LEDs are solid-state lights that use light-emitting diodes as the source of light. They are semiconductors that glow when electricity is applied to it.
The efficancy of LED package & products depends on many factors, which range from electrical effciency to internal quantum efficiency to spectral efficiency.

What else can I help you with?
When a fluorescent light bulb glows what state of matter is it?
it is plasma , gas and liquid
Can you put a black light bulb in any fluorescent fixture?
Yes a black lamp tube will work in a fluorescent fixture. Guess you don't remember the early 70's.
What advantages do fluorescent tubes have over incandescent bulbs?
Fluorescent tubes last longer and supply more light per watt of energy consumed than an incandescent bulb.
How much money do you save by using a 20 Watt Compact Fluorescent over an incandescent bulb?
An Energy Star qualified compact fluorescent light bulb can save you around $30 over it's lifetime, paying for its self in about 6 months.
Should the government make a law that requires all people to use compact fluorescent light bulb for the common good?
no
How can one accurately measure the brightness and efficiency of fluorescent bulbs?
To accurately measure the brightness and efficiency of fluorescent bulbs, one can use a device called a light meter to measure the amount of light emitted by the bulb in lumens. The efficiency of the bulb can be calculated by dividing the number of lumens produced by the amount of power consumed in watts. This will give you a measure of how effectively the bulb is converting electricity into light.
Who invented fluorescent light bulb?
EEdmund Germer (90% sure) made the first fluorescent light bulb
Why is mercury in fluorescent bulbs?
Mercury is used in fluorescent bulbs as it helps produce ultraviolet light when electricity passes through the bulb. This UV light excites phosphor coating inside the bulb, which then emits visible light. While the amount of mercury used in fluorescent bulbs is small, it is essential for their function and energy efficiency.
What are the differences between an incandescent bulb and a fluorescent bulb in terms of energy efficiency and lifespan?
An incandescent bulb is less energy efficient than a fluorescent bulb because it produces more heat than light, wasting energy. Fluorescent bulbs are more energy efficient as they produce less heat and more light. Additionally, fluorescent bulbs have a longer lifespan than incandescent bulbs, lasting up to 10 times longer.
When was the fluorescent light bulb invented?
1857
What type of light is 20w energy saving bulb Halogen Indandecent neon fluorescent etc please help?
The energy saving light-bulbs are usually fluorescent. Neon is a type of fluorescent light bulb.
How much is a fluorescent bulb?
fluorescent light bulbs are usually from 9$-15$.
Where is there a resister in a light bulb circuit?
In an old-fashioned light bulb, the part that emits light is a resistance. When current flows through it, it heats up so much that it glows - it emits light.Due to their lousy efficiency, these light bulbs should be discarded, in favor of fluorescent light bulbs or LED light bulbs.In an old-fashioned light bulb, the part that emits light is a resistance.

How does an 25w compact fluorescent bulb provides the same amount of light as a 100w filament bulb but use less electricity?
It uses modern technology to give better efficiency. A filament bulb has an incandescent (hot) piece of tungsten wire, which produces light but also heat. A fluorescent bulb uses a different process to produce more light and less heat.
What year was the fluorescent light bulb invented?
The flourescent light bulb was invented in 1827.
what is the long thin light bulb called?
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.
What is the fluid in a fluorescent light bulb?
In a fluorescent light bulb there is usually a drop of mercury. That mercury vaporizes as the bulb warms up and it becomes gaseous, enhancing the electron interaction through the bulb, making it brighter.
