Depends on the colour of the coating, the tint can go anywhere. The green coating of my D80V2 actually works as a minus-green filter, a purple coating removes some red and bluecand so effectively makes the tint a bit greener. I have not seen red or orange coatings (apart from non-functional coatings on very cheap chinese binoculars), those would make a tint cooler.
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.
