LUV my UT02 , Now hav a bit more power 5 amps and now a E2 3C LED

Just luv the UT02, but would like a bit more throw, just so it out performs the P30

lets here about some of your mods , R100 or R050 or Driver mods or change that xhp35 for something else ??

this is a great torch and i think it deserves a dedicated modding thread , please Kawiboy and Giorgoskok tell us about some driver mods

cheers dave

I have tried adding a R050 over the existing resistors , for a ~30% increase in lumens . I can’t remember exact measurements .

I think Mitko has done extensive testing on modding the Ut02/U21 driver .

I have also tried more mods for my Ut02 , but they require a different driver :

fet driver and xpl hi v3 for 180-190kcd

fet driver and dedomed xp-g2 for 290-300kcd (900-1000 lumens)

few weeks ago I received my UT02 CW (1A ordered, but in my opinion is a 1C), even on my I measured only about 2.4A at the tail-cap.
Last weekend I replaced the original resistor R05 with a R01 getting 5.6A, but with only two brightness levels, so I replaced it with a R018 getting 5,4A and 1390 lumens and with all levels perfectly functioning.
Then I did the bypass spring and I got 5.6A and 1,450 lumens.
Now I am very happy with this little thrower , I hope the driver resist.

sorry for my bad english

I tried to replicate this mod but that little resistor was beyond my skilset Wink

Hello, just add r100 to the driver and get about 119000 cd in nw verison with liitokalas 26650 fully charged

I’ve been ondering if there are any weak link components on the origional driver that could be upgraded to reduce the risks of resistor modding? Mitko had a diode blow on one of the early manker models. I tried to prove for more information but was never replied to.

You can upgrade the inductor, the FET, the diode and then do a resistor mod.
That reminds me of the mod i was doing on the MT03… Should pick that up again soon.

If you change the diode and do the resistor mod it should be good to go for years .

It’s better to pot the driver too.

What diode needs to be changed?

You can change the large diode for a low Vf Schottky diode.
You can gain around 0.3 mV that way, but probably not that important for a driver that boosts the Voltage up to 400%
More important for 2× 18650 buck driver for a 6 Volts LED.

hav put a 075 resistor on top of the shunt and now pulling 5 amps , heaps better and was Very easy to do

Now i just want to go a bit cooler than NW , Can U guys recommend a better xhp 35 maybe around 6000 tint ?

These are really nice de-domed if your up to the challenge? Wink

5amps is too much for XHP35?

im yet to mod mine and im very tempting.

do you have any issues after the mod?

UT02 uses a boost driver , 10fp says 5amps draw from the battery Thumbs Up

I love the UT02 as a host. The (old school) XP-G2 de-domed was one of my favorites!

Pulling over 6amps and throwing over 300kcd it was a laser beam jacket pocket rocket thrower!

But for a Bombastic Boomer I use the XHP70.2 UT02 the most. With the Lexel built T/A Narsil driver, copper driver adapter’s, I then bored the head out for a 32mm Maxtoch board, used a Convoy L6 white switch boot and wired off the driver, with resistors, lighted up the stock e-switch, blue or red, but I liked the red only, for DANGER! Big Smile

The 70.2 P2 1A at 8+ amps is quite impressive out of this smaller light, nice over all beam with a large Hot spot with this smooth reflector. Wink

Ask Simon for them, the L6 tail cap white/clear boot.

I like the P2-1A the best so far, less of a brown/yellow corona, ring, then say the B-C’ I have tried. The beam is white, not cold blue-ish, like the P2-1C as is the ample spill. The beam is naturally big, coming out of a short reflector, but it lights up the neighbor across the street back yard/driveway like daylight so it has decent trow for a small reflector. It would make for a nice patrol light, even say half way up the ramp it is more than enough light, but then double click for Turbo, yeah there’s no where to hide!

I’m looking at getting a couple more of these UT02’s if I can find them for the $28-$30 price I got the last 4 at? I found some interesting other 70.2’s at Mouser I want to try out. They describe them as a white/white 5700k and a white/warm 5700k? They are P2 bin but 0E and 40E?

Where’s the best place to find these resistors? They are 0603 resistors correct?

is your UT02 NW or CW ? and hav u modded the resistor yet ? how many amps at tail ?
mine was NW and that was considerably cooler than the MF02 in NW . the MF02 seems more like 4000 so it will def get a E2 3C

pls post your before and after figures when youv checked them
