ledSet[1].writeSpeed(50); // Sets the speed of fade to 10ms per increment <<<<<<<<<<<<
ledSet[0].write(0);

change the speed on object one and then dim object zero...?

try:

ledSet[0].writeSpeed(50); // Sets the speed of fade to 10ms per increment <<<<<<<<<<<<
ledSet[0].write(0);

there are two fade objects to manipulate 0 and 1.

Got it?
