When should you replace a fluorescent light bulb?
when the tube ends blacken after failure of the tube heaters
When was the fluorescent light bulb created?
The fluorescent light bulb was introduced in 1938.
How many volts does a fluorescent light bulb need?
The correct voltage should be printed on the light bulb.
Does a regular light bulb use more energy than a fluorescent light bulb?
Yes, an incandescent bulb uses more energy than a fluorescent bulb and a fluorescent light bulb lasts about 10 times longer.
Which type of light bulb is more efficient light bulb incandesent or an fluorescent light bulb?
Fluorescent is more efficient. Incandescent bulbs should not be used any more, except for some special purposes (mainly where they keep something warm).
Who invented fluorescent light bulb?
EEdmund Germer (90% sure) made the first fluorescent light bulb
What watt fluorescent bulb can you use to replace a 60watt incandescent bulb?
fluorescents are about 5x as efficient so a 12W will give about as much light
What is the Weight of 8 foot fluorescent light bulb?
The weight of one 8 foot fluorescent light bulb is 1.2 pounds. Fluorescent light bulbs are available in many colors and color temperatures.
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.
Can one replace a tungsten bulb with a compact fluorescent bulb?
Yes, if it fits the socket and the light fitting, or lamp fixture, with its cover or shade. You will not be able to dim the compact fluorescent as you did the incandescent (unless you have a really fancy dimmer).
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.
Why does a circular fluorescent light bulb not light up fully?
You have a failing bulb or ballast.
What light bulb uses the least energy - incandescent compact fluorescent or a halogen bulb?
Fluorescent by far.
Which is hotter a fluorescent light tube or a light bulb?
By far the hottest of the two light sources is the light 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.
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.
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.
Fluorescent in a sentence?
I need to buy another fluorescent light bulb at the hardware store
Which type of bulb is more efficient incandescent or fluorescent?
A typical 20-watt compact fluorescent light bulb can produce about as much light as a 100-watt incandescent light bulb. There is an 80 per cent improvement in efficiency.
Can you use a 65 watt fluorescent bulb in a metal halide light fixture?
No, the ballast's output is not matched to operate a fluorescent bulb.
What is a word that means a light bulb that uses more energy than a fluorescent light bulb?
incandescent
How many 75 watt fluorescent bulbs are needed to give as much light as a 75 watt incandescent bulb?
A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.
What is the difference between an incandescent light bulb and a fluorescent bulb?
The shape of the glass envelope.
What is the weight of a four foot fluorescent light bulb?
The average fluorescent light bulb weighs about 3 to 5 ounces. That would make the weight of four of them to be about 12 to 20 ounces.
How is eletrical energy converted in light energy?
In an incandescent light bulb, the wire is heated until it glows. In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels. When they fall back, they emit light. In an incandescent light bulb, the wire is heated until it glows. In a fluorescent light bulb, atoms are excited, which means the electrons are raised to higher enerty levels. When they fall back, they emit light. In… Read More
How is an incandescent light bulb different from a fluorescent light bulb?
An incandescent bulb differs from a fluorescent based on how it produces light. "Incandescent" means producing light through heat, this is essentially how an incandescent bulb lights. As current travels to the tungsten filament, the filament heats and lights up as the tungsten filament begins to deteriorate and eventually fail. Fluorescent bulbs produce light when current excites gasses inside the glass envelope. As the gasses get excited they emit photons. Interestingly, the light produced by… Read More
What is a 6500K fluorescent bulb?
It's a bulb with more blue light in it, to better match the light that natural sunlight emits.
How efficient is a fluorescent bulb that emits the same amount of light as a 100w incandescent bulb?
It is about 5 times more efficient than the incandescent bulb, in other words for the same light a fluorescent uses one fifth the electric power.
What type of light bulb converts ultraviolet waves into visible light?
A fluorescent tube does that.
What are the advantages and disadvantages of a fluorescent light bulb?
The fluorescent light bulb more efficiently converts electricity to light resulting in less heat produced. But in winter, heat being produced is not exactly a bad thing. Besides, fluorescent light bulbs are more expensive and have heavy metals in them, making them more toxic.
Information on CFL light bulbs?
A compact fluorescent lamp (CFL), also called compact fluorescent light, energy-saving light, and compact fluorescent tube, is a fluorescent lamp designed to replace an incandescent lamp; some types fit into light fixtures formerly used for incandescent lamps. The lamps use a tube which is curved or folded to fit into the space of an incandescent bulb, and a compact electronic ballast in the base of the lamp.
Why does a light bulb waste energy?
An incandescent light bulb produces a lot of waste heat. Fluorescent lights do not get nearly as hot.
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. When current flows through it, it heats up so much that… Read More
