I found a resistor on the driver marked .050 so I piggy backed a .100 and didn’t see much improvement.
Just wondering if someone had already done this before.
Never could see much of a reason to mod that UT01 since it’s pretty nice as is, but the UT02 a lot of people have modded it using same mods as the Manker U21 since they’re the same light basically.
Do you know that the UT01 has a hidden mechanics mode where you can adjust each light level by three individual levels, adjusting the last level as high as it will go will give you about 800 lm’s I think, that’s pretty good for a small light like that, I really do love that light, I think I have maybe 4-5 of them and about 6 or so of the 02’s.
@Boaz, I can’t leave stuff as is, I always gotta try to make it better or make it in to a pile of crap. Its been that way since I was a very young. I was always more interested in taking my remote controlled car apart to see how it worked than I was steering it around the house. :person_facepalming:
@T18, I have 2 of the ut01’s, one I will mod and one that will stay factory or end up as parts for the mod.
I have a Klarus Mi7 ti I modded to 3.7 amps measured at the tail using a modded BLF X6 board running NarsilM with a attiny85 transplant.
It really does make the light super nice to me, especially the UI. The ut01 has a slightly different e-switch board layout inside than the Mi7.
It might be a little more difficult to mod with the BLF X6 board, but probably doable. The UI on the ut01 is not bad at all, so I thought I might just increase the current a little and leave the driver intact. I found the programmable modes while searching for a current mod.
.
I searched google to see if I could find a ut01 that had been current modded but never found a single hit. This light has been around awhile so I was hoping someone had modded the light and just hadn’t posted a write up.
I bought 5 to leave in my family’s cars in the last 2 months. 2 had bad contact between the tailcap and body tube that was resolved by switching the tailcaps around. Otherwise they’ve been great. I’m definitely interested in a driver mod / change if anyone has tried that, I’m not a fan of the long press to off.
Im using the Efest IMR 14500 650mah and I have used the Sanyo cells without issues.
2 of my Efest have button tops and the others are flat top, they all work fine in both lights.
I do have some sanyo protected cells I can try, if that’s what your wondering if works.
I have had a few lights that have to make contact through the cap touching the bottom of the tube.
Most of the time I can clean the bottom of the tube and that solves the problem.
I have also read around here that these lights did have issues with protected or longer cells, cleaning will not fix that.
