LED Flashlights ā€“ General Info 1 x AA / 1 x 14500 Flashlights
150

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

151

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

152

I gotta say for 10 bucks itā€™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 canā€™t help myself, itā€™s screaming mod me.
Over all Iā€™m very pleased with the light, better than I was expecting.

153

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 itā€™s an electronic switch problem? How to fix it?

157

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

thanks

158

Check this one

Thanks a lot

Anyone know the maximum amps a utorch ut01 will draw with a 14500?

Deciding if I should go with a Sanyo UR14500P (better at ~ 1A or below) or an Efest 14500 (better at say 2A-5A but less capacity)

161

About 2 amps. I have used the Sanyo several times in the ut01 and they work fine. I have used the efest to, I donā€™t see any noticeable difference between them in the ut01. If you need more current than 2 amps in another 14500 light go for the efest to use in both.

162

Is there still a way to get it for 10$?
Thanks,

163

Right now its going for a little more, if youā€™ll keep watching Fin17 thread Iā€™m pretty sure it will pop up again with the special price. You could PM him which you will have to do anyway when the deal comes up again. The code is not public.

164

Thanks Iā€™ll do that!

The switch on the board gets a bit of center so the boots rubber nub doesnā€™t get good contact to the switch on the board, actually the rubber nub on the boot is really to soft and bends to much, so you have to take the retainer and boot off and get the switch centered and then it will work great, I did a picture write up during a group buy for the UT01 & 02, it was a buy put together by George, I think Iā€™ve spelled his name wrong but itā€™s close,

Edit: By the way to take that retainer off if you donā€™t know, I take a small screw driver and carefully pull back from the sides of the boot to pull the boot edges out from under the retainer and then with the boot out I can take a bit bigger screw driver and gently pry up around the retainer to remove it being careful not to bend it, itā€™s soft alum, the retainer is just pressed in.
Then take your small screw driver and put it on the side of the switch box, itā€™s normally off center to the left of what would be centered but anyhow then gently just pry it over until itā€™s centered then put the boot on and then press in the retainer and your good to go.
Iā€™ve had very few that Iā€™ve had to do that more than once, great little lights or they were anyhow.

However, I could not withstand this yellow color and today I replaced the diode on XP-L HI U6-3A. The end result is pure white in NW 5393K and a bit more focused beam. I did the same with Lumintop SDMini, which only occurs in CW 6500K. It bothered me too and the same diode was also in it.

Good day
my Utorch UT 01 NW worked perfectly for 7 days.
Then the problem is not possible to switch on with the button.
if I want to turn it on, I have to let go and tighten the battery cover.
does anyone have similar problems?

168

Yes, I have that kind of problem with my UTorch UT01. Occurs relatively frequently (lately more often than not).

Sometimes, not possible to switch off, then after unscrewing, may not be possible to switch on. But wait some time, and it mysteriously works again. Thus far, it hasnā€™t gone totally unusable (I donā€™t EDC this ā€œintermittently-workingā€ flashlight, itā€™s now relegated to testing purposes only)

169

Okay, thank you for the answer. - I will wait.
Utorch is good - power and light color NW, I use ENELOP 2450 and SOSHINE 900 mAh 3.7V batteries, this battery probably wants batteries at higher current consumption probably buy efest.
the bug has one advantage - the flashlight does not turn itself in the legs ...
