I bought this light as a back up/warning lights for times I work on the accident scene, kayaking and biking. I read about some problems that gentlemen from LED museum experienced with this light but they didn’t seem that concerned with it and they are experts so why should I be. I didn’t even put this light thru any abuse yet. No rough biking or crazy kayaking stuff. During EMT work it was worn on my belt so not much shock and bumps were happening there. All of the sudden the white LED portion of the light failed. I took the battery in and out to play around and maybe "reset" the circuits but it didn't help. Oh well gotta send it back. I just hate when equipment malfunctions in the field for no apparent reason.
