This particular unit of the Sofirn C8T seems to act strangely.

It's supposed to be neutral-white tint (5350-5750K, as per Sofirn's specs for the flashlight).

When switch on at Low mode and Medium mode, the tint appears to be "neutral-white" (5350-5750K), but when switch to the Highest mode, the tint turns bluish. What could be the problem?

(also I think I see some wisps of smoke inside the flashlight's head/reflector when on Highest mode)

(my camera doesn't have manual setting for aperture size nor shutter speed, so it's manually compensating the brightness for the photos below):

On LOW brightness:

On MEDIUM brightness:

On Highest brightness:

MCPCB cannot handle the heat , most probably poor thermal path. Heat will kill the emitter if you continue to use it on high. Need to dismantle to troubleshoot.
