The main difference is how light is produced in each. In a LED, a device known as a light-emitting diode produces light when receiving a certain level of current. In an incandescent bulb, a thin piece of conductive metal glows brightly (incandesces) when subjected to a current in an oxygen free environment, such as a vacuum or near-vacuum (the absence of oxygen keeps the metal from burning and decomposing). Finally, a fluorescent bulb works by subjecting a special mixture of gases to an electric current. The current excites molecules of gas, which release light in the process.
Heat.
There is no difference. CFL is an abbreviation for Compact Fluorescent Light which has simply been designed to take up less space than the standard tubes.
Fluorescent bulbs generate light by using an ionized gas and electrical discharge, whereas regular light bulbs generate light by using heat within the filament contained in the bulb.
a normal light bulb gives off more light
no
"Normal" light globes use a glowing filament, heated by the current. Flourescent tubes ignite a gas within a tube, using an arc.
Heat.
No. You must begin with fluorescent pigment.

Luminescent materials emit light without needing an external light source, while fluorescent materials absorb light and then emit it back at a different wavelength.
Yes.Blue light that is given off disproportionately by video monitors and fluorescent light can disrupt the normal sleep/ wake cycles and make it hard to sleep at night.
Fluorescent materials absorb and emit light almost instantly, while phosphorescent materials absorb and emit light with a delay, continuing to glow after the light source is removed.
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 bulbs generate light by using an ionized gas and electrical discharge, whereas regular light bulbs generate light by using heat within the filament contained in the bulb.
Phosphorescent materials continue to emit light after the excitation source is removed, while fluorescent materials only emit light while the excitation source is present.
Fluorescent light is a type of artificial light created by passing an electrical current through mercury vapor to produce ultraviolet light, which then excites a phosphor coating on the bulb to emit visible light. Natural light, on the other hand, comes from the sun and contains a full spectrum of colors. Fluorescent light tends to have a bluish or greenish tone and can cause flickering, while natural light is more consistent and beneficial for human well-being.
Fluorescent light bulbs produce light by converting ultraviolet radiation into visible light through a process called fluorescence. Incandescent light bulbs, on the other hand, produce light by heating a filament until it glows. The main difference in fluorescence between the two types of bulbs is the method by which they generate light.
