bought the 8x 7135 of this and popped it in my c8

soldered the wires nicely on a 3v sst40

spring burnt its bumhole off and a 7135 turned white

spring got hot . good job i turned it off fast

i even covered the mcpcb with tape so there was not shorts

has anyone else had a DOA driver 17mm

thanks guys

Never had QC problems, the only issue i am aware off is the possibility for jamming the programming feature, as discussed many times by Toykeeper.

The old skool drivers with old FW are extremely robust, have stacked them many times.

Could I just take the 7135s off the back and maybe replace the paint and all would be good

The front 7135/ looked good , I think I have to get my meter out and check

wow this is wierd

i took out the led and tested the voltage on the wires

4.2 volts

maybe my led was a dud

ill try another led when i get one

thanks yokiamy

The 17mm driver Convoy uses in the S2+ with SST40.
It’s a 5A driver.Both springs in the light are bypassed
The 20mm SST driver is 6A
This driver has temperature protection
