Discussion : - Utorch UT01

Yeah, their free shipping has been very unreliable as of late. One of my orders took 76 days to reach me, although, most of this time it sat in US customs, so it’s not exactly GB’s fault. If it’s anything over $10, I just break down and pay for express shipping instead.

That’s why I like Aliexpress, they have delivery time guarantees. Gearbest gave me a hard time getting a refund for an order that hadn’t arrived 4 months after the purchase. I’m hopping Banggood is better, but I have a bunch of orders that shipped but never checked in my country more than 30 days after. I’m hopping it was just the holiday delays, but other orders from around the same time had passed through

To keep on topic, onde I get it I might be able to do a side by side review with the Sofirn SP10A (old driver) and Lumintop EDC05 (if it also arrives this year). I plan on using mostly with AAs, but I might run a test with 14500

Same problem here. The indentations are a bit worrying, but so far none of my batteries had any problems.

Just cut 3/4 the length of the outer thick spring and after the problem. All my batteries work perfectly and are not damaged.

Grateful for this thread. I think I read most of the posts. I have 2 UT01’s on the way. now I know what problems to look out for if they come with it. So basically there is 2 issues that may arise. One being the switch which someone mentioned fixing with a 1.5mm plastic filler under the boot. And the biggest one was length of body tube could be short so connection issues and driver crushing. Solved by a copper filler. Or cutting the outer spring a bit?

I received 2x UT01’s a week ago and one is on its way, no issues with power buttons so far and I received 4x 14500 button top batteries today, these fit nicely:
Soshine 3.7V ICR 14500 900mAh Li-ion Rechargeable Battery


amazing deal on those batteries!

Yeah, these batteries are really nice, people get between 840mAh and 1000mAh in the Aliexpress reviews and you get also a battery carrier.

Good suggestion. Thanks!

I guess I need to backread as I received my UT01 a few days ago and absolutely won't turn on. Sigh.

I think this is the last time I'm ordering FL online as the return policy and shipment is too much of a hassle :(

oh, I only know a flat cut.
What effect has this pyramid shape on the beam?
Or is it more a cone?

Joe

In total, it’s a pyramid and I do not know if it changed a lot, unless I actually do it flat.

Got my third. Needed wire to work. Still no turbo with good battery. Did engineering mode and got turbo. Happy.

I gotta say for 10 bucks it’s a very nice 14500 EDC light. Seems well made and looks much better than any of the pics I had seen.
I may replace the driver and UI but just to beat around, it be fine without the swap. I just can’t help myself, it’s screaming mod me.
Over all I’m very pleased with the light, better than I was expecting.

Yes, it is a nice quality for the price, packaging is good, ordered my fourth yesterday because it is easy to gift since it also works with AA and has presentable packaging.

I approached the subject again and scalped the diode completely. Now it resembles the HP-L HI version. For this I changed the paste and polished the substrate diode because it was not equal. Effect? Wow, it shines noticeably harder. Of course, I made measurements:

Before changes, 114 lux with 5m:

After changes, 156 lux with 5m:

And some photos from the modification:

^ looks good! :+1:

Does anyone encounter this issue:

UTorch UT01 occasionally (or fairly regularly) will not turn OFF (have to unscrew the tail cap in this case):

Maybe it’s an electronic switch problem? How to fix it?

Hi dear, where did you get it for ten bucks?

thanks
