The Convoy SS bezel fits on the Sofirn C8F. These lighted switches will not fit as the switch PCB on the C8F is 23mm. I made a picture of the switch assembly in my review here: REVIEW: Sofirn C8F 21700 (comparison, beamshots, teardown PIC HEAVY)[21700, 3x XP-L HD, C8 format]
The Sw45k leds will have a nice tint but maybe only an estimated 1500-2000 lumens.
Recently I mounted three 6V 90CRI XHP50.2 with the Convoy M21C-U boost driver. Looks and works nicely. I will also put some Luxeon MZ leds in another C8F and see if I get a donut hole in the beam. However, these mods involve a bit of work.
I would not recommend XPL2 leds in the C8F because of the tint shift. The LH351D leds should be nice, they are quite rosy when dedomed.
