The second one is Incandescent Lamps, were mostly used in past and getting replaced by Halogen bulbs. It has a filament inside the glass. These types of bulbs produce great amount of heat but result in very little light. This means more energy is being wasted, hence is phased out for more efficient bulbs.
The last one is Halogen bulb, which is quite popular and uses an incandescent bulb, but utilizes the heat greatly and outshines every other bulb type.
