iTP A3 - Vibrating?

[Wiggle]

My ITP A3 seems to noticeably vibrate. Moreso on medium, a little on low and not at all on high. I'm sure it's related to the PWM circuit somehow. Has anyone else had this problem? Should I send it in under warranty?

You should be very happy.

Did that cost extra ?

But, you received with this issue or arrived perfectly and in some time it began to do that?

I have one and not vibrate, nor the flashlight itself nor the light beam.

Probably defective

It's the pwm at work.
Totally normal.
Assuming your talking about the light output.

Here's ITP A3 on top and Quark mini or ITP A2 on bottom.

Lucky you.

Never had any type of light do that,had a couple small issues with my A1 but my A3 has been fine.

That sounds like an inductor issue.... the little piece of metal inside it is thwacking around.

I mean the light body is physically vibrating.

Uh oh, it's getting worse, its got loud buzzing now and in low it flickers and then defaults to high. Think I'll have to send this in.

Yes that sounds like it has to be some loose coil or other parts.

Yep, that's what I was saying. The inductor core comes loose and thwacks around with the magnetic currents. The longer you leave it on, the more it breaks apart the inductor casing and the more freedom of movement it has. The inductor has to be replaced, there's nothing you can do about it.
