Forgive me if this has been discussed before ,my internet connection is too slow at the moment to search.
I bought a Chinese led headlamp that takes 18650 batteries it also makes a high pitched noise on medium brightness I noticed after wearing it for awhile (with a hat on) that my forehead felt a bit painful where the lamp was sitting, almost like my forehead was "burnt" but there is no red marks, that feeling lasted about 3 weeks or more so it wasn't from being too tight etc. .
I was thinking maybe the Led lamp got hot and burnt my head but I put the led headlamp on again at a later date making sure that it would not touch my skin or get hot and now I have the same burning sensation on my forehead and I know for sure that it never got too hot to burn me. I knew something wasn't quite right so i did some research and found that some cheap led headlamps may have crappy power supplies that put out a lot of EM radiation (especially on the medium brightness setting) I think that the EM radiation from this led lamp May have caused this to happen to my forehead!
I found this video as well.. https://www.youtube.com/watch?v=15d-3enuc2k
My question is did I get a dose of electromagnetic radiation to cause my forehead to burn or am i just being paranoid thoughts?
