If you plan to use this outside of the US with a 240v power supply you should think twice. I ordered one and it started blinking on its own. The trigger was off, the overhead lights were off, just kept firing for no reason. Eventually the fuse blew, and every time I replaced the fuse it immediately flashed and the new fuse blew. So I returned it (Revain is great for returns) and got another one - SAME. Too bad because it's a damn nice light, but now I have to find something else.
