Are your lights noisy?



I've noticed that my most powerful light, the Led Lenser M14, emits a high-pitched whine when at full power (it does it at lower powers too, but it's much harder to hear). Once I noticed that, I tried my MT7 with freshly charged batteries, and the whine is there as well, just quieter. It doesn't appear to be a defect, it's just a by-product of the light. :naughty:

So, how about you? Are your lights noisy? Or do I just have very good hearing?? :)
