Can you clarify those two points for me? I can understand not
undersizing the transformer, but don't understand why oversizing it

And the second assertion doesn't quite make sense to me, either.

According to the Malibu instructions, "as the load decreases on the
transformer,
the voltage increases. Therefore, the life of the lamps will be reduced
unless
the transformer is carrying close to its rated capacity."


Ah, an unregulated power transformer. I'll remember not to buy Malibu.
