Conventional or regular light bulbs are our standard familiar classic Edison light bulb with an incandescent filament. They are the basis of any ceiling light, sconce, floor lamp or table lamp. They glow in , warm light and radiate besides light and heat. In some aspects, they are better in terms of light output compared to modern LEDs. The very construction of the tungsten wire, which emits light and heat, is closer and more natural to the human eye, because it resembles the daylight from the sun.
In addition to the standard incandescent light bulbs, there are energy-saving fluorescent lamps that resemble the standard tungsten lamp in terms of output, but use gas and a chemical process to light. Unlike standard bulbs, they are much more economical, usually spiral-shaped, and are the predecessors of modern LED bulbs. They are extremely suitable for people who are burdened by different light from the natural living room.
