A) The Wii voltage ranges from 6-12 V depending on the resistance of the bar. It isn't a great power supply.
B) No reasonably priced LED can survive that much voltage with any reasonable current flowing through it. There are resistors in series with the LEDs to drop the voltage to a different level.
C) While it's true that the total voltage across a bar will vary between the Wii and a USB port, the manufacturers of Wii bars know this, and put in weaker resistors to balance this.
D) This means that any bar bought as a USB bar powered by USB should work as well as any bar bought for the Wii powered by the Wii.
E) The only explanations for differences are a poor quality bar (meaning its designers didn't know Ohm's Law/ the specs of their LEDs) or that it's a home converted bar and it's owner didn't know they needed to swap out the resistors.
