I love this light and have made strong to ridiculously forceful efforts to get the MCPCB out and it will not budge. One can see the damage from probes, flat screwdrivers, needle nose pliers…
I did solder in a BLF A6 A17DD, so I’m ready for the LED upgrade!
I found this thread for the A6 driver and SFT-40s: BLF A6 A17DD driver okay for SFT-40?
