Lexel, good point. I am still learning about this so let me see if I understand it correctly: using 19V on a 24V setup will increase the current thought the Leds (as the resistance will not change) causing the tint shift, right? What would happen with the opposite? Powering a 24V with 30V for example. The current would decrease? and it would also cause color tint shift?
Let me ask you something about the tint shift in another situation if I wanted a really low output from these lights (I know I can always use PWM at the stated voltage, but for the sake of theory): what happened if I power a 12V led strip with a 5V powerbank? The current would increase until the USB reach its max current. And that is probably too low. These leds would run with less current, would they also have tint shift (or would they turn on at all)?
The second situation would be the follolwing: powering a 12V led strip with a limited current 12V power supply. The leds would be less bright and less color accurate?
Thanks
