Let's determine the energy transformation of a light bulb.
A light bulb can be said to be a device which has an electrial filament of LED that is enclosed in a transparent shell and produces light when energized.
In a light bulb the flow of the charge through it causes the light bulb to produce light and heat up.
Therefore, since it produces light and heat up when current flows throug it, we can say the light bulb converts electrical energy to light and heat energy.
ANSWER:
The light bulb converts electrical energy to light and heat energy.
