[APD] working 115V lighting fixture in 220-240VAC region

Dear all,
I just received confirmation from a leading aquarium lighting fixture
manufacture that their 115V, 60Hz fixture will not work with 50Hz.  In
other words even though you step down your local voltage to 115VAC, the
fixture still can't work because it is design to intake 60Hz rather than
50Hz mains supply.
How do you see this?

This is my understanding as well.
