Incandescent light bulbs contain a metal filament (normally tungsten). When electricity flows through the filament, it gets very hot, causing it to emit light. They are inefficient because most of the electric power goes into heat. Fluorescent light bulbs contain a circuit that increases the voltage of the electricity, which then ionizes Mercury vapor. This ionized mercury emits ultraviolet light, which causes a coating on the inside of the glass bulb to glow ("fluoresce). They are more efficient, but many emit an ugly color of light.

What is the difference between halogen and incandescent bulbs?
Halogen light bulbs are what has been around for a very long time. Incandescent bulbs are new and are more energy efficient.
What is the difference between halogen and incandescent lighting?
Halogen lighting is more energy-efficient and produces a brighter, whiter light compared to incandescent lighting. Halogen bulbs also have a longer lifespan and are more expensive than incandescent bulbs.
Energy saving lamp LED or CFL bulbs are being used in cars and even in heavy vehicles are they comparable with the old incandescent bulbs in terms of luminance?
LED, CFL and incandescent, when compared in terms of luminance, LED beats both of them. The range of difference between LED and incandescent are very big, whereas CFL comes in between them.
What is the difference between incandescent and halogen lighting?
Incandescent lighting uses a filament that heats up to produce light, while halogen lighting uses a tungsten filament surrounded by a halogen gas to increase efficiency and lifespan.
Difference between of natural and artificial sources of light?
The difference between natural and artificial sources of light is that natural sources are produced by the sun while artificial light sources illuminate using energy from other sources and include incandescent bulbs.
What is the difference in fluorescence between incandescent light bulbs and fluorescent light bulbs?
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.
What is the difference between the led bulb and incandescent bulb?
Incandescent: 10-12 lumens per wattHalogen: 15 lumens per wattCFL: 50 lumens per wattLEDS: 50-60 lumens per watt in bulbs you can buy in a store, but some manufacturers have claimed more than twice that. sheerled.co.uk/
What the different between candescent and incandescent?
Well, sweetheart, the only difference between "candescent" and "incandescent" is the letter "in" at the beginning. "Incandescent" refers to something emitting light as a result of being heated, like a good ol' light bulb. "Candescent" is just a fancy way of saying something is glowing or shining brightly. So, there you have it, two words with a slight twist in meaning.
What is the percentage of light output between CFL bulbs and an incandescent bulb?
Incandescent: 10-12 lumens per watt CFL: 50 lumens per watt.
What are the differences between fluorescent and incandescent lighting?
Fluorescent lighting uses gas and phosphor coating to produce light, while incandescent lighting uses a filament that heats up to produce light. Fluorescent lights are more energy-efficient and last longer than incandescent lights, but incandescent lights have a warmer color temperature.
What are the differences between fluorescent light and incandescent light sources?
Fluorescent lights use gas and phosphor coating to produce light, while incandescent lights use a filament that heats up to produce light. Fluorescent lights are more energy-efficient and last longer than incandescent lights, but incandescent lights have a warmer color temperature.
Between fluorescent and incandescent which saves electricity?
Fluorescent lamps deliver more visible light than incandescent lamps using electric power at the same rate. (But incandescent lamps deliver more heat. Just depends on what purpose you're using light bulbs for.)
