I have had my m6 for about a month now at tops. With The first set of batts I got with my m6 I blew my 500 lumen bulb. Bad luck? Well, yesterday On my second set of batteries which were surefire brand, my 250 lumen bulb melted/exploded, fusing glass to my bezel. Now I have a basically brand new flashlight that has to be sent back for repair and two wasted bulbs. Is this typical of the m6? I have had an m3 for over a year now and haven't even had to replace a bulb yet. Not trying to rag SF I LOVE the light output and HIGH quality machining of these flashlights, but form should follow function.
