At temperatures around 2000 k the filament starts to emit visible light. The higher the temperature the shorter the wavelength of the peak. Page 5 incandescent bulb. The peak of this radiation corresponds to a temperature of about 2 7 degrees kelvin.

An incandescent light bulb contains a tungsten filament that is resistively heated when a current is conducted through it. An incandescent bulb has the whole electromagnetic spectrum as it is the light from a hot object but the fluorescent bulb creates an emission spectrum as it is the emission from the secondary fluorescent material.
