I think it’s more to do with the reflector shape and focus than the led type. You can try adding a paper spacer under the centering ring to change the focus slightly.
I dont know if this is a common thing with the FT03 mini 50.2.
Received mine today with the SS bezel. Overall it's impressive. Mine is the 5000K SST-40, might be my first 5000K SST-40, and I do like this LED's tint and beam in this light.
The AUX LED setup is a bit confusing but I think I understand what's going on. Besides the switch LED, there are 4 separate LED SMD's around the main LED and they cycle through 6 patterns of:
RED, RED/GREEN, GREEN, GREEN/BLUE, BLUE, BLUE/RED (no white as the manual says)
You can't stop the cycling, can't select a separate color and have it stick. The reason is it doesn't work like an Emisar light is because it's using the ATTiny85 MCU, not the 1634, and therefore doesn't have the I/O pins or memory to control that many LED's. The AUX LED blinking is probably controlled by the add-on AUX LED board, assuming it's a Lexel design (?).
You can't even stop the switch LED from blinking, so maybe there's a firmware mod as well? Dunno, I find it annoying - only option to stop it is by turning it all off.
Ooops! My Bad! 6 clicks plus click/hold toggles through solid color choices.
I see this behavior in some other flashlights (some Sofirn, like SP32A or SP31v2.0 and also sometimes on the Convoy S2+ with XPL-Hi).
I haven’t gotten the FT03-Mini XHP50.2 yet so I can’t check.
I’ll need to double-check other XHP50.2 flashlights (SP33v2, SP33v3 or Convoy S11) to see if they also have this “yellow spot” in the center of the hotspot…

That’s strange. Like Funtastic mentioned, mine can also cycle the Aux LED colors or choose 1 color (or even the “Voltage” indicator color), much like the aux-LEDs of the Emisar D4v2.
There’s nothing unique about the centering ring, doesn’t do any centering, the screws are holding everything centered, it’s just insulating the reflector
I honestly don’t know what Tom is talking about because I can change colors and have it save.
From manual
“Note: The button led wire is connected with green, so it will be on when aux led colors include green like yellow, green, cyan, white. The button led will be off when aux led colors are red, purple, blue.”
Tom, the button will only flash if you have it cycling the colors. Can you not change the colors at all? I do 6 clicks + click hold and it cycles through colors, release on the color you want, if the aux led flashes and you release, then it selects the cycling again.
