When should you replace a fluorescent light bulb?
when the tube ends blacken after failure of the tube heaters
The fluorescent light bulb was introduced in 1938.
The correct voltage should be printed on the light bulb.
Yes, an incandescent bulb uses more energy than a fluorescent bulb and a fluorescent light bulb lasts about 10 times longer.
Fluorescent is more efficient. Incandescent bulbs should not be used any more, except for some special purposes (mainly where they keep something warm).
EEdmund Germer (90% sure) made the first fluorescent light bulb
fluorescents are about 5x as efficient so a 12W will give about as much light
The weight of one 8 foot fluorescent light bulb is 1.2 pounds. Fluorescent light bulbs are available in many colors and color temperatures.
The light spectrum from an incandescent (a bulb) is closer to the spectrum of the sun than what comes from a fluorescent.
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).
The energy saving light-bulbs are usually fluorescent. Neon is a type of fluorescent light bulb.
You have a failing bulb or ballast.
Fluorescent by far.
By far the hottest of the two light sources is the light bulb.
fluorescent light bulbs are usually from 9$-15$.
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.
Light in fluorescent bulbs occurs when electricity excites the mercury vapor inside the tubular glass bulb.
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.

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.
No, the ballast's output is not matched to operate a fluorescent bulb.

A 15-watt fluorescent should produce about as much light as a 75-watt incandescent.
The shape of the glass envelope.
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.
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.

Compact fluorescent light bulb
It is about $3
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
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.
How do it replace the stop light bulb
A fluorescent tube does that.
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.
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.
An incandescent light bulb produces a lot of waste heat. Fluorescent lights do not get nearly as hot.
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.

yes he did
about 5 times as efficient.
