My Preon is mute too. I guess It'll have to communicate to me with morse code. 😉

"Thanks for contacting us. The whine you are noticing is the standard
"inductor whine" present with all high-end LEDs; if it were possible
to get you a light without this, we would be more than happy to
exchange that for you, but this is present on all the Preon lights."
If this whine is standard on all "High End" LED'S how come your two do not have it; nor does my Illuminati? (Or other lights I have ordered). I have shown my Preon to a number of people and all that agree whine is quite loud. No point in replacing it or ordering another Preon if this is "Standard".

i used some fine rubbing compound for mobile phone displays on the threads of my preon. it took some hours, but now the threads are perfectly smooth.
I did the same on my brothers preon1 ti, only i used turtle-wax heavy duty car rubbing on it, (only rubbing compound i got left) and it turned out pretty smooth after 15 min.
No one ever told me that the Preon would be addictive. I just spent about 30 minutes looking all over my apartment...trying to find my misplaced Preon 2 Ti. Turns out it was hiding inside my pillow.(I think I'm growing attached to this little wonder...)
If that isn't a sign of a flashoholic...I don't know..

My Preon II black titanium edition was silent for about a week, but now has the whine on low and really loud on medium setting, and silent on full brightness.
It's annoying, I might have to send it back...
Same with mine, except ti Preon I. Hoping it goes away the same way it came ... spontaneously. I'll stick with mine regardless.
Also, is it safe to use NiMH Rechargable AAA's in the light?
The clicky feels great to me, and im not sure if they changed it, but I only have to soft click it to move to the next level.
