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.
What is a word that means a light bulb that uses more energy than a fluorescent light bulb?
incandescent
How does a compact fluorescent light bulb work?
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.
Is compact fluorescent light the best energy saving bulb?
No, the most energy efficient bulbs are LED (Light Emitting Diode) light bulbs.
What is the energy reducing light bulb called?
They are called CFL light bulbs. CFL stands for Compact Fluorescent Light .
Who invented fluorescent light bulb?
EEdmund Germer (90% sure) made the first fluorescent light bulb
Which light bulb uses more energy?
Incandescent and halogen light bulbs use more energy than compact fluorescent lights and LED lights. Fluorescent lamps with magnetic ballasts use more energy than fluorescent lamps with electronic ballasts.
What is the spectrum of fluorescent light?
light bulb
How much energy does an incandescent lightbulb use versus a fluorescent?
Yes that's true fluorescent bulbs are better because it usess 75% less energy and works longer than a incandescent light bulb. Yes...and no. It is true that power usage decreases with fluorescent balb usage. However, one must take into account that they pollute more (i.e. mercury and other heavy metals).
How do you know a light bulb transforms 100 percent of its electricity into light?
You don't. A light bulb transforms only a fraction of its energy into light, and most of it into heat. For an incandescent bulb about 3% is transformed into light, while for a compact fluorescent (low-energy light) about 15% is transformed into light.
Why is a low energy light bulb described as more efficient than a normal light bulb?
Because efficiency is measured in Output/input. At the same light bulb output, one with lesser energy input required is higher in efficiency. Possible confusion come from description of low energy light bulb without stated the high or low energy is compared at what lux it can produce light.
What is the input or output of the light bulb?
Input to light bulb is Electricity and output is light.
