Hi all,
I have a H501R (red emitter) which worked fine so far.
Suddenly it stopped working : did not light up at all. It has not fallen down, no shock, no water, nothing special.
So I cleaned the contacts, and put it a fully charged NiMH : worked again sometimes, but with an erratic behaviour.
Tried a fresh primary Alkaline : again erratic behaviour. Same with a fresh primary Lithium.
What I call "erratic behaviour" is:
It doesn't seem to be correlated with the battery type (NiMH, Alkaline, Lithium), i.e. I can see different behaviours with one given battery type, or the same behaviour with different battery types.
Thanks in advance for your suggestions.

What I call "erratic behaviour" is:
- Sometimes after the battery change I see the very short and bright usual flash when tightening the tailcap, and then it works normally.
- On other battery changes the LED will turn on permanently but very faint. Any action on the switch (either short or long click) does not turn out the LED, I need to unscrew the tailcap to make it go off.
- Sometimes on battery change the LED glows dim for a fraction of a second, then turns off. One click will turn it on again for a few seconds (very dim) then out.
- Sometimes it will not turn on at all, I don't even see the initial brief flash.
