It depends entirely on the bulbs being compared. There are some very bright fluorescent bulbs. In some Compact Fluorescent Lamps (CFL) they take longer to get to full brightness. Also the frequency of the light emitted has a lot to do with the brightness the eye perceives.

Which bulb lasts longer an incandescent light bulb or a compact fluorescent light bulb?
A regular incandescent bulb uses a lot more energy than a compact fluorescent to produce the same amount of light. Most energy used by an incandescent bulb is wasted as heat which does not give off visible light. Incandescent bulbs are cheaper to buy, but they have shorter lifetimes than other alternatives.
What is the main difference between an incandescent light bulb and compact fluorscent 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 a fluorescent bulb does not fall along the visible spectrum until it passes through the white, phosphor coating on the inside of the bulb. And there you have it.
Why does a light bulb filament act as resistor?
The filament of a light bulb isn't like a resistor ... it is a resistor. The only difference from the ones on circuit boards is the it's designed to operate at a much higher temperature. So hot that it glows. The glass envelope is there to prevent oxygen from getting in and promptly burning it. When the filament becomes too hot it breaks breaking the current that was lighting it in the first place. That is why the light bulb "burns" out.
What are pros and cons of a fluorescent light bulb and regular light bulbs?
Not as bright as normal light bulbs (higher watts though)
Why use incandescent lights on the plants?
As a single light source for plants, incandescent light bulbs are not particularly good. They are a good source of red rays but a poor source of blue. They produce too much heat for most plants and, if used, must be located some distance from the plants, thus reducing the intensity of the light the plants receive. They are also about one-third as efficient as fluorescent tubes in converting electrical energy to light. Furthermore, a standard incandescent bulb's life is often only about 1,000 hours, whereas a fluorescent tube's life is normally 10,000 hours or more. Fluorescent tubes provide one of the best artificial light sources available for plants in the home. Other light sources such as sodium-vapor and metal halide lamps may be used but are not as readily available or adaptable for home use. Hope this was the answer you were looking for.

Which kind of lamp have longer lifetime LED lamps or incandescent bulb?
Of course，LED light has longer life compare to incandescent light，because its lighting principal is semiconductor Lighting，which can turn the most electricity into lighting，the average life is 50000 hours，such as LED tube light and LED floodlights.
How long is the life of an incandescent light bulb?
Usually around 900 hours.
How did the incandescent light bulb change life?
it made it so people can see in the dark.

How are CFL light bulbs better than regular light bulbs?
A CFL uses 65% less energy and can reduce your power bill as well.A longer answerSince major improvements in the design of Compact Fluorescent Lamps (CFLs) from 1990 onwards, by using a CFL light bulb 80% energy of the energy can be saved compared to the energy that is needed to produce a given amount of artificial light using conventional incandescent filament bulbs.In other words, to produce the same amount of visible light, a modern CFL uses only 1/5 (one fifth) of the power that an incandescent filament bulb uses.For example, a 20 watt CFL bulb produces similar light to a 100 watt incandescent filament bulb and a 30 watt CFL matches the light output of a 150 watt incandescent filament bulb.CFLs also have a much longer useful life-span, thus avoiding the need to change them as often as incandescent light bulbs.Another opinionThere are issues with the additional power used to manufacture CFL bulbs and the toxic chemicals inside these units.But, whilst they certainly do save energy for the end user, their drawbacks are that they probably use more energy overall and their manufacture causes more pollution.
Replacing Old Light Bulbs with CFLs?
Upgrading to an energy smart home starts with replacing all of the old incandescent light bulbs with compact fluorescent lights, commonly abbreviated as CFLs. When buying new light bulbs, the most important specifications to look for include luminosity, bulb life, and power. The intensity of the light is measured in Lumens while the power is rated with Watts. In general, a CFL with about five times lower watt rating than an incandescent bulb can offer the same luminosity as the older bulb.
What are the advantages and disadvantages of the light bulb?
-Compact fluorescent bulbs use 66% less energy than a standard incandescent bulb, and last up to 10 times longer. -A 32-watt CFL can save a homeowner $30 in energy costs over the life of a bulb. -Lower weight and size, has a more attractive shape. -Easier and less frequent replacement. -Less maintenance cost.

How does the light bulb improve qualities of life for people?
The light bulb improve the quality of life by, it was easier for people to see around their house. The light bulb used less energy and would last longer. Wouldn't have to use windows orlanterns as your light. You could use it in the dark. More goods are produce.... Meaning workers had to work longer and get better pay. More safe when you are in the dark you could see and know what you are doing, was safer.
How do you use the Light bulb?
we use the light bulb in every day life
What did Tomas Edison do in life?
he invented, (note: he didn't invent the light bulb he just improved it by making it last longer
