The energy saving light-bulbs are usually fluorescent. Neon is a type of fluorescent light bulb.
In a compact fluorescent light bulb, electrical energy is transformed into light energy through the excitation of mercury vapor atoms inside the bulb. Some electrical energy is also transformed into heat energy due to resistance in the bulb's circuitry and the phosphor coating on the bulb.

A light bulb is an output device. It receives electrical energy and converts it into light energy.
A light bulb is an output device because it produces light when electricity is applied to it. It takes the input of electrical energy and converts it into light energy.
A fluorescent light bulb contains a gas which produces UV light when it comes in contact with electricity. Contrary to a normal light bulb this does not create any heat and is far more energy efficient.
The swirly light bulb is called a compact fluorescent lamp (CFL). It is a type of energy-efficient light bulb that produces light by using electricity to excite the gas inside the bulb to create illumination.
The element in a fluorescent light bulb that absorbs UV light and releases visible light energy is a phosphor coating on the interior surface of the bulb. When UV light hits the phosphor coating, it emits visible light, creating the illumination we see in fluorescent bulbs.
Incandescent and halogen light bulbs use more energy than compact fluorescent lights and LED lights. Fluorescent lamps with magnetic ballasts use more energy than fluorescent lamps with electronic ballasts.
Fluorescent light bulbs are typically more energy-efficient and produce more light for the same amount of power compared to incandescent bulbs. So, a fluorescent light bulb may appear brighter than an incandescent bulb with the same power rating.
They are called CFL light bulbs. CFL stands for Compact Fluorescent Light .
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
