Has anyone noticed a high-pitched or a hissing noise with the LED upgrade for the halogen bulb in the Petzl Duo?
It is something I have noticed, especially when solo caving when everything is ultra quiet.
If you turn the switch slightly, the noise can go, but sometimes it doesn't.
If anybody has noticed this with the LED upgrade, please let me know - otherwise I will be thinking it is my usual perennial bad luck when buying new things.
