It barely depends on the load type
in resistive load the heating and lighting effect is reduced.

In Inductive type the magnetic field strength will be decreased

In capacitive load the voltage will be maintain due to surge voltage for define time period

But the first two type load the load may be burn due to drawn of the excessive current.
