DEFT quit last night!
I have only used it off and on since i got it, still using the first set of batteries (energizer lithium, 6.6v on pack).
Switched it on and it came up for a split second and then went out.
Being an electrical guy by trade i did some diagnostic work. I pulled the glue off the inner lens and checked the voltage to the LED. It is the same as the battery pack, ~6.6v with the switch on.
While testing it, if I held the volt meter probe just right the LED would come on...
! kind of blinding.
So, figuring i had a bad soldier joint, and the iron being right there on my work bench, i re flowed the joints on the LED. This appears to have fixed it (whew!).
Now the only lingering thought i have is weather or not any damage has been done to the driver board, if it has one. I have heard that some boards can be hurt if no load is connected.
