It depends on the quality of filament, how often it is switched on and off and fluctuations of supply voltage.
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.
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.

An LED light bulb can last up to 25,000-50,000 hours, depending on the quality of the bulb and usage. This makes them much more durable and long-lasting compared to traditional incandescent or CFL bulbs.
For a standard household incandescent it is 200w. Mogul incandescents can reach 3-500w depending. Halogen tubes typically reach 500w. Sodium-halide , high pressure sodium , Mercury vapor , and Arc lamps can reach into the thousands of watts but are not usually used in a household setting.

Thomas Edison made the first operating incandescent light bulb. But in 1800, Humphrey Davy invented the electric light. It didn't last long, and was not a bulb, though. Arc lights later became popular, but again, were not in a bulb.
Fluorescent light bulbs are more energy-efficient and last longer than traditional incandescent light bulbs. They also produce less heat and can save you money on your electricity bill in the long run.
It depends on the design of the bulb. Typical incandescent bulbs last between 750 and 1000 hours of operation.
It depends on the quality of filament, how often it is switched on and off and fluctuations of supply voltage.
Fluorescent tubes last longer and supply more light per watt of energy consumed than an incandescent bulb.
Thomas Edison replaced the filament in his incandescent light bulb with a carbonized bamboo filament in 1880. This improvement helped the light bulb last longer and shine brighter.
Fluorescent light bulbs use gas and phosphor coating to produce light, while incandescent light bulbs use a filament that heats up to produce light. Fluorescent bulbs are more energy-efficient and last longer than incandescent bulbs, but they may have a flickering effect and contain small amounts of mercury. Incandescent bulbs are cheaper upfront but have a shorter lifespan and are less energy-efficient.
The lifespan of a light bulb varies depending on the type of bulb and how often it is used. Typically, incandescent bulbs last around 1,000 hours, while LED bulbs can last up to 25,000 hours or more. Factors such as wattage, quality of the bulb, and usage patterns all contribute to how long a light bulb will last before burning out.
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.
Average of 4000-6000 hours. Domestic 'general service' incandescent tungsten bulbs are generally rated at 1,000 hours, but may last longer. 'Low energy' compact fluorescent lamps are rated 6,000 to 10,000 hours, mainly according to price - read the box.
