It is a physical change. When you supply electricity, the electrons jump to higher energy state. When they come back to their level, it emits energy which falls in the visible region of light. The atoms of the filament (Tungsten) are not going through any change, that changes their chemical properties. Tungsten, still remains tungsten!
Chemical broooooooooooooooo niga
it is a chemical change
Chemical I think
physical as the chemical structure does not change.

No, a metal bar glowing red hot in a fire would be an example of a physical change, not a chemical change.
