Last night I did a "bump" test of my SureFire belt carried white light. I found that the batteries were virtually dead. All I could get out of the lamp was a dull glow. A bump test is my own invention. What I do is "bump" the thumb switch to get a flash out of the lamp. I do this maybe every couple of weeks or so once I begin to question how close the current battery set is to providing the rated 60 minutes of illumination.
The last test I did was last week and the lamp illuminated though I don't know how powerfully. All I did was see that when pointed at my hand I could see the illumination in broad daylight.
This suggests to me that the SureFire maintains a very bright light right up until the end when it suddenly goes dim.
Does anyone know of some sign the SureFire may exhibit when the battery set is about to fail?
I think that what I will do in the future is just simply replace the batteries when I think I have racked up say thirty minutes of illumination. I'll keep the old batteries, though, to use in training exercises.
