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.
LED light bulbs generally have a longer lifespan than incandescent light bulbs. LEDs can last up to 25,000 hours or more, while incandescent bulbs typically last around 1,000 hours.
Incandescent buls normally last 1000 hours, CFLs usually last 8000 or 12,000 hours. It's on the packet.

Which bulb lasts longer an incandescent light bulb or a compact fluorescent light bulb?
A compact fluorescent light bulb typically lasts longer than an incandescent light bulb. Compact fluorescent bulbs can last up to 10 times longer than incandescent bulbs due to their more efficient design and reduced heat production.
How long does a standard incandescent light bulb last?
A standard incandescent light bulb typically lasts around 1,000 to 2,000 hours. This can vary depending on usage patterns and the quality of the bulb. LED bulbs, for example, can last significantly longer than incandescent bulbs.
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.
What is the life span on these 250 watt bulb?
The lifespan of a 250 watt bulb can vary depending on the type of bulb (incandescent, LED, etc.) and its usage. Generally, incandescent bulbs have a lifespan of around 1,000 hours, while LED bulbs can last up to 25,000 hours or more. Regular maintenance and proper usage can also affect the longevity of the bulb.
Is all the air vacuumed out of a light bulb or is special air pumped in?
In a light bulb, the air is typically vacuumed out to create a vacuum or low-pressure environment inside the bulb. This helps to prevent the filament from burning out too quickly and improves the efficiency of the bulb. Sometimes, inert gases like argon or nitrogen are used instead of a vacuum to prolong the life of the filament.
Which bulb lasts longer an incandescent light bulb or a compact fluorescent light bulb?
A compact fluorescent light bulb typically lasts longer than an incandescent light bulb. Compact fluorescent bulbs can last up to 10 times longer than incandescent bulbs due to their more efficient design and reduced heat production.
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.
Is argon used in a light bulb?
Yes, argon gas is commonly used in incandescent light bulbs. It helps prevent the tungsten filament from oxidizing and prolongs the bulb's life.
Which kind of lamps have longer lifetime led lamps or incandescent light bulbs?
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.
Why is krypton used in light bulbs?
Krypton is used in certain types of incandescent light bulbs because it helps prolong the life of the filament inside the bulb by reducing its evaporation. This allows the bulb to emit light for a longer period of time before burning out.
How long does a standard incandescent light bulb last?
A standard incandescent light bulb typically lasts around 1,000 to 2,000 hours. This can vary depending on usage patterns and the quality of the bulb. LED bulbs, for example, can last significantly longer than incandescent bulbs.
Is the original thomas Edison light bulb still used today or has it been modified to something that you have today?
The original design of Thomas Edison's incandescent light bulb has been improved upon over the years, leading to more efficient and longer-lasting bulbs. Today's light bulbs use different technologies such as LED and CFL, which are more energy-efficient and environmentally friendly compared to the original incandescent bulbs.
How did the invention of the incandescent light bulb in 1879 change the way people interacted with their physical environment?
The invention of the incandescent light bulb revolutionized daily life by extending the hours of productivity and leisure people could enjoy after sunset. It paved the way for safer and more efficient lighting in homes, workplaces, and public spaces, ultimately improving quality of life and enabling activities to take place more comfortably and efficiently at all hours.
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.
What gas is used inside a light bulb?
Argon gas is commonly used inside incandescent light bulbs to prevent the filament from oxidizing and burning out. It helps to prolong the life of the bulb by reducing the evaporation of the filament material.
