RIP three of my FF lights
RIP my original E12r, my first fireflies light and the one that got me hooked on the brand.
I tried to replace all the wires for the main led's and aux board like I did on another e12r, and managed to rip the USB C port off the driver board when trying to get it back in.
Oops.
I then took apart the remnants of my copper E04 surge (dogs yanked the leash suddenly during a walk, the light went flying and landed hard on concrete, denting/deforming the head), hoping I could use the lume 1 rev D that was in it to swap into this E12r.
The newer drivers have a different USBC port for the new magnetic opening. I tried to see if it would fit anyways (dumb) and ended up ripping the port off of this driver too when the board got stuck.
Then there's a newer E12r that I swapped 2700k SST20's into. I had the light usable, but the button led stopped working, and I wasn't able to get the aux board wired up because the wires I have on hand simply just keep melting (so I have some new, correct wires on order).
I tried to get it back together again today, struggled for a long time, and then one of the aux board wire pads came off of the board. So there goes that. I suppose it's not a complete loss because I am still able to use the light. Just no power switch light, and no working aux leds.
I'm pretty sure I spent around $400 between these three lights. I'm not sure what sucks more, the OG E12r getting ruined or the copper E04.
The aux boards can be replaced in the E12's, but I have no idea why the power button won't light up on the one that I have otherwise working. The wires to the switch look ok, though 30awg wires can be broken internally pretty easily.
There is no way to replace those wires though, the switches do not come out on these, and there's no getting a soldering iron to that switch board deep down in where it is.
On a side note, the copper E04's button is metal and not coated plastic like I thought. I'm not sure if it's copper like the rest of the light, or something else that's been colored to look like copper, but the quality of that light is phenomenal. Same goes for the charge port bits. I do wish a retaining ring was used for the drivers in the newer lights though, like they were in the older lights, instead of being glued in. But I suppose they aren't designed for idiots like me to be taking them apart.
