A bulb will last about six months before it needs to be changed again. Continuously turning a bulb on and off will decrease its' life span, however the average life span is about 5,000 hours per bulb.
Yes. The bulb will be slightly dimmer, but will last much longer. Most 145V bulbs are intended to be used in 120V exit signs. The reason for the higher voltage rating on the bulb is because it will last a long, long time when used at 120V.
Yes, absolutely. As long as the LED bulb and incandescent bulb have the same base they will both fit the socket. The LED bulb will also run much cooler than the original incandescent bulb.
Any lamp will take a light globe style light bulb as long as the fitting is compatible. There are many different kinds of light bulb like screw fit or bayonet style so you need to make sure you pick the correct type for your light fitting.
The actual amount of light (lumens) given off by a bulb depends on the how the bulb was made and with what materials. It depends on the filament material, its length and thickness, and the type of gas in the bulb. As a rule, longer lasting bulbs of the same wattage will generally be less bright than others and brighter bulbs of the same wattage will not last as long as other bulbs.Sample lumen outputs:Sylvania 250 Watt Indoor Soft White 3-Way Bulb can emit 3940 lumens at its highest setting.Philips 250 Watt 120 to 130V PAR38 Krypton Flood Bulb emits 3100 lumens
someone, but he IMPROVED the light bulb as well so... it wasnt the same for long
Thomas Edison's first successful light bulb lasted for about 13.5 hours when he first demonstrated it. However, he and his team later improved the design to last for over 1500 hours.
The mood light will last as long as the bulbs life, which has a lifetime of an average household light bulb. once the bulb burns out, one must replace the bulb with another mood light bulb.

Thomas Edison did not invent the light bulb but improved upon existing designs. He developed a carbon filament that could last longer and produce a steady light, leading to the invention of a practical and commercially viable incandescent light bulb. Edison's method involved creating a high vacuum inside the bulb to reduce the rate of oxidation of the filament, allowing it to glow for long periods.
The filament in Thomas Edison's light bulb was made of carbonized bamboo. Edison experimented with various materials before settling on carbonized bamboo as a durable and long-lasting option for the filament.

he improved the light bulb when he saw that it did not last long and broke easily
Edison's main problem was finding a long-lasting, practical filament material for the light bulb. He experimented with various materials before discovering that carbonized bamboo filament could last for up to 1200 hours. This solution greatly improved the practicality and success of the light bulb.
At the time of the light bulb's invention, the term of protection on a patent was 17 years.

A flourescent light bulb lasts between 6000 to 18000 hours.
