I just received my UT02. What is the “breath flash” suppose to do? It is found after the strobe and all I see is the indicator light changing from red to purple. Does it do something else? Does it have any meaning?
I tried one of mine very briefly and it worked. The only 26650 that I couldn’t get to work was the Klarus battery that comes with the G20 (button top). I also had trouble with a button top protected Keeppower 18650. Everything else worked, which were flat top or semi-flat tops.
I’ll try and generalize things, correct me if I’m wrong.
If I buy a UT02 now, it will probably only be 2.5 amp at the battery and deliver 40% to 60% below specs. So non modders should steer clear.
The modders can add a R050 to R100 and boost the power back up to stock levels (1300lm)
If this resistor mod causes the drivers to break, the lights can then be used as hosts. An xpl hi and a buck driver can be installed and you can get above spec output (1500lm).
Does this sound about right?
If so, I might get me one just for the heck of it.
Yes, you are correct. Tom’s driver picture is from a Manker. I was thinking it was from the weaker Utorch.
After comparing the battery loads I can see that all modes, besides low, have been shifted down. They no doubt changed the firmware to maintain good spacing. Costs them nothing as well.
Turbo is 55% less
High is 47% less
Mid 2 is 39% less
Mid 1 is 20% less
How has your light with the added R050 resistor held up? Still working good?
