Blackburn Flea lights
 

Anyone have any experience with these? I bought one last summer and it would
work fine for several hours in its flashing mode. Now that weather has
dropped below freezing, however, it runs for only about 15 minutes before
shutting off; in other words, I cannot get home with the damn thing still
working. I had been as careful as I could to fully discharge it and then
charge it fully, but that does not seem to have helped.

Temperature effects battery output, see:

This might be your problem if your bike/batteries are kept at outside
temperatures. In cold weather.

Try taking the light (and battery) off the bike and keeping it in a
warm location to see whether that lengthens the life a bit. that
should help identify the problem.

I'm a Canadian and a soldier who is trained in winter warfare. I know well
the effect of temperature on batteries, especially rechargeable ones. I
just hadn't expected it to be so severe. I suspect that the Flea, with its
tiny battery, is particularly vulnerable.

The light and battery are a single sealed unit that is always indoors when
it is not in use. I have cleaned the contacts on the charger and the light
and recharged it again after letting it go flat. I'll see if that helps.

I have the USB version of these lights for front and back. About 6
months after purchase, the front one started to shutoff after a few
minutes. I took it back to the LBS where I purchased it and received a
replacement.

They said it was likely stuck in Demo mode. After trying to reset the
demo mode they replaced it without question. Most Blackburn equipment
has a lifetime warranty.
