L2, L1, A2 Surefires with low and high beams noise

cslinger · Mar 18, 2005

I realize that it is a known quirk of the L2 that on low if you listen closely you can hear a high pitched whine from the electronics. My A2 actually does this as well.

I just wanted to confirm with other users that this is simply a quirk and in no way has damaged anybody's lights.

Thanks so much,

Chris

It is a "quirk".

The L2's I've seen (including my own) do this on low but I can't hear anything on high (unless I remove the bezel).

It has in no way damaged anybody's lights.

Where would this oscillation occur?

Neither of my L1's produce noise in either low or high mode. My A2 produces a barely discernible (I have to be holding it right up to my ear) noise in high mode.

1 L1 (old type): no noise either level
1 A2 (new 3-sided body): no noise either level.

I guess I will have to buy an L2 to see if it makes a noise. That's as good a reason as any, right?

<sweeping generalization here, folks>

The hum/buzz/whine/noise typically comes from the electronics board(s). Usually it is "inductor sing". Anything with an electronics board in it -may- make noise.

Usually the noise is just a quirk and is nothing to get worried about.

I wouldn't know as the guy I bought my L1 off of on Ebay has not replied to me regarding shipment of the light yet!

My A2 doesn't make any noise that I can hear. .

I finally got that L2 I have been wanting.

It has the whine on low, barely audible.

It seems to be comming from the tailcap though. It is loudest there, but I can also hear the noise faintly at the head. When I press the button a certain way, the noise goes away completely (as far as I can hear).
