in a compact flourescent about 8mg.
it all depends on the voltage the light bulb can sustain.
The light bulb. The light bulb. The light bulb.
The function of a light bulb in an electric circuit is that it turns electrical energy into light.
Efficiency is typically associated with minimizing losses in a circuit. If you have no load you couldn't compute efficiency. If there is a load you need to determine what you are trying to measure. For example, in an incandescent light bulb a lot of power is wasted in heat. So if light is what you are looking for an incandescent bulb isn't very efficient. A compact fluorescent would be more efficient. However, if you were using a light bulb to power an "Easy Bake" oven it would be more efficient.
EEdmund Germer (90% sure) made the first fluorescent light bulb
The energy saving light-bulbs are usually fluorescent. Neon is a type of fluorescent light bulb.

fluorescent light bulbs are usually from 9$-15$.
The flourescent light bulb was invented in 1827.
The long thin light bulb is called a fluorescent tube or a fluorescent light bulb. It is commonly used in commercial buildings, offices, and schools for general lighting purposes.
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.
By far the hottest of the two light sources is the light bulb.

The light-producing element in a fluorescent bulb is mercury vapor. When electricity passes through the gas, it emits ultraviolet light that then excites the phosphor coating inside the bulb, causing it to emit visible light.
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.
Fluorescent light bulbs use phosphors to convert ultraviolet light into visible light.
