Hi, the flashlight worked well after some years, but yesterday I had the unfortunate idea to clean it externally with a damp cotton swab. The flashlight gave me problems immediately. Now when I turn on the flashlight, every 2-3 seconds it dims the light intensity and then turns off automatically. I just opened it without disassembling anything and dried internally with the hair dryer, but I'm getting the same problem. I am not an expert but I love that flashlight. What can I do to make it work? It seems unbelievable to me that it got ruined like this. If it is not possible to repair it, can you tell me if there is a similar flashlight, with the same power or better? Many thanks for your welcome advice.
