Ok I'm at the point of giving up and throwing this flashlight in the bin
It arrived D.O.A turns on for 1 sec -3 sec then turns off on high mode (mid & low work fine)
I changed the driver and it Still has the same problem
I rewired the LED to driver - Still has the same problem
I ran the batteries direct to driver with out switch - Still has the same problem
I re-tested the driver and it looses power at LED so i bought another driver
The other driver has the same problem again!!!
So I bought a 9amp driver from another web site - Still has the same problem
so i did further testing. I re checked the wires to LED make sure that they don't earth out. re soldered a new set of wires to LED to Driver.
Checked voltage while it run for that split second on led and it is 3.54v
then checked voltage on battery before it turns off and is 11.4v then when it turns off battery voltage also turns off.
so tried a new set of batteries- Still has the same problem
then tried non-protective circuit batteries Still has the same problem but voltage drops down to 3.2v instead of 11.5v (must be shorting out)
So i rewired everything again and bench tested it again made sure everything is clear and nothing is touching any-wear - Still has the same problem
I used an external 5amp 11.5v battery system to driver - Still has the same problem
Im thinking that the LED might need more thermal paste under the star?
or LED is Stuffed
what do people think ? i don't know what else to do.. i now have 4 drivers $45 latter and 2 extra sets of batteries and no working torch
PLEASE HELP
