Em Ballast

[Alwayslearningelec]

Why would a fixture be required to have an em ballast if it were on an EM circuit( being fed from em distribution..generator etc.)? Shouldn't this only be the case when it is on a normal circuit? THanks.

To cover the time period between loss of power and transfer to the generator?

Thanks USMC. So essentially it is battery back-up.
