Brynnl S11 (similar to Seeknite S11 ) and Nitecore Tini received 219b 4500k upgrades
Nitecore Tini emitter swap looks daunting but it’s pretty simple reflow procedure using SMD Hot air gun ( I used cheap CO-Z brand). I heated the surrounding area avoiding direct heat on the led. The trickiest part for me is disassembly/reassembly. It needs Hex 0.9 bit for 6 screws.
Components are pushed out on the USB port hole side in the plastic housing. The white stuff is thermal paste on small heatspreader.
Brynnl S11 just needs to be pushed/pulled upwards from the body. I used the usb port. The led could be reflowed with heat gun but I de-soldered the pcb and used a hot place
