Yes. All light is electromagnetic in nature.

Yes they are all electromagnetic in nature. The normal bulb is a tungsten element that is glowing red hot so it emits a white light with all wavelengths of the electromagnetic specturm. The tube light does not emit all wavelengths of the electromagntic specturm just more narrow. How can you prove this you ask? Well take a prism and watch it break up the lights. Your eyes can see the visible spectrum red, orange, yellow, green, blue violent. Below the red comes infrared and past the violet is ultra-violet. You can place a thermomemeter on at various intervals and measure the temperature. If you placed the thermometer after the red you would also measure a temperature. Or past the violet you would measure a temperature. There is energy there but your eyes cannot see past a certain wavelength.

All visible light, even microwaves, x-rays, radio waves, and gamma rays are forms of electromagnetic radiation. They all have a characteristic electric field and magnetic field (which are both normal/perpendicular to the direction of propagation) that depend on the frequency and wavelength of the emitted light.
Visible light has a wavelength of about 400 nm (nanometers) to 700 nm.

All light, regardless of its source, is electromagnetic in nature. For proof, stop by my house and I'll run an experiment for you : 0

By measuring the frequency and wavelength of light emitted by house hold bulbs and tube lights, it has been already proved that they are electro magnetic radiations.
Frequency and wavelength are the main characteristics of electro magnetic radiations.The veocity of these lights can also be measured using special experiments by measurig the refractiv
e index in a medium like glass.
They do confirm that these rays are E.M radiations.

By definition light is electromagnetic waves just like radio waves, radar waves gamma rays and so on...
