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.

∙ 10y agoThe luminous efficacy of a fluorescent light bulb can exceed 100 lumens per watt, this is four to six times more efficient than incandescent bulbs.
A typical 100 watt tungsten filament incandescent lamp may convert only 5% of its power input to visible white light, while typical fluorescent lamps convert about 22% of the power input to visible white light.

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
Who invented fluorescent light bulb?
EEdmund Germer (90% sure) made the first fluorescent light bulb
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 is the spectrum of fluorescent light?
light bulb
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 is a light bulb better for growing plants then a fluorescent?
The light spectrum from an incandescent (a bulb) is closer to the spectrum of the sun than what comes from a fluorescent.
What year was the fluorescent light bulb invented?
The flourescent light bulb was invented in 1827.
Why does a circular fluorescent light bulb not light up fully?
You have a failing bulb or ballast.
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$-15$.
The light-producing element in a fluorescent bulb is the?
Light in fluorescent bulbs occurs when electricity excites the mercury vapor inside the tubular glass bulb.
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.
